What Did UK Dentists and a Peer-Reviewed Review Report About Problems After Dental Treatment Abroad?

What did the BDA report its members observed?

The British Dental Association surveyed dentists in the United Kingdom about patients returning from dental treatment abroad, and the association names the sample in its own words before it gives a single figure: "According to a survey of 1000 UK dentists in the UK:". Everything that follows in that report is a record of what dentists said they had seen in their own surgeries, not a count of patients and not a study of Turkey. The association reports that "86% reported having treated cases that developed problems following treatment abroad", and that "87% identified crowns as the treatment most likely to require follow-up work, closely followed by implants at 85%". Each of those figures is a share of dentists who flagged something. Read as a share of patients whose teeth failed, it would state something the survey never measured.

Among the problems those dentists named, the British Dental Association's report places one above the rest: "The highest single risk factor identified was failing or failed treatment (86%), closely followed by pain (76%), and poorly executed treatment (72%)." The three figures sit in one sentence and are ordered by how often dentists selected them, which makes the sentence a ranking of professional concern rather than a table of incidence. No patient count, no tooth count and no time window is attached to any of the three. A reader who wants to know how often teeth fail after treatment abroad will not find that answer in this sentence, and the sentence does not offer it. What it does establish is which problem the largest share of surveyed dentists put first when they were asked.

Descriptions rather than percentages carry the clinical detail in the same report, and the association writes them as observations reported by its members. One sentence reads: "Several dentists reported concerns about over-prepared teeth – where more of a tooth is removed than necessary – as well as ill-fitting crowns and implants that fell out." Another reads: "Others were worried that treatment proceeded despite having untreated gum disease, which was likely to increase the risk of crowns and implants failing, as well as being a major contributor to infection and pain." Both sentences report what dentists said they saw in front of them. Neither is a diagnosis, and nothing on this page tells any reader what their own teeth need or what any particular symptom means.

Two individual accounts appear in the association's report with numbers attached to them, and they are presented as things single respondents described rather than as typical outcomes. One dentist reported a young man who had 21 full crowns inappropriately placed to manage, in that dentist's words, "what was clearly an orthodontic case to correct misaligned teeth." The second account is quoted in full: "Another said that they saw a patient with dental phobia who had 14 crowns placed under sedation, and who now needs four root canal treatments." The report records a wider version of the same worry, writing that some dentists "expressed alarm that patients had extensive work done to previously healthy teeth" in what it calls "smile makeovers", work "which would require a lifetime of costly maintenance, or could even lead to the loss of teeth and a need for dentures." Single accounts are evidence that something happened at least once, which is not evidence about how often it happens.

On what putting things right costs, the British Dental Association reports its members' estimates rather than invoices: "Two-thirds of respondents (65%) said that it cost patients at least £500 to repair the damage done to their teeth, while over half (51%) reported that it was more than £1,000. One in five of these dentists said the cost exceeded £5,000." One further sentence carries both a proportion and a headcount: "Over 40% (346 dentists) said the remedial treatment was provided by the NHS." These are recollections of what repair cost patients, given in pounds by the dentists who did the repairing. No corresponding figure for what the original treatment cost appears anywhere in the report.

How recent the cases were, and which way the surveyed dentists thought the trend ran, are stated separately in the same British Dental Association report: "Over half (56%) reported seeing cases in the past three years, with a fifth (20%) seeing cases during the pandemic" and "84.6% state dental tourism is a growing trend." One boundary belongs beside all of it, and stating it is ours rather than the association's: the survey asked about dental treatment abroad, and the word Turkey does not appear anywhere in the report page we read. Moving these figures onto a single destination would be doing something the survey did not do, and we do not do it here.

The association closes that report with a position of its own and with a named person stating it. It writes that "The BDA is calling on the authorities to provide genuinely proactive campaigns to ensure patients are aware of the potential risks", and it quotes its chair, Eddie Crouch: "We strongly advise people considering this to check a dentist's qualifications and experience and whether they are insured if things go wrong." That is advocacy from a professional body about a policy gap, and we record it as advocacy. It is not a clinical finding, and it is not evidence about outcomes in any country.

