What Published Guidance Describes About Dental Implant Treatment and Care Afterwards

What do published sources describe as the stages of implant treatment?

The NHS describes the object at the centre of this treatment in a single sentence: "To fit an implant, a titanium screw is placed into the jaw bone to support a crown, bridge or denture." Cambridge University Hospitals NHS Foundation Trust divides the work that follows into two named parts, writing that "Implant treatment involves two phases: the surgical phase and the restorative phase." Neither sentence describes a single appointment. The first names a component and what it holds; the second names a sequence with a surgical half and a restorative half. Both documents are United Kingdom publications describing treatment in United Kingdom services, and neither is a description of any clinic in Turkey.

Leeds Teaching Hospitals NHS Trust sets out the surgical step in plain sequence. Its patient leaflet, issued as LN 001941, edition 4 version 1, states: "Injections are used to make your mouth numb. The gum in the area is then lifted to expose the jawbone. A hole is carefully drilled in the bone and the implant is gently screwed in." Cambridge University Hospitals NHS Foundation Trust describes the same component separately in its own patient information, writing that "An implant is a false metal root screwed into the jawbone." Two trusts, writing for their own patients, describe a screw placed into bone. Neither leaflet attaches a duration to that appointment, and neither says how many implants a person might have placed in one visit.

One decision inside the surgical phase is recorded by Leeds Teaching Hospitals NHS Trust as a branch rather than a rule. The leaflet states that "If implant placement is relatively straightforward, a healing cap can be placed on the implant immediately", and the trust gives that route a name of its own, calling it "One Stage Surgery". What the leaflet does not do is say how often each route is taken, or what makes a particular case straightforward. The condition it names, relative straightforwardness, is a judgement made at the time by the person carrying out the work, and the leaflet leaves it as exactly that. Anyone comparing two treatment plans will not find a threshold in this document that settles which route a case falls into.

The restorative phase is where the visible part is made and fitted, and Cambridge University Hospitals NHS Foundation Trust puts a figure on the whole sequence rather than on that phase alone: "The total treatment time is usually at least one year from start to finish." The words doing the work in that sentence are "at least". It is a floor rather than a range, and the trust publishes no ceiling beside it. Set against the same document's division of the work into a surgical and a restorative phase, it describes a course of treatment measured in seasons rather than in days. Whether a particular plan matches that floor is a question for the clinician holding the plan, and no source cited here publishes a figure that would settle it in advance.

On who pays for implant treatment inside the United Kingdom, the NHS is direct: "Implants are usually only available privately and are expensive. Although it's rare, implants are sometimes available on the NHS for patients who cannot wear dentures for certain reasons, such as mouth cancer or an accident." That page carries a review stamp, last reviewed on 8 July 2026 with the next review due on 8 July 2029, so its currency can be checked rather than assumed. The sentence describes a funding route inside one health service. It says nothing about what treatment costs anywhere, including Turkey, and no price appears on this page because no source cited here publishes one.

One source a reader might expect to find behind all this is not there, and its absence was searched for rather than assumed. The National Institute for Health and Care Excellence publishes clinical guidance for England, and NHS England's own policy on self-funded dental treatment lists "NICE guidelines" among the things a request for implant work would be subject to. The institute's own site, accessed on 20 August 2026, was searched for the exact phrase dental implant and returned "No results found". Without quotation marks it returned "Showing 1 to 4 of 4 results for dental implant", none of the four about replacing a tooth. A wider search returned "Showing 1 to 50 of 106 results for dental" with no implant guideline among the titles listed. A control search for the exact phrase oral health returned "Showing 1 to 15 of 51 results", which shows the quoted-phrase syntax works and that the first result was not an artefact of it.

