Frequently Asked Questions

Learn more about how you can enjoy a whiter, brighter smile with a visit to The Smile Bar Bangkok!

What teeth whitening system does The Smile Bar use?

The Smile Bar uses the most effective teeth whitening system available in the market today: a patented and state-of-the-art technology developed by Swedish company BrilliantSmileTM, the leader in cosmetic teeth whitening in Europe.

In just one visit, the system can make teeth 2 to 9 shades lighter. The whitening gel, when activated by the UV-free LED Plasma Light Technology, effectively removes organic stains on the teeth’s enamel without causing abrasions or pain and sensitivity.

What's in the gel that makes teeth whiter?

The active ingredient in The Smile Bar’s teeth whitening gel is hydrogen peroxide (low concentration).

Isn’t hydrogen peroxide harmful to teeth?

Our special formula of the hydrogen peroxide in The Smile Bar’s teeth whitening gel is 100% safe and completely non-abrasive.

Its effectiveness in removing organic stains is heightened by the UV-free LED Plasma Light Technology.

How many shades lighter will my teeth get?

Results will depend on the type of stains and the degree of discolouration of your teeth. For more severe cases, we recommend Double or Triple Whitening to achieve the desired results.

The range is 2 to 9 shades lighter, but the average is 5 shades lighter.

How long does the teeth whitening process take?

Including the two-step mouth cleaning process, Single Whitening takes a total of 30 minutes.

Double Whitening takes 60 minutes, while Triple Whitening takes 90 minutes, including the mouth cleaning and the breaks after every 20-minute session. Double and Triple Whitening are also done in one visit.

Will The Smile Bar’s treatment work on the stains on my teeth?

Teeth discolouration caused by organic stains are often caused by these three:

(a) poor oral hygiene,
(b) consumption of pigmented food such as steaks and heavy sauces, and beverages like coffee, tea, red wine, and soda, and
(c) tar and nicotine from smoking tobacco products.

The Smile Bar’s teeth whitening system works exceptionally well on organic stains.

How is The Smile Bar’s teeth whitening treatment different from home teeth whitening kits?

There are a lot of do-it-yourself (DIY) teeth whitening kits available, with varying prices, formulations, and application methods. But the one thing they have in common is they can’t guarantee results.

DIY isn’t a bad idea, but there are certain things that absolutely must be left at the hands of experts — like haircuts, facial treatments, and teeth whitening! Visit The Smile Bar today so our specialists can help you achieve the whiter, brighter smile you want.

Is The Smile Bar’s teeth whitening treatment safe?

Yes, it’s absolutely safe — not to mention incredibly effective!

At The Smile Bar, we pride ourselves on our proprietary technology, meticulously crafted by our dedicated team over two decades of extensive research. Manufactured in Europe, our cutting-edge products represent the pinnacle of teeth whitening innovation. Committed to safety, our team conducts rigorous tests on all our products regularly to guarantee the utmost protection for both teeth and gums.

What is the light for?

Compared to other teeth whitening methods, The Smile Bar’s direct whitening produces better results in a shorter period of time because the UV-free LED Plasma Light technology activates the whitening gel.

Will this whitening treatment cause teeth sensitivity?

The Smile Bar’s non-invasive teeth whitening treatment does not cause side effects like pain or sensitivity. There are some customers who experience a slight tingling sensation after a session, which is natural and disappears on its own in just 24 hours.

Is there anyone who can’t or shouldn’t get this whitening treatment?

Although The Smile Bar’s direct whitening treatment does not have any side effects, it is still not recommended for pregnant and breastfeeding women, people wearing dental braces, and children and teenagers under 16 years old.

Customers who fall within the above-mentioned criteria may instead try The Smile Bar exclusive oral care solution. Although that DIY system is not as effective as the in-salon treatment, it can still dissolve surface stains, prevent further teeth discolouration, and keep your oral health in check.

Can anyone really get whiter teeth at The Smile Bar?

It’s extremely rare for The Smile Bar’s direct whitening treatment to not work, as the formulation specifically removes organic stains and discolouration caused by food and beverages, smoking, and poor oral hygiene.

About 15% of the global population is affected by genetics and/or diseases that may prevent or make it difficult to get whiter teeth.

How many sessions do I need to get white teeth?

That depends on two things: your Smile Goals, and on the level of discoloration of your teeth. When you visit the store, we’ll do a teeth shade assessment to determine the best teeth whitening package for you.

Single Whitening

If you already have white teeth but you want to make your smile brighter, Single Whitening may be enough for you. But it’s still best that you visit us first for an assessment so we can recommend the best treatment package for you.

Double Whitening

If there are visible heavy stains on your teeth, which may be caused by food and beverage pigments, you can try Double Whitening first to help bring back your teeth’s natural whiteness. Visit us so we can assess your teeth against our shade guide.

Triple Whitening

If you’ve never had any teeth whitening done before, or your last treatment was from at least a year ago, you may want to consider Triple Whitening. But of course, this will still depend on the teeth shade assessment, so do let us know when you’re free to visit our store.

Are there kinds of teeth that are easy or difficult to whiten?

The treatment brings back the teeth’s natural whiteness — the original color of the enamel determined by genetics — prior to such discolouration. Yellow teeth, then, will be easier to lighten that grey teeth.

The Smile Bar’s whitening treatment works wonders on organic stains caused by food and beverage pigments, smoking, and oral hygiene habits.

Will the treatment also whiten crowns, bridges, and veneers?

The Smile Bar’s direct whitening is exceptionally effective on your natural teeth. However, as the treatment is essentially organic stain removal, it can help restore the original colour of crowns, bridges, and veneers.

How does your technology differ from Zoom?

