What is tooth whitening?

Tooth whitening can be a very effective way of lightening the natural colour of your teeth without removing any of the tooth surface. It cannot make a complete colour change, but it may lighten the existing shade.

Teeth Whitening- Want a whiter smile? Your main options are at-home and in-office bleaching. At-home teeth whitening involves custom-made dental trays filled with hydrogen peroxide gel that you can use at home. For in-office bleaching, your dentist will combine hydrogen peroxide gel with a light source to speed up the whitening process.
