Dr. Piyamas Luppuyawijit gets repeated praise for cosmetic work — multiple patients say she takes time to explain procedures and delivers natural-looking results rather than the overdone fake aesthetic. Older patients specifically appreciate her approach to veneers and smile design that actually matches their age, which they say is rare in Bangkok.
What ThailandClinics Found
TC VerifiedDr. Piyamas Luppuyawijit gets repeated praise for cosmetic work — multiple patients say she takes time to explain procedures and delivers natural-looking results rather than the overdone fake aesthetic. Older patients specifically appreciate her approach to veneers and smile design that actually matches their age, which they say is rare in Bangkok.
The scaling and cleaning work here is consistently painless according to reviews in multiple languages. Patients mention no bleeding during cleanings and smooth technique, with several saying they've returned year after year because the dentists have genuinely gentle hands.
They handle complex cases — one 18-year loyal patient came back for implants and bridges done in 2008, then returned in 2026 for additional implants and whitening, saying they prefer Bangkok Smile's results over US dental work. The clinic also has Japanese interpreters on staff, which gets mentioned as a real plus for communication.
Worth knowing
Pricing transparency is a genuine problem here. One patient went twice and got different cost quotes each time, with the actual bill not matching the initial estimate. Another had to argue about fairness after paying more than expected, suggesting the clinic doesn't lock in pricing upfront before starting work.
The whitening results are unreliable — one patient did professional Zoom whitening and the teeth reverted to their original shade within days, with before-and-after photos proving it. When they complained, the clinic pushed them to buy an additional take-home kit instead of addressing the failed treatment, which came across as trying to sell more rather than fix the problem.
Booking inflexibility and poor handling of timing issues damaged the experience for at least two patients. One arrived 15 minutes late and was refused a full hour slot despite needing four cavities filled, then left the appointment incomplete and went home without the work done. Another waited 30 minutes past their scheduled time and felt deprioritized after years as a loyal customer.
