Different Types Of Teeth Staining
Why Are My Teeth Stained?
With white teeth and a nice smile so important to both your appearance and just how others perceive you, it is interesting to understand just what has stained your teeth or why.
Here are two basic types of teeth staining – Intrinsic and Extrinsic Stains
This is primarily caused by the foods we eat and whatever we drink, red wines, colas, coffee and tea are the main liquid culprits, while some foods, especially acidic based ones can all cause yellowing or staining of the tooth enamel. Another main cause is smoking, especially unfiltered cigarettes. Certain medications along with bacterial infections can also cause the problem
Extrinsic stains basically colour the external enamel and can in most cases be removed by bleach based teeth whitening which can be carried out either by your Dental surgeon, or by investing in a home teeth whitening kit
Intrinsic Stains are more difficult to remove, usually caused by injury to the teeth, infections, vitamin deficiencies and other health problems. Some medications can also cause intrinsic stains, this includes the antibiotic tetracycline that is often given to children.
The stains caused by tetracycline in particular are quite difficult to remove and tend to be a brown or even grey in colour.
The type of whitening treatment required will depend on the actual type of staining; those stains that are intrinsic are less likely to be removed by bleaching and will require other cosmetic treatments such as veneers or overlays. If you have these types of staining, it’s best to consult your dental surgeon to discuss your options.
