Teeth whitening cost in Ontario depends on the method. Store-bought strips are usually cheapest, dentist-supervised take-home whitening with custom trays costs more, and in-office whitening usually costs the most. Each dental office sets its own fees. Because whitening is cosmetic, private dental plans and the CDCP generally do not cover it, so most people pay out of pocket.
The headline price matters less than what it includes and whether whitening suits your teeth. This guide from Barton Dental explains how professional whitening prices in Ontario are set, how clinic, take-home and store-bought options compare, what affects the cost, which stains respond, what insurance covers and what maintenance costs over time. It also explains how whitening works at our office in Hamilton.
How Are Professional Whitening Prices in Ontario Set?
Professional whitening prices in Ontario are set by each dental office. Many dentists use the Ontario Dental Association’s annual Suggested Fee Guide as a reference for their services, but they are not required to follow it, so prices for similar whitening treatments vary between practices, including within Hamilton.
The Ontario Dental Association explains that office overheads, location and the time a service takes all influence fees. For take-home whitening, the fee typically reflects the assessment, the custom trays made from impressions or scans of your teeth, the professional whitening gel and follow-up advice. For in-office whitening, it reflects chair time and the stronger materials used under direct supervision.
Clinic, Take-Home or Store-Bought: How Do the Options Compare?
The three main ways to whiten teeth differ in cost, supervision and fit. Store-bought products are least expensive but use generic strips or trays. Dentist-supervised take-home whitening uses custom trays and professional gel with an assessment first. In-office whitening applies stronger gel in the chair and is usually the most expensive.
| Option | How It Works | Relative Cost | Professional Assessment | Typical Timeframe |
| Whitening toothpaste | Mild abrasives remove surface stains | Lowest | No | Gradual, surface stains only |
| Store-bought strips or kits | Low-strength gel on generic strips or trays | Low | No | About 1 to 2 weeks of daily use |
| Supervised take-home whitening | Custom-fitted trays with professional gel | Moderate | Yes | Usually 1 to 3 weeks |
| In-office whitening | Higher-strength gel applied by the dental team | Highest | Yes | Often one longer visit |
Custom trays fit closely, which helps keep the gel on the teeth and away from the gums. They can usually be reused for touch-ups, which lowers the cost of maintenance later. The Canadian Dental Association notes that in-office techniques, particularly those using lasers and lights, have undergone little scientific assessment, so a light on its own is not a reason to pay more.
What Affects Teeth Whitening Cost in Ontario?
The main factors in teeth whitening cost in Ontario are the method, whether custom trays are made, how much gel is included, treatment needed before whitening and the type of staining. Visible crowns or fillings that will not whiten can also add to the overall budget if they need replacing to match.
- Method. Supervised take-home whitening generally costs less than in-office treatment and more than store-bought products.
- Custom trays. Made from impressions or scans, they add to the first fee but can be reused.
- Gel quantity. Ask how many days of treatment the fee covers and what refills cost.
- Treatment first. Cavities and gum disease must be treated before whitening. A dental cleaning beforehand removes surface stain so you see your true starting shade.
- Existing restorations. Crowns, veneers and fillings keep their colour, so front restorations may need replacing to match after whitening.
Will Whitening Work on Your Stains?
Whitening works best on surface (extrinsic) stains from coffee, tea, red wine and tobacco, and often helps with age-related yellowing. Stains inside the tooth (intrinsic), such as those from tetracycline antibiotics, fluorosis or trauma, respond less predictably. Knowing your stain type before you pay helps you avoid spending on a result you will not get.
| Stain Type | Common Causes | How Whitening Usually Responds |
| Surface (extrinsic) | Coffee, tea, red wine, tobacco | Usually responds well |
| Age-related | Thinning enamel showing yellower dentine | Often improves to a degree |
| Intrinsic | Tetracycline, fluorosis | Less predictable; may need other treatment |
| Single dark tooth | Trauma or a previous root canal | Needs assessment; surface whitening may not help |
Health Canada notes that whitening products work only on natural teeth and do not change the colour of caps, crowns, veneers, fillings or dentures. Typical home-use products are used over 10 to 14 days and are generally safe when directions are carefully followed, according to Health Canada’s guidance on the safe use of home tooth whitening kits. Our article on coffee and wine stains explains how common stains form.
What Is Included in the Price of Professional Whitening?
The price of professional take-home whitening usually includes an assessment, impressions or scans, custom-made trays, an initial supply of whitening gel and instructions, and sometimes a follow-up shade check. Exams, X-rays and cleanings are often billed separately, so check what your estimate covers.
