Teeth Whitening in Bangkok
from ฿3,590

Yes, of course. We offer professional in-office whitening with visible results in just one visit (30-60 minutes). Teeth cleaning is not part of the whitening package: if your teeth need scaling and polishing first, it is a separate treatment (900–1,500 THB) that can be done in the same visit.

Teeth whitening at HeySmile Dental Clinic is designed to be safe and comfortable. We use clinically approved technology and premium-grade products to minimize sensitivity while achieving effective, visible results.

All treatments are performed under the supervision of experienced dental specialists to ensure optimal care throughout the process.

The longevity of your teeth whitening results will largely depend on your daily oral hygiene practices and your consumption of stain-causing substances such as coffee, tea, red wine, or tobacco.

However, by minimizing intake of these highly stainable drinks and diligently following the recommended oral care products from HeySmile Dental Clinic, you can enjoy the benefits of your teeth whitening for years to come.

Done in one visit of about 30–60 minutes. Gentle whitening process. Dentist assessment and VITA shade check included. Supervised by specialist dentists.

At HeySmile Dental Clinic in-office teeth whitening costs 3,590 THB (Pola Office+), 5,990 THB (Opalescence Boost) or 7,900 THB (Philips Zoom WhiteSpeed), roughly US$105–230. Every package includes a dentist assessment and a VITA shade check before and after treatment, so the price you see is the price you pay.

Pola Office+ (a quick in-clinic session, about 30–40 minutes) suits a quick touch-up. Opalescence Boost (a professional in-clinic whitening treatment, 45–60 minutes) is our most requested option for deeper stains. Philips Zoom WhiteSpeed uses LED light activation in about 45 minutes. Your dentist recommends one after checking your current shade, enamel condition and any history of sensitivity.

Whitening gel only lightens natural tooth enamel. Crowns, veneers and tooth-coloured fillings keep their existing colour, so the dentist checks for visible restorations first and may suggest replacing them after whitening if the shade no longer matches.

No. Zoom WhiteSpeed uses a blue LED lamp to activate the whitening gel; it is not a laser. All three systems at HeySmile are professional whitening gels applied and monitored by a dentist.

For the first 48 hours avoid coffee, tea, red wine, curry, soy sauce, cola and smoking, because freshly whitened enamel picks up stains more easily. Water and light-coloured foods such as rice, chicken, fish and bananas are fine.

Book your visit two or three days before you fly home so any temporary sensitivity has settled. The whitening itself takes 30–60 minutes; if you also want scaling and polishing, allow about 90 minutes. The clinic is a 5-minute walk from BTS Asok and MRT Sukhumvit, near Terminal 21, and is open daily 9:30–19:30.

Send us a message on WhatsApp (+66 92 749 2829) or LINE @heysmile with your preferred date and time, and tell us which system you are interested in. We confirm the appointment and the price before you arrive, and payment is settled at the clinic after treatment.

Whitening is not recommended for pregnant or nursing women, patients under 18, people currently wearing braces, or anyone with untreated cavities or gum disease. The dentist checks these points during the assessment that is included in every package.

Yes. “Teeth bleaching” and “teeth whitening” are two names for the same professional whitening-gel treatment; dentists tend to say whitening and many patients from the UK, Australia and Europe say bleaching. At HeySmile in Bangkok you can have it done in the clinic in one 30 to 60 minute visit (Pola Office+ 3,590 THB, Opalescence Boost 5,990 THB or Philips Zoom WhiteSpeed 7,900 THB) or with custom take-home trays for 4,990 THB.
