Teeth whitening cost in Mississauga depends on the type of whitening and what is included. In-office whitening done in a dental chair usually costs the most, dentist-supervised take-home trays usually cost less, and store-bought strips cost the least but are not fitted to your teeth. At Tomken Dental, professional whitening is provided as take-home treatment with custom-fitted trays, starting with an assessment of your teeth and gums. This guide explains typical professional whitening prices in Mississauga, what each option includes, what affects the cost, and how to make results last.
How Much Does Teeth Whitening Cost in Ontario?
| Option | Typical price range in Ontario | What is usually included |
| In-office whitening | About $400 to $900 per session | Exam, gum protection, professional gel applied in the clinic |
| Dentist take-home whitening trays | About $200 to $500 | Assessment, custom-fitted trays, professional gel, instructions, follow-up |
| Touch-up gel for existing trays | About $50 to $150 | Additional gel for reusable trays |
| Store-bought strips or kits | About $30 to $100 | Ready-made product, no exam or follow-up |
These are general Ontario estimates, not Tomken Dental’s fee schedule. Independent pricing research based on provincial suggested-fee guides puts in-office whitening in Canada at roughly $400 to $900 per session in 2026; the other ranges are general market estimates. Your actual cost is confirmed after an assessment.
What Teeth Whitening Option Does Tomken Dental Offer?
Tomken Dental provides take-home professional whitening with custom trays made from impressions of your teeth. The process includes:
1. Pre-whitening assessment: your teeth, gums, and existing restorations are checked, your starting shade is noted, and any cleanings or restorative work are scheduled first.
2. Impressions for custom trays: digital or physical impressions are taken; trays are typically ready within one to two business days.
3. Tray fitting and instructions: you learn how to apply the gel, how long to wear the trays, and how to manage sensitivity.
4. Whitening at home: most patients wear the trays for 30 to 60 minutes a day over one to two weeks.
5. Follow-up and touch-ups: your result is checked, and the trays can be reused with additional gel for future touch-ups.

In-Office vs. Take-Home vs. Store-Bought Whitening
| Feature | In-office | Dentist take-home trays | Store-bought strips |
| Relative cost | Highest | Middle | Lowest |
| Speed | Change often seen after one visit | Gradual over one to two weeks | Gradual; varies |
| Fit | Gum protection applied in clinic | Custom trays fitted to your teeth | One size fits all |
| Supervision | Dentist controls the session | Dentist sets the plan and follows up | None |
| Touch-ups | Usually another visit | Reuse trays with extra gel | Buy new product |
| Sensitivity control | Managed in clinic | Easy to shorten wear or pause | Limited |
Each option can work for the right person. Take-home trays suit people who want professional guidance at a lower cost than in-office treatment and the flexibility to whiten at home.
What Affects Professional Whitening Prices in Mississauga?
• Type of whitening: in-office sessions involve chair time, while take-home whitening involves custom trays and gel.
• Custom trays: trays made from impressions fit closely and can be reused, which affects the upfront cost.
• Amount of gel: a longer course or more touch-up gel adds cost.
• Pre-whitening care: a cleaning or treatment of cavities or gum disease may be needed first and is usually billed separately.
• Sensitivity management: desensitizing toothpaste or a gentler plan may be part of your care.
• Your starting shade and stain type: deep or stubborn discolouration may need more time, or a different treatment.

Does Insurance Cover Teeth Whitening?
Teeth whitening is a cosmetic treatment, so most dental plans do not cover it. The exam and cleaning that often come before whitening may be covered under your plan. The Canadian Dental Care Plan focuses on oral health services rather than cosmetic treatment. Ask for an estimate that separates covered and non-covered items before you start.
Who Should Check With a Dentist Before Whitening?
Whitening may not be right for you yet if you have:
• Cavities or gum disease that need treatment first
• Very sensitive teeth or exposed roots
• Visible crowns, veneers, or bonding on front teeth, which will not change colour
• Discolouration from certain medications or a past injury, which may not respond fully
Health Canada offers guidance on the safe use of home whitening kits, and the Canadian Dental Association’s position on tooth bleaching supports bleaching as generally safe and effective under a dentist’s supervision.
What Results Can You Realistically Expect?
Whitening lightens natural tooth enamel. It does not change the colour of crowns, veneers, bonding, or fillings. Surface stains from coffee, tea, wine, and tobacco usually respond well, and age-related yellowing often lightens. Discolouration from certain antibiotics or trauma may not respond fully. Results depend on your starting shade, stain type, and how consistently you follow the plan, so your dentist will discuss a realistic target at the assessment.
How Long Do Whitening Results Last?
Results are not permanent. Diet, habits, and ageing gradually re-stain teeth. With reusable custom trays, many people do short touch-ups once or twice a year to maintain their shade. To protect your results:
• Rinse with water after coffee, tea, or wine.
• Use a straw for dark drinks when practical.
• Avoid tobacco.
• Brush twice a day and keep up regular cleanings.
• Avoid strongly staining foods and drinks for about 48 hours after completing a whitening course.
Planning Whitening Around Other Cosmetic Work
If you are planning veneers, bonding, or crowns, whiten first so the new restorations can be matched to your brighter shade. Tomken Dental recommends waiting about two weeks after whitening for the shade to stabilize before shade-matching restorations.