What these stage descriptions cannot be used for is worth stating as plainly as what they contain. Not one of the passages quoted in this section names a country, a clinic or a price, and none of the documents they come from describes how treatment is organised outside the United Kingdom. They describe components and an order: a titanium screw placed in bone, a surgical phase, a restorative phase, and a total course that Cambridge University Hospitals NHS Foundation Trust puts at "at least one year from start to finish". Where these documents give durations at all, the durations are written into the prose rather than set out in a table, which is why every period on this page is quoted in the form its own source used.

What is published about who the treatment is not described for?

NHS Tayside publishes referral criteria for restorative dentistry that include a heading and four items: "Exclusion criteria: Smoking, Uncontrolled Diabetes Mellitus, intravenous bisphosphonate therapy, severe psychoses/neuroses." What that list is, and what it is not, has to be said before anything is read out of it. It is a health board's own criterion for accepting a referral into its own service. It is not a statement that implant treatment cannot be carried out on those patients anywhere, and nothing here should be read that way. Leeds Teaching Hospitals NHS Trust makes the narrower point in one sentence: "Dental implants are not the right option for everyone with missing teeth."

Where that exclusion list comes from is written into the page carrying it. NHS Tayside states: "This summary is based on the Guideline for Selecting Appropriate Patients to Receive Dental Implants: Priorities for the NHS (RCS England 2012)." That matters for how much weight the list can carry. Because the health board names its parent document, a second United Kingdom trust page repeating similar criteria would not be an independent confirmation of them; both would be reading the same college guideline, published in 2012. So the exclusion list is treated here as one documentary line, quoted as a declaration by the body that published it, and anything meant to stand as a general finding is looked for elsewhere.

Peer-reviewed evidence about early implant failure is a different kind of object, and it does not use the word exclusion. A meta-analysis published in Implant Dentistry in 2016 (PMID 26836129, DOI 10.1097/ID.0000000000000386), pooling nine studies covering 18,171 implants, reports that "The main significant risk factors for early implant failures were the smoking habit (odds ratio [OR], 1.7; 95% confidence interval [CI], 1.3, 2.3), implants shorter than 10 mm (OR, 1.6; 95% CI, 1.2, 2.2) and implants placed in the maxilla (OR, 1.3; 95% CI, 1.0, 1.6)." An odds ratio is a measure of association across a pooled sample. It describes how much more often failure was observed in one group than in another; it does not describe what will happen to any individual.

A second and later review reaches the same direction on smoking with a larger sample and a larger effect. Published in the Journal of Dentistry in 2024 (PMID 39393606, DOI 10.1016/j.jdent.2024.105396), it states: "At implant level, a meta-analysis of 21 included cohort studies showed that smoking was associated with increased risk of early dental implant failure compared with non-smoking (odds ratio [OR], 2.59; 95 % confidence interval [CI], 2.08-3.23)." Two independent reviews, eight years and many thousands of implants apart, put smoking on the same side of the line and disagree about how far. The honest way to carry that is as a range, roughly 1.7 (PMID 26836129) to 2.59, rather than as a single number, and that is how it is carried here.

Between a pooled risk estimate and a hospital's own rule there is a step these documents do not take for the reader. Cambridge University Hospitals NHS Foundation Trust writes its own expectation into its patient information: "Smokers have a much greater failure rate and will be expected to stop smoking at least six months before starting implant treatment." That is a condition a named trust applies inside its own service, with a period attached to it. A risk factor identified in a meta-analysis is not the same thing as a contraindication, and a health service's acceptance criterion is not the same thing as either. All three appear in this section because they are three different kinds of statement about one subject.

Two of the three risk factors in the 2016 Implant Dentistry meta-analysis (PMID 26836129) are not about the patient at all, and the distinction matters for a question about who treatment is described for. Alongside smoking, that review reports raised odds for "implants shorter than 10 mm" and for "implants placed in the maxilla" — one a property of the component, the other a property of the site it goes into. Neither describes a category of person. A reader taking these findings into a conversation about their own plan would be asking about the implant and where it is going, not about whether they belong to an excluded group, and the paper supports the first question rather than the second.

