Staining is classified into two types:
- Extrinsic Staining
- Intrinsic Staining
Extrinsic Staining, as the name implies its caused by extrinsic agents like tea, coffee, mouthwashes, tobacco use, any restorative procedures such silver restorations (amalgam) on the outer surface of the teeth.
They can be treated with a mixture of a specific powder and a toothpaste in the dental clinic.
After removal of the stains, brush your teeth twice a day with flossing to prevent recurrence.
Intrinsic Staining are a series of stains which affects the internal layers of the tooth and could be caused by:
- Changes in the structure or thickness of the dental hard tissues.
- Incorporation of pigments during tooth development. For example, the teeth of the fetus or child taking tetracycline drugs will stain their teeth bluish-brown (Figure 1).
- Diffusion of pigments into hard tissues after development. For example, Root canal medicament may stain the teeth gray.
Treatment approaches depends on the case but may involve a mixture of a specific acid and powder, bleaching, veneers and crowns, all of which can done in dental clinic.
Don’t forget to brush your teeth & floss!
