The overtreatment machine: why high-volume Turkish clinics recommend crowns on teeth that don't need them

The British Dental Association’s 2022 member survey asked 1,000 UK dentists whether they had treated patients for complications arising from overseas dental work. Eighty-six per cent said yes. The most common finding in those consultations was not an infected implant socket or a perforated sinus. It was full-coverage crowns on teeth that had been structurally sound before the patient flew out. Healthy enamel, prepared to a peg, capped in zirconia that will need replacement in 10 to 15 years, on a tooth that will never be fully intact again.

This piece is not about those complications. It is about why they keep arriving in the same pattern, from the same market, year after year. The answer is not that Turkish dentists are incompetent. The answer is that a specific business model, applied at scale, produces this outcome as a feature rather than a failure. Understanding the model is the prerequisite for identifying which clinics are not running it.

The pattern from the consulting room

I have retreated enough of these cases to find the clinical picture immediately recognisable. A patient in their late twenties or thirties presents after a full-arch cosmetic procedure in Antalya or Istanbul. She wanted whiter, more even teeth. She had healthy, intact enamel with minor colour variation or mild crowding that, in my clinical assessment, would have been well-served by bleaching, composite bonding, or a small number of conservative veneers. Instead, 18 to 22 teeth were prepared for full-coverage zirconia crowns in a three-day visit. The preps are aggressive: cusps reduced, interproximal contacts destroyed, the axial walls cut to a taper that maximises retention height and nothing else. Two to three years later, she is in my surgery because one crown has debonded, or because she has been waking at 3am with thermal sensitivity in two of the upper anteriors, or because her local dentist’s radiograph shows periapical change around a tooth whose nerve, stressed by the preparation, has quietly died.

The clinical damage is real and often irreversible. The tooth that has been aggressively prepared and crowned can be root-canal-treated if the pulp fails. The crown can be recemented or replaced. But the intact tooth structure that was removed to make the crown possible is gone. There is no clinical pathway back to what the tooth was before the appointment.

The question I find myself asking in these cases is not “what went wrong?” Something going wrong implies an accident. The question is “why was this treatment recommended in the first place?”

The economics of cosmetic crowns

To understand why, you have to follow the money backwards through the clinical decision.

A cosmetic dental clinic in Antalya or Istanbul is running a service-volume business. Its revenue comes from the number of procedures it performs per chair per day. Its cost structure is fixed: rent, staff, equipment depreciation. Its profit margin expands when treatment output rises and contracts when chair time is idle or occupied by low-revenue procedures.

A full-arch crown preparation on 18 to 22 teeth is a high-revenue procedure that can be completed, in the hands of an experienced operator, in two to three chair hours per arch. A full-arch crown preparation is also teachable, repeatable, and does not require the kind of case-by-case decision-making that slower, more conservative procedures demand. Every patient gets approximately the same treatment. The prep guide is the same. The lab prescription is the same. The fitting appointment is the same.

Now compare this with the conservative alternatives.

Composite bonding on 6 to 8 front teeth for a patient with mild colour variation and minor chips requires careful freehand sculpting, shade matching, a clinician who can work within the existing occlusion rather than reconstruct it, and a patient who is willing to come back in six months for any adjustment. Revenue per patient: a fraction of a full-arch crown case. Skill threshold: higher.

Conservative veneers on 8 to 10 teeth require preparation depths controlled to stay within enamel, tight margin designs, a laboratory that can fabricate thin feldspathic porcelain without overbuilding, and a clinician experienced enough to cement them without inducing pulp stress or colour mismatch. Revenue per patient: comparable to a partial crown case, lower than full arch. Chair time: more, because precision is slower than throughput.

Bleaching, in a patient whose only complaint is tooth colour, costs the clinic almost nothing to deliver and charges the patient almost nothing compared to a crown case. It is the least profitable procedure available and the one most likely to satisfy a cosmetic patient who has healthy teeth.

