Use this with your favorite whitening strips.

This teeth whitening light works best when whitening gel or strips are applied to the teeth first, then shined on (both are sold separate). The light can be tucked just behind the lips so it rests comfortably and shines on the front of your teeth. The light can be used for short whitening sessions of just 10 minutes or up to 45+ minutes, depending on the instructions provided by the teeth whitening gel or strips you use.
