Fox News: Charcoal Teeth Whitening Products Do Not Have ADA Seal Of Acceptance.

Fox News (8/15) reports that dentists and other medical professionals are warning against using a DIY teeth whitening method that “involves smearing a charcoal-derived black mixture on teeth.” The method has become more popular since the posting of a YouTube video, that has been watched more than 1.5 million times. The article reports that dentists say using this DIY method “may lead to enamel deterioration and tooth erosion,” noting “the American Dental Association has currently not evaluated or approved any charcoal teeth whitening products.”

MouthHealthy.org provides additional information on teeth whitening. In addition, several whitening toothpastes and a whitening product have the ADA Seal of Acceptance.
