To use this whitening kit, a person places a strip on their teeth for 30 minutes with the company’s Advanced Seal technology holding it in place. Crest writes that this helps the strip mold to the teeth. Users can talk and drink during treatment.

This product is reportedly safe for tooth enamel and sensitive gums.
