Why international patients choose HeySmile

English at every step
Reception, dentists and aftercare messages are in English. Treatment plans and receipts are written in English for insurance claims back home.
Price before you sit down
Every treatment has a fixed price in THB on our price list. You confirm the cost after the check-up, before any work begins.

Check-up, cleaning, fillings and in-clinic whitening are usually done the same day, which suits a short stay in Bangkok.

What international patients say
Google rating 4.9 / 5 from 765+ reviews. A few from patients who travelled to HeySmile from abroad.
★★★★★
"I usually go to the dentist in the United States, and this was my first time seeing a dentist abroad. I'm glad I came because I knew I could get the same level of care I'm used to at home. I really recommend it."
Mr. Paul Chiappetta · USA
★★★★★
"I had my scaling and teeth whitening done at HeySmile in Asoke during my short vacation in Thailand. The staff explained everything they were doing. The scaling and whitening came to a total of 7,190 THB, half of what it would cost in my home country."
Ms. Sarah J. Natalia · Sweden
★★★★★
"They managed to squeeze me and my partner in at the last minute. Way better than back home in the UK. Super clean. Very easy. Will be back next time!"

A dentist near your hotel or condo on Sukhumvit
HeySmile sits at the Asok interchange, so most of central Bangkok is one train ride away.
Dentist near Asok and Terminal 21
We are on Sukhumvit Soi 21, about 5 minutes on foot from Terminal 21, Interchange 21, Sermmit Tower and the Asok BTS / MRT Sukhumvit interchange. Guests at the Sheraton Grande, Westin, Grande Centre Point Terminal 21, Aloft, Solitaire and the serviced apartments on Soi 21 and 23 can walk over without crossing Sukhumvit Road. Same-day cleaning, whitening and check-ups are usually possible.
Dentist near Nana and Phloen Chit
One BTS stop from Nana, two from Phloen Chit: 5 to 10 minutes by BTS or taxi from hotels on Sukhumvit Soi 4, 11, 13 and 15, the Landmark, Rembrandt and Ambassador. Many patients combine a morning appointment with shopping at Central Embassy or Terminal 21 afterwards.
Dentist near Phrom Phong, Thong Lo and Ekkamai
Two to four BTS stops down the Sukhumvit line, 10 to 15 minutes door to door. Popular with expat families living around Soi 24, 26, 39, 49 and 55 (Emporium, EmQuartier, J Avenue): the clinic is open daily until 19:30, so after-work and weekend visits fit around school and office hours.
Dentist near Silom, Sathorn and Ratchada
Take the MRT to Sukhumvit station and walk 5 minutes: Silom is 4 stops, Lumphini 3, Ratchadaphisek 3, with no line change. Office workers in Sathorn and Silom often book the 10:00 or 18:00 slots; from Ratchada and Huai Khwang the trip is under 15 minutes.
Emergency dentist in Bangkok, same day
Toothache, a broken tooth, a lost filling or crown, or swelling while you are travelling: message us on WhatsApp or call 092-749-2829 during opening hours (09:30–19:30 every day) and we will fit you in as early as possible the same day. Pain relief, emergency fillings, extractions and root canal treatment are done in the clinic, with prices from the same fixed list.

Yes. Every dentist at HeySmile consults in English, and the front desk handles WhatsApp, LINE and phone enquiries in English. Written treatment plans and receipts are in English too.
How much does a dentist visit cost in Bangkok?
At HeySmile a check-up with scaling and polishing starts at 900 THB, a filling from 900 THB, in-clinic whitening from 3,590 THB and a crown from 9,000 THB. The full list is on our prices page, and the dentist confirms the exact figure after your check-up.
Can I get an appointment today or tomorrow?

Will my travel or dental insurance accept the receipt?
You receive an itemised receipt and a treatment summary in English with the clinic's licence details, which is what most insurers ask for. Payment is settled at the clinic and you claim back from your insurer.
Where exactly is the clinic and how do I get there?

Yes. Message or call us and we will fit you in as early as possible the same day. Pain relief, emergency fillings, extractions and root canal treatment are all done in the clinic.
What is the difference between the whitening options?
We offer three in-clinic systems: Pola Office+ (3,590 THB, 30–40 minutes), Opalescence Boost (5,990 THB, 45–60 minutes) and Philips Zoom WhiteSpeed (7,900 THB, about 45 minutes). The dentist checks your shade first and recommends the one that suits your teeth. Compare them here.
Do you treat Thai patients and Social Security members?
Yes. Thai Social Security (ประกันสังคม) members can use their annual dental allowance for scaling, fillings and extractions without paying upfront. Details in Thai are on our Thai site.
