Whitening That Works for You
There's no shortage of whitening products available. Most produce modest results at best. Professional whitening at Stouffville Dental Arts uses GLO Science technology to deliver brightness that's consistent, safe, and calibrated to what actually looks right on you.
We approach whitening the way we approach everything else here: foundation first. If there are decay or gum issues that need attention, we address those before any cosmetic treatment begins.

Results You'll Notice
Whitening treatments applied by a dental professional are monitored from start to finish. We check that your teeth and gums are healthy before beginning, apply the gel precisely, and ensure the process is controlled so you don't experience unnecessary sensitivity.
Safe and Controlled
Professional whitening is applied under clinical supervision. Concentration, timing, and application are all managed carefully, which means effective results without the uneven coverage and sensitivity that come with unsupervised treatments.


Tailored to You
We consider the natural tone of your teeth, your skin tone, and what you want to achieve. The goal is a result that looks right for you specifically, not a uniform shade applied the same way to every patient.
Find Out What Your Plan Covers

What Is GLO Science Whitening?
GLO Science uses a combination of warming heat and guided light technology to activate a professional-grade whitening gel. This accelerates the process and promotes even coverage across the full surface of each tooth, producing results that are consistent, controlled, and noticeably brighter than what at-home products can achieve.
Who Is a Good Candidate?
Whitening works on natural tooth enamel only. Before booking, it's worth knowing:
- Crowns, veneers, bonding, and fillings will not respond to whitening gel. If you have restorations on visible front teeth, we'll discuss what that means for your results
- Active decay or gum disease needs to be treated before whitening can proceed
- A recent cleaning produces better whitening results. If you're overdue, we'll recommend scheduling one first
- Patients with significant existing sensitivity should flag this at their consultation so we can plan accordingly

Whitening vs. Veneers
The right choice depends on what you're trying to fix:
- Whitening changes colour only. It does not affect the shape, size, or surface texture of your teeth.
- If chips, cracks, or uneven shape are also a concern, veneers address all of those things at once
- In some cases, whitening first makes sense before committing to veneers, so the veneer shade can be matched to a brighter baseline
- If you're weighing both options, bring it up at your consultation, and we'll give you a straightforward recommendation

What to Expect During Your Smile Whitening Visit
Before Your Appointment
We review your oral health to confirm whitening is appropriate at this time. If a cleaning or any other treatment is needed first, we'll let you know and get that scheduled.
During Your Appointment
Your gums are protected before the whitening gel is applied. The GLO Science system is then activated using its warming and light technology. The process takes about an hour. Most patients find it comfortable throughout.
After Your Appointment
Results are visible immediately. Some patients experience mild sensitivity in the hours following treatment; this is normal and temporary. Avoid dark-coloured foods and drinks such as coffee, tea, and red wine for the first 24 to 48 hours while the enamel settles.
Maintaining Your Results
Results typically last 6 month to 1-year, depending on diet and oral hygiene habits. Regular cleanings and limiting staining foods and drinks help preserve brightness over time.

Frequently Asked Questions
How is professional whitening different from whitening strips or toothpaste?
Over-the-counter products contain a fraction of the whitening concentration used in professional treatments, which limits how much change they can produce. Professional whitening delivers faster, more consistent results under controlled conditions, with gum protection that at-home products don't provide.
Can I whiten my teeth if I'm pregnant or breastfeeding?
We recommend waiting until after pregnancy and breastfeeding. Speak with your physician if you have questions about timing.
How does GLO Science compare to other whitening systems?
GLO Science uses warming heat and light activation to accelerate results and promote even coverage. It's designed to be effective and comfortable, with less post-treatment sensitivity than some other in-office systems.
Is there anything I should avoid after whitening?
For the first 24 to 48 hours, avoid coffee, tea, red wine, berries, and tobacco. Your enamel is more susceptible to staining in this window. Normal habits can resume after that.
Why doesn't whitening work on crowns or veneers?
Whitening gel works by penetrating natural tooth enamel to break down stain molecules. It has no effect on porcelain, composite resin, or other restorative materials.
Can whitening damage my enamel?
Professional whitening applied correctly and at appropriate intervals does not damage enamel. Overuse of unsupervised at-home products is where enamel damage becomes a concern.
How many shades whiter will my teeth get?
Results vary depending on the natural colour of your teeth and the degree of staining. We'll give you a realistic expectation at your consultation based on what we see.
Will whitening make my teeth sensitive?
Some patients experience mild, temporary sensitivity after treatment, resolving within 24 to 48 hours. If you already have sensitive teeth, let us know at your consultation so we can factor that in.
Is professional whitening safe?
Yes. Applied by a trained dental professional, whitening is safe and well-tolerated. Concentration and application are controlled throughout to protect your gums and enamel.
How long do whitening results last?
Typically, one to three years, depending on diet and oral hygiene. Regular cleanings and limiting exposure to coffee, tea, red wine, and tobacco help extend them.
