Over the counter (OTC) teeth whitening strips are not only inferior to options such as tray whitening, they can actually be harmful to your teeth. Whitening strips rely on acids to remove surface stains and must be used with greater frequency to achieve results similar to those offered by other at-home solutions. However, it is less the ingredients of these strips than the frequency at which they must be used that is harmful to your teeth. Constant exposure to acidic substances can destroy tooth enamel and, once destroyed, enamel cannot come back, which can open the door for issues such as tooth sensitivity and cavities. While OTC whitening strips may seem like a cost-effective option, their dangers far outweigh their benefits.
