What professional whitening is
Brighter teeth, done right
Staining builds up over the years from coffee, tea, red wine, tobacco, and simply getting older. Brushing alone will not shift it. Professional whitening uses a dentist grade gel that breaks down those stains far more effectively than any drugstore strip.
The real difference with whitening at a dental clinic is not just strength. It is safety. At Walk In Dental Clinic on Yonge Street, Dr. Farah Karimi checks your teeth and gums first, protects your enamel and gumline, and adjusts the gel to keep sensitivity low.
You get an even, predictable result instead of the patchy spots and wasted money that home kits so often cause. We whiten teeth for patients across Toronto, North York, Richmond Hill, and Vaughan.

Why patients choose us
Why professional whitening beats drugstore kits
Bigger, even results
Professional gel reaches stains that strips cannot, and lifts several shades evenly. No patchy spots, no missed edges.
Safe and supervised
We protect your gums and enamel and manage sensitivity, so you whiten without the burns and irritation home kits risk.
Fast or flexible
Choose a one hour in office session, or custom take home trays to whiten at your own pace. Whichever fits your life.
Is Professional Whitening Right for You?
- Whitening May Help With
- Coffee, tea and red wine stains
- Tobacco related surface staining
- Natural darkening that occurs over time
- Healthy natural teeth that are suitable for treatment
- Discuss These First
- Cavities, gum inflammation or unexplained pain
- Existing tooth sensitivity or receding gums
- Crowns, veneers, fillings, bonding or dentures
- Heavy buildup that may require cleaning first
When whitening cannot correct colour or shape, the dentist may discuss options such as dental bonding or dental veneers.
The process
How in office whitening works
Quick assessment
We check your teeth and gums, note your starting shade, and confirm whitening is right for you. Natural teeth whiten well. Crowns and veneers will not change colour, so we tell you that up front.
A few minutes
Protect and prepare
We place a barrier to shield your gums, then apply the professional whitening gel. This is the step no home kit does for you.
Comfort first
Whiten
The gel is activated and works in short cycles while you relax in the chair. Years of staining lift away.
About 1 hour
Reveal and protect
We rinse, apply a desensitiser, and show you your new shade. You leave with simple tips to keep your smile bright for longer.

Cost
How much does teeth whitening cost in Toronto?
Professional teeth whitening in Toronto generally costs between $250 and $450. Where you land depends on whether you choose a single in office session or custom take home trays, and on how much staining we are lifting. You get the exact price up front, before we start.
For comparison, drugstore strips and LED kits run $30 to $150, but they use far weaker gel, take weeks, and often give uneven results that cost more to correct later.
Whitening is a cosmetic treatment, so most insurance plans and CDCP do not cover it. If you have cosmetic coverage on your plan we will bill it directly. We also offer flexible payment options, and we will check what your plan includes before you commit to anything.

Teeth whitening questions people ask
How much does teeth whitening cost in Toronto?
Professional whitening runs $250 to $450, depending on whether you choose an in office session or custom take home trays. You get the exact price before we begin, with no surprises.
How white will my teeth get?
Most patients lighten by several shades, often noticeably after a single in office visit. Your result depends on your starting shade and the kind of staining, which we check first so your expectations are realistic.
Is professional teeth whitening safe?
Yes. Under a dentist’s supervision, whitening is safe for your enamel. We examine your teeth and gums first and place a protective barrier on your gumline, which no drugstore kit can do.
Does whitening hurt or cause sensitivity?
Some people feel mild sensitivity for a day or two. We apply a desensitiser and can adjust the gel strength to keep you comfortable. This is much gentler than guessing with over the counter products.
How long do the results last?
With good habits and an occasional top up, results usually last one to three years. Cutting back on coffee, tea, red wine, and tobacco keeps your smile bright much longer.
Is whitening safe for sensitive teeth?
In most cases yes. We assess your enamel and gums first, use a desensitising agent, and can lower the gel strength or move you to gentler take home trays. Tell us about your sensitivity and we will plan around it.
Can I walk in for teeth whitening?
Yes. We welcome walk ins 7 days a week until midnight Monday to Saturday. Call ahead on (647) 931-6696 if you want us to hold an hour for you.
Is teeth whitening covered by insurance or CDCP?
Whitening is a cosmetic treatment, so most plans and CDCP do not cover it. If your plan includes cosmetic coverage we will bill it directly. Any cleaning or treatment you need beforehand is often covered.
What is the difference between teeth whitening and teeth cleaning?
Teeth cleaning removes plaque, tartar, and surface stains to protect your oral health and prevent gum disease. Whitening is cosmetic and lightens the natural colour of your teeth. Cleaning keeps teeth healthy, whitening makes them visibly brighter.
Do you have a Persian speaking dentist?
Yes. Our team speaks Persian as well as English, so you can discuss your treatment comfortably in either language.
