Teeth-whitening kits available on online marketplaces have been found to contain illegally high levels of hydrogen peroxide which can burn gums and cause dental damage.

An investigation carried out by Which? tested 36 kits and 21 of them exceeded the legal amount of the chemical for home use while one had 300 times too much of the active ingredient.
