Warning: HSA, dentists warn against popular DIY teeth whitening kit

The Beautiful-Cold Light Teeth Whitening Kit, contains 4% hydrogen peroxide, well above the 0.1% limit allowed for home use without a prescription.

Regulations on hydrogen peroxide are strict because high concentrations of hydrogen peroxide, a chemical agent that is commonly used in teeth whitening products, is potentially corrosive, and an assessment of the cause of teeth discolouration has to be made before the whitening can be done.

High concentration of hydrogen peroxide may worsen pre-existing teeth and gum problems such as gingivitis, periodontal disease and gingival lesions.
