Why Choose Professional Teeth Whitening?
Over-the-counter whitening strips and toothpastes can lighten surface stains, but they rarely deliver the dramatic, even results patients expect. At Dentistry at LaSalle in Burlington, ON, our professional whitening treatments use higher-concentration gels applied under clinical supervision, which means faster results, better colour consistency, and reduced sensitivity.
Whether your teeth have yellowed from coffee, tea, red wine, or simply the passage of time, our Burlington team can help you achieve a noticeably brighter smile — safely and predictably.
In-Office Whitening
Our in-office whitening procedure is ideal for patients who want immediate results. In roughly one hour at our Burlington dental suite, we can lighten your teeth by several shades. Here is what to expect:
- Shade assessment — We record your starting shade so you can see the improvement.
- Soft-tissue protection — A barrier shields your gums and lips from the whitening gel.
- Gel application — A professional-strength hydrogen peroxide gel is applied to your teeth in controlled cycles.
- Rinse and reveal — We remove the gel, rinse, and compare your new shade to where you started.
Patients across Burlington, Oakville, Hamilton, and the Halton Region choose in-office whitening when they want a brighter smile for a special event or simply prefer the convenience of a single appointment.
Take-Home Whitening Kits
Prefer to whiten at your own pace? We offer custom take-home kits that include:
- Custom-fitted trays — Moulded from impressions of your teeth for even gel distribution and minimal gum contact
- Professional-grade gel — Stronger than anything available in stores, yet gentle enough for daily use over one to two weeks
- Detailed instructions — Our team walks you through wear times and best practices
Take-home kits are also a great way to maintain results after an in-office session.
Am I a Candidate for Teeth Whitening?
Professional whitening works best on natural tooth enamel with extrinsic (surface) staining. During your consultation at our Burlington practice, we will evaluate:
- Current oral health — Cavities and gum disease should be treated first
- Type of discolouration — Intrinsic stains (from medications or trauma) may respond better to porcelain veneers or other cosmetic treatments
- Existing restorations — Crowns, bonding, and fillings do not whiten and may need to be replaced to match your new shade
Maintaining Your Brighter Smile
Results can last six months to a year or longer with good habits. Our Burlington dental team recommends:
- Brushing twice daily and flossing once daily
- Rinsing with water after consuming staining foods or drinks
- Attending regular general dentistry cleanings — our guided biofilm therapy removes plaque and surface stains efficiently
- Using your custom take-home trays for periodic touch-ups
Is Teeth Whitening Safe?
Yes. When performed or supervised by a dental professional, teeth whitening is one of the safest cosmetic procedures available. Temporary sensitivity is the most common side effect and typically resolves within a day or two. At Dentistry at LaSalle, we tailor gel concentrations and application times to minimise discomfort while maximising results.
Frequently Asked Questions About Teeth Whitening
How white will my teeth get?
Results vary by individual, but most patients see an improvement of three to eight shades with professional treatment. During your consultation we will give you a realistic preview of what to expect.
Does whitening damage enamel?
No. Professional whitening gels are designed to penetrate enamel safely without causing structural harm. Our team monitors concentration levels and exposure times to protect your teeth.
Can I whiten if I have sensitive teeth?
Often, yes. We can adjust the gel strength and recommend desensitising products to use before and after treatment. Let our Burlington team know about your sensitivity during your consultation so we can customise your plan.
How does professional whitening compare to store-bought strips?
Store-bought strips use a lower concentration of peroxide and a one-size-fits-all tray, which can lead to uneven results and gum irritation. Professional whitening delivers faster, more uniform improvement with clinical oversight for safety.