The hierarchy of revenue per chair-hour, from highest to lowest, runs in exactly the opposite direction from the hierarchy of tissue conservation. Crowns generate more revenue than veneers, which generate more revenue than composite bonding, which generates more revenue than bleaching. And the tissue destruction required runs in the same direction as the revenue. The most profitable procedure is also the most destructive one.

This is not a Turkish phenomenon. The same incentive structure operates in every market where high-volume cosmetic dentistry is practiced. But the Turkish high-volume dental tourism model makes the incentive particularly acute, because the per-chair-day volume must cover the overhead of operating an international-facing clinic with coordinators, hotel arrangements, airport transfers, and a marketing spend large enough to fill that volume with foreign patients.

What throughput pressure does to individual dentists

The revenue model operates at the clinic level. It transmits downward to the individual clinician through the structures most large dental businesses use to manage productivity: daily targets, volume-based remuneration, and case-mix expectations.

A dentist employed in a high-volume cosmetic tourist clinic in Antalya is typically salaried or on a revenue-share arrangement that rewards output. If the daily expectation is to complete two to three full-arch cosmetic cases, the clinician who spends two hours in a consultation recommending composite bonding for a patient the coordinator pre-assessed as a full-arch crown candidate is not meeting the target. The consultation is the bottleneck. The crown prep is the throughput.

The treatment plan, in most of the cases I see arriving back in Australian or UK consulting rooms, was agreed before the patient left home. It was quoted by a patient coordinator (not a clinician) based on photographs submitted through a website or an app. The clinician the patient eventually sees in Turkey is executing a plan they were not involved in designing, on a patient they are meeting for the first time, in a chair-time window that does not accommodate the kind of history-taking and examination that would identify reasons to deviate from the plan.

This is the structure that produces overtreatment even when individual dentists are competent and well-intentioned. The system does not require negligent clinicians. It requires a normal human response to throughput pressure applied over time.

The British Dental Journal’s 2025 review of returning dental-tourism patients describes the clinical aftermath: five teeth tender to percussion in a single returnee, periapical pathology across multiple crown preparations, and the medico-legal complexity of attempting restorative remediation on crowns whose material specification, cement type, and preparation depth are unknown because no clinical records accompanied the patient home. The individual dentist who placed those crowns is not named. The system that produced the case is invisible in the report. But the pattern is the one I am describing here.

Why healthy teeth are the ideal candidate

The other thing the throughput model produces, less obviously, is a selection effect: the patients most likely to be overtreated are the ones who needed it least.

A patient who arrives in Antalya with genuinely complex dental problems, multiple failing restorations, active periodontal disease, or significant missing teeth is a complicated case. She requires proper workup: periodontal charting, full periapical radiograph series, a treatment sequence that addresses disease before it addresses aesthetics, and possibly a referral component for specialist input. She is not a good candidate for a three-day turnaround. A clinic that takes her on anyway and rushes to the cosmetic phase is taking on clinical risk the throughput model is not designed to manage.

The patient most suited to the throughput model is the one who doesn’t need extensive treatment. She has mild cosmetic concerns: slight colour variation, minor tooth wear, one or two chips. Her teeth are healthy. Her bone support is good. Her gums are pink and not inflamed. The workup is minimal because there is almost nothing to work up. She can be in and out in three days because the biology is on her side.

This patient is also the one who should, under any treatment-planning philosophy oriented toward the patient’s long-term interests, receive the most conservative intervention available. Bleaching. Composite bonding. No intervention at all. The tissue-conservation hierarchy, which runs from no treatment through bleaching, bonding, veneers, and only then crowns, places her firmly at the no-intervention or bleaching end of the spectrum.

Instead, she is the ideal candidate for a full-arch crown case, precisely because her health status makes the procedure safe enough for a rapid turnaround. Her healthy teeth are what makes aggressive preparation possible. The clinic does not profit from her health. It profits from replacing it.

The veneers, crowns, and composite bonding decision piece sets out the tissue-conservation hierarchy in clinical detail and explains when each intervention is correctly indicated. The gap between what that hierarchy recommends and what a high-volume cosmetic clinic recommends for the same patient is the gap this piece is describing.