What do those percentages measure, and what is the denominator?

Percentages in the British Dental Association's report on treatment obtained abroad do not all share one denominator, and the association changes it inside the same document. The outer base is stated plainly: "According to a survey of 1000 UK dentists in the UK:". An inner base is then introduced immediately before the headline figures: "The appeal of travelling abroad for dental treatment appears to be widespread, with 94% reporting that they had examined patients who had gone on such trips: however, the findings indicate that the lure of a quick fix may carry considerable risks. Of these dentists:". The figures that follow that colon are therefore shares of the BDA's 94 per cent, not of the full thousand. Quoting them as shares of all dentists, or as shares of patients whose teeth failed, states a different number from the published one.

A second denominator appears a few sentences later in the same report, and this one is explicitly the whole responding sample: "93% of all dentists responding identified concerns around continuity of care, 79% were unhappy with the quality of care, 77% mentioned the difficulties associated with seeking redress or making a complaint, while 66% flagged concerns over communications between patients and practitioners." The phrase about all dentists responding does work that the report's other lead-in — the sentence ending "Of these dentists:", whose base is the BDA's 94 per cent who had examined patients who went abroad for treatment — does not. Two blocks of percentages in one document therefore rest on two different bases, and the only way to tell which is which is to read the sentence that introduces each block rather than the percentages themselves.

One sentence in the report gives both a proportion and a headcount, and it is the only absolute number the document contains: "Over 40% (346 dentists) said the remedial treatment was provided by the NHS." Arithmetic on the association's own figures belongs here, marked as ours: 346 out of the 1,000 the same BDA report names is 34.6 per cent, which is not over 40 per cent. The count and the proportion therefore reconcile only against some base smaller than the full sample, and the report does not say which base that is. We do not resolve it by choosing one, because choosing one would turn an unstated denominator into a stated one on our authority rather than on the association's.

Reporting of this same survey differs between two of the association's own pages, and both are the association's. The BDA's media centre report gives the examination figure as 94 per cent, while its news page writes: "95% of dentists reported that they have examined patients who have travelled abroad for dental treatment." The stated sample moves as well: "According to a survey of 1000 UK dentists in the UK:" on the first page against "Over 1,000 dentists responded to our survey, and the results are shocking:" on the second. A one-point difference between two readings is small in itself. A source that disagrees with itself is not, because it means neither version can be quoted as settled.

Worse than a rounding difference is a number that changes what it counts as it moves between pages, and one figure in this set does exactly that. The media centre report attributes it to dentists: "Cheaper costs were identified by 98% of all respondents as the lead factor influencing patients' decisions to seek dental care abroad, while almost a third (31%) of those surveyed said that a perception of shorter waiting times was responsible." The BDA's priorities page renders the same 98 per cent as a fact about patients: "98% of patients are chasing cheaper treatments." Respondents in this survey were dentists. The second wording is therefore unusable for that figure, and this page does not use it.

What no version of the report publishes is the method behind any of these numbers, and that absence was measured rather than assumed. Across the full text of the three British Dental Association pages held in our working directory — the media centre report, the news article and the priorities page — the word roots for method, sample, response rate and weighting return no matches at all. The sampling frame is therefore unstated, the response rate is unstated, and whether the results were weighted is unstated. None of that makes the figures wrong. It means they cannot be checked, which is a narrower claim than calling them unreliable, and the narrower claim is the one the evidence supports.

Something does survive all of that, and it is worth saying so rather than leaving the section as a list of objections. A professional body asked its own members a question and published the answers, and the answers are consistent across three of its pages in direction even where they differ in the second digit: a large majority of the dentists who responded said they had seen patients who travelled for treatment, and a large majority of those said they had treated problems afterwards. That is a real finding about what United Kingdom dentists encounter. It is simply not the finding a reader would take away from a sentence that turned it into a percentage of patients, or of teeth, or of one country's clinics.

What did the BDJ review find about which country the media focused on?

