Dr. Wasit Lertwanich, DDS

Implant & Cosmetic Specialist · Founder of LERTs

The Thai word เลิศ (lert) means excellence — the finest of its kind, surpassing the ordinary. It's also the surname Dr. Wasit carries, and the standard the clinic is named for: two meanings, one standard.

How he works

Planned in 3D, finished with patience.

Every case at LERTs is planned before it begins — in-clinic 3D CBCT for implants, iTero scanning for Invisalign, digital smile design for veneers — using genuine materials sourced direct from the manufacturer.

Same-visit answers — CBCT taken and read here; implant plans typically discussed within about 10 minutes.
Honest triage — if a treatment isn't right for you, he'll say so and show the alternative.
English throughout — specialist dentists and front-desk staff fluent in English; patients regularly join from the US, UK, EU and Australia.
Genuine, traceable materials — implants and aligners traceable to manufacturer batch.

Deep Talk · in his own words

The questions patients really ask.

Beyond prices and timelines — should a cracked tooth come out and be implanted the same day? What actually decides how long surgery takes? Dr. Wasit answers the hard ones directly, the way he would in the chair.

Extract and implant in one surgery — or stage it? How he decides.
Choosing an implant brand: what matters and what's marketing.
Nervous about surgery? What sedation options really feel like.
