Will Teeth Whitening or XpresSmile harm the teeth?
No. Research shows that orange juice is more corrosive to the enamel than LED teeth whitening. Because the teeth are exposed to the gel for less than an hour, the enamel is not affected. However, constant whitening with over-the-counter strips or trays will soften enamel so it is important to use the XpresSmile Enamel Boosters after any type of whitening.
