These days the usage of teeth-whitening kits for the instant smile makeover is rising rapidly. Some experts claim that the usage of these teeth-whitening kits may cause permanent damage. According to British Academy of Cosmetic Dentistry (BACD), the high levels of hydrogen peroxide dye in teeth-whitening kits leads to chemical burns and exacerbates gum disease. These over-the-counter kits contain more hydrogen peroxide solution in them (some teeth whitening kits are 250 times more concentrated than the legal limit of 0.1 percent concentration) causing tooth loss and aggravating gum disease. It is said that one has to consult a dentist before going to use these whitening-kits so as to avoid unnecessary dental risks.
