Tooth whitening brightens teeth, but some worry it may damage tooth enamel. Well, researchers have found that home bleaching does not damage enamel.
Published in the Journal of the American Dental Association, this study examined the effects of 10% carbamide peroxide (the active ingredient in many home teeth whiteners) on human tooth enamel.
They found that teeth bleaching does not effect enamel wear. (However, dentin is susceptible to erosion from tooth whitening products.)
This is excellent news, dispelling any notions that whitening yellow teeth through cosmetic dentistry can be bad for one’s oral health.
