Denta-Joy Thonglor is one of Bangkok's most credentialed dental clinics: 40+ years established, ISO 9001 certified, ABO Diplomate orthodontist, and Thailand's Invisalign leader with 9,000+ cases. Located in the premium Thonglor expat corridor with confirmed English service and multiple international patients. One documented rude doctor and time management complaints are isolated concerns against an otherwise strong track record.

I switched to using the services at the Thonglor branch. The doctor took very good care of me from the beginning. The staff also took very good care of me. The service was good. The new place looks very good. It's clean, bright, has complete equipment, and has a complete team of doctors.