Doughty J, Moore D, Ellis M and colleagues published a review of United Kingdom news coverage of dental tourism in the British Dental Journal, the peer-reviewed journal of the British Dental Association, in 2025, and its central sentence about Turkey is a finding about newspapers rather than about dentistry: "Almost all of the articles about post-operative complications were Turkey-centric, primarily because the media were focusing on social media accounts using #TurkeyTeeth, as opposed to Turkey specifically being implicated in providing substandard dentistry." The review is open access, its full text sits in PMC under the identifier PMC11870843, and it appeared as British Dental Journal 2025;238(4):230-237 under DOI 10.1038/s41415-025-8330-2, so that sentence can be checked against the paper rather than against this page.

What the review examined is set out in its methods section, and the boundaries are narrow enough to matter. Newspaper articles were identified using the LexisNexis database. The ten most popular newspapers in the United Kingdom were used for the search strategy, with popularity based on circulation and online readership. The timeline recorded in PMC11870843 ran from 1 January 2018 to 31 May 2023, and the search string covered ten phrasings, of which the treatment nickname was one and dental tourism another. The review reports: "The search strategy identified 201 newspaper articles related to dental tourism. A total of 131 articles were included in the analysis". The unit of study is a newspaper article. It is not a patient, a clinic or a tooth.

Where those articles appeared is reported precisely, and the concentration is heavy. The review states: "Ten articles (7.6%) were published in broadsheet newspapers. The remaining articles (92.4%) were published in tabloid newspapers, and of these, 106 (80.9%) were published in either The Sun or a newspaper linked to The Mail (eg Daily Mail, MailOnline etc.)". Its table of publication years is just as uneven: none in 2018, one in 2019, twelve in 2020, none in 2021 — the counts are in PMC11870843 — then fifty-nine in 2022 and fifty-nine in 2023. The review records that those two peak years coincided with the publication of dental contract reforms, the emergence of a hashtag on TikTok and the release of a television programme on the subject in July 2022 (DOI 10.1038/s41415-025-8330-2). Whatever this pattern measures, it measures the behaviour of a small number of publications concentrated into two years.

Terminology was measured in the same review rather than assumed, and the result cuts against treating the nickname as either the media's standard word or the profession's. The paper reports: "This investigative search revealed that terminology used by the media differs from that used by the dental community. For example, newspaper articles tended to use phrases such as ‘dentistry overseas' or ‘dentistry abroad'. Contrastingly, dental articles or newspaper articles offering advice from dental professionals commonly used the phrase ‘dental tourism'." Two vocabularies, two communities, and the phrase a reader is most likely to have encountered belongs to neither of them as a technical term. The review reached that result by hand searching fifty news articles and running an academic search before it fixed its own search string, which is why the finding is reported as a measurement rather than as an impression.

Judgement on the label itself is explicit in the review, and it is a judgement about fairness rather than about clinical standards: "The convenience of collectively placing all overseas dentistry within this category should be acknowledged as both unfair and inappropriate, and yet has become a recognised colloquial term in the zeitgeist for what is otherwise a difficult-to-define and complex social phenomenon." The same paper records what its corpus did not establish: "There is no objective evidence to show that the majority of patients travelling abroad for care experience exploitation or poor clinical outcomes and little evidence-based reflection on the comparative risks of similar issues occurring while seeking care in one's own country."

Why the coverage clustered where it did is answered in the same review, and the answer names a hashtag rather than a country's dentistry. Many of the articles reviewed focused on the viral hashtag #TurkeyTeeth, which the paper (PMC11870843) records as carrying 700.8 million views on TikTok and 18.2k Instagram posts at the time of writing. The review also states how the articles treated the people in them: "Many articles in this study were distinctly stigmatising of people seeking and suffering from the consequences of dental tourism." A concentration of coverage produced by a hashtag is a fact about attention. It is not a measurement of outcomes anywhere.

Limits of the review are stated by its own authors in PMC11870843, and they bound what anyone can carry away from it. The paper writes: "A limitation of this study is that the data were limited to the ten newspapers with the highest print and online readership. We did not include data from non-newspaper sources, such as the BBC website, or television." It adds: "The date of the search is up to May 2023." and "The study is UK-centric and the findings may lack transferability to other cultural contexts." A study of what ten newspapers printed up to that date cannot describe what treatment in any country is like today, and this one does not claim to.

