Crest Whitestrips® Tooth Whitening. The flexible, virtually
invisible strip holds the whitening ingredient against the
teeth long enough to get at stains beneath the surface.
The most recent addition to the Crest Whitening Strip family, the Supreme
version uses 14% hydrogen peroxide - versus the 6.5% used in Professional
Whitestrips, and the 5.3% used in Crest Whitestrips. Includes 84 Tooth
Whitening Strips.
