Tooth stains can be embarrassing as they may be seen as a sign that someone doesn’t look after their teeth properly, but there’s more to staining than meets the eye.
There are two main types of tooth stain: stains that appear on the surface of the tooth (extrinsic), and staining that appears within the structure of the tooth (intrinsic).
Extrinsic stains can be caused by:
Intrinsic stains can be caused by:
Staining and discolouration are slightly different. Discolouration is caused by a filling bleeding within the tooth, causing it to change colour; or by the nerve dying inside the tooth and bleeding into the root canal. Discolouration can also be the result of erosion and wear of the tooth.
As extrinsic stains affect a tooth’s surface, they are relatively simple to remove with a thorough oral hygiene routine of brushing, flossing and rinsing. Plaque and debris that cause this staining can also be removed professionally by dentists.
Although whitening toothpastes can help to remove stains, they do not stay in contact with teeth for long enough to lighten their colour. LISTERINE® Stay White can prevent the build up of stains while reducing the build up of plaque bacteria which can lead to discoloured teeth.
