To achieve a boost to your normal tooth colour with the minimum effort in a short time, during your routine cleaning appointment.

This can be done at your regular 3-6 monthly cleaning appointments to easily maintain a brighter tooth color.
The Take Home Whitening Kit has upper and lower soft trays customised to fit your teeth so the whitening gel contacts each tooth equally for even whitening results and reduces the danger of gel leakage. It needs to be worn daily over 2 weeks.
The WHITEN+ PROFESSIONAL gel is an extra high concentration tooth whitening gel. It deeply penetrates and removes stains over multiple cycles. For safety, we apply it under a light cured gingival barrier that protects the sensitive areas of your gums and teeth surfaces.
Designed for people who want the maximum whiteness their natural teeth can achieve, this multi stage program starts with WHITEN+ PROFESSIONAL to kickstart the deep stain removal, followed by the take home whitening kit to enhance and maintain the whitening effect.

Our WHITEN+ gel contains oxygenating molecules which effectively and gently penetrates and breaks down the stains within the tooth. Thanks to its special formulation and utilising light energy, the oxygen generated will not be dispersed externally (the gel swells), but will remain trapped in the gel and completely conveyed toward the enamel, maximising the whitening action.

Our WHITEN+ program is designed for effective teeth whitening that suits your spectrum of lifestyle and needs. As a safe and healthy treatment, it does not contain desensitizing and remineralizing agents and is compliant with Directive 2011/84/EU.

Teeth become discoloured over time by accumulating stains from what we eat and drink. Stains are classified by external, which are on the surface of the teeth, and internal, which means the coloured compounds actually penetrate into the structure of the teeth.

Sometimes, teeth turn yellow due to the surface of our teeth (the enamel layer) wearing out. This can be due to physical abrasion from harsh particles and heavy brushing, or can be linked to acid erosion. Once thinned, the effect is permanent as enamel layer cannot grow or thicken.


Food and Drink
Coffee, tea and red wine are some major staining culprits. What do they have in common? Intense color pigments called chromogens that attach to the white, outer part of your tooth (enamel).

Tobacco Use
Two chemicals found in tobacco create stubborn stains: Tar and nicotine. Tar is naturally dark. Nicotine is colorless until it’s mixed with oxygen. Then, it turns into a yellowish, surface-staining substance.


Tooth darkening can be a side effect of certain antihistamines, antipsychotics and high blood pressure medications. Young children who are exposed to antibiotics like tetracycline and doxycycline when their teeth are forming (either in the womb or as a baby) may have discoloration of their adult teeth later in life. Chemotherapy and head and neck radiation can also darken teeth.
If you’ve been hit in the mouth or teeth previously, your tooth may change color because it reacts to an injury by laying down more dentin, which is a darker layer under the enamel. Your tooth may also change color due to internal injury, so it is always better to visit your dentist if you suspect any injury.
Below the hard, white outer shell of your teeth (enamel) is a softer area called dentin. Over time, the outer enamel layer gets thinner with brushing and more of the inner layer yellowish dentin shows through.

The inner layer also gets yellower with age, and this also exacerbates the yellow appearance of the teeth.

Ceramic Veneers

A tooth veneer is a thin layer of material that is placed over the surface of your tooth. It is used to change the appearance of either color, shape, size of the tooth.

We use modern dental materials that optimises the bond strength to permanently fix the veneer, while conserving your tooth structure for long lasting preservation of the strength of your tooth.

Does Tooth Whitening Damage Teeth?
As the stain particles are removed from within the tooth, the teeth may become temporarily sensitive which can last for a day or two afterwards. To minimise this, we apply fluoride gel to the teeth after teeth whitening. The sensitivity is temporary and has no lasting effects.
How Long Does My Teeth Remain White After Tooth Whitening?
Teeth Whitening removes the color pigment molecules from the teeth. Teeth are naturally porous and will accumulate stains over time as you eat and do other activities. The rate at which this happens varys from person to person. Avoiding stain causing factors, brushing and regular dental cleaning will slow down this process.
Are Whitening Strips Safe or Effective?
Improper use of over-the-counter whitening gels and strips can cause increased sensitivity and damage to your gums. Also, these over the counter products have a lower concentration of the active ingredient for whitening which makes them less effective than whitening at the dentist. Tooth whitening at the dentist is safer as we take precautions to protect your gum and monitor the progress after each stage of the whitening. For the safety of your teeth and gums, teeth whitening should only be done under the supervision of your dentist.
How Can I Maintain White Teeth?
As teeth are naturally porous, they will pick up stains over time. Regular consumption of coffee, tea or cigarette smoking are the main causes of yellow teeth.
To maintain white teeth, you may choose to use the take home whitening trays periodically, as well as regular dental cleaning with our WHITEN+ program.
If you feel that your teeth turn yellow after whitening, you could opt to do ceramic veneers to add a layer of the whiteness you desire. As ceramic does not stain, this permanently changes the color of your teeth.
How Much Does It Cost for Tooth Whitening in Singapore?
Tooth Whitening cost in Singapore varies depending on the type of whitening. Typically, there are 2 types -
1. in office whitening: this is more expensive as the results are immediate after the session
2. take home whitening with customised upper and lower trays: you have to apply the gel and wear the trays for around 30mins - 2hrs every day for 2 weeks. this is usually cheaper, and also the trays are reusable for next time.
Is Teeth Whitening Painful?
Every person has a different experience with tooth whitening, as it depends on their enamel, the outermost layer of the tooth. The thickness of the enamel layer will affect if the tooth whitening is painful, as well as how effective tooth whitening is for them. People with thicker enamel layer will feel little or no sensitivity, and will have a better result with whiter teeth. If the enamel layer is thinner, it is more likely to have short term sensitivity and less whitening effect.

