There’s a new term floating around called “bleachorexia,” which is given to people with unrealistic standards of teeth whitening and therefore excessively bleach their teeth. With all things in excess, too much bleaching can damage gums and wear away the enamel on teeth. While this is not by any means a medical term, several dentists say they have had patients come in with gum or tooth damage due to too much bleaching or have requested several bleaching sessions.
Many dentists blame the easy availability of at-home bleaching kits, toothpastes, and mouth rinses for spiking the obsession for abnormally white teeth. Loose bleaching trays can scrap and cut gums, making them irritated and inflamed and could even cause the gums recede. Too much bleaching can wear away the enamel and make them look blueish, which only makes “bleachorexics” want to bleach more and more.
Dentists suggest limiting professional bleaching to at least every six months to keep your teeth not only looking healthy, but staying healthy.
