How long do Turkey teeth last? Veneers, crowns and implants over time

Porcelain veneers, crowns and implants can last many years, but none of them is permanent. The research reports high survival rates at five and ten years, and it also reports that a large share of restorations need some repair along the way. The practical question for anyone treated in Turkey is less “how long will they last” than “who will look after them when something needs attention, and will that dentist have the information to do it?”

Survival is not the same as trouble-free

Before looking at any number, it helps to know what the studies measure. In most dental research, a restoration has “survived” if it is still in the mouth at the end of follow-up. A veneer that chipped and was polished, a crown that came off and was re-cemented, or an implant crown whose screw loosened and was re-tightened all usually count as survivors. That is why reviews report survival and complications separately, and why a high survival figure can sit alongside a high complication figure.

The figures also describe groups of patients, not you: how your own restorations fare depends on your teeth, gums, bite, habits and the quality of the planning and laboratory work.

Veneers

A 2025 systematic review and meta-analysis of ceramic laminate veneers on front teeth and premolars (Klein, Spitznagel, Zembic, et al., Journal of Esthetic and Restorative Dentistry) included 29 clinical studies. At a mean of about 10.4 years it reported pooled survival of 96.1% for feldspathic porcelain veneers, 93.7% for leucite-reinforced glass-ceramic and 96.8% for lithium disilicate, with no statistically significant difference between materials.

The complication figures in the same review tell a different story. At around ten years, technical complications (such as chipping or fracture) were reported for 41.5% of feldspathic veneers and 29.9% of leucite-reinforced veneers, against 6.1% for lithium disilicate. Zirconia veneers had only 2.6 years of data, so the authors could say nothing about their long-term behaviour. In short: most veneers were still there after a decade, but many had needed attention.

These studies concern thin veneers bonded mainly to enamel. Many “Turkey teeth” cases involve heavier preparation or full crowns, which is a different treatment with a different evidence base; our guide to whether you had veneers or crowns explains the difference.

Crowns

A systematic review of tooth-supported single crowns (Sailer, Makarov, Thoma, Zwahlen and Pjetursson, Dental Materials, 2015) pooled 67 studies with a mean follow-up of at least three years, covering 4,663 metal-ceramic and 9,434 all-ceramic crowns. Estimated five-year survival was 94.7% for metal-ceramic crowns and similar for most all-ceramic types, for example 96.6% for leucite- or lithium-disilicate-reinforced glass ceramics. Zirconia-based crowns were more often lost through fracture of the veneering ceramic and had significantly more loss of retention (the crown coming off) than metal-ceramic crowns, and weaker feldspathic ceramics did worse on back teeth.

Note that the headline figures are five-year estimates. Ten- and fifteen-year data for current crown materials are thinner, and a crown placed today is a restoration you should expect to maintain and, at some point, replace. The tooth under a crown also remains a living part of your mouth: it can decay at the margin, its gum can recede, and it can need root canal treatment later. For more on materials, see zirconia and E.max crowns.

Implants

For implants, it matters whether you mean the implant in the bone or the crown on top. A review of implant-supported single crowns (Jung, Zembic, Pjetursson, Zwahlen and Thoma, Clinical Oral Implants Research, 2012), based on 46 studies with a mean follow-up of at least five years, estimated implant survival at 97.2% after five years and 95.2% after ten. Survival of the crowns themselves was 96.3% at five years and 89.4% at ten. Over five years it estimated 8.8% screw loosening, 4.1% loss of retention and 3.5% fracture of the veneering ceramic, and the authors concluded that technical, biological and aesthetic complications were “frequent”.

A later review focused on ten-year implant survival with contemporary implant systems (Howe, Keys and Richards, Journal of Dentistry, 2019) included 18 prospective studies. The conventional estimate was 96.4%; a sensitivity analysis that allowed for patients lost to follow-up gave 93.2%, and suggested implant loss might be around twice as likely in people aged 65 and over.

The main long-term biological problem is peri-implantitis, an inflammatory condition that destroys bone around an implant. A systematic review of its epidemiology (Derks and Tomasi, Journal of Clinical Periodontology, 2015), covering 11 studies, estimated a weighted mean prevalence of 43% for peri-implant mucositis (inflamed soft tissue) and 22% for peri-implantitis, with wide variation because studies defined the disease differently. Prevalence rose with the time implants had been in function. Spotting it early needs regular examination, which a clinic abroad cannot do from a distance.

What typically goes wrong

• Chipping or fracture of porcelain, on veneers, crowns and implant crowns.
• Debonding or decementation: a veneer or crown comes loose.
• Problems in the tooth underneath: decay at the margin, gum recession exposing the edge, or the need for root canal treatment on a crowned tooth.
• Implant screw loosening or fracture of implant components.
• Peri-implant disease: gum inflammation and bone loss around implants.

Some of this is ordinary wear rather than poor work. A qualified dentist who has examined you is the person to decide what any particular problem needs.

The aftercare problem when your dentist is abroad

Most repairs are small and time-sensitive, and flying back each time is rarely practical, so most maintenance will be done by a dentist at home. The General Dental Council advises patients to speak to their own dentist before travelling, noting that the dentist “will also need to be aware of your plans in case of any later complications”. Its suggested questions to ask a clinic include what aftercare is provided, who pays for extra flights, hotel and remedial work if you are unhappy, and who you can contact for advice after treatment.

A dentist at home can only work efficiently on restorations they understand. Implants are the clearest case: screws, abutments and tools are generally specific to the implant system, so a dentist who does not know which system and components you have may struggle to tighten a loose screw, replace a broken part or make a new crown.

What to ask for in writing, before treatment

• A written treatment summary: which teeth received veneers, crowns or implants, and which teeth were root-treated.
• The material of each restoration (for example, which ceramic) and the cement or bonding system used.
• For every implant: the manufacturer and system, the implant diameter and length, the abutment type and the screw details, ideally with the product labels or lot numbers from the packaging.
• Copies of X-rays and any 3D scans taken before and after treatment, in a format another dentist can open.
• The name and address of the dental laboratory that made the restorations.
• A copy of any warranty and the complaints procedure.

Our guide to medical records before treatment abroad explains how to request and store these, and dental implants in Turkey covers implant planning more broadly.

Warranties: read the conditions

Clinics often offer a warranty measured in years. What matters is the small print. Ask whether it requires regular check-ups, and with whom; whether an appointment with your home dentist counts, and what proof it needs; whether it covers only the restoration or also flights and accommodation; whether it is void if another dentist touches the work; and whether it covers chipping, debonding or peri-implantitis at all. Get the answers in writing before you pay. Our guide to guarantees and insurance for dental work in Turkey goes through this in detail.

If something goes wrong later

See a dentist at home promptly, take your records with you, and keep photographs, dates and receipts. Tell the treating clinic in writing, even if you do not intend to go back. Our aftercare guide covers which symptoms need urgent local care, and how to complain about a clinic in Turkey sets out the formal routes. You can also confirm that the clinic holds a Ministry of Health authorisation on the dental register; if you cannot find it, check under other legal names or spellings before drawing conclusions.
