Quick answer
Professional teeth whitening uses pharmaceutical-grade bleaching agents at concentrations not available in retail products. Custom-fitted trays made in our on-site Calgary lab hold the gel in even contact with every tooth surface, producing results typically 4 to 8 shades brighter over a 2-week at-home regimen. Whitening works on natural tooth enamel only and does not affect the shade of crowns, veneers, or denture teeth. A brief consultation confirms candidacy and rules out sensitivity concerns before any treatment begins.
Why Professional Whitening Works Better
Why Professional Whitening Makes a Difference
Over-the-counter whitening strips, toothpastes, and trays use low-concentration peroxide to limit safety concerns with unsupervised use. The result is minimal brightening at best, and the effects fade quickly because the gel cannot maintain consistent contact with each tooth surface.
Professional whitening uses pharmaceutical-grade bleaching agents at concentrations not available in retail products. Treatment is applied precisely, and because the trays are custom-fitted, the gel maintains full, even contact across every tooth surface - producing results that are noticeably brighter, typically 4 to 8 shades lighter, over a 2-week at-home regimen.
Custom At-Home Whitening Trays
We take impressions of your teeth and fabricate custom trays in our on-site Calgary lab. The trays are designed to hold whitening gel against every tooth surface evenly, with no slipping or pooling. You wear them at home for 30 to 60 minutes per day over a 2-week period.
The trays are reusable - for future touch-ups, you only need to order refill gel. Most patients maintain their results with a touch-up once every 12 to 18 months.
Who Is a Good Candidate?
- Healthy natural teeth with no major restorations on front teeth
- Yellowing or darkening from coffee, tea, wine, or aging
- No severe sensitivity issues (manageable with lower concentrations if present)
- Realistic expectations - whitening works on natural enamel only
Whitening does not affect the shade of denture teeth. If you are considering new complete or partial dentures, whiten your natural teeth first so Steve can match the denture teeth to your preferred shade.

Frequently Asked Questions
Common questions about professional teeth whitening in Calgary.
-
Is professional teeth whitening safe?
Yes. Professional whitening using peroxide-based gels is safe when applied correctly. Some patients experience temporary sensitivity during or after treatment. Steve will assess your teeth beforehand and recommend the appropriate concentration and application schedule to minimize sensitivity.
-
How long do professional whitening results last?
With good maintenance, professional whitening results typically last 1 to 2 years. Results last longer if you limit staining foods and beverages such as coffee, tea, and red wine, and avoid tobacco. Touch-up treatments using your original custom trays with refill gel are simple and economical.
-
Will whitening work on my crowns, veneers, or dentures?
No. Whitening agents only affect natural tooth enamel. Crowns, veneers, bonding, and denture teeth will not change colour. If you have significant restorations on your front teeth, whitening may create a visible shade mismatch. Steve will advise you on this during the consultation before any treatment begins.
-
Can I whiten if I have sensitive teeth?
In many cases, yes. Lower-concentration gels, desensitizing pre-treatments, and shorter application times can accommodate sensitive teeth. Steve will customize the whitening approach based on your sensitivity level and the current condition of your enamel.
-
Should I whiten before or after getting new dentures?
Always whiten first. Denture teeth are matched to your natural tooth shade at the time of fabrication. If you whiten after your dentures are made, the denture teeth will appear darker than your brightened natural teeth. Whiten to your desired shade first, then Steve can match your new dentures to that shade. Learn more about complete and partial dentures in Calgary.
