Sheer White! 20% Carbamide Peroxide Teeth Whitening Films go on easy, stay where you put them, and help whiten teeth fast.

Sheer White is the most significant advance in teeth whitening in nearly a decade. The thin flexible moldable material closely adapts to every surface holding the whitening gel where it belongs - against the tooth surface.

There is no leaking or wash out of gel and no slipping or sliding of the film, enabling a more comfortable, long-lasting wear. The films provide even and effective whitening. (To convert carbamide peroxide to its hydrogen peroxide equivalent, divide by 2.8)