What did the review report about follow-on care and legal redress?

Concerns about what happens after the work is finished ran across the newspaper corpus that Doughty J, Moore D, Ellis M and colleagues reviewed for the British Dental Journal in 2025 — a corpus whose complication coverage the same review describes as Turkey-centric — and the paper states those concerns in a single sentence: "The lack of regulatory processes and absence of access to legal redress or follow-on care was a common concern across the articles." The review is open access in PMC under the identifier PMC11870843. What that sentence records is what the articles raised, not what any law provides, and a common concern in a press corpus is in the first instance a fact about the press.

Who provided the repair, according to the same review, split two ways. The paper writes: "A few articles described remedial care as being provided by the NHS, while other private providers described actively avoiding the provision of care for people who'd had dentistry abroad because of fear of liability". It then reproduces, as data, a comment attributed in the paper to the director of a dental clinic in Liverpool: "If I did 20 crowns on a 21-year-old for the purpose of improving the colour, I would have my licence revoked, I would be struck off […] at the point you inherit that patient and do any work, that's when the problems really start and that's when the UK dentist becomes liable. A risk we cannot take". That is one named role in one article, and it is a statement about liability rather than about clinical quality.

On what the health service will and will not fund, the review cites an older position: "The Department of Health has previously indicated NHS responsibility to provide emergency care, but not remedial care (eg elective revision), for cosmetic procedures provided outside of the UK." One boundary has to travel with that sentence, and stating it is ours: the review builds the point on cosmetic surgery literature rather than on dentistry-specific policy. The sentence is therefore reported here as the review's summary of a position, with the sourcing limit attached to it, rather than as a current statement of what NHS dentistry does for a patient who returns with a problem.

The review's own conclusion on this point names litigation as the mechanism: "The UK dental profession strongly advocated for minimally invasive approaches and the risk of litigation discouraged treatment of people who required remedial care following dentistry abroad." It reproduces a working clinician's description of the same gap, attributed in the paper to an NHS dentist: "It's shocking people have no clue what they've done. They talk about veneers - mouldings bonded to the front of a tooth - but in reality, they are crowns, meaning much more aggressive tooth reduction". Both sentences describe a reluctance to take the work on. Neither of them says the work cannot be taken on, and the difference between those two claims is the whole of the practical question.

Where this leads in policy is the part of the review most often dropped from summaries of it. The paper records: "This has led to some professional attitudes promoting a policy position that would prevent those who have paid for dental work overseas from accessing publicly funded dentistry." It answers that position with a comparison: "There are no similar calls to prevent those who have extensive or expensive care provided privately at home and who then become unable to self-fund maintenance or remediation of dental treatment from accessing care." The review is arguing about consistency between two groups of patients, and this page quotes that argument rather than adopting it.

A distinction the review presses is worth separating out, because redress looks different on either side of it. The paper argues that dental tourism should be broken into two components — travel that provides access to routine dental care, and travel undertaken for purely cosmetic reasons — and reports that the journalism it examined failed to recognise that split. Someone who could not obtain routine care at home and someone who chose an elective change in appearance are in different positions when something needs putting right. The review's complaint is that the press coverage it studied treated both as a single story.

What none of these sentences supplies is a rate. The review counted newspaper articles and analysed their themes; it did not follow patients, and its own description of its design says as much. A common concern across a press corpus tells a reader that the concern was raised often in print. It does not tell them how often redress was actually refused, how often follow-on care was actually declined, or how either of those figures would compare with the same questions asked about treatment obtained at home.

What does NHS England's policy say a patient can access after a complication?

