There are basically two major types of tooth discoloration or staining: internal (intrinsic), where the stain is built in the structure of the tooth, and external (extrinsic), where the tooth is affected from the outside.

Extrinsic

The extrinsic staining happens because of microscopic pits, defects and fissures in the outer surface of the tooth’s outer layer (the enamel). The substances that stain the enamel layer arise from multiple sources: certain beverages and foods (red wine, tea and coffee in particular), tobacco, chromogenic oral bacteria, and a long list of medication. Also, if a person does not maintain a proper dental hygiene, the accumulation of plaque increase the staining. What is more interesting is that even the ingredients of certain dental cleaning products that can cause staining. Some mouthwashes contain chlorhexidine, which after long-term use, can cause dental staining (on composite resin, acrylic ad porcelain restorations).

Saliva also plays an important role in removing food debris and lowering the acidity and bacteria levels in your mouth. With lower saliva levels you will experience a dry mouth. This can arise from a lot of causes such as large obstructions, radiation treatments, chemotherapy and a lot of medications.
