Important — about this score
Please read before drawing conclusions about this clinic.
This score is an automated, opinion-based assessment generated by SmileJet's proprietary AI algorithm from publicly available information — including aggregated third-party reviews, clinic-published materials, and other open-source signals. It is not a statement of verified fact, a professional medical opinion, or an endorsement, and individual experiences may differ.
How the algorithm penalises scores
Our methodology applies score reductions where signals are detected that, in the algorithm's assessment, may indicate: unverifiable or potentially overstated claims about clinical experience or credentials; review patterns the model flags as inconsistent with organic user behaviour; or limited independent corroboration of marketing statements.
These adjustments reflect algorithmic signal-weighting only and do not constitute an allegation of any specific wrongdoing by this clinic or its staff.

This clinic is amazing. Professionalism is at the highest level. Excellent work done by the doctors and staff, top-notch equipment and cleanliness of the premises, the patient is the most important, no waiting lines. I had a chipped tooth, an implant and a dental crown had to be inserted, everything was done superbly. Communication in English was very good and atitude of the staff and Dr. Thongnart was very friendly. The clinic can be compared to the best clinics in the world. Prices are transparent and affordable, for example, the costs for teeth cleaning is 1000 baht... I highly recommend it.