NHS England published a clinical policy in November 2024 that answers this for a patient who paid for dental treatment themselves, in Turkey or anywhere else, and its operative sentence reads: "Patients who have previously paid for dental treatment privately in the UK or abroad but later require NHS treatment due to a complication or sudden oral health issue are entitled to access NHS dental care for assessment and evaluation to stabilise their condition." The document is titled "Avoidance of doubt: Clinical policy for self-funded dental treatment requiring NHS intervention", carries publication reference PRN00784, and was published on 4 November 2024 and last updated on 6 November 2024.

Scope of that policy is written into its opening sentence, and it covers this situation by name rather than by inference: "This note sets guidelines for when it is appropriate to provide NHS dental care after patients have received self-funded dental treatments, including privately funded non-NHS care within and outside of the UK, in cases where patients have acute presentations or complications." A second sentence settles the eligibility question on its own: "Where a patient has received their care previously does not impact on their eligibility for NHS care in the future." The policy draws no distinction anywhere in its text between one destination and another, and it names no destination country at all. It sets out its own basis in one line, citing the NHS Constitution and the principle of providing appropriate care where needed, and it states that "The NHS will provide the treatment necessary to secure and maintain the patient’s oral health."

Where a person may go is listed rather than left open. The policy states: "Patients may present directly to primary or secondary dental or medical care settings, or via 111 urgent assessment and referral." It then sets out a sequence in numbered steps: patients are assessed and diagnosed, an acute management plan is formulated to meet the immediate and reasonable oral health needs of the patient as deemed necessary by the clinician, pain and infection are addressed with treatment referred to the appropriate care setting according to local NHS acceptance criteria and care complexity, and the sequence ends once urgent care has been addressed and stabilisation has been achieved.

Where the policy stops is stated in the same document and in the same plain register: "Please note that self-funded care that the NHS would not routinely fund would not usually be offered or replaced once stabilisation has been achieved." For anything beyond that point it writes: "Should the patient request/require further reparative or reconstructive elective care, the provision of care and choice of care setting would be subject to NHS acceptance criteria with reference to the complexity of need." Complex reconstructive work is singled out — the policy names advanced multi-unit fixed appliances and implants as its examples — and made subject to trust-based policies, existing NHS acceptance criteria, treatment-specific guidelines and NICE guidelines.

Who is expected to deal with the problem first is answered before the NHS route is described at all: "It is expected that patients would initially seek support from their self-funded dental care provider, who should be responsible for any post-treatment clinical issues within a reasonable timeframe." No number is attached to that phrase. The policy carries no numbered period anywhere in its text, and the phrase about a reasonable timeframe is the only expression of duration it contains. A reader trying to work out how long a clinic remains responsible for its own work will not find a figure in this document, because the document does not supply one. That is a measurement of the text rather than a reading of it: the scan covered the policy in full, and the commands and the corpus are kept in our working directory so it can be repeated against us.

Two questions are easy to merge at this point and the policy answers only one of them, which is our reading of its scope rather than a sentence it contains. Eligibility for NHS assessment and stabilisation after a complication is settled by the text quoted here, in one direction and without qualification about where the original work was done. Whether finished cosmetic work will be redone at NHS expense is a separate question, and the policy touches it only by pointing at acceptance criteria for elective reconstructive care rather than by granting or refusing anything. We mark that as our reading because it is a statement about what the document leaves open, not a quotation from it.

What is published about how often complications occur?

Published complication rates for this kind of work exist, but they are rates for procedures rather than for destinations, and nothing quoted on this page measures how often something goes wrong in Turkey specifically. Two peer-reviewed systematic reviews published in 2025 carry the figures used here, each identified by a DOI registered with Crossref. The first — Klein P, Spitznagel FA, Zembic A and colleagues, J Esthet Restor Dent 2025;37(3):601-619, DOI 10.1111/jerd.13351 — reports: "Complication rates (technical/esthetic/biological) were as follows: Feldspathic: 41.48%/19.64%/6.51%; LRGC: 29.87%/17.89%/4.4%; LDS: 6.1%/1.9%/0.45% at 10.4 years." Three materials, three different answers, and the abbreviations are the review's own rather than ours.

