What it is
Professional teeth whitening uses a peroxide-based gel — typically hydrogen peroxide or carbamide peroxide at concentrations higher than over-the-counter products — to break down surface and sub-surface staining. In-office protocols accelerate the process with a controlled application and sometimes a light to activate the gel.
How we approach it
We start with a candid evaluation of stain etiology and starting shade. Surface staining (coffee, tea, wine, tobacco) responds well to peroxide. Tetracycline staining and severe fluorosis often do not respond completely and may require cosmetic dentistry. Restorations in the smile zone — crowns, veneers, composite — do not change shade with whitening; we discuss what that means for your final smile uniformity.
For patients with active dental decay or untreated periodontal disease, dental care comes first. Whitening is cosmetic, not therapeutic.
What to expect
In-office protocol: 60–90 minutes including isolation of soft tissue, gel application, and timed cycles. Result is visible at the appointment.
Take-home tray protocol: custom trays fitted at the office; daily wear for a defined period (typically 30–60 minutes per day for one to two weeks); gradual shade change over the course.
Transient tooth sensitivity for 24–48 hours is common after in-office whitening. Avoid coffee, tea, red wine, and other staining beverages for 48 hours after each treatment to allow the porous post-treatment enamel to seal.
Candidacy
Best for surface and age-related staining in patients with healthy teeth and gums. Not for tetracycline staining, active dental disease, significant smile-zone restorations, or pregnancy.
