Teeth whitening is a procedure to lighten the natural colour of your teeth without removing any tooth structure. While over-the-counter teeth whitening kits are widely available in Singapore, are they really your best bet in achieving your brightest smile?
Teeth yellow with age and can become stained on the surface through daily exposure to food and drinks such as tea and coffee. Tartar or calculus can also affect the colouration of the teeth. Internal staining is also fairly common. This may have been caused by minute cracks in the teeth or certain antibiotics during teeth development. Check out a list of foods that can stain your teeth here.
Naturally, prior to any treatment, a thorough examination and diagnosis should be performed. We recommend scaling and polishing before teeth whitening is performed.
The success of teeth whitening depends on the cause of discolouration, how long the teeth have been discoloured and other factors. Anyone with teeth which are stained from age, coffee, tea or smoking are ideal candidates for teeth whitening. Patients with healthy, natural, and unfilled teeth often achieve good results. Teeth darkened with extrinsic or surface stains respond better to bleaching than teeth with deep, intrinsic discolouration caused by Fluoride or Tetracycline. These types of stains are unlikely to produce dramatic results. We generally do not recommend bleaching for sensitive or worn teeth; teeth with large fillings or crowns; and teeth affected by gum disease.
In-office Teeth Whitening offers good results. This procedure takes just over an hour. It is more costly. However, the time you can save by having immediate results makes this option appealing. A protective gel layer is placed on your gums adjacent to the teeth and hardened. Then the whitening gel is applied on your teeth.
Teeth Whitening Home Kits take longer to achieve the desired results than in-office bleaching but they are more convenient in terms of time and more cost-effective. Teeth-Whitening Gel (about a third of a tube) is applied on the tray according to the dentist’s instructions. After placing in the mouth, any excess gel which has flowed out should be wiped away gently. Depending on the concentration of the gel, these clear trays are usually worn a couple of hours a day or overnight. It usually takes a couple of weeks before results are noticeable.
For both In-office and Home Kit Whitening, certain food that can cause stains easily (eg. red wine, tomato sauce) have to be avoided for the duration of the whitening.

Current research shows no changes to the tooth surface or tooth structure with the use of 10% bleaching gel. Our experienced and professional dentists will always assess your condition before beginning any treatment, so you can be sure that you are in good hands.
Toothpaste containing Potassium Nitrate or a prescription level of Fluoride can help seal the microscopic tubules (dentin pores) to prevent nerve irritation and sensitivity. There are also professional products available that your dentist can apply to the affected area.
It’s important to have realistic expectations of before and after whitening. Generally, immediately after whitening, the colour will fade very slightly. This may remain stable for approximately 2 years, sometimes longer. However, several factors such as your diet and habits (eg. smoking) can cause staining to occur again. We recommend patients to get touch-ups every 3-6 months to maintain your desired shade.
Why purchase Teeth Whitening Kits from the dentist instead? These teeth whitening kits sold in clinics produce faster and more effective results as they contain a stronger Peroxide-Bleaching agent. Trays and gels from the dentist are also custom-made to fit your teeth exactly. This is important as it protects your gums from the Tooth Whitening Gels.
Hence, we do not recommend over-the-counter kits even though they are cheaper, as they contain only a small concentration of the active ingredient. This significantly reduces the effectiveness of the product. Some also contain mild acids, while others are abrasive. Teeth whitening is a complicated treatment procedure. It should only be carried out by a dentist after a thorough examination and assessment of your teeth and gums. It is very important to follow the instructions issued by your dentist and to ensure that you attend any follow-up appointments recommended.
