Researchers found the active ingredient in tooth whiteners can eat away at the material covering the sensitive structures of the tooth. - TODAYShow
In three experiments, researchers found the active ingredient in tooth whiteners, hydrogen peroxide, can eat away at dentin, the material right below the protective enamel and covering the sensitive structures of the tooth, according to the reports presented at the annual meeting of the American Society for Biochemistry and Molecular Biology.can penetrate through enamel, said Kelly Keenan, a co-author on all three studies and an associate professor at Stockton University.
Apparently, the hydrogen peroxide causes the collagen in dentin to break down into small fragments, the New Jersey researcher said. What the researchers don’t know yet is whether dentin damaged in this way can regenerate, Keenan allowed.Dr. Lee Gause, a dental professor, wasn't surprised to see hydrogen peroxide would have an impact on dentin.
