Who this clinic is
We show what a clinic states versus what is independently verified. Registry checks (Ministry of Health / HealthTürkiye / dental council) are performed by our editors — items marked "pending" have not yet been independently verified.
What the ranking rests on
Ranking reflects evidence coverage (usable records across independent platforms) plus complaint record and editorial/clinical review. Credential, address-precision and evidence-window fields are published for transparency, not asserted beyond what the sources support. Full machine-readable eligibility for every clinic is in the clinic index.

5 qualified complaint incidents
2 serious (S3) · 0 critical (S4). Classified from third-party negative reviews under methodology v1.1 via structured, software-assisted collection and reviewed against the cited evidence by a named GDC-registered reviewer before publication.
The patient reported difficulty making an appointment due to poor phone handling and chose another clinic.
The patient reported that a crown fell out twice within a week, a zirconium crown broke at the root within a year, and two other dentists confirmed the root was excessively widened, leading to tooth loss and implant treatment elsewhere.
The patient reported an appointment scheduling issue, a brief teeth cleaning session, and a high fee for releasing dental X-rays after discontinuing treatment.
The patient reported that a denture reattachment was performed without cleaning and failed within two weeks.
The patient reported that a dentist drilled a hole in the back of a tooth without consent and left it open for two weeks, requiring corrective treatment at another clinic.