Managing Sensitivity During Whitening
Temporary sensitivity is the most common side effect. To reduce it:
• Use a toothpaste for sensitive teeth for about two weeks before starting.
• Shorten daily wear time, or take a day off when needed.
• Avoid very cold drinks during the whitening period.
• Ask about lower-concentration gels if you have sensitive teeth.
• Contact your dentist if sensitivity is strong or lasts.
What Is Included in a Professional Whitening Quote?
| Item | Usually included in take-home whitening? |
| Pre-whitening assessment | Often included or billed as an exam |

| Custom trays | Yes |
| Initial supply of professional gel | Yes |
| Fitting and instructions | Yes |
| Follow-up shade check | Often |

Ask which items your quote covers so you can compare offices fairly.
Is Professional Whitening Worth the Cost?
For many people, professional whitening offers better fit, supervision, and safer results than store products, while costing far less than cosmetic treatments such as veneers. Take-home trays are reusable, so the long-term cost of touch-ups is mainly additional gel. Whether it is worth it depends on your goals, your stain type, and whether your teeth and gums are healthy enough to whiten. Your dentist can tell you if whitening is likely to meet your expectations, or whether another option, such as bonding or veneers, would suit you better.
What Causes Tooth Discolouration?
| Type | Common causes | Response to whitening |
| Surface (extrinsic) stains | Coffee, tea, red wine, tobacco | Usually responds well |
| Age-related yellowing | Thinning enamel and darker dentine | Often lightens |
| Internal (intrinsic) staining | Certain antibiotics, trauma, excess fluoride in childhood | May not respond fully |
| Single dark tooth | Past injury or root canal | Often needs other treatment |
Understanding the cause helps your dentist recommend the right approach and avoid spending money on whitening that will not meet your expectations.
Questions to Ask Before You Start
• Are my teeth and gums healthy enough for whitening?
• Will my crowns, veneers, or fillings need replacing to match?
• What results are realistic for my type of staining?
• How long will the course take, and how often will I need touch-ups?
• What does the quote include, and what costs extra?
• How can I manage sensitivity?
Whitening for Special Events
If you are whitening before a wedding, graduation, or interview, start about two to four weeks ahead. This gives time for trays to be made, for a full course of whitening, and for any sensitivity to settle. Avoid starting a new whitening product the night before an event.
How Take-Home Whitening Works Day to Day
After your trays are fitted, you place a small amount of professional gel in each tray and wear them for the time your dentist recommends, usually 30 to 60 minutes a day. Many people whiten in the evening after brushing. Results appear gradually, with noticeable change often within the first few days of consistent use. Wearing the trays longer than recommended does not produce proportionally better results and can increase sensitivity, so follow the plan you are given. Keep the gel refrigerated when not in use, and avoid strongly staining foods and drinks during the whitening period.
Comparing the Total Cost Over Time
| Option | Upfront | Ongoing |
| In-office whitening | Highest per session | Repeat sessions for touch-ups |
| Dentist take-home trays | Moderate | Extra gel for reusable trays |
| Store-bought strips | Lowest | Repeat purchases; results vary |
Looking at the total cost over a few years, rather than one purchase, often gives a clearer picture of value. Reusable custom trays can make maintenance more economical.
Professional Whitening Prices in Mississauga: What to Remember
Professional whitening prices in Mississauga vary between offices because of differences in what is included, the type of gel, and whether a cleaning or exam is bundled. The most useful comparison is not just the headline price but the full package: assessment, custom trays, gel, follow-up, and touch-up options. An honest assessment of whether whitening will meet your goals is part of good value.
Common Myths About Whitening Costs
• “Store strips give the same result for less.” They are not fitted to your teeth and results vary.
• “Whitening is a one-time cost.” Touch-ups are usually needed over time.
• “Insurance covers whitening.” It is usually considered cosmetic.
• “Wearing trays longer works faster.” Longer wear raises the risk of sensitivity without proportionally better results.
Whitening and Your Overall Oral Health
Whitening works best on clean, healthy teeth. Regular check-ups and cleanings remove tartar and surface stains, treat small problems early, and help your whitening results look even. If you are new to Tomken Dental, an exam and cleaning before whitening also give the dentist a chance to check for cavities, gum disease, or worn fillings that could affect your results or comfort. Treating these first protects your teeth and helps you get value from the money you spend on whitening.
