What is the whitening gel strength in the CleverWhite Teeth Whitening kit?
CleverWhite’s proprietary whitening gel contains 6% Hydrogen Peroxide (equivalent to 18% Carbamide Peroxide) which shortens the time required for effective whitening. Our research shows this is the most effective strength for home use whitening. Higher concentrations are not recommended as they can lead to gum irritation and tooth sensitivity.