None of the sources cited in this section tells a reader whether they personally are suitable for implant treatment, and none is written about clinics outside the United Kingdom. Leeds Teaching Hospitals NHS Trust points at the boundary of its own remit in a single line: "There are national guidelines about who can receive implant treatment within the NHS." That sentence is about eligibility for treatment funded by a health service, which is a different question from clinical suitability, and different again from what a private provider in any country will accept. Suitability is assessed by a clinician who has examined the person in front of them, working from records this site does not hold.

What is published about healing and osseointegration time?

Leeds Teaching Hospitals NHS Trust and Cambridge University Hospitals NHS Foundation Trust both publish a healing period for dental implants, and the two periods do not match. Leeds writes: "Healing of bone takes longer and in most cases, implants are left to integrate, or bond to the bone, for 2 – 6 months before use." Cambridge writes: "The implant is then left to heal in the bone – this usually takes from three to six months but can be longer." Two NHS trusts, writing for their own patients, give two to six months and three to six months. No single figure can honestly be printed here, so both are quoted as their authors wrote them.

How far apart those two ranges actually are is worth stating precisely, because the gap is narrower than it first looks. Both trusts agree on the upper end at six months. They differ only at the lower end, where Leeds Teaching Hospitals NHS Trust writes two and Cambridge University Hospitals NHS Foundation Trust writes three, and Cambridge attaches an open tail to its range with the words "but can be longer". A reader who took six months as the outer figure would be reading both documents correctly; a reader who took two months as a typical figure would be reading one of them and not the other. Neither trust says how its lower bound was arrived at, and neither publishes the distribution behind the range.

One difference between the two documents is typographic rather than clinical, and it changes how the pages behave when they are searched. Leeds Teaching Hospitals NHS Trust prints its period in digits, as "2 – 6 months", while Cambridge University Hospitals NHS Foundation Trust prints its own in words, as "three to six months". Anyone scanning these leaflets for periods by looking for digits would find the Leeds figure and miss the Cambridge one entirely. That is a property of the documents rather than of the treatment, and it is recorded here because it is the mechanism that silently turns a figure that is present into a figure that appears to be absent.

Time before the implant is placed is recorded separately, and Leeds Teaching Hospitals NHS Trust gives it a period of its own: "Tooth extractions are often done 6 – 10 weeks in advance so that the gum has time to heal in the area before implant surgery." Those weeks sit ahead of the two-to-six and three-to-six month integration periods rather than inside them, which is one reason both trusts describe a course of treatment rather than a procedure. The leaflet says extractions are often done that far in advance, not always, and it does not say what proportion of cases involve an extraction at all.

Bone grafting extends the sequence, and Cambridge University Hospitals NHS Foundation Trust states the extension without hedging: "If you require bone grafting, treatment will be prolonged by at least four months." As with the same trust's figure for the whole course, the operative words are "at least". Four months is a floor added to a course the same document already puts at "The total treatment time is usually at least one year from start to finish." The trust does not add those two figures together for the reader, and neither do we, because the document does not say whether the grafting period runs inside the year it names or alongside it.

Whether those two ranges are even measuring the same thing is a fair question, and the wording of both suggests they are. Leeds Teaching Hospitals NHS Trust describes implants "left to integrate, or bond to the bone" and ends the period at the point they are used, writing "before use". Cambridge University Hospitals NHS Foundation Trust describes the implant as "left to heal in the bone" over the same kind of interval. Both are describing the gap between placing the implant and putting it to work, which is why the two figures can be set side by side at all. That reading is ours, drawn from the wording of the two leaflets, and it is offered as a reading rather than as something either trust states.

Reading a healing period out of a hospital leaflet does not produce a schedule for any individual course of treatment. Both ranges cited in this section were written by United Kingdom hospital trusts describing treatment delivered in their own services, and neither document is about implant treatment carried out abroad. Nothing in either leaflet says how long a person should expect to stay in a country where treatment is provided, how many visits a plan requires, or what happens when the two ends of a course are separated by a flight. Those are questions for the treatment plan itself, and the plan is the document that carries the dates.