How to recognise a clinic that doesn’t run this model

The throughput model is not the only model operating in Turkey. There are Turkish clinics running genuine specialist-led practices with proper case-selection discipline, conservative treatment philosophies, and outcome data they are willing to share. The Turkey teeth analysis makes this point directly: the geography is incidental, the model is not.

The question is how to identify whether the clinic you are considering is running the throughput model or something else. Three markers are reliable.

The consultation structure. A clinic whose initial assessment is done by a patient coordinator rather than a clinician, whose treatment plan is agreed in principle before you attend in person, and whose quote arrives within 24 hours of your first contact is a throughput clinic. A clinician-led assessment requires the clinician to see you, examine you, take radiographs, and make a recommendation based on findings. That process takes time. The quote that arrives before any of that has happened is a target, not a clinical plan.

The conservative option conversation. Ask directly: “What would happen if I had composite bonding instead of crowns?” A clinic whose treatment-planning culture is patient-need-driven will be able to answer this. It will explain when bonding is suitable and when it isn’t, what its limitations are, what the long-term maintenance looks like, and whether it applies to your case. A throughput clinic will either not offer composite bonding at all, or will explain why it isn’t suitable for you without a clinical argument you can evaluate. “You need crowns because your teeth are too discoloured” is not a clinical argument. It is a sales script.

The case-rejection rate. This one is harder to verify from the outside, but you can ask directly: “Are there patients you decline to treat?” A clinic that genuinely exercises case selection will be able to describe the categories of patient it refers elsewhere: patients with active periodontal disease who need treatment before any cosmetic work; patients with bite problems that need orthodontic management; patients whose cosmetic concerns would be better addressed conservatively. A clinic that accepts every patient, for every procedure, within the same three-to-five-day package, has no meaningful case-selection discipline.

The dental tourism trust gap makes the structural argument for why these questions are hard to answer from a website or a social media page, and what verification is actually possible before you book.

The patient who should be most sceptical

Not every patient who considers dental tourism in Turkey is equally exposed to the throughput model.

The patient most at risk is the one the throughput model most wants: healthy or mildly imperfect teeth, a cosmetic complaint, no complex medical history, and enough budget to pay for a full-arch package. She is the patient for whom conservative treatment is clinically correct and aggressive treatment is commercially optimal. She is also the patient the marketing most often reaches: reality TV viewers in their twenties and thirties who have seen before-and-after photographs on TikTok and want the same result.

The cross-border dental liability review documents what happens when this patient returns with complications and discovers she has no regulatory protection, no warranty she can enforce, and a local health system that will not fund corrective treatment for cosmetic procedures performed privately overseas.

The patient with genuinely bad teeth, by contrast, is at lower risk of being overtreated, though she faces a different set of risks that the zirconia full-arch analysis and the peri-implantitis cascade piece address. She needs complex work, and the throughput model may still execute it badly. But it is at least executing work she actually needs.

The saddest cases I see are the ones in the middle: the patient who had two or three teeth that genuinely needed crowns, and flew home with twenty-two.

What would change this assessment

The throughput model’s treatment-planning pattern would revise in my clinical assessment if any of the following appeared.

A peer-reviewed audit from a Turkish prosthodontic programme, examining treatment plans for international cosmetic patients and comparing the recommended treatment against an independent specialist’s assessment of the clinical indication, would be the most direct evidence. If that audit found that full-arch crown recommendations were clinically justified at a rate comparable to domestic specialist practice, the economic argument I am making here would need to be reconsidered.

A major Turkish dental tourism platform publishing, voluntarily and publicly, its rate of conservative-to-invasive procedure referral within its patient cohort would be similarly informative.

Neither currently exists. The 2025 British Dental Journal media analysis of 131 UK newspaper articles on dental tourism found that coverage focused heavily on individual harm cases and celebrity endorsement, with minimal attention to the structural economic drivers this piece describes. The structural analysis is the part the press is not doing. This publication’s job is to do it.
