Teeth Whitening in Thailand for Travellers: Cost, Time & What to Expect

Yes, you can get professional teeth whitening done in Thailand in a single visit. At The Smile Bar in Siam Square, central Bangkok, each whitening session lasts 20 minutes under a UV-free LED light, and packages start at 2,399 THB. We only do teeth whitening, so the whole visit is built around it: 30 to 90 minutes depending on the package, and you’re back to your trip.
How much does teeth whitening cost in Thailand?
Our prices are fixed and published, so you know exactly what you’ll pay before you land. Every package includes a briefing, an oral examination, a shade assessment before and after, the pre-whitening cleaning, and a whitening toothpaste and mouthwash to take home.
| Package | Whitening time | Total visit | Price | Best for |
|---|---|---|---|---|
| Single Whitening | 1 × 20 min | about 30 min | 2,399 THB | Teeth that are already fairly white and need a quick boost |
| Double Whitening | 2 × 20 min | about 60 min | 4,399 THB | Visible stains from coffee, tea or food |
| Triple Whitening (best seller) | 3 × 20 min | about 90 min | 5,799 THB | A first whitening, or if your last one was a long time ago |
Not sure which one to pick? Choose any when you book: we’ll look at your teeth during the briefing and you can upgrade on the spot. Full details are on our prices page.
How does that compare with prices back home?
In-chair whitening at a dental clinic typically costs A$600 to A$1,200 in Australia, £400 to £800 in the UK and US$500 to US$1,200 in the United States. Even our Triple package sits well below the lower end of those ranges. Prices here are in Thai baht, so check today’s exchange rate for the exact difference.
Optional add-ons
Add-ons are chosen on the day of your treatment.
- Nano Protection – 750 THB. A sealing varnish with a triple fluoride formula, applied right after whitening. It protects your result, helps remineralise your teeth and lets you eat and drink normally straight away (more on that below).
- Cleaning & Scaling – from 950 THB. The price depends on the condition of your teeth.
Is it safe to get your teeth whitened in Thailand?
Teeth whitening is safe when it’s done professionally, with the right products and a check of your teeth beforehand. This is how we work:
- Your teeth are checked first: every package starts with an oral examination and a shade assessment.
- A gentle, low-concentration gel: we use Brilliant Smile’s pH-neutral, water-based whitening gel from Sweden.
- No UV, no laser: the gel is activated by a European-made, UV-free LED lamp.
- Short sessions: 20 minutes each, with a break between sessions on Double and Triple packages.
The treatment is designed to keep sensitivity to a minimum. If your teeth are already sensitive, tell the team during the briefing.
Whitening is not recommended if you are pregnant or breastfeeding, wear braces, or are under 18.

How much time should you plan during your trip?
One visit is enough, whatever the package: about 30 minutes for Single, 60 minutes for Double and 90 minutes for Triple, cleaning step and breaks included. The studio is in Siam Square, right next to BTS Siam, so it’s easy to fit in between two plans.
Book before you arrive
Booking online before you fly secures your slot, especially in high season (November to March). You can pick a package now and change it during the briefing.
What to avoid after whitening, and how to skip it
For 72 hours after whitening, your teeth are more likely to pick up new stains. Without protection, you should avoid:
- coffee, tea, red wine and dark sodas;
- strongly coloured or acidic food, such as curries, soy sauce, chilli sauce, tomatoes and citrus;
- smoking.
On holiday in Thailand, three days without curry is a tough ask. That’s what Nano Protection is for: applied right after your session, it lets you eat and drink normally straight away.
What happens on the day
- Briefing and assessment. We explain how the treatment works, check your teeth and record your starting shade on a shade guide.
- Pre-whitening cleaning. You rinse with our whitening mouthwash, then brush with our whitening toothpaste.
- Whitening session. The gel is applied to your teeth and activated by the UV-free LED light for 20 minutes per session. Sit back, listen to music or read.
- Your results. We check your new shade against the same guide. Depending on your stains, teeth usually get 2 to 9 shades lighter, 5 on average. You leave with aftercare advice and your take-home toothpaste and mouthwash.
Have you got ready for your bright smile?
Keeping your results after you fly home
How long your results last depends mostly on what you eat, drink and smoke. The good news: you don’t need to come back to Bangkok to look after them. Every package includes our whitening toothpaste and mouthwash, so you leave with everything you need.
- Use the two-step routine: rinse with 10 ml of the whitening mouthwash first, then brush with the whitening toothpaste.
- Brush twice a day for at least two minutes, and floss once a day.
- Go easy on coffee, tea, red wine and dark sodas, and avoid smoking if you can.
- Stick to the 72-hour rule right after your session, unless you chose Nano Protection.
Running low once you’re home? Our whitening toothpaste and mouthwash are available in our online shop.

Teeth whitening vs other dental work in Thailand
Thailand is a popular destination for all kinds of dental treatment. It helps to know what you’re booking.
The Smile Bar only does teeth whitening, plus an optional cleaning and scaling. We don’t offer implants, crowns, veneers or fillings: for those, you’ll need a general dental clinic or hospital.
Whitening is also one of the easiest treatments to fit into a trip. It takes a single visit, there’s no follow-up appointment, and you can plan it on any day of your stay. One thing to keep in mind: whitening works on natural teeth. Crowns, veneers and fillings keep their original colour.
Frequently asked questions
Is teeth whitening cheaper in Thailand than in Australia or the UK?
Yes, by a wide margin. In-chair whitening typically costs A$600 to A$1,200 in Australia and £400 to £800 in the UK. At The Smile Bar, packages range from 2,399 THB (Single) to 5,799 THB (Triple), with toothpaste and mouthwash included.
Is Thailand a good place for teeth whitening?
Yes, as long as you choose a provider that is transparent about its prices, products and process. At The Smile Bar, prices are published, your teeth are checked before any whitening, and the gel is activated by a UV-free LED light.
Why is teeth whitening cheaper in Thailand?
Mainly because operating costs are lower than in Australia, the UK or the US, and Bangkok’s market is very competitive. The price difference doesn’t come from shorter sessions or skipped steps.
Do I need to book before I arrive?
It’s recommended, especially in high season. You can book online in a couple of minutes. Walk-ins are accepted when a seat is available.
How long do the results last?
It depends on your habits. Coffee, tea, red wine and smoking bring stains back faster. Using the whitening toothpaste and mouthwash included in your package helps your results last longer.
Which payment methods do you accept?
Visa and Mastercard credit and debit cards, PayPal and cash.
Can I eat and drink normally right after whitening?
Only with Nano Protection (750 THB). Without it, avoid coloured or acidic food and drinks, and smoking, for 72 hours.
