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.
7 qualified complaint incidents
6 serious (S3) · 0 critical (S4). Classified from third-party negative reviews under methodology v1.0 (automated draft, pending editorial sign-off).
The patient reported two implants and 20 crowns with cracked front crowns, alignment and biting issues, and gum odor due to poorly sealed crowns.
The patient reported that after treatment, their natural teeth were ground down too thin, causing cracks, and they were left with unnatural-looking teeth and gaps, with the clinic ignoring their concerns.
The patient reported that after receiving 7 implants and a full mouth of zirconium teeth, they experienced holes in the crown, infection, and later discovered at another clinic that implants were placed incorrectly, one was cancelled, and another connected to a natural tooth, leading to a broken crown requiring replacement.
The patient reported that implants placed by Mr. Ozan did not fit properly after being polished by another dentist, and after three years of complaints, the clinic removed the implants and provided dentures, resulting in a total loss of £8000.
The patient reported needing re-treatment for a root canal and being ignored by the clinic despite promises of aftercare.
The patient reported abscess and need for crown removal due to poor fit causing decay, with no response from the dentist and allegations of review manipulation.
The patient reported an implant placed at the wrong angle causing repeated screw breakage, requiring extensive corrective surgery and financial loss.
Red-flag penalty applied: -4 points (capped at −20).

Ratings are Bayesian-adjusted so a handful of five-star reviews cannot outweigh a documented complaint record. Negative reviews are classified as incidents in Complaint & Safety and are not deducted again here.

What the clinic has said
Editorial verification pending. This clinic has not yet been contacted for right of reply on this automated draft.

Any response and its effect on the score will be recorded here and in the change history.
