What patients report about Sengel Clinic
Patients report that the clinic provides substandard or failed dental work, with one reviewer stating "my everything is gone" after treatment. Another reviewer describes the dentist as "extremely rude" and alleges they were laughed at when complaining about the poor results. Additionally, a patient claims they travelled from Iran but did not receive the implants they paid for, describing their money as "wasted."
We quote the actual 1–2★ reviews below so you can verify each one yourself, and weigh them against a clinic with a clean record.
Who treats you — and who is accountable
The biggest divide in Turkish dentistry is whether a named specialist treats you start-to-finish, or your case is assigned within a rotating team. At Taki Dent, Prof. Dr. Sadık Taki — a specialist prosthodontist with 17 peer-reviewed publications and Turkish Dental Association membership — personally assesses, treats and follows up every case and stays reachable on WhatsApp, so the person who consents your plan is the one accountable for it. Ask Sengel Clinic for the name of the individual dentist who will perform your surgery, and verify their register entry.
Guarantee & aftercare
Taki Dent's guarantee is written and tiered — a lifetime manufacturer warranty on implant components and a 5–10 year guarantee on crowns and veneers — and for a significant issue it covers a free return trip for corrective treatment, activated by the treating doctor himself. Every patient also receives a serialised implant passport. Get Sengel Clinic's guarantee terms in writing, including who pays for corrective work and return travel.

★1 Thaïs Danthony —
"Completely dissatisfied. Do not recommend. Rip off to this extremely rude dentist who laughs in your face when you tell him the job he did is terrible! Stay away from them. I absolutely do not recommend this rude dentist, a money-making machine, and above all, a botched job. Avoid them at all costs"

How to compare Taki Dent and Sengel Clinic fairly
Sengel Clinic is a verified dental clinic in Sarıyer, İstanbul, listed in our directory from public Google Business data. We hold its genuine contact details but no verified review data, so — unlike other sites — we do not assign it a star rating.
