Teeth Whitening in Mississauga
A dazzling white smile is often one of the first things people notice when meeting someone for the first time. Unfortunately, teeth tend to darken with age, and surface stains from food, drink, or tobacco use often compound the problem. Because of this, it is common for many people to develop a yellowed or tarnished look to their teeth.
Professional in-office teeth whitening treatments can brighten this discolouration and restore the natural beauty of your teeth. There are two main types of teeth whitening treatments used. Depending on your needs, a dentist may use surface whiteners or bleach.
Why Choose Professional Teeth Whitening?
While store-bought whitening kits are widely available, teeth whitening services at your dentist provide faster, safer, and more consistent results. Treatments are customized based on your enamel health, sensitivity, and desired outcome. Under professional supervision, whitening becomes safer for your gums and enamel and results in even whitening with no patchy or uneven shades.
- Noticeable results in less time
- Treatments designed around your unique smile
- Dentist-supervised safety and effectiveness
- Strengthening agents that can protect your enamel
Types of Teeth Whiteners
Teeth whitening treatments typically fall into two main categories: surface whiteners and bleaches. Your dentist will help determine which method is most suitable for your needs.


Surface Whiteners
Surface whiteners are gels or pastes that use abrasives to whiten your teeth. The process is similar to how toothpaste uses tiny abrasive particles to remove plaque from your teeth. The abrasives in surface whiteners are just hard enough to loosen up stains so they can be scrubbed away but not hard enough to cause significant enamel loss or tooth wear.
Bear in mind, however, that these products do not remove tartar buildup from your teeth. You will still need professional dental cleaning to get rid of this and keep your teeth and gums in optimal condition.
Activated charcoal is one of the most popular products being advertised for teeth whitening. Activated charcoal in toothpaste may help remove surface stains on your teeth. Charcoal is mildly abrasive and is also able to absorb surface stains to some degree. However, there is no evidence that it has any effect on stains below a tooth’s enamel or that it has a natural whitening effect.
Bleaches
Peroxide-based bleaches are common teeth whitening treatments and usually produce excellent results. However, these formulations do not work equally well in all cases. Patients with fillings, crowns, root canals, and dark stains on their front teeth may have trouble achieving the shade they want with peroxide-based treatment.

What Can Cause Teeth Discolouration?
- Consumption of coffee, tea, and red wine
- Smoking or tobacco use
- Natural ageing
- Poor oral hygiene
These common causes typically lead to surface staining, which responds well to professional teeth whitening treatments.
However, internal staining caused by medications, dental trauma, or excessive fluoride may not lighten with conventional whitening methods. In such cases, cosmetic options like veneers may be more suitable to achieve your desired smile.

Am I a Good Candidate for Teeth Whitening?
Most people with healthy teeth and gums are suitable candidates for whitening. However, you may not be eligible if:
- You have untreated cavities or gum disease
- You’re pregnant or breastfeeding
- You have crowns, fillings, or veneers on visible front teeth
These restorations don’t respond to bleaching and may result in uneven colour.
We offer complimentary consultations to assess your suitability.
