Dental veneers mostly refer to whitening veneers, and in fact there is no such treatment clinically. Long-term use may affect tooth enamel, tooth sensitivity and so on. Whitening stickers mainly contain peroxide bleaching substances, such as hydrogen peroxide, urea peroxide, etc., which release hydrogen peroxide with smaller molecular weight and penetrate the enamel and dentin more easily, thus playing the role of bleaching. The enamel protects the inner dentin, and the use of whitening stickers may damage the enamel and cause damage to the surface of the teeth. Additionally using whitening veneers may irritate the pulp and cause tooth hypersensitivity. Whether to use dental veneers, it is recommended to visit the hospital in time, under the guidance of the doctor to give targeted treatment or treatment.
