Crest Whitestrips Supreme provides custom tray-level whitening with 14% hydrogen peroxide - the highest concentration available in a professionally dispensed take-home whitening product.
The strips are ready-made so they can be used right away with no dental impressions being required and are portable enough to be used anywhere, at any time during the day.
Crest Whitestrips have gel already added to them so they deliver a consistent, controlled dose each time. (To convert hydrogen peroxide to its carbamide peroxide equivalent, multiply by 2.8)