Questions to ask before you book:
- Is the dental exam included, or a separate fee?
- Are custom trays included, and do I keep them?
- How much gel is included, and what do refills cost?
- Is a follow-up visit included?
- Will I need a cleaning or other treatment first?
If you have used store-bought products before without success, mention it at your assessment, because it can point to stains that need a different approach. Comparing itemized estimates is more useful than comparing headline prices, because a cheaper quote may leave out trays or follow-up you will need anyway.
Does Insurance or the CDCP Cover Teeth Whitening?
Teeth whitening is not usually covered by dental insurance in Ontario because it is a cosmetic treatment. The Canadian Dental Care Plan lists cosmetic treatment, including teeth whitening, as an exclusion, and OHIP does not cover dental care in a dentist’s office. The exam and cleaning that often come before whitening may be covered under your plan’s preventive benefits.
The CDCP Dental Benefits Guide lists teeth whitening among its exclusions, which are never eligible for reconsideration. Private plans vary but nearly always classify whitening as cosmetic. If you have a health spending account through work, check its rules; accounts that follow the Canada Revenue Agency’s definition of eligible medical expenses generally exclude purely cosmetic procedures such as teeth whitening.
What Does Whitening Cost Over Time?
Whitening results are not permanent, so the long-term cost includes occasional touch-ups. Coffee, tea, red wine, tobacco and natural ageing gradually darken teeth again. With custom trays, touch-ups usually need only more gel rather than a full new treatment, which keeps ongoing costs lower.
Ways to make results last:
- Rinse with water after coffee, tea or red wine, and use a straw for iced drinks.
- Avoid tobacco, one of the strongest causes of staining.
- Keep regular professional cleanings to remove surface stain and tartar.
- Store your trays in their case and keep them away from heat so they keep their fit.

What Happens During Supervised Take-Home Whitening?
Supervised take-home whitening starts with a dental assessment, then impressions or scans for custom trays. You receive your trays, gel and instructions, whiten at home for the recommended period and check in if you have sensitivity. Most courses take one to three weeks.
- Assessment. Your dentist checks teeth and gums, identifies the type of discolouration and notes restorations that will not whiten.
- Impressions or scans. These are used to make trays that fit your teeth closely.
- Trays and instructions. You learn how much gel to use, how long to wear the trays and how to manage sensitivity.
- Home whitening. You follow the recommended schedule, usually daily over one to three weeks.
- Follow-up and maintenance. You keep your trays for occasional touch-ups with extra gel.
Who Should Wait Before Whitening?
Some people should wait or choose a different approach. Whitening is generally postponed until active decay and gum disease are treated, and many dentists suggest delaying cosmetic whitening during pregnancy and breastfeeding as a precaution. People with very sensitive teeth, exposed roots or large visible restorations should discuss options first.
If whitening is not suitable now, your dentist may suggest treating the underlying problem first, a professional cleaning to remove surface stain, or other cosmetic options such as bonding or veneers for teeth that do not respond to whitening. If your teeth are already sensitive, our article on teeth whitening for sensitive teeth explains how to approach it.

Frequently Asked Questions
Why does dentist whitening cost more than store-bought strips?
The dentist’s fee covers an assessment, trays custom-made for your teeth, professional-strength gel and advice on sensitivity and realistic results. Store-bought strips use generic shapes and lower-strength gel with no professional check. The extra cost pays for suitability screening, a better fit and support during treatment.
Is take-home whitening as effective as in-office whitening?
Both can lighten natural teeth when used correctly. In-office whitening gives faster results in one longer visit, while take-home whitening reaches its result over one to three weeks. Take-home trays can also be reused for touch-ups. Your dentist can advise which suits your stains, schedule and sensitivity.
Will whitening change the colour of my crowns or fillings?
No. Health Canada notes that whitening products work only on natural teeth. Crowns, veneers and fillings keep their original colour, so visible restorations may look different after whitening. Discuss this before you start, as you may want to budget for replacing them to match your new shade.
Does teeth whitening make teeth sensitive?
It can. Temporary sensitivity, often to cold, is the most common side effect and usually settles once you pause or finish treatment. Using a desensitizing toothpaste before and during whitening, following wear times and taking breaks can help. Contact your dentist if sensitivity is strong or lasts.
How often will I need to touch up my whitening?
It depends on your habits. People who drink a lot of coffee, tea or red wine, or who smoke, usually need touch-ups more often. With custom trays, a short touch-up with extra gel every so often keeps results fresh. Your dentist can suggest a maintenance schedule that suits you.
