Abnormal tooth color is any color other than the white to yellowish-white of normal teeth.

Discolored teeth; Tooth discoloration; Tooth pigmentation

Many different things can cause tooth discoloration. The change in color may affect the entire tooth, or just appear as spots or lines in the tooth enamel.

Your genes influence your tooth color. Other things that can affect tooth color include:

• Congenital diseases
• Environmental factors
• Infections

Inherited diseases may affect the thickness of enamel or the calcium or protein content of the enamel, which can cause color changes. Metabolic diseases may cause changes in tooth color and shape.

Drugs and medications either taken by the mother while pregnant or by the child during the time of tooth development can cause changes in both the color and hardness of the enamel.

• Antibiotic tetracycline use before age 8
• Eating or drinking items that temporarily stain the teeth, such as tea or coffee
• Genetic defects that affect the tooth enamel, such as dentinogenesis and amelogenesis
• High fever at an age when teeth are forming
• Poor oral hygiene
• Porphyria
• Severe neonatal jaundice
• Too much fluoride from environmental sources (natural high water fluoride levels) or overuse of fluoride rinses, toothpaste, and fluoride supplements
