Are whitening strips bad for you?


The majority of whitening strips are safe to use; however, if you use whitening strips that contain chlorine dioxide, you could destroy the enamel on your teeth. Chlorine dioxide is the same acid that is used to disinfect swimming pools. It whitens teeth by eating away at the surface of the enamel.

When used correctly, it can not only ensure the safety of teeth and gums, but also achieve the whitening effect. This is countless. The experiment confirmed it. However, the wearing period should be calculated in weeks, and it will take at least two weeks to have a more obvious effect.
