Teeth sandblasting
You should remember that before whitening teeth, dentists recommend teeth sanding. It is a preparatory treatment, though in a lot of cases, it decisively brightens your smile.
It is like this because the colour of our teeth results not only from the colour of the enamel and dentine but also all sort of residues and scale.
The removal of scale and residues brightens teeth to a certain extent, however, first of all it makes the whitening agents work more effectively and evenly.
