Teeth bleaching products contain peroxide, which at higher concentrations can cause sensitive teeth. Not only that, but because individual teeth respond to bleaching at different rates, there’s no guarantee your teeth will get whiter faster.

Fact

With at-home and OTC teeth whitening products, you run the risk of selecting or using an inferior product, incorrectly applying it, or overusing it. Overusing a teeth whitening product or using an inferior product with low pH can result in enamel damage (one of the causes of sensitive teeth).

Myth
