Teeth whitening ‘is usually effective because of hydrogen peroxide’
The process of teeth whitening is usually effective because of the presence of hydrogen peroxide within the formulas used.
This according to Dr Thomas P Connelly, a cosmetic dentist who told the Huffington Post that the bleaching agent can "absolutely" help when it comes to brightening smiles.
He explained that professionals who use them will carry out a test on patients first to make sure they are not intolerant of hydrogen peroxide, in the same way a hairdresser would do a strand test on hair before colouring it.
"If you experience no side effects, then using hydrogen peroxide (in moderation) to help whiten teeth is probably OK," Dr Connelly commented.
The expert added that as hydrogen peroxide uses its effectiveness when stored, it is a good idea to visit a professional when having teeth whitened rather than a practice where the substance has been sitting on a shelf for two years.
Earlier this month, New York-based orthodontist Dr Jacqueline Fulop Goodling told MyGloss.com that professional teeth whitening treatments are regulated and safe, as well as being more high-quality than DIY kits.
