Most patients who search “teeth whitening cost” want a real number before they call anyone. That makes complete sense. Showing up to a consultation with no idea what to expect financially is an uncomfortable starting point.
Professional teeth whitening has a clear price range, and where your treatment falls within that range depends on your starting shade, the level of staining, and what your teeth actually need. We look at your teeth, discuss your goals, and explain costs honestly before anything is scheduled.
Dentist-supervised take-home whitening in London, Ontario typically costs between $200 and $500 CAD. The final price depends on how much customization your case requires, the level of staining involved, and the treatment approach recommended during your consultation.
During your consultation, we examine your teeth, review your goals, and confirm which option fits your situation before anything is booked.
Here is how dentist-supervised take-home whitening compares to over-the-counter alternatives:
| Treatment Type | What It Involves | Estimated Cost Range |
|---|---|---|
| Dentist-Supervised Take-Home Trays | Custom-fitted trays made from impressions of your teeth, filled with professional-grade gel and worn at home over a period of days to weeksTeeth Whitening Cost by Treatment Type | $200 - $500 |
| Over-the-Counter (OTC) Products | Generic strips, pens, or paint-on gels available at pharmacies without a prescription | $30 - $100 |
Dentist-supervised take-home whitening uses custom-fitted trays made from precise impressions of your teeth. You fill the trays with professional-grade whitening gel and wear them at home following the schedule we set out for you at your consultation.
Because the trays are made specifically for your teeth, the gel sits evenly against each tooth surface and stays in place during wear. This reduces the risk of uneven whitening, gel contact along the gumline, and unnecessary sensitivity compared to over-the-counter alternatives.
The process is gradual. Most patients complete their whitening over a period of days to a few weeks, depending on their starting shade, the level of staining, and the shade goal they want to reach. We provide written instructions and are available if any questions come up during treatment.
The right timing and gel concentration for your case depend on your starting shade, the type of staining, your sensitivity history, and your schedule. We go through all of this at your consultation before any trays are made.
Within that cost range, several factors specific to your case will shape the final fee:
We go over the fee before treatment begins so you can make a fully informed decision.
Surface stains from coffee, tea, red wine, and tobacco often respond well to whitening. Deeper staining can be less predictable and may require a more customized plan or a longer whitening schedule to achieve the result you are looking for.
The longer staining has been present, the more carefully we need to plan treatment. We would rather be upfront about what whitening can realistically achieve for your teeth than promise a shade change that may not be attainable.
Take-home whitening and touch-up whitening each involve different gel concentrations, wear schedules, and planning requirements. A custom take-home system delivers results gradually over days to weeks using professional-grade gel applied through a precisely fitted tray. Touch-up whitening, used after an initial whitening course, typically involves a shorter wear schedule and a lower volume of gel.
The treatment approach affects cost because it affects tray fabrication, the products used, and the level of monitoring and follow-up guidance involved.
Many patients see noticeable improvement within the first week of take-home whitening. Others may need a longer schedule or a follow-up maintenance phase over time. The duration of treatment depends on:
We help set realistic expectations before treatment begins, so there are no surprises about what whitening can and cannot do for your specific teeth.
Whitening works on natural tooth enamel. Crowns, veneers, bonding, and tooth-coloured fillings do not respond to whitening the same way natural teeth do. If you have visible restorations on your front teeth, we need to consider shade matching before recommending a whitening approach.
Whitening may also need to wait if there are untreated cavities, active gum inflammation, exposed root surfaces, or significant sensitivity. In those cases, your oral health comes first.
Professional teeth whitening is considered a cosmetic treatment by most dental insurance plans, which means it is generally not covered. Coverage depends entirely on the terms of your specific plan. Some plans exclude cosmetic dental procedures altogether; others may offer limited coverage in certain circumstances.
It is worth checking your policy or calling your benefits provider before your appointment, since the answer varies from plan to plan.
If you are unsure whether your plan covers whitening, a few questions worth asking before you come in:
Having that information ready allows us to assist with claim submission accurately and efficiently.
Our team can help with insurance claim submission when applicable. While whitening is typically considered cosmetic and coverage is limited in most cases, we can assist with the process and make sure you understand your out-of-pocket cost before treatment begins.
For patients where financing would make treatment easier to manage, eligible patients may also explore LendCare financing through our office.
For patients who prefer to spread the cost of whitening over time, payment plans can be discussed at your consultation. Structured payments are one way we help make treatment more accessible without requiring the full fee upfront.
The schedule and arrangement depend on your specific treatment fee and financial situation. We work through the options with you before you commit to anything.
Whitening toothpaste can help remove some surface staining over time and may be useful for maintaining results after professional whitening. It does not produce the same level of shade change as peroxide-based bleaching and is not a substitute for professional dental cleaning or dentist-supervised treatment.
Used too aggressively, abrasive whitening formulas can also irritate sensitive teeth or gum tissue. We can suggest a non-abrasive option when appropriate.
Over-the-counter products include strips, pens, and paint-on gels. They are affordable and accessible, but they are designed for general use rather than for your specific teeth. The whitening gel does not always sit evenly against each tooth surface, particularly near edges, on uneven enamel, or along the gumline. The result can be patchy whitening, gum irritation, or increased sensitivity.
These products may be appropriate for mild staining or maintenance between professional treatments, but they do not include an oral health assessment. That matters because cavities, gum recession, exposed roots, or existing dental work can affect whether whitening is appropriate for you in the first place.
Custom dentist-supervised whitening is planned around your mouth, not a shelf label. At We Smile Dentistry, we assess your enamel condition, existing restorations, and sensitivity before recommending an approach. The result is a plan that accounts for what your teeth actually need, rather than a product calibrated for an average set of teeth.
Dentist-supervised take-home whitening delivers more consistent, even results than store-bought alternatives because the trays are made specifically for your teeth. Professional-grade gel sits evenly against each tooth surface and is applied following a protocol tailored to your starting shade, sensitivity history, and shade goal rather than a one-size-fits-all approach.
Professional supervision also allows us to guide the whitening process more carefully, which helps reduce the risk of uneven colour. This is especially relevant if you have crowded teeth, uneven edges, or areas that tend to stain differently from the rest.
Your whitening plan should match your teeth. We look at your starting shade, sensitivity history, enamel condition, existing dental work, and the reason your teeth appear dull or discoloured. That allows us to recommend an approach that is practical, realistic, and appropriate for your specific smile. A store-bought product cannot make that assessment. A professional consultation can.
Dark or acidic foods and drinks are among the most common reasons whitening fades faster than expected. Sources that tend to contribute to staining include:
You do not have to eliminate everything on that list. Rinsing with water after staining drinks, keeping up with regular dental cleanings, and following any post-treatment guidance we provide can help extend your results in a practical, sustainable way.
Maintaining your results does not require an intensive routine. We may recommend:
Whitening is not always the right answer. It may not be suitable if you have:
In those cases, we may recommend treating oral health concerns first or discussing cosmetic alternatives such as bonding or veneers when appropriate.
We do not treat whitening as a quick add-on. We listen to your goals, examine your teeth and gums, review sensitivity concerns, and consider any existing restorations that could affect the final shade.
If whitening is likely to help, we explain your options clearly. If whitening has limitations in your case, we say that too.
Our dentist-supervised take-home whitening is planned with attention to custom tray fit, even gel application, gum protection, and patient comfort. This approach helps reduce the risk of irritation, uneven colour change, and unnecessary sensitivity.
