Tooth whitening

Who doesn’t want a radiant smile? A bright smile looks great and projects self-confidence. But certain substances or foods like tobacco, red wine, blackberries or coffee can stain the teeth, causing them to lose their lustre. Teeth also tend to darken with age.

While natural tooth colour varies from pale grey to dark yellow, there’s a treatment that can brighten up your smile: tooth whitening!

Note that teeth whitening can only be performed on the enamel of natural and healthy teeth. Whitening has no effect on veneers, composite fillings, crowns or bridges.

Bleaching is not recommended for pregnant or breastfeeding women. Tobacco use is not recommended during bleaching, since the peroxide contained in the whitening agent increases the risk of cancer due to smoking.

Some patients may experience temporary tooth sensitivity. These effects disappear a few days after the treatment.

Whitening treatment

The professionals at the Lapointe Dental Centres can brighten up your smile!
With proper care and regular follow-up, your  smile will last for years.
This treatment gives you back your radiant smile and is available in two forms:

Clinic treatment

This treatment takes place at your Lapointe Dental Centre. Quick and easy, whitening is completed in a session lasting a little over an hour.
The whitening product is applied on the teeth, then activated with light.
A few subsequent applications of the whitening product at home will maximize the effect of the treatment.

At-home treatment

Whitening can also be done at home. Treatment involves wearing trays previously filled with bleaching gel. This can be done day or night, depending on your lifestyle. Your professional can help you choose the option that suits you best.

Day treatment consists of two 30-minute applications, morning and evening.
Night treatment consists of one application 4 hours minimum before bedtime.
In both cases, the results are brilliant.


Your smile may need an occasional touch-up. The professionals at the Lapointe Dental Centres will touch up your smile as needed to keep it at its best and brightest.

A word about laser whitening

“Laser whitening” is a pretty common topic these days. In fact, it’s a misleading term: laser is confused with the light used to activate the whitening product during the clinical treatment.
