The CAO Group’s Sheer White!™ consists of thin, flexible films plus 20% carbamide peroxide gel. Easily applied, stays where placed, and whitens teeth fast. The thin flexible moldable material closely adapts to every surface holding the whitening gel where it belongs – against the tooth surface. No leaking or wash out of gel. No slipping or sliding of the film. Comfortable, long–lasting wear. Even, effective whitening. Easier. Faster. Better.
