The name behind the clinic

เลิศ · lert·excellence.

The Thai word เลิศ (lert) means excellence — the finest of its kind, surpassing the ordinary. It is also the surname our founder carries: Dr. Wasit Lertwanich, DDS.

Two meanings, one standard — to do dental work the way it should be done, every time.

Why Choose LERTs

Nine reasons our patients fly back.

The small things that add up to an English-speaking dental clinic in Chiang Mai that patients from 40+ countries return to.

01

Specialist-led care

The dentist who plans your case is the dentist who finishes it. Implants by an implant specialist, orthodontics by an orthodontist, veneers by a cosmetic dentist.

02

Original materials only

Genuine Straumann from Switzerland, Align Technology Invisalign, Philips Zoom — sourced direct from the manufacturer.

03

3D-CT & digital scanning

Cone-beam CT and intraoral scanning on every chair — implants placed with surgical guides, no putty impressions.

04

Digital Smile Design

Preview your new smile on screen and refine it together — before a single tooth is touched.

05

English-speaking team

Specialist dentists and front-desk staff fluent in English. Patients regularly join us from the US, UK, EU and Australia.

06

Transparent fixed pricing

Written treatment plan with itemised costs — fixed before treatment begins. No upsell, no surprises.

07

Calm, private office

A small dental office by design. Most days, you are the only patient in the room at the time of your visit.

08

Old City location

1 Atsadathon Rd, just inside the moat — minutes from Wat Chedi Luang and the Sunday Walking Street.

09

Hospital-grade sterilization

Every instrument runs through ultrasonic cleaning, sealed pouches, and a Class B autoclave at 134°C — the same protocol used in surgical hospitals. Needles, suction tips and gloves are single-use; water lines disinfected daily.

Best dental experience I've ever had. The whole team is warm and professional — Dr. Wasit explained every step of the veneer process clearly and the result is stunning. Worth flying in for.

Came for an Invisalign consult and ended up doing the full treatment plus whitening. The clinic is beautiful, calming, and the iTero scan turnaround was incredibly fast.

Flew in from Berlin for a complete smile makeover — 10 porcelain veneers in 5 days. The 3D smile preview was spot on, the result is exactly what we designed. Highest recommendation.
