Disappointed before?
GC Clinic offers the next step.

A failed dental treatment — wherever it happened — is a serious thing to carry. GC Clinic assesses your situation honestly, with no sales pressure. Dr. Cansu Öztürk reviews your existing treatment and gives you a straight answer — including, where appropriate, "revision at GC Clinic isn't the right choice for you".

We see UK patients regularly with previous treatment from other clinics, here or abroad. We assess everything that has been done — implant, crown, root canal — and provide a written second opinion. No judgement. No high-pressure sales.

What we can do for you

Which complications does GC Clinic treat?

01

Implant complications

Failed osseointegration · infected implant · malpositioned implant → revision, or removal with replacement.

02

Crown / bridge complications

Poorly fitting crown · colour mismatch · fractured porcelain → re-fabrication in e.max or zirconia.

03

Veneers

Over-aggressively prepped · cracked · colour mismatch → revision, or composite bonding as a more conservative alternative.

04

Endodontic complications

Inadequately cleaned canals · recurrent infection → re-treatment under microscope. Dr. Öztürk's specialty.

05

Written second opinion

You don't have to be treated by us. We also provide a written second opinion on your current plan, on its own.

Honesty as default

How do you know it won't go wrong again?

A previous failure makes you — rightly — cautious. Here is what GC Clinic does differently:

  • Brand transparency — every material documented with its lot number. Straumann, Neodent or Nobel Biocare — no in-house brand.
  • Written warranty — per element · 5 years on crowns · 10 years on implant fixtures · 2 years endodontic re-treatment · 1 year soft-tissue grafts.
  • Named clinician — Dr. Cansu Öztürk, endodontist with specialist training, treats you personally. No rotating dentists.
  • 1–2 cases per day — no production line, no rush.
  • "We bring you back" — for covered complications inside the warranty period we organise and pay for the return flight, accommodation and corrective treatment.
Choosing a trustworthy clinic

How to recognise a serious dental clinic in Istanbul.

A checklist — useful even if you don't choose GC Clinic.

  • ✓ Named clinician — one dentist with name, qualification and verifiable references.
  • ✓ A-brand material with lot numbers — no "premium" without a brand name.
  • ✓ Written treatment plan — in English, before you book.
  • ✓ Demonstrable UK aftercare — a protocol you can read, not just a promise.
  • ✓ No rushed intake — you are given time. There is no "book today" pressure.
  • ✓ Independent reviews — Google, Trustpilot, Mumsnet, Reddit — not only the clinic's own site.

Frequently asked

Questions about revision.

Can GC Clinic repair a previously failed implant?

It depends on the situation. Upload your X-ray — we will assess whether revision at GC Clinic is the right choice. Sometimes removal and replacement is required.

Does GC Clinic provide a written second opinion?

Yes. You don't have to be treated by us — a second opinion costs you nothing and commits you to nothing. Free second opinion →

◆ Aftercare · what happens once you fly home

Your treatment doesn't end at the airport.

Every patient leaves GC Clinic with a written warranty, a complete PDF records pack for any UK dentist, and a structured WhatsApp follow-up schedule (24h · 72h · 1 week · 1 month · 3 months · 6 months · 12 months). An annual video review with Dr. Öztürk is standard. If a covered complication occurs within the warranty period, our "we fly you back" clause — written into your treatment agreement, not a marketing line — covers the return flight, hotel and corrective treatment.
