Tooth staining is a natural occurrence that happens over time due to what you eat, drink and whether you smoke.
Teeth whitening is a process where discoloured teeth are ‘whitened’ to a lighter shade. When done by a trained dentist it is a safe and effective way to remove stains and lighten the shade of your teeth. The dentist will take care to ensure the whitening is carried out to achieve a ‘whiteness’ which will suit your natural colouring and age.
It is not effective on dental restorations such as amalgam fillings, or porcelain crowns.