Spread inside that single sentence is the reason no one can quote a complication rate for this kind of restoration as a number. The technical complication figure the review — DOI 10.1111/jerd.13351 — reports for one material is 41.48 per cent and for another 6.1 per cent; dividing one by the other gives a factor of just under seven, and that division is ours rather than the review's. Both figures come from the same paper and are reported at the same follow-up. A page that told a reader the complication rate was some single percentage would be choosing one of these figures and hiding the others, and the choice would be doing all the work.

One number in that sentence is a period rather than a rate and deserves separating out: the review, DOI 10.1111/jerd.13351, reports its percentages at 10.4 years. A complication figure quoted without the follow-up attached to it is not comparable with anything, because the same restorations measured at two years and at ten will not return the same answer. Anyone repeating a percentage from a study of this kind without the period beside it has dropped the half of the finding that makes it mean something, and the drop is usually silent.

Implants are counted differently again, and by a different research group. Galarraga-Vinueza ME, Pagni S, Finkelman M and colleagues, in J Periodontol 2025;96(6):587-633, DOI 10.1002/JPER.24-0154, draw on 102 studies covering 13,030 patients and report: "Prevalence rates at the patient level for peri-implant mucositis and peri-implantitis were 46% (95% confidence interval [CI], 41-51) and 21% (95% CI, 17-24), respectively." The unit there is the patient; the unit in the restoration figures is the restoration. Two numbers measured on different units cannot be added, averaged, or set against each other as though they answered one question.

None of these figures is about a country, a clinic or a price band. They are pooled results from studies of restorations and implants wherever they happened to be placed, and neither review sorts its studies by where treatment was carried out. Reading them as an answer to how often treatment abroad fails would import a comparison that neither review made and that neither set of data supports. The honest form of the sentence is narrower: this is roughly what published research reports about these procedures in general, and no source quoted here reports it for one destination.

Survey figures from professional bodies are sometimes read as incidence rates, and that reading does not survive contact with what the surveys asked. When the British Dental Association reports that 86 per cent had treated cases that developed problems after treatment abroad, that percentage sits under the report's own lead-in "Of these dentists:", which narrows its base to the BDA's 94 per cent who reported having examined patients who had gone abroad for treatment rather than to the full thousand. Either way the denominator is dentists — not patients, and not teeth. A dentist who saw one such case in five years counts once, and so does a dentist who saw fifty. The figure describes how widely a problem is encountered across a profession. It cannot be converted into how often the problem occurs among the people who travelled.

Both reviews do answer something, and it is worth naming what rather than leaving them as a list of caveats. Between them they establish that complications after this kind of work are common enough to be measured in double-digit percentages for some materials and some outcomes, that the figures vary enormously with what was placed and with how long the patient was followed, and that the peri-implant figures in DOI 10.1002/JPER.24-0154 rest on 102 studies and 13,030 patients rather than on a handful of cases. A reader deciding whether complications are a real category of risk has an answer from published research. A reader looking for a single number attached to a single country does not, from these or from anything else quoted here.

What would answer the frequency question is a study that follows a defined group of patients who travelled for treatment and reports how many developed complications over a stated period, against a comparison group. No such study is held here, and one will not be assembled out of the sources that are. Recording the gap is more useful than filling it, because a gap of this shape is exactly where a confident-sounding number is easiest to invent and hardest for a reader to check.

How far apart do two keyword tools read this phrase in the UK?

Two keyword tools we use disagree about how often the phrase turkey teeth gone wrong is searched in the United Kingdom, and under the rules our methodology page sets out both readings are published rather than one of them chosen. The tool with no Iraq country database puts that phrase at 2,900 monthly searches in the United Kingdom. The tool that covers Iraq puts the same string, in the same market, at 80. The two readings are therefore roughly 36 times apart, and we do not know which of them is closer to reality. Both tools do return a difficulty score in single digits for the phrase, which is the one point where they sit close together.

Neither reading is presented here as the correct one, and the two are not averaged. Our archive holds three readings of this phrase from the tool with no Iraq database — 210, then 3,600, then 2,900 — so that instrument's own series moves across time as well as against the other tool, and quoting one figure from it means quoting a date along with it. What each tool returns alongside its volume, and why we name the two by country coverage rather than by brand, belongs to the measurement itself and is not re-derived on this page.

