Whitening gel — what works, what doesn't.
There are four kinds of whitening gel on the market. Here's how they differ, which one we use at UNO, and how to pick what's right for your case.
Hydrogen peroxide (in-office strength).
What Philips Zoom uses for in-office whitening — 25–40% concentration, applied with cheek and gum protection, activated under a light. Fastest shade change. Not safe for at-home use because of the gum exposure risk.
Carbamide peroxide (at-home strength).
Breaks down slowly into hydrogen peroxide. 10–22% concentrations are typical for prescription home trays. Slower than in-office but more gentle on sensitivity. What we send home with our custom-tray patients.
Drugstore (low concentration).
1–10% peroxide in strips and over-the-counter trays. Slow, modest results. Fine for maintenance but won't deliver a real shade change.
Activated charcoal & natural whiteners.
These don't whiten — they scrub. Charcoal is abrasive and can damage enamel over time. We don't recommend them.
Common questions.
Is in-office whitening worth it?
For most patients, yes — 4–6 shades in 60 minutes versus 2 weeks of nightly trays. Often combined with trays for maintenance afterwards.
Will whitening damage my enamel?
Properly applied, no. The gel oxidizes stain molecules; it doesn't dissolve enamel.
What about sensitivity?
Common, temporary, and manageable. We use desensitizing pre-treatment and recommend potassium nitrate toothpaste during whitening.
