Intrinsic and extrinsic stains on teeth can be caused by factors such as ageing, smoking, poor dental hygiene and regular consumption of certain food like coffee and wine. The teeth can appear discoloured or yellowish as a result.
When scaling and polishing are unable to remove the stains, your doctor may suggest teeth whitening as a solution to lighten the colour of your teeth. You can opt to be treated in the clinic or take home a custom-made tray for your teeth to carry out the whitening process at home.
