What to Expect from a Teeth Whitening Treatment

An in-office teeth whitening treatment will start with applying a whitening gel to the surface of your teeth. To activate the gel, an LED light will be applied for a specific amount of time, depending on your teeth and desired results.

All teeth are different and can respond differently to whitening treatments. Fillings, crowns, and veneers can’t be whitened during this process, but they can be replaced to match the new shade of your teeth.

What Causes Discolouration?

Stains and discolouration can be categorized into 3 different types: extrinsic, intrinsic, and age-related.


Extrinsic discolouration encompasses stains that affect only the surface of the tooth or the tooth enamel. This typically comes from:

  • Food such as red sauces or chocolate
  • Beverages such as coffee, red wine, and tea
  • Tobacco in the form of cigarettes or chewing tobacco

Intrinsic stains are caused from within the tooth and look more grey in colour. These stains can come from:

  • Certain medications
  • An injury to the tooth
  • Tooth decay
  • Excessive amounts of fluoride
  • Genetics

Aging can cause your enamel to begin to wear down, allowing staining or yellowing to occur. Age-related discolouration can also come from a combination of extrinsic and intrinsic factors.

Maintaining Your Results

After a teeth-whitening treatment, your teeth are still prone to becoming stained or discoloured. By practicing good oral hygiene, you can help maintain your results.
