Extrinsic Teeth Stains 

      An extrinsic tooth stain is staining on the surface of the tooth. It occurs when staining particles, such as pigmented residue from food or drink, a build-up in the film of protein that covers the tooth enamel. Extrinsic tooth stains are typically caused by tobacco use or by regularly drinking coffee and tea, wine or cola drinks. This type of tooth stain responds well to regular dental cleaning and brushing the teeth with whitening toothpaste.
      

What is an Extrinsic Teeth Stains


Stains on teeth are generally of two varieties, extrinsic and intrinsic. ... Extrinsic stains generally occur on the surface of a tooth, and typically result from consumption of foods and beverages which contain pigments, such as coffee, tea, caramel coloring. Extrinsic stains can also result from smoking (tar stain).

What causes of Extrinsic Teeth Stains