Frequently Asked Questions About Teeth whitening in Singapore

1. What is teeth whitening?

The basic concept of teeth whitening is the bleaching of the outer layer of teeth to remove stains that have penetrated so that your teeth colour lightens by various shades.

2. What are the different ways to whiten our teeth safely?

There are basically 2 different types:

The Home Whitening method, where your dentist will be doing a scan of your teeth to create a digital mould. These trays are thin and light to wear. You add a small amount of whitening gel to the tray and wear them from two to six hours per day or overnight until the desired whitening is achieved. This process usually takes two weeks. The trays are kept and can be used again for touch-ups.

The second type is the In Office Treatment whereby the teeth are professionally whitened with a higher concentration whitening gel and results can be seen immediately after the treatment.

3. Will teeth whitening damage existing dental restorations?

Over 10 years of clinical use of teeth whitening products containing 10% carbamide peroxide have not shown any damage to existing fillings.  Whitening does not work on existing restorations such as tooth-colored fillings, crowns, bonding, veneers, and bridges. This means that any pre-existing dental work may need to be replaced to match the new tooth shade achieved in the natural teeth if the whitening results in a lighter shade than the old restorations.

4. Do teeth whitening damage my teeth?

Teeth whitening does not cause damage to the structure of the teeth. Studies of teeth whitening products using 10% carbamide perixide showed no effect on the hardness or mineral content of a tooth’s enamel surface.

5. How long can the results of teeth whitening last?

Many factors play into the length of time that teeth whitening lasts. For example, smokers or those who drink beverages that stain teeth, such as red wine or coffee, may not have the same long-lasting effects as those who do not smoke or drink those beverages. Results following teeth whitening can last from 6 months to 2 years, depending on the potency of the treatment. Reducing exposure to staining agents like the ones mentioned above will reduce the rate at which the teeth stain again and prolong the whitening effect.

6. What are the side effects of tooth whitening?

Temporary tooth sensitivity can occur after the teeth whitening process, but it typically subsides after a few days. You can try to avoid cold or sour food or drinks, and use sensitive toothpaste to reduce sensitivity. The intensity and length of time associated with tooth sensitivity after whitening varies by patient.

7. How white will my teeth get?

It’s best to have realistic expectations before undergoing any whitening treatment. Your dentist should be able to explain what you can probably expect. Not all whitening treatments are equally effective on all people, and not all teeth will whiten to the same degree. Teeth whitening can change a tooth’s colour by several shades, meaning teeth that are more stained or discoloured won’t whiten to the same degree as teeth that were whiter originally. It also depends on the structure of your teeth as to how effective the teeth whitening will be.

8. I have a big event – how far in advance should I get whitening?

Teeth whitening has become a popular way to prepare for weddings and other social events where people want to look their best. But because some treatments can take time to be effective, you should make sure you leave enough time before the big day. Home whitening kits using gels can take up to two weeks to achieve results. If you have your teeth whitened professionally by your dentist (sometimes called an “in-chair” treatment), the treatment may be completed in a single appointment of about 1-2hours.

9. Is teeth whitening right for me?

If you have an oral health condition such as tooth decay or gum disease, this should be treated as a priority before arranging a cosmetic treatment. If you haven’t had a cleaning done for a while, this will need to be done before the whitening so as to allow the gel to contact your teeth properly.

Your dentist will let you know what to expect from teeth whitening and if you are able to have teeth whitening done. When you’ve found out what the treatment involves and what the possible side-effects are, you’ll be in a position to judge whether teeth whitening is the right option for you.

10. How fast can I whiten my teeth?

Everyone responds differently to whitening treatments and everyone will whiten at different rates. Stains that are recent are easier to treat than those that have been present for many years. Teeth that are yellow or brown tend to respond better to whitening than teeth that are gray-ish. Younger patients typically whiten more quickly than older patients, but every patient is different.

11. How white should my teeth be?

When whitening, keep in mind that your smile looks most natural when the color of your teeth matches the whites of your eyes. Some people want a Hollywood white smile, which can be whiter than what natural teeth can achieve. In such cases, it may be worthwhile to consider ceramic veneers as an option as they can be made as white as you desire, and they do not change in color over time.
