Thailand's private dental sector publishes Invisalign or comparable clear aligner treatment across three main hubs: Bangkok, Chiang Mai and Phuket. This list compares ten clinics that state Invisalign, an Invisalign tier such as Diamond or Platinum, or an equivalent US-manufactured clear aligner system on their own websites, alongside what each provider actually says about visit frequency. That detail matters more for this treatment than for most dental work, because a plan built around monthly return trips looks very different for someone living in Thailand than for a two-week visitor.
How did we compare the best Invisalign clinics in Thailand
We compared Invisalign clinics in Thailand by checking official provider websites for clear aligner services, Invisalign status or tier, equivalent aligner systems, dentist or orthodontist information, clinic locations and published details about treatment planning. We gave more weight to clinics that clearly explain scans, monitoring, refinement, retainers and how often patients may need to return.
We also considered whether each clinic is realistic for different types of patients. Clear aligner treatment is easier for residents or long-stay visitors than for short trips, because progress checks, attachments, refinements and retainers may require several visits. This comparison is based on published clinic information, not smile-result claims, discounts or before-and-after galleries.
Ten Invisalign and clear aligner clinics in Thailand


Bangkok International Dental Hospital
Bangkok International Dental Hospital is located on Sukhumvit Soi 2 in Khlong Toei, within walking distance of Ploenchit BTS station. Its Invisalign service page describes clear aligners as a removable, comfortable alternative to fixed braces but does not publish a specific checkup interval or any remote monitoring option. International patients should confirm the exact number of planned in-clinic visits and whether progress can be reviewed by photo between appointments before their first consultation, since the hospital leaves that detail to a direct conversation with the treating dentist.

Thantakit International Dental Center
Thantakit International Dental Center, a family practice on New Petchburi Road dating to 1945, publishes an Invisalign programme led by a dentist named on the site as an Invisalign Platinum Elite Provider who has lectured on the system across Southeast Asia. Its Invisalign page states that patients typically visit the clinic no more often than they would with metal braces and that treatment length runs about the same either way, meaning a short holiday will not usually cover a full case. The page does not mention remote check-ins, so anyone planning separate visits from abroad should ask how far apart Thantakit can realistically space them.

Smile Signature Dental Clinic
Smile Signature Dental Clinic runs multiple Bangkok branches, including one on Sukhumvit Road near Phrom Phong, and states its Invisalign cases are handled only by orthodontist specialists rather than general dentists trained on the system. Its Invisalign procedure page describes monthly in-clinic checkups to review progress and hand over the next set of aligners, a firmer and more frequent cadence than some competitors publish. The group is listed as an Invisalign Diamond Provider and also operates a branch in Patong, Phuket, so a coast-based patient could ask whether follow-up visits can happen there instead of Bangkok.

Chiangmai International Dental Clinic
Chiangmai International Dental Clinic (CIDC) sits on Nimman Road in central Chiang Mai and is presented on its own site as part of the same dental network as Bangkok International Dental Center. Its Invisalign page states that monthly visits may be less frequent than with fixed braces because the dentist can hand over a batch of aligners for the patient to fit at home between scheduled returns, an arrangement worth confirming directly since it changes how many trips a foreign patient needs to plan. Aligner design work is sent to the United States for computerized treatment planning before the trays ship back to Chiang Mai for fitting.

CM Dental Clinic
CM Dental Clinic on Charoenmuang Road in Chiang Mai does not use the Invisalign brand itself but publishes a clear aligner system called Smile TRU, made in the United States from digital scans and shipped back for local fitting. Its orthodontics page states aligners are worn for about two weeks each and total treatment can run from three months to a year depending on the case, shorter than the multi-year estimate the same page gives for fixed braces. The clinic advertises a free consultation and airport pickup service for visiting patients, but does not state how many in-person adjustment visits a Smile TRU case requires, so confirm that schedule before booking flights.

Dental World Clinic
Dental World Clinic in Chiang Mai's Haiya subdistrict lists itself as a Platinum Invisalign Provider and names several of its orthodontists individually as Preferred Invisalign Providers certified by Align Technology in the United States. Its Invisalign fee page breaks pricing down by tray tier, from Invisalign Go at 65,000 baht to Invisalign Comprehensive at 180,000 baht, but does not publish a checkup interval or any option for remote progress reviews. Given that gap, an international patient should ask directly whether the clinic can schedule fewer, longer-spaced visits to fit a limited stay in Chiang Mai.

GrandDent Dental Clinic
GrandDent Dental Clinic on Mahidol Road in Chiang Mai publishes clear aligners under the Invisalign name as one of two orthodontic options alongside traditional braces, describing them as custom trays replaced every few weeks under a dentist's supervision. Its orthodontic treatment page outlines the general consultation-to-retention process but stops short of stating how many in-clinic adjustment visits a typical Invisalign case needs or whether any part of monitoring can happen remotely between trips. Patients coordinating travel from outside Thailand should raise that scheduling question at the initial consultation rather than assume a single visit will be enough.

Phuket Dental Signature
Phuket Dental Signature, a Patong-based clinic operating as a subsidiary of Bangkok International Dental Center, publishes one of the more specific visit schedules in this comparison. Its Invisalign treatments page states that after the aligners are delivered, patients typically return for a checkup only every six to nine weeks, a wider gap than the roughly monthly cadence some Bangkok clinics describe. That stated interval makes the clinic worth a closer look for a patient staying on the island for an extended period rather than a short beach holiday, though the page still does not mention any fully remote monitoring option between visits.

Sea Smile Dental Clinic
Sea Smile Dental Clinic, also trading as Thai Dental Center, sits on Rat-U-Thit 200 Pi Road in Patong, a short walk from Phuket Dental Signature. Its Invisalign page states patients visit the orthodontist about once every six weeks, with total treatment averaging nine to fifteen months across eighteen to thirty aligners, and it publishes a case gallery showing individual treatment times of six to fourteen months. Six weeks between visits is still a real logistical commitment for someone flying in from overseas, and the page does not describe any way to shorten that with remote check-ins.
What to check before booking Invisalign treatment in Thailand
Start by confirming who will plan and supervise your treatment. Clear aligners are not just plastic trays: the result depends on diagnosis, scans, bite assessment, tooth movement planning, attachments, refinements and retention. Ask whether you will be treated by a dentist or orthodontist, how your case will be monitored and what happens if your teeth do not move as expected.
Then check the timeline carefully. Invisalign or similar clear aligner treatment usually requires several visits, not just one appointment during a holiday. You may need scans, fitting, attachment placement, progress checks, refinements and retainers. If you do not live in Thailand, ask how many in-person visits are required and whether remote follow-up is realistic for your case.
Finally, compare the full package, not only the price. Confirm what is included: scans, aligners, attachments, refinements, emergency visits, retainers and post-treatment checks. A cheap offer may be less useful if it does not include follow-up, refinements or a clear plan for what happens after you leave Thailand.
Bangkok International Dental Center (BIDC) operates on Ratchadaphisek Road near the MRT Thailand Cultural Center stop and states that every brace and Invisalign case is handled by a certified orthodontist rather than a general dentist. Its Invisalign page names a Platinum Elite provider on staff with a Chulalongkorn University orthodontics background and more than 700 documented Invisalign cases. The page states that patients generally visit the clinic no more often than they would for metal braces, so a visitor should ask directly how many in-person check-ins their specific case will require before committing to a travel schedule.
