Teeth Whitening in Mississauga

Professional teeth whitening in Mississauga lightens stains and yellowing that brushing can’t remove. Also called dental bleaching, it’s one of the quickest ways to brighten your smile, whether you have a wedding coming up or you’re simply tired of coffee stains. At River Run Dental Centre, our dentists offer whitening for adults, with in-office treatment and custom take-home trays.
Before we whiten, your dentist checks your teeth and gums so the treatment is safe and the result looks natural. We’re open 7 days a week, including weekday evenings and Sundays.
Benefits of Professional Teeth Whitening
Store-bought strips use weaker gel and one-size trays, so results are often patchy and slow. Whitening from your dentist uses a stronger gel in trays made for your teeth, with your gums protected.
Lifts coffee, tea, wine and smoking stains
Even, natural-looking results
Custom trays that protect your gums
Safe for most adults after a dental check

What Happens During Teeth Whitening
Whitening starts with a short exam to make sure your teeth are healthy enough to bleach. Then you choose the option that suits you.
Exam and Shade Check
Your dentist checks for cavities and gum problems and records your starting shade.
In-Office Whitening
We protect your gums, then apply a professional whitening gel in one visit of about an hour.
Take-Home Trays
Or we make custom trays from a scan or impressions, and you whiten at home over one to two weeks.
Some people notice mild tooth sensitivity for a day or two after whitening. It fades on its own, and a sensitivity toothpaste helps. Whitening doesn’t change the colour of fillings, crowns or veneers, so your dentist will tell you if any of those might need replacing to match.
Why Choose River Run for Teeth Whitening
Whitening is only worth doing if it’s safe and looks natural. Our dentists check your teeth first and help you pick a shade that suits you, not just the brightest one on the chart.

Dentist-Supervised Whitening
Your dentist checks your teeth and gums first and follows up if you feel any sensitivity.

Teeth Whitening Cost in Mississauga
Teeth whitening cost in Mississauga depends mostly on the method. In-office whitening costs more because it’s done in one visit by your dental team. Take-home trays cost less and work more slowly. The price also depends on how stained your teeth are and whether you need a cleaning first. The average cost of teeth whitening in Ontario varies a lot between clinics and methods, so ask what’s included when you compare whitening fees, such as custom trays for use at home.
With insurance: most dental plans treat whitening as cosmetic and don’t cover it. The checkup and cleaning you have before whitening usually is covered.
Without insurance: ask for a teeth whitening price when you book, so you know the cost before your visit. If you’re comparing cheap teeth whitening kits, keep in mind that professional results are more even and usually last longer.
The Canadian Dental Care Plan (CDCP) doesn’t cover cosmetic treatments like whitening, but it can cover your exam and cleaning beforehand.
We Direct Bill Your Dental Insurance
Pay only your share at your visit. We accept most private dental plans, the Canadian Dental Care Plan and several government programs, and we offer payment plans if you don't have insurance.

Does Teeth Whitening Work on Yellow or Stained Teeth?
The most common causes of stained teeth are coffee, tea, red wine, curry and smoking. Yellow teeth are also a normal part of ageing, as enamel wears thinner and the yellower layer underneath shows through.
Whitening works best on these yellow and surface stains, and most people see their teeth get several shades lighter. It works less well on:
- Grey or brown staining from certain antibiotics taken in childhood
- A single dark tooth, often after an old injury or root canal
- Fillings, crowns, bonding and veneers, which don’t change colour
For these, your dentist may suggest dental veneers or dental bonding instead.
To keep your results, rinse with water after dark drinks, brush twice a day and keep up with regular cleanings. Many people do a short touch-up with their take-home trays once a year.
Who Can Get Teeth Whitening?
Most adults with healthy teeth and gums can whiten. We usually suggest waiting, or starting with a checkup, if:
- You’re a teen and your adult teeth are still settling in
- You’re pregnant or breastfeeding
- You have untreated cavities, gum disease or worn enamel
- Your teeth are very sensitive, in which case a gentler take-home plan may suit you better
Not sure if whitening is right for you? Ask at your next checkup and we’ll go over your options.

Teeth Whitening in Mississauga: Frequently Asked Questions
It depends on whether you choose in-office whitening or take-home trays, and how stained your teeth are. In-office whitening costs more but is done in one visit. We give you a price before you decide. Most insurance plans don't cover whitening because it's cosmetic.
Whitening isn't painful for most people, but some feel mild sensitivity for a day or two afterwards. We protect your gums during treatment, and a sensitivity toothpaste helps. If your teeth are already sensitive, tell us and we'll adjust the plan.
Usually one to three years, depending on your habits. Coffee, tea, red wine and smoking bring stains back faster. Rinsing after dark drinks, regular cleanings and an occasional top-up with your trays help results last.
Zoom is one well-known brand of in-office whitening. Most in-office systems work the same way: a professional gel is applied in one visit while your gums are protected. If you're comparing Zoom teeth whitening prices, ask us which system we use and how the cost compares.
Professional whitening uses a stronger gel and trays made to fit your teeth, so results are faster and more even. Your dentist also checks for cavities and gum problems first, which strips can't do.
Usually not. Most workplace plans and the Canadian Dental Care Plan treat whitening as cosmetic. They often cover the exam and cleaning you may need beforehand, so check your plan or ask us.
No. Whitening only lightens natural teeth. If you have crowns or fillings on your front teeth, your dentist will explain whether they'd need replacing after whitening so everything matches.
Brush twice a day, floss, cut back on coffee, tea and smoking, and rinse with water after dark drinks. Whitening toothpaste removes some surface stains. For deeper yellowing, professional whitening works much better than home remedies.
