How Much Does Professional Teeth Whitening Cost in London, ON?

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.

What Is the Average Cost of Teeth Whitening in London, Ontario?

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.

Teeth Whitening Cost by Treatment Type

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
*These are general Ontario market estimates. Your actual fee depends on your starting shade, the level of staining, your sensitivity history, and the treatment approach recommended during your consultation.*

Dentist-Supervised Take-Home Whitening: What to Expect

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.

What Impacts the Final Price?

Within that cost range, several factors specific to your case will shape the final fee:

  • The gel concentration and protocol recommended for your case
  • The complexity of tray fabrication and fitting
  • The level and type of staining present
  • The amount of appointment time involved in taking impressions and fitting trays
  • Any oral health concerns that need to be addressed before whitening can begin
  • Whether whitening is being coordinated with other cosmetic work such as bonding, veneers, or crowns

We go over the fee before treatment begins so you can make a fully informed decision.

Factors That Affect Teeth Whitening Cost

Level of Tooth Staining

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.

Type of Whitening Treatment

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.

Number of Sessions Needed

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:

  • How dark or discoloured the teeth are before whitening begins
  • Whether staining is surface-level or deeper
  • How sensitive the teeth are during treatment
  • The shade goal you want to reach
  • How your teeth respond to the whitening gel

We help set realistic expectations before treatment begins, so there are no surprises about what whitening can and cannot do for your specific teeth.

Existing Dental Conditions

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.

Does Insurance Cover Teeth Whitening in Ontario?

Whitening and Cosmetic Coverage

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.

What to Ask Your Benefits Provider

If you are unsure whether your plan covers whitening, a few questions worth asking before you come in:

  • Does my plan include any cosmetic dental benefits?
  • Is professional teeth whitening excluded explicitly?
  • Are there any circumstances where whitening might qualify for partial coverage?
  • What is the submission process if any portion is eligible?

Having that information ready allows us to assist with claim submission accurately and efficiently.

How We Smile Dentistry Assists With Claims

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.

Teeth Whitening Payment & Financing Options in London, ON

Monthly Payment Options

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.

Flexible Financing Solutions

Eligible patients can access financing through LendCare, which allows qualifying patients to begin treatment now and manage the cost over a longer term. Eligibility and terms are determined through the application process. We can walk you through how to explore this option during your visit.

Making Whitening More Affordable

Whether through a payment plan, applicable insurance benefits, or LendCare financing, we look for the combination that fits your situation. All fees and terms are reviewed in full before treatment begins.

Professional Whitening vs Store-Bought Products

Whitening Toothpaste

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.

Whitening Strips and Over-the-Counter Kits

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

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.

Is Professional Teeth Whitening Worth It?

Even, Consistent Results

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.

Personalized Treatment Approach

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.

Reduced Risk of Sensitivity and Irritation

Whitening gel can irritate gum tissue and soft tissues if it spreads where it should not. Custom-fitted trays keep the gel precisely in place against each tooth surface, which helps protect the gums, lips, and surrounding tissue during treatment. If sensitivity develops, we can adjust timing, product concentration, or the wear schedule to keep treatment as comfortable as possible.

How Long Do Teeth Whitening Results Last?

Teeth whitening results are not permanent. How long your brighter shade lasts depends on your oral care habits, diet, tobacco use, enamel condition, and how often your teeth come into contact with staining foods and drinks.

Foods and Drinks That Affect Results

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:

  • Coffee and tea
  • Red wine
  • Dark soft drinks
  • Berries and berry-based juices
  • Tomato-based sauces
  • Curry and turmeric-heavy foods
  • Dark condiments such as soy sauce and balsamic vinegar

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.

Lifestyle Habits That Speed Up Fading

Tobacco use is among the most significant contributors to post-whitening staining. Smoking and other forms of tobacco can rapidly stain teeth and accelerate fading regardless of how well the initial whitening treatment went. If tobacco staining is a concern, we can discuss what whitening can realistically achieve and how often maintenance may be needed.

Whitening Maintenance Tips

Maintaining your results does not require an intensive routine. We may recommend:

  • Brushing twice daily with a fluoride toothpaste
  • Flossing daily
  • Attending regular professional cleanings
  • Rinsing with water after coffee, tea, or wine
  • Using a straw for dark drinks when practical
  • Avoiding tobacco
  • Using touch-up whitening only as directed
  • Choosing a non-abrasive whitening toothpaste when appropriate

Who Is a Good Candidate for Teeth Whitening?

A good whitening candidate typically has healthy teeth and gums, natural enamel that can respond to whitening, and staining that is likely to lighten with bleaching. A consultation helps us confirm whether whitening is the right fit or whether a different cosmetic approach would produce a better result.

Surface Stains from Coffee, Tea, Wine, and Tobacco

Whitening is often well suited to surface stains caused by everyday foods, drinks, and tobacco. These extrinsic stains (stains on the tooth surface) can make teeth look dull, yellow, or uneven even when the teeth themselves are structurally healthy. If staining is mostly external, whitening may help create a cleaner, brighter appearance without altering the shape or structure of the teeth.

Age-Related Yellowing

Teeth naturally darken with age as enamel changes and stains accumulate over time. Whitening may help brighten natural teeth affected by age-related yellowing, though results can vary depending on enamel thickness and the depth of discolouration. We will discuss what is realistic for your smile before treatment begins.

When Whitening May Not Be the Best Option

Whitening is not always the right answer. It may not be suitable if you have:

  • Untreated cavities
  • Active gum inflammation
  • Exposed root surfaces
  • Significant existing sensitivity
  • Intrinsic stains (inside the tooth structure) that do not respond to bleaching
  • Crowns, veneers, fillings, or bonding on visible front teeth
  • A shade goal that whitening alone cannot realistically achieve

In those cases, we may recommend treating oral health concerns first or discussing cosmetic alternatives such as bonding or veneers when appropriate.

Frequently Asked Questions About Teeth Whitening Cost

Is professional teeth whitening covered by insurance?

Professional teeth whitening is considered a cosmetic treatment by most dental insurance plans, so coverage is generally not included. Coverage depends on your individual policy. Our team can help you understand what questions to ask your provider and assist with claim submission when applicable.
Shade improvement varies from patient to patient. The result depends on your starting colour, the type of staining, your enamel condition, age-related changes, and whether any visible restorations are present. We assess your smile during the consultation and give you an honest picture of what improvement is realistic for your specific teeth.
Some patients notice temporary sensitivity to hot and cold temperatures while using their take-home whitening trays. This usually settles within a few days of completing treatment. If you already have sensitive teeth, we can adjust the gel concentration, wear schedule, or maintenance plan to make treatment more comfortable.
Whitening frequency depends on your enamel condition, sensitivity history, diet, and previous whitening treatments. Since results are not permanent, touch-ups may be appropriate over time, but whitening too frequently is not ideal and can affect enamel health. We recommend a schedule based on your specific situation.
Getting started with take-home whitening involves two steps. The first is a consultation and tray-fitting appointment, during which we examine your teeth, discuss your goals, take impressions, and have your custom trays made. Once your trays are ready, you begin wearing them at home following the schedule we provide. Most take-home whitening courses run over a period of days to a few weeks depending on your starting shade and shade goal. We go through the full expected timeline with you before anything is confirmed.