What a disagreement of this size cannot do is tell anyone anything clinical. A search volume is a count of typing, not a count of outcomes, and the distance between 2,900 and 80 is a distance between two commercial estimates of typing. The reason it sits on this page is narrower than it might look: a reader who meets this phrase somewhere and wonders whether it stands for a large body of concern should know that our two instruments do not agree on how much typing there is, and that we cannot say which of them is right.

How much demand a phrase carries and how often the thing it names happens are separate questions, and only the first is answerable with tools of this kind. A phrase can be typed heavily because a television programme used it, because a hashtag carried it, or simply because it is memorable, and none of those routes requires that the underlying event be common. Treating a keyword figure as evidence of frequency would be a category error, and it is one this page declines to make. The fuller account of this measurement — how the same comparison behaves in French and Arabic, what the two tools return for neighbouring phrasings, and the other places in our data where the two disagree — is set out on our separate pages about the English search gap and about why our two keyword tools disagree, and the two readings recorded here are the part of it this question needs.

Where does this page stop?

Nothing on this page ranks anyone, under the independence rules our editorial standards page sets out. No clinic or agency is named anywhere on it, in Turkey or in the United Kingdom; the only dentist named is the one who wrote the page, at its foot, and there is no route from here to booking anything. We are not a clinic and not an agency, we sell no treatment, we take no commission, and no clinic can pay to appear here. Every clinical-sounding statement above is either a quotation from a named regulator, professional body or peer-reviewed journal, attributed where it stands, or a reading of ours that goes beyond a quoted sentence.

One conclusion this page deliberately does not draw is a judgement about dental treatment in any country. The sources quoted here do not support one, and the peer-reviewed review among them says so in its own words, describing the concentration of complication coverage on Turkey as a product of media attention to a hashtag rather than as evidence that Turkey was providing substandard dentistry. The same review calls the practice of collecting all overseas dentistry under one label both unfair and inappropriate. A survey of what dentists in one country have seen, and a study of what newspapers in that country printed, cannot between them establish the quality of care in another.

A second thing this page cannot tell a reader is how often problems occur. No source held here measures that for people who travelled for treatment. The professional-body percentages count dentists, the peer-reviewed complication rates are pooled across procedures rather than destinations, and the review of press coverage counted articles. Three different units, none of them the one that would answer the question. Writing that sentence is better than assembling a number out of parts that were never measured together, which is the only way such a number could be produced from this material.

Three limits on the material itself are worth stating rather than leaving to be discovered. The professional-body survey publishes no sampling frame, no response rate and no weighting, so its figures can be quoted but not checked. The review of news coverage searched up to May 2023 and says so, which means it describes a period rather than the present. The NHS England policy quoted here carries its own dates — published 4 November 2024, last updated 6 November 2024 — and a policy can be revised without a page like this one noticing.

One fact about how this site is run applies to this page as much as to any other. A named medical editor has been appointed, and the page names its writer and its checker at the foot. A clinician review line now stands behind those names: the medical editor read this page and a dated signature record was written against it, bound by a hash to the text of its twelve clinical passages, so that rewriting one of them drops the signature and takes the page down until it is signed again. Every clinical-sounding sentence here is either somebody else's, quoted, or a reading of ours. Our first evidence audit has been carried out. Our evidence audit page explains how claims are counted and presents the recorded results. What remains missing is the date on the page: the record holds it, the byline does not print it, and that gap is stated here rather than left for a reader to ask about. Our corrections log has been opened and only grows, and its length is a statement about the age of the log rather than about the accuracy of anything on the site.

What a reader can do with this page is check it. Every quotation above names its publisher and can be found in that publisher's own text, and every peer-reviewed figure carries a journal, a volume and a DOI. Our methodology page sets out the stages a claim passes through before it appears here, and our corrections page is where anything we get wrong will be recorded in the order it was corrected. A sentence here that can be traced to none of these — a named source, a stated measurement of ours, or a reading of ours — should not be here.
