Revisions are a clear focus of our practice: a substantial share of our UK patients in 2025 came to us after earlier work that no longer functioned to a standard they were happy with. Typical origins include Hungarian budget chains (generic materials, fit problems), Antalya high-volume clinics (aesthetic mismatch, the so-called “Turkey teeth” regret), earlier UK private work (porcelain fracture, secondary caries, dated metal-ceramic crowns to be replaced) or other Istanbul boutique practices (a clinic move, a gap in aftercare). Our approach: an honest assessment, a targeted partial revision where that is enough, and a full re-make only where it is necessary.


Cobalt-chromium crowns from a Hungarian volume laboratory, slightly bulky at the gumline, plaque trap, chronic gum inflammation. Often acceptable on day one, but a problem 3–5 years later.
→ Replace with e.max or zirconia, typically 4–6 teeth at a time.The classic “Turkey teeth” package: 16–20 full-strength zirconia crowns, often too opaque (“bathroom white”), aesthetically not harmonious, with healthy teeth over-prepared. Patient regrets the decision after 1–2 years.
→ Honest assessment: full re-make in e.max or partial revision (anteriors only).15–25 year old metal-ceramic or gold crowns on posteriors, clinically still sound but no longer wanted aesthetically (a new role, more visible work, or simply personal preference).
→ Targeted swap to zirconia where it is justified by tooth structure.Occlusal chip on a crown (typically from undiagnosed bruxism). The crown needs replacing; at the same time, we check whether other restorations are at risk.
→ New crown plus a night guard plus a review of the neighbouring teeth.A 3- or 5-unit bridge fitted with occlusal mis-positioning — TMJ symptoms, increased clenching, muscle pain since the work was done.
→ Either occlusal adjustment or a new bridge in the correct vertical dimension.Work for long-standing patients whose restorations from the early 2000s are entering a natural replacement window — these cases are reviewed jointly by Dr. Zerrin Engin Bakkal (in clinical practice since 1995, at GC Clinic since 2024) and Dr. G. Cansu Öztürk. Long-standing patients returning to Nişantaşı.
→ New restoration with current technology (CAD/CAM, e.max) · often at a meaningful loyalty rate.Remote · within 4 hours
You send your x-ray and photographs of the restoration in question. Dr. Öztürk reviews and writes back: partial revision, full re-make, or “leave it” — with an indicative plan where treatment is recommended. WhatsApp reply within 30 minutes during business hours.
3–5 nights
In-person check (microscope assessment, rubber dam test), confirmation of the plan, removal of the old restorations, preparation, temporaries fitted. In-house laboratory work begins.
At home 1–2 wks
You wear the temporaries at home (feedback on appearance, bite). For smile-design revisions a mock-up day with DSD can be added.
3–4 nights
Final restorations cemented, bite check, x-ray documentation, warranty certificate with new batch numbers. For small revisions (1–2 crowns) only one trip is needed.
Revisions are more involved than fresh work (removal of the old restoration, assessment of the underlying tooth, adhesive preparation) — hence a small uplift on our standard crown pricing. Hungary vs Istanbul revision: similar headline price, very different finish and aftercare.
