Tooth whitening is a non-invasive solution for mild to moderately discoloured teeth. While tooth whitening is considered a relatively safe treatment, there is still some concerns in relation to tooth whitening services provided by non-dentist, for e.g. at beauty salons.
As dictated by the prevailing regulations from the relevant authorities, teeth whitening products containing more than 0.1% Hydrogen Peroxide are only available via dentists. Hydrogen Peroxide is the chemical ingredient that whitens the teeth.
Many beauty salons claim that they use non-Peroxide whitening gels. The majority of these
use Sodium Perborate to ‘whiten’ teeth instead.
