Teeth Whitening Services in Canada: Cost, Procedure & What to Expect
A bright, confident smile never goes out of style — and for many Canadians, teeth whitening has become one of the most popular cosmetic dental treatments available. Whether it's years of coffee stains, discoloration from aging, or simply the desire for a more radiant look, professional teeth whitening offers a safe and effective solution.
In this guide, we'll walk you through everything you need to know — from how teeth whitening works to the cost, procedure, results, and what to expect afterward.
What Is Teeth Whitening?
Teeth whitening is a cosmetic dental procedure designed to lighten the natural shade of your teeth by removing stains and discoloration. It doesn't change the tooth structure but enhances its brightness, helping you achieve a healthier, more attractive smile.
Over time, teeth can become discolored due to:
Coffee, tea, red wine, and certain foods
Smoking or tobacco use
Poor oral hygiene habits
Aging (natural enamel thinning)
Certain medications
A teeth whitening dentist uses safe bleaching agents, usually hydrogen peroxide or carbamide peroxide, to break down stains and restore a cleaner, whiter appearance.
Types of Teeth Whitening Services
When it comes to teeth whitening services in Canada, you have several options depending on your goals, budget, and how quickly you want to see results.
1. In-Office Professional Whitening
This is the most effective and immediate option.
A dentist-supervised whitening session typically uses advanced systems like Zoom or laser whitening. The dentist applies a concentrated whitening gel to your teeth and activates it using a special light.
Time: Usually completed within 60–90 minutes.
Results: Teeth can appear several shades whiter in a single visit.
Best for: Quick, noticeable results before special occasions.
2. Take-Home Whitening Kits (from Dentists)
Your dentist provides custom-made trays and professional-grade whitening gel for home use.
Time: Worn daily for 30–60 minutes over 1–2 weeks.
Results: Gradual but long-lasting whitening.
Best for: Those who prefer whitening at their own pace under professional guidance.
3. Over-the-Counter Whitening Products
Supermarket or pharmacy products such as whitening strips, LED kits, and whitening toothpaste are also available.
While convenient, these contain lower peroxide concentrations, making them less effective and sometimes inconsistent.
In summary: Professional teeth whitening (in-office or take-home) delivers faster, safer, and more uniform results than DIY products.

Quit smoking or using tobacco.
Brush with a whitening toothpaste and rinse after meals.
Schedule regular dental cleanings.
Your dentist may recommend occasional touch-up treatments or at-home kits to maintain brightness.
Is Teeth Whitening Safe or Painful?
Teeth whitening is safe when done professionally. The whitening agents are carefully applied to prevent gum irritation or enamel damage.
Some people may experience mild sensitivity for a short period, which usually subsides within 24–48 hours. Using toothpaste designed for sensitive teeth before and after treatment can help.
If you have existing cavities or gum issues, your dentist will treat them first before whitening to ensure safety.

While whitening is generally safe, some people should avoid it temporarily or choose alternative options:
Those with untreated cavities, gum disease, or worn enamel
Pregnant or breastfeeding women
People with crowns, veneers, or bonding (as these won't whiten evenly)
Your teeth whitening dentist will help determine the best approach for your dental condition.
