Tooth Color
Abnormalities in tooth color can result from a number of causes.

Food pigments may stain the teeth, although these changes should be temporary. Smoking can also discolor the teeth.

Excess fluoride intake can cause a range of color changes, from a lacy, chalky white discoloration to severe brown staining of the teeth. (Refer to Chapter 6: Fluoride for more information).

Abnormalities in tooth color can be caused by the following:

  • Nerve necrosis secondary to trauma
  • Severe caries
  • Tetracycline use by a pregnant mother in the second half of pregnancy or by a child early in life
  • Oral iron supplementation
  • Poor oral hygiene
  • Medical problems
 
 
Excess fluoride intake can result in a chalky white or severe brown discoloration of the teeth.
 
Root death from trauma or severe caries causes a grayish discoloration of the teeth.
 
Food pigments, smoking, oral iron supplements, and poor oral hygiene can all discolor the teeth.
 
Tooth discoloration should be evaluated by a dentist to determine the likely cause and if treatment or prevention exists.
