Stained teeth may make an individual feel self-conscious about the way they look. They may also refrain from smiling for the same reason. As a workaround, people resort to oral care procedures like teeth whitening. Studies also show that about 67% of individuals in the country have tried some type of procedure, including at-home kits, to whiten their teeth. However, the constant use of these products may do more harm than good, and here are five reasons why. Loss of tooth enamel The enamel is a shell that protects the teeth from any damage. However, the constant use of teeth-whitening products may lead to tooth enamel erosion. The lack of this outer tooth covering may make one more susceptible to tooth decay. And since at-home whitening products are not as effective as the ones available at the dentist, people may overuse them, leading to severe enamel erosion. Uneven whitening A person who whitens their teeth at home without proper guidance might find that the process is not completed evenly. These products may also be unable to get between the teeth because of their inferior quality. Following the process, the individual might notice patches or stains on some parts of the teeth, while other regions look brighter and stand out.
