Tooth Whitening

Tooth whitening (or bleaching) is a simple, non-invasive dental treatment used to change the colour of natural tooth enamel and is an ideal way to enhance the beauty of your smile.

Having white teeth has now become the number one aesthetic concern of most patients. Basically there are two main ways to whiten teeth, one is Take-home whitening system and the other is In-chair whitening system.

Take-home whitening is more common in people who prefer the comfort and privacy of their home to achieve the desired results. In-chair whitening consists of high-strength whitening gels that is activated by a high energy light source under the supervision of your dentist. Since tooth whitening only works on natural tooth enamel, it is important to consider replacement of any old fillings, crowns, etc. In-chair whitening involves replacement of any restorations that are being done after bleaching so as to match with the newly bleached teeth.

Reasons for teeth whitening:

Tobacco, coffee, tea, alcohol, food additives, some developmental blemishes, and natural aging , all contribute to the discoloring and yellowing of teeth.

While a Dental Professional clean can remove some staining, Teeth whitening is a cosmetic dental treatment that can provide patients with great results that whiten the colour of teeth which have discoloured over time. Teeth whitening, if maintained correctly, can leave patients with results that last.


Whitening is not suitable for pregnant mothers and also children! And for

  • People with poor enamel or decalcification caused by excessive use of fluorides
  • People with periodontal disease including gingivitis or gums in poor condition

  • People who recently had oral surgery
  • People with decaying teeth or exposed roots
  • People with open cavities

Take-home whitening usually requires two visits. At the first appointment, impressions (moulds) will be made of your teeth to fabricate custom clear plastic trays.

At your second appointment, you will try on the trays for proper fit, and adjustments will be made if necessary. The trays are worn with special whitening solution either twice a day for 30 minutes or overnight for a couple of weeks depending on the degree of staining and desired level of whitening. It is normal to experience tooth sensitivity during the time you are whitening your teeth, but it will subside shortly after you have stopped bleaching.
