Why Choose TDH Dental at Icon Siam
TDH Dental carries a set of credentials that set it apart across Thailand's competitive dental market. The TDH orthodontist team holds Thailand's only Invisalign Red Diamond Provider status as of 2024, a designation awarded by Align Technology only to providers treating more than 1,000 Invisalign cases per year across moderate to highly complex presentations. This places TDH among a small number of practices globally recognized at that tier. Beyond orthodontics, TDH has built a reputation for cosmetic smile design backed by celebrity and influencer endorsements across Thailand, and for treating international patients who fly in specifically for veneer and implant work. The clinic uses an iTero Element intraoral scanner for digital treatment planning and operates under protocols certified to ISO 9001:2015 quality management standards.