What does NHS England's policy say about who handles post-treatment issues?

NHS England published a policy on 4 November 2024, under publication reference PRN00784, last updated on 6 November 2024, that answers this in one sentence: "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." The document is titled "Avoidance of doubt: Clinical policy for self-funded dental treatment requiring NHS intervention", and it states its own scope as covering "self-funded dental treatments, including privately funded non-NHS care within and outside of the UK". Dental implant work paid for privately, in the United Kingdom or elsewhere, falls inside that scope.

What that expectation does not carry is a number. The phrase NHS England uses is "within a reasonable timeframe", and the policy attaches no weeks, months or years to it. A reader looking for a period after which the original provider's responsibility ends will not find one in this document. The policy also does not say what happens when that provider is in another country, cannot be reached, or has closed. It states where responsibility is expected to sit first, and it stops there. Anything beyond that would be our inference rather than the policy's text, and it is not offered here.

On what the health service itself will do, the same policy is explicit: "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." It sets out a principle in its own words, that "The NHS will provide the treatment necessary to secure and maintain the patient’s oral health.", and it removes one common worry directly: "Where a patient has received their care previously does not impact on their eligibility for NHS care in the future."

Where a person may present is set out in the same document: "Patients may present directly to primary or secondary dental or medical care settings, or via 111 urgent assessment and referral." A limit follows in the policy's own words: "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." Read together, the policy describes urgent assessment and stabilisation as available, and replacement of privately funded work as not routinely offered. Those are two separate statements in the document, and they are quoted here as two rather than merged into one.

Implants are named in that policy by name, in the part dealing with further elective work. NHS England writes of a patient who "requests further complex elective reconstructive treatment not routinely available as part of NHS-funded dental care (for example, advanced multi-unit fixed appliances and/or implants)", and lists what such a request is subject to: "existing trust-based policies and acceptance criteria", "existing NHS acceptance criteria", "treatment-specific guidelines", "NICE guidelines", and "guidance on the standard of care for NHS funded dental implant treatment". Earlier in the same document it states: "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."

A flow chart published as an appendix to the same policy reduces the whole process to two questions, and both of them are gates rather than entitlements. The first is "Does the patient fit NHS acceptance criteria?", and the policy's description of the chart says of the negative branch: "If not, the process ends." The second, reached only after an acute management plan has been made and pain and infection have been addressed, is "Does the patient have additional needs?", with the same consequence on the negative branch. Whatever else the document does, it does not describe a route that arrives automatically at replacing work someone has paid for elsewhere.

A trust-level document shows what acceptance criteria can look like in one place. The Newcastle upon Tyne Hospitals NHS Foundation Trust, on a page last updated on 20 October 2020, writes that "The Dental Hospital is not normally able to offer treatment for the following:" and then lists three items. They are "Completion of implant treatment commenced elsewhere"; "Making good prosthodontic problems in relation to implant treatment carried out elsewhere"; and "Maintenance if implants and implant restorations provided elsewhere". That is one dental hospital describing its own service in its own words. It is not a national rule, and no source cited here states one.

What did the NHSBSA say about treating a returning patient?

NHS Business Services Authority answers this in a knowledge base article numbered KA-02010, whose title is itself the question: "What can I provide a patient on the NHS who has just recently returned after having dental treatment abroad?" Its first line is the answer: "Dealing with a patient who has been treated abroad is no different to seeing a patient who has previously received care under another contract in England or Wales." The article is written for dentists rather than for patients, which is why it reads as an instruction about contracts rather than as advice. It carries no publication date, so it is cited here by the date it was accessed, 20 August 2026.

