What are Turkey teeth made of?

Media coinage and semantic drift

The phrase entered UK media usage from approximately 2018 in coverage of celebrity cosmetic-dentistry cases. Over the following years the term broadened to cover almost any cosmetic ceramic work performed in a Turkish clinic and subsequently reviewed by a UK-side dentist or the UK media. The semantic drift means a single label is now applied to four distinct restoration classes — feldspathic porcelain veneers, pressed lithium disilicate veneers, zirconia full-coverage crowns and porcelain-fused-to-metal crowns — each with materially different preparation depths, clinical indications and outcomes. Vista's dental-crown service page sets out which of these is fitted by clinical indication.

BACD position on terminology

The British Academy of Cosmetic Dentistry's 2023 position statement on cosmetic dentistry abroad notes that the conflation of veneer and crown terminology is a consent-process concern.⁵ When the patient and the clinician use the same word for two different restorations, informed consent is harder to evidence. The BACD recommends explicit material and procedure disclosure before treatment — the restoration class (veneer or crown), the ceramic system, the brand, the preparation depth in millimetres, and the lab certificate of authenticity.

Zirconia full-coverage crowns

Zirconia is the most commonly fitted Turkey teeth material. The two principal grades are 3Y-TZP (3 mol% yttria-stabilised tetragonal zirconia polycrystal), with flexural strength typically in the 1,100–1,200 MPa range and high opacity, and 4Y-TZP, in the 900–1,000 MPa range with greater translucency at the cost of some strength.² Both grades are CAD/CAM milled and then sintered, and both are classified under ISO 6872:2015 as ceramic dental materials with defined strength bands. Vista uses monolithic zirconia from established European labs with the certificate of authenticity supplied to the patient.

Lithium disilicate (IPS e.max) veneers

Lithium disilicate, sold under the IPS e.max brand by Ivoclar Vivadent, sits at approximately 400 MPa flexural strength. It is pressed or CAD/CAM milled and offers the aesthetic translucency that monolithic zirconia cannot match in the most translucent shade groups.¹ Pressed e.max veneers are Vista's standard indication-led choice for cosmetic veneer work in the smile zone where the underlying tooth is sound and 0.5–0.7 mm of enamel-confined preparation is appropriate.

Feldspathic porcelain veneers

Feldspathic porcelain — a stacked-and-fired glass ceramic — sits at approximately 70 MPa flexural strength. It is the most enamel-conservative ceramic option and the most aesthetic in skilled hands, but its low strength means the indication is restricted to cases where 0.3–0.5 mm of enamel-confined preparation is sufficient and where occlusal load is low.¹ Feldspathic remains a valid material for thin, minimally invasive aesthetic veneers but is not the right choice for cases requiring fracture resistance under heavier load.

Porcelain-fused-to-metal (PFM) crowns

PFM crowns combine a metal substructure (typically a base-metal or noble-metal alloy) with a porcelain veneering layer. PFM dominated cosmetic crown work in the 1990s and early 2000s but has been displaced for anterior cosmetic indications by zirconia and lithium disilicate. PFM retains a role where occlusal load is high and where the patient cannot accommodate a full-ceramic restoration. In 2026 it is rarely the first-choice material for cosmetic anterior work in Turkey or the UK.

Statistical breakdown

Across the social-media imagery and patient-reported cases reviewed in UK and Turkish dental press, a working estimate is that approximately 70% of “Turkey teeth” depict full-coverage crowns and 30% depict veneers. The ratio is not formally measured by an industry registry, and the figure should be read as an order-of-magnitude estimate rather than an audited percentage. The implication is consistent: a UK patient travelling for “veneers” should confirm in writing whether the proposed restoration is in fact a veneer (0.3–0.7 mm enamel-confined preparation) or a full-coverage crown (1.0–2.0 mm circumferential preparation).

Indication vs preference — the decision-mismatch problem

The decision mismatch arises when a full-coverage crown is fitted because it is faster to prepare and easier to fabricate than an indirect veneer, rather than because the indication supports it. A crown is the right choice where the underlying tooth is heavily restored, root-treated, fractured, or where multiple surfaces require coverage. A veneer is the right choice for cosmetic enhancement of a fundamentally sound tooth in the smile zone. Aschheim's reference text on esthetic dentistry sets out the indication framework in detail.¹ Vista's clinical model is to publish the indication for each proposed restoration in writing before deposit. The Hollywood Smile package documents the indication map for the 16-unit smile zone.

Minimum prep for a veneer

Magne and Belser's bonded-porcelain-restoration framework establishes the conservative preparation principle: 0.3 mm at the cervical, 0.5 mm at mid-facial and 0.7 mm at the incisal for a typical pressed-ceramic veneer, ideally maintained within enamel.¹ A feldspathic veneer can be even more conservative where the indication supports it. The full preparation protocol is set out in the veneer preparation process.

Circumferential prep for a crown

A monolithic zirconia crown requires 1.0–1.5 mm of axial reduction and 1.0–2.0 mm of occlusal reduction, prepared circumferentially. PFM crowns require approximately 1.5–2.0 mm circumferential to accommodate the metal substructure and the veneering porcelain. These preparation depths routinely extend below the dentino-enamel junction into dentin.

What the prep depth means for the pulp

The lifetime pulpal risk is correlated with the proportion of dentin exposed. Burke's 2012 review of bonded ceramic outcomes in the Journal of Dentistry observed that veneers with predominantly enamel-confined margins outperformed those bonded substantially to dentin.⁸ The clinical implication is that a deeper crown preparation carries a higher lifetime risk of pulpitis than a conservative veneer. The full failure-mode discussion is in Turkey teeth gone wrong.

What patients should be told under Principle 3

Principle 3 of the GDC Standards requires informed consent based on the patient understanding what is proposed.³ For Turkey teeth, the minimum disclosure set is: restoration class (veneer vs crown), ceramic system (feldspathic, lithium disilicate, zirconia, PFM), brand (e.g., IPS e.max, Zirkonzahn Prettau), preparation depth in millimetres, expected service life with appropriate hedge, warranty length and conditions, and the originating clinic's HTAC certification status. The same disclosure framework underpins the BACD 2023 position on cosmetic dentistry abroad.⁵

Lab disclosure and material certificate

The certificate of authenticity is the documentary evidence of the ceramic brand and grade. It is typically issued by the partner laboratory and supplied to the patient with the final restoration. Vista's standard practice is to provide the certificate together with the digital scan record and the warranty document at fitting. A clinic that cannot or will not provide the certificate has not evidenced the material specification on which the consent was based — the BACD treats this as a flag for further enquiry before agreeing to treatment.

Veneer indication and material choice

Vista's indication-led model for veneer cases starts with the diagnosis. Where the underlying tooth is sound and the cosmetic objective is shape, shade or alignment improvement in the smile zone, the default material is pressed lithium disilicate (IPS e.max) at 0.5–0.7 mm preparation depth. Where the case requires the most conservative possible enamel reduction and the occlusal load is low, feldspathic porcelain is offered.⁷ Vista's 2026 anchor pricing is from £180 per veneer, with the certificate of authenticity supplied at fitting.

Crown indication and material choice

Where the underlying tooth is heavily restored, root-treated or structurally compromised, a full-coverage crown is the correct restoration. Vista's default crown material is monolithic zirconia (3Y-TZP for posterior load, 4Y-TZP where greater translucency is required in the smile zone). 2026 anchor pricing is from £120 per zirconia crown.
