Teeth whitening is an easy and affordable way to enhance your smile!

It removes the stains and yellowish build-up from teeth that makes your smile look older and unattractive. These stains can be in the surface enamel of your teeth or deeper down.

The most effective method of whitening is using custom trays with the reservoir built into the trays for the whitening gel.

Our professional-grade whitening formula can remove:

  • Dark stains and coloration caused by medications

  • Yellowing caused by aging or smoking

  • Stains caused by foods and drinks like wine, coffee, or soy sauce

Have Questions About Teeth Whitening?

Get the answers from our Toronto dentist.

  • Is teeth whitening safe?

    When done with the help of a trained dental professional, yes it is!

    Professional teeth whitening is customized by the strength of the whitening gel according to the needs of your smile and the degree of whiteness desired. There is no danger of damaging tooth enamel like there can be with over-the-counter whiteners.

  • How can I keep my teeth white after my treatment?

    How long your whitening effects last really depends on you. Avoiding staining foods and drinks and not smoking can increase the longevity of your treatment. Because we give you trays and gel to use at home, you can use these for a quick touch-up whenever needed.

  • Does whitening cause tooth sensitivity?

    Whitening can heighten tooth sensitivty temporarily.

    If you do experience any sensitivity to hot or cold foods or drinks, it will disappear within a day or two. Meanwhile, you can use a toothpaste designed for sensitive teeth to help re-mineralize your tooth enamel.