What follows in the article is a statement about what must be provided. NHS Business Services Authority writes: "If the patient is accepted in England and the treatment is not Unscheduled Care or if it’s not an Urgent Care Package in Wales, any treatment appropriate to Mandatory Services identified as clinically necessary must be provided subject to the patient or their representative’s consent." Three conditions are stacked in that sentence, acceptance, the category of the treatment, and consent, and the obligation attaches only when all of them hold. The article does not define Mandatory Services inside itself, and it does not say what a patient should do if a practice is not taking on new patients.

The part of the article that bears directly on work paid for elsewhere is its last line, and it is a subtraction rather than an addition: "If the original treatment was not provided by the current contract provider, 'Further treatment within 2 months', 'Free repair / replacement' and 'Regulation 11' replacement appliance will not apply." Three named entitlements are switched off, and the trigger for switching them off is not the country the work was done in. It is the identity of the contract provider. A person whose implant was placed by a different provider in England sits on the same side of that sentence as a person whose implant was placed abroad.

One numbered period appears in that sentence, and where it sits is worth noticing. "Further treatment within 2 months" is written into the article in order to be excluded rather than granted; it is an entitlement that follows treatment by the current contract provider. Beyond it, the article names no country, no treatment type and no implant. Nothing in it is specific to implant work, and nothing in it addresses cost. Reading it as a statement about dental treatment in Turkey specifically would put something into it that is not there: the word abroad appears in the title, and the operative distinction in the text is contractual.

How short this article is deserves recording, because its length is part of what it can be asked to carry. Below its title, the body runs to three sentences: the equivalence with another contract, the conditional obligation to provide mandatory services, and the exclusion of the three named entitlements. All three are quoted in full in this section, so nothing has been left out and nothing has been summarised. A knowledge base entry written for practitioners is not a policy document and does not present itself as one. It answers the operational question a dentist has in the chair, and it leaves the wider questions — cost, redress, and what a provider in another country owes a patient — untouched, because they were never the question it was written to answer.

Our reading of how the two NHS documents fit together is ours, and it is marked as ours. NHS England describes what the health service will do when someone presents with a complication, and the NHS Business Services Authority article describes which repair and replacement entitlements travel with a course of treatment. They answer different questions, and neither of them says that work carried out elsewhere will be redone. A reader who wants the position on a specific case has to take it to a practice, because both documents leave acceptance, clinical necessity and the category of treatment to be determined there.

What does the GDC tell patients to ask before travelling?

The General Dental Council publishes a leaflet for patients called "Going abroad for your dental care", and the part of it a reader can act on before booking anything is a set of questions. Before it reaches them, the leaflet points at the regulator in the destination country. It advises readers to "do some initial research on where your planned treatment will take place", and puts two questions to the country itself: "Does that country have a professional regulatory body? Is it compulsory for dental professionals to be registered with them?" Neither question is about a clinic, a price, or dental implants specifically. Both are about whether a register exists that could be checked at all.

Two concrete lookups are named in the leaflet, and naming them is what separates it from general advice. For regulators elsewhere, it points readers to "health regulators and professional bodies in other countries by visiting www.healthregulation.org". For the United Kingdom it gives a direct instruction: "You can check if a dentist is registered with us by visiting our website, www.gdc-uk.org, and searching the online register or by calling us on 020 7167 6000." A telephone number inside a regulator's own leaflet is the shortest route in this document from a question to an answer, and unlike the questions on its list it does not depend on a provider choosing to reply.

Consultations held in the United Kingdom before travel are addressed separately. The leaflet states: "If your consultation is in the UK, be sure to ask if the dentist is registered with us (the General Dental Council)." About someone who is not registered, the regulator does not hedge, writing that such people "are working illegally and should not be practising in the UK". The General Dental Council also sets a standard for the consultation itself, stating that "You should always be assessed by a qualified dentist before being given a treatment plan and cost estimate." That sentence describes an assessment, a written plan and a cost estimate as three things that either exist or do not.