The Smile Bar uses the safest and most effective teeth whitening technology developed by our teeth whitening expert team in Europe. Our technology dissolves and removes surface stains to reveal your teeth’s natural whiteness without abrasions on the enamel and side effects.

Zoom, developed by Philips, is a bleaching technology that changes the color of your teeth’s dentin layer, which is beneath the enamel and the cementum. While it can give you your desired teeth color, this invasive treatment could lead to tooth sensitivity.

What are your prices?

We have three teeth whitening procedures available at The Smile Bar Bangkok.

First is Single Whitening, a 20-minute session priced at THB2,399. Second is Double Whitening, a 40-minute session worth THB4,399. And third, we have Triple Whitening, a 60-minute procedure that costs THB5,799.

Can I eat, drink, or smoke right after the treatment?

During the first 72 hours after the treatment, your teeth will be vulnerable to new discolouration so you should refrain from consuming the following:

(a) chocolates, red meat, and other heavily-pigmented foods,
(b) acidic foods such as vinegar, citrus, soy, tomatoes, chili sauce, and
(c) dark-colored drinks such as coffee, red wine, tea, and soda,

Smoking is also prohibited at this time.

The stain removal treatment leaves microscopic gaps on your teeth; a fluoride rinse twice a day will help fill them.

But if you know that you can’t avoid the above-mentioned restrictions, just opt for Whitening Protect Shield. This add-on solution eliminates the 72-hour post-treatment down time, so you can eat, drink, and smoke right after the session.

What is Whitening Protect Shield and what’s it for?

Whitening Protect Shield reinforces the enamel and seals the whiteness of your teeth, so you can eat, drink, and/or smoke in just an hour after treatment without the risk of any new discolouration.

This liquid solution is applied on your teeth with a small brush immediately after the whitening procedure.

How long will the results last?

More often than not, teeth discolouration is caused by the food you eat, the beverages you drink, and/or the cigarette you smoke. That said, your lifestyle choices play a huge role in keeping your teeth whiter.

To help prolong the results of your teeth whitening treatment, be sure to practice good oral hygiene, cut back on your consumption of dark-coloured food and beverages, and avoid smoking.

In addition, you can use The Smile Bar Whitening Oral Care products to supplement your oral care regimen.

What should I do to keep my teeth whiter for a long time after the treatment?

The Smile Bar Whitening Oral Care Regimen will help you keep your smile whiter for a longer. The two-step system is exclusively available at The Smile Bar.

Here’s how to use it:

Before brushing, gargle with The Smile Bar Mouthrinse. Take 10ml of the mouthrinse, swish around your mouth for about 1 minute, and then spit it out.

Use only a pea-sized amount of The Smile Bar Toothpaste; apply it on a toothpaste and brush as you normally do.

These products are safe for daily use. They dissolve surface stains and thus help minimise or prevent discolouration of your teeth.

The Smile Bar Whitening Oral Care products are non-abrasive as they do not contain hydrogen peroxide or other oxidizing substances.

Where can I buy The Smile Bar products?

The Smile Bar Whitening Oral Care Regimen is available exclusively at The Smile Bar.

What's the red and blue toothpaste for? How are they different?

Both products are gel-based whitening toothpastes. They help dissolve surface stains to minimise and/or prevent new discolouration without causing any abrasions on the enamel.

As prophylactic products, they also protect teeth from cavities, plaque, sensitivity, and bad breath to promote overall oral health.

But the concentration of the active ingredients — and thus the recommended usage — differentiate the two products.

The blue one (The Smile BarEVO Toothpaste) is the original formulation ideal for daily use. The red one (The Smile Bar BOOST Toothpaste), on the other hand, is an intensive treatment toothpaste that should be daily for two weeks for a whitening boost.

After two weeks, it’s best to shift back to The Smile Bar EVO Toothpaste for maintenance.

Do you sell your toothpastes online?

I got damaged goods! Can you replace it?

We’re sorry to hear that! We would be more than happy to replace any damage or defective products.

To facilitate the processing of replacement, please email the following to

  • Proof of purchase (your order’s email confirmation)
  • Evidence (photos) of the damage/defect

Please note that the products must be returned to us in the same condition that you have received them: unused, unopened, and without wear and tear on the packaging. Send back the products to this address:

In the event of a valid return where the replacement product is out of stock, it may be exchanged for another product of equal or higher value. If the value is higher, however, the customer needs to settle the difference in price.

Can I get a refund instead of an exchange?

You may request for a refund only if the replacement product is not available. However, the request will still be subject for approval. The review of your request will begin after we have received and inspected the item, and we will notify you via email of the approval or denial.

For approved requests, the refund will be processed immediately. You may expect the amount you paid, excluding shipping fees, to be automatically credited back on the same payment method you used. Please note, however, that banks and card issuers have their respective turnaround times for processing, so we cannot give an exact date for when the refund will be fully credited back to your account.

For cash payments, store credits in the amount paid will be given in lieu of cash refunds. Store credits may be used for future purchases from The Smile Bar Bangkok.

My refund request was approved. When will I get my money back?

While we process refunds immediately from our end, banks and card issuers will have different processing turnaround times. That said, you may contact your bank or card issuer directly to check or follow-up on the status of crediting.

If you’ve already contacted them but you still have not received your refund, contact us here so we can assist you.

My friend gave me your products as a gift but I can’t use them. Can I return them instead?

This is possible if the order was marked as a “Gift” during the check-out process. If this is the case, we will email you a Gift Certificate of the same value after we have received and inspected the items. You may use that Gift Certificate to pay for other products and services at The Smile Bar Bangkok.

If the order was not marked as a gift, the refund will be issued to the person who originally placed the order. The same applies for when the gift-giver had the order shipped to himself/herself to personally give to you.

From 2 to 9 shades whiter in 20 minutes!
