Is Whitening Teeth with Hydrogen Peroxide Harmful for Tooth Enamel?
When whitening the teeth with hydrogen peroxide many people wonder how often one can whiten teeth. Is the repetitive use of hydrogen peroxide harmful? While everyone desires a perfectly white smile, they certainly don’t want to be causing damage to the teeth in achieving a desirable smile. Studies are revealing that hydrogen peroxide may or may not be harmful to the teeth; it all depends on its concentration levels. Researchers have discovered that hydrogen peroxide does not affect the surface of tooth enamel even with repetitive use. Dentists using hydrogen peroxide that consists of 38 percent hydrogen peroxide had noted no changes in the structure of the enamel after using repeated whitening applications. In contrast, there are studies that suggest that hydrogen peroxide, in high concentrations, can change the enamel of one’s teeth by increasing the actual porosity of the teeth. Further, the use of hydrogen peroxide in higher concentrations than 38 percent have been found to result i
