Teeth can become discoloured by stains on the surface of the tooth. There are three types of tooth discoloration:

Extrinsic: It occurs when the outer layer of the tooth is stained. Coffee, wine, cola, smoking causes extrinsic stains.

Intrinsic: It occurs when the inner surface of the tooth darkens or gets a yellow tint. You can get this if:

  • You had too much exposure to fluoride during early childhood.
  • You had trauma in a permanent tooth, and internal bleeding discoloured the tooth.
  • Your mother used tetracycline antibiotics during the second half of pregnancy.
  • The condition called dentinogenesis imperfect causes grey or purple discolorations.

Age Related: It is a combination of intrinsic and extrinsic factors. Dentin naturally yellows over time, and the enamel that covers the teeth gets thinner as you age.  Foods and smoking can also stain teeth.

Symptoms and Diagnosis

Its symptoms include stains on the enamel. They can vary from yellow tints or brown spots and pits.

No special tests are needed for the diagnosis of teeth stain. A dentist can diagnose tooth discoloration by looking at the teeth.

Few tooth discoloration can be removed with professional cleaning such as stains caused by coffee. But many stains are permanent which can be whitened with a bleaching gel. If the discoloration is severe, then a crown or veneer may be required to cover it.

Prevention of Tooth Stain

  • Brush your teeth after every meal to prevent stain.
  • Rinse your mouth after having wine, coffee or other drinks or foods that can stain the teeth.
  • Regularly cleanings by a dentist will also help to remove surface stains.
