Are “Turkey teeth” veneers or crowns? What is really done to your teeth

Often, crowns. What gets called "Turkey teeth" on social media and television is usually a full set of bright, uniform caps across the smile, and many of those are crowns: restorations that cover the whole tooth after it has been ground down on every side. They are frequently advertised as "veneers". The difference matters, because it decides how much of your own healthy tooth is removed, permanently.

This guide explains the difference, what the research says about the risks of preparing healthy teeth, and what to get in writing before you agree to a package of 16 or 20 "veneers".

Veneer or crown: what each one actually is

A veneer is a thin facing bonded to the front of a tooth. The NHS describes veneers as new facings that disguise a discoloured or chipped tooth, and notes that for some veneers the front of the tooth is drilled away a little, but not all veneers need this. The back and sides of the tooth are largely left alone.

A crown is a cap that covers the whole tooth. The NHS page on dental treatments says that to fit a crown, the old tooth has to be shaped so the crown can be fixed onto it. In practice that means reducing the tooth on all sides, which is where the "shaved down" images come from: a row of small tapered pegs waiting for their caps.

Both are legitimate treatments. Crowns are used for teeth that are broken, heavily filled or badly damaged. The concern with "Turkey teeth" is not that crowns exist, but that they are sometimes placed on healthy teeth for a cosmetic result, while the patient believes they are getting veneers.

How much tooth is removed

A laboratory study by Edelhoff and Sorensen (Journal of Prosthetic Dentistry, 2002) measured the tooth structure removed by different preparation designs on model front teeth, ten preparations per design. Veneer preparations removed roughly 3% to 30% of the visible (coronal) tooth by weight. All-ceramic and metal-ceramic crown preparations removed roughly 63% to 72%. The authors concluded that veneer preparations needed about a quarter to a half of the reduction of a conventional crown.

That was a study on resin model teeth, not patients, and real preparations vary with the dentist and the tooth. But the order of magnitude is the point: a crown preparation typically removes most of the visible tooth, and that enamel does not grow back.

Why preparing healthy teeth is irreversible

Once a tooth has been reduced for a crown, it will need a crown, or a replacement for one, for the rest of its life. You cannot change your mind and go back to your natural teeth. Every crown will eventually need replacing, and each replacement happens on a tooth that has already been reduced. Twenty crowns in your twenties or thirties means twenty teeth committed to that cycle. Our guide to how long Turkey teeth last covers what replacement involves.

What the evidence says about nerve damage after crown preparation

Inside each tooth is the pulp, which contains the nerve and blood supply. Grinding a tooth down for a crown can injure it, and a pulp that dies needs root canal treatment or the tooth may be lost.

A systematic review and meta-analysis by Al-Manei and colleagues (BMC Oral Health, 2023) pooled 37 clinical studies of vital (living) teeth that received indirect restorations such as crowns. It estimated the overall incidence of pulp necrosis at about 5%, and of infection or inflammation at the root tip at about 3.6%. The rate was higher for front teeth, for teeth that already had decay or fillings, when temporary crowns stayed on for more than two weeks, and with follow-up beyond ten years. The authors rated the certainty of the evidence as low, and described the incidence as low overall but influenced by many factors.

A prospective study by Kontakiotis and colleagues (International Endodontic Journal, 2015) followed 120 teeth with healthy pulps that were prepared for crowns, testing them before treatment and again before the crown was cemented. Pulp necrosis without symptoms was found in 9% overall: 5% of teeth that were intact beforehand and 13% of teeth that already had decay, fillings or crowns. Those were findings before the final crowns were even fitted.

Put simply: a small but real proportion of healthy teeth prepared for crowns lose their nerve, sometimes without pain. Multiply that across 16 or 20 teeth and the chance that at least one needs root canal treatment at some point is no longer remote. That is arithmetic, not a prediction for your mouth; only a dentist who has examined you can assess your own risk.

What the evidence says about veneers

A systematic review by Alenezi and colleagues (Journal of Clinical Medicine, 2021) pooled 25 clinical studies covering 6,500 porcelain veneers with at least three years of follow-up. It estimated ten-year cumulative survival at 95.5%. Fracture was the most common complication, followed by debonding, both more common in the first years. Need for root canal treatment was an uncommon reason for failure in that review.

That does not make veneers risk-free or right for everyone. Teeth that are badly crowded, heavily filled or worn may not suit them. But it is one reason a dentist may prefer veneers, or less invasive options, where the teeth are healthy.

What about 16 or 20 veneers?

A quote for "16 veneers" or "20 veneers" tells you a number of units, not what will be done to each tooth. Ask why that number: which teeth show when you smile, and which are being included for other reasons. Also ask whether any of them are, in fact, crowns. Our guide to the "Hollywood smile" explains why the same package name can cover very different plans.

What to ask the clinic, in writing

The General Dental Council advises that you should always be assessed by a qualified dentist before being given a treatment plan and cost estimate, and that you should not feel you have to commit on the day. Before paying a deposit, ask for a written, tooth-by-tooth plan that answers:

1. Veneer or crown on each tooth? Ask for the tooth numbers and the restoration type for each one. "Veneer" and "crown" are not interchangeable words.
2. How much tooth will be removed? Ask whether the preparation is on the front surface only, or on all sides, and roughly how deep.
3. Why? For each tooth, what is the clinical reason for that restoration? A healthy tooth being crowned for colour alone deserves a clear explanation.
4. What alternatives were considered? Whitening, orthodontics such as aligners, and composite bonding can change a smile with little or no removal of tooth. Ask why each was ruled out. See our comparison of composite bonding and veneers.
5. What material? Our guide to zirconia and E.max explains what the names mean.
6. What happens if a tooth needs root canal treatment afterwards? Who does it, where, and who pays?
7. Who is doing the work, and what aftercare is provided? The GDC suggests asking who will carry out treatment, whether there is a guarantee on the work and for how long, and what happens if you are unhappy with the result.

Ask for X-rays and photographs taken at the assessment, and keep copies. If you can, show the written plan to a dentist at home before you travel. Our guide to reading a treatment quote covers what a quote should itemise.

Checking the clinic

You can check whether a clinic holds the Ministry of Health's international health tourism authorisation on our register, and read the document behind the entry. The current list of authorised dental facilities is drawn from today's data. If a clinic does not appear, it may be listed under a different legal name or spelling, so search more than one version before drawing conclusions. The authorisation is an administrative permission, not a judgement on the quality of the dentistry.

None of this is advice about your own teeth. Whether a veneer, a crown or something less invasive suits you is a decision for a qualified dentist who has examined you.