One passage bears directly on anyone comparing plans for implant work, and it concerns titles rather than procedures. The General Dental Council writes that "In the UK, we hold lists of dentists entitled to use the title specialist" and that "Entry onto these lists is only granted if a dentist meets certain minimum standards of training." It then turns the point outward, suggesting a patient ask about "the same standards of training from the dentist who will be carrying out your treatment abroad". Where a dentist claims a specialist title, the leaflet says it is "important to ask whether they can back this up". The regulator does not say what the answer ought to be.

One suggestion in the leaflet points somewhere this site would not send a reader, and saying so is more useful than passing over it. The General Dental Council writes: "You may also want to talk to other patients who have travelled abroad for dental treatment by visiting online groups and forums." Our evidence audit page defines a first-hand source as one of three things: data we collected and still hold, a primary document, or a published statistic cited to the body that produced it. A forum post is none of the three, which is why nothing here rests on one. The regulator is describing a way of hearing what other people experienced, and that is a different thing from a source a claim can be built on. Both of those can be true at the same time.

Of the items listed under "Some of the questions you may want to ask are", four bear on a course of treatment that ends after a patient has gone home: "How many times have you carried out the procedure I am having? What are the rates of success, complication, readmission and infection?"; "Is the work guaranteed for a certain period of time?"; "If there are complications and I need further treatment, is this included in the initial cost?"; and "Who can I contact for advice after the treatment?" The leaflet's wording differs in small ways from the version of this guidance on the regulator's website, which asks only for a translator while the leaflet asks "Will the dental team speak English? If not, will you provide a translator on the day of the procedure?" What the leaflet never does is answer any of its own questions.

How is this term searched in the UK across three measurement points?

Search volume for the phrase "dental implants turkey" in the United Kingdom was read at three points by one tool, and it rose at each of them: 2,900, then 3,600, then 4,400 monthly searches. Under the rules our methodology page sets out, a measurement is reported with the tool that produced it, the date it was taken and the limits that apply to it, so this section names all three. The tool is Semrush, the readings are for its United Kingdom database, and a capture of the tool's own interface, accessed on 5 August 2026, carries the same 4,400 beside a keyword difficulty of 17 and a cost per click of $5.90.

A second tool returning nothing is itself a result, and it is reported here rather than quietly dropped. SE Ranking, queried for the same United Kingdom market, returned no row at all for the head phrase. What it did return were two derivatives: "dental implants turkey cost" at 10 monthly searches with a difficulty of 5, and "dental implants turkey reviews" at 50 with the same difficulty. For the first of those, the tool that did measure the head phrase reports a figure roughly 72 times larger on the same string in the same market. A third tool, Moz Keyword Explorer, was run against eight terms in this project, and this was not one of them.

Around the head phrase the same capture records a family rather than a single term: 959 variations carrying 30,500 monthly searches between them, of which 81 are phrased as questions and carry 2,300. Global volume for the head phrase is given as 10,400, split across the United Kingdom at 4,400, the United States at 2,400, Türkiye at 880, Canada at 390, Australia at 260, New Zealand at 170, and 1,900 elsewhere. Those seven figures sum to exactly 10,400, which is the one internal check this capture allows, and it passes. The largest single share of the phrase sits in the United Kingdom. That capture is our own keyword measurement record rather than a published source, and every figure in this paragraph is read from it under the rules our methodology page sets out for measurements we make ourselves.

A near-identical phrase was measured separately and rises in the same direction: "turkey dental implants" reads 1,300, then 1,900, then 2,900 across the same three points, at a difficulty of 15. Word order is the only thing separating it from the phrase this page is written for. No separate page was opened for it, and that was deliberate: two pages competing for what is effectively one query is a self-inflicted problem, so the second phrasing is treated as a variant of the first rather than as a target of its own. The decision is recorded here so a reader can see that it was a choice rather than an oversight.

What the three annual readings are not is a continuous series. They are three separate annual figures from one tool, taken for 2022, 2025 and 2026, with no monthly history between them, so the rise from 2,900 to 4,400 is a comparison of three points rather than a trend line drawn through many. Those readings come from our own keyword measurement dataset rather than from a published source, and the years are named here because our methodology page requires a measurement to be reported with the date it was taken. The record holding those three points also carries a twelve-month trend index for the phrase on its own normalised scale, whose low reading is a little over a third of its high one. A yearly figure of 4,400 is therefore an average across a curve rather than a level the phrase holds. The tool labels the difficulty score of 17 as "Easy" in its own interface, and that label is the tool's judgement rather than ours.

Two things about this term were not measured, and they are listed rather than left implicit. No search results page was captured for this exact string, so nothing is claimed about whether an AI-generated summary appears for it; a capture exists for a longer phrase in the same family, and because that is a different string it is not carried across. And the question count quoted here is the tool's own bucket rather than our own question mining, which covered five seed terms and did not include this one. Every figure in this section is a tool's reading of demand for a phrase, not a count of people.

What this page does not do

Nothing on this page ranks a clinic, recommends a dentist, or offers a route to book dental implant treatment anywhere, and the reason is written into our editorial standards page rather than being a matter of tone. We are not a clinic and not an agency, we do not sell treatment, we take no commission, and we accept no payment from any clinic. No price appears here, because none of the sources cited publishes one. Every clinical-sounding sentence on this page is either a quotation from a named publisher or a reading of ours.

A limit specific to this page has to be stated first, because it is the one a reader is most likely to be caught by. Every document cited here is either a United Kingdom publication or a peer-reviewed review of implant outcomes in general. Not one of them describes how implant treatment is regulated, organised or priced in Turkey, and neither of the two meta-analyses reports its results by country. So this page describes what published sources say about implant treatment and about what happens afterwards inside the United Kingdom health system. It does not describe treatment in Turkey, and no sentence here should be read as doing so.

Four freshness debts sit on the sources cited here, and we would rather write them down than let a reader discover them. The NHS Business Services Authority article carries no publication date at all, which is why it is cited by the date it was retrieved. The NHS Tayside referral page carries neither a publication nor a review date. The Newcastle upon Tyne Hospitals NHS Foundation Trust page was last updated on 20 October 2020, the oldest stamp on this page. And the NHS treatments page carries a review cycle running to 8 July 2029, which tells a reader when it is next due to be checked but not whether anything in it has changed since.

Limits on the measurement section matter as much as its figures. One tool returned the head phrase and a second returned nothing for it, so there is no second reading to set against the first, and a single tool's number is a single tool's number. No search results page was captured for the exact string. The country split, the family total and the question bucket all come from one capture taken on one day, and a keyword tool reports modelled demand rather than counted people. Where two tools did overlap on a derivative of this phrase they disagreed by roughly 72 times, which is the best available warning about how firm any of these figures are.

What a reader can do with this page is check it, and that is the only claim being made for it. Every quotation carries the name of the body that published it and the document it came from, so each one can be looked up and read in its own context rather than taken from here. Every figure names the source that produced it and the date it was taken. Our methodology page sets out how a claim has to travel before it appears anywhere on this site, our editorial standards page sets out who writes and how independence is kept, and our corrections page is where anything found to be wrong will be recorded in the order it was corrected. A sentence here that cannot be traced to one of those two kinds of thing should not be here.

How this site is run applies to this page as much as to any other, and it is the reason every clinical statement here is either quoted from a named source or marked as a reading of ours. A named medical editor has been appointed, and the foot of this page names the dentist who wrote it and the editor who checked it. A clinician review line now stands behind those names: this page was read by the medical editor and a dated signature record was written against it, bound by a hash to the text of its sixteen clinical passages, so that rewriting one of them drops the signature. What is still missing is the date on the page itself — the record holds it, the byline does not print it — so a reader sees who checked this page but not when. Our first evidence audit has been carried out. Our evidence audit page explains how claims are counted and presents the recorded results, and our corrections log is published and only grows. Each of those gaps is stated on the page that exists to state it, and each is a reason to check what is written here against the sources named beside it rather than to take it on trust.
