Types of Teeth Discoloration
Teeth discoloration can be broadly categorized into two main types: extrinsic and intrinsic discoloration.
Extrinsic Discoloration :
Extrinsic discoloration occurs when the outer layer of the tooth, known as the enamel, becomes stained or discolored.
Common causes of extrinsic discoloration include:
- Consumption of dark-colored foods and beverages such as coffee, tea, and red wine.
- Tobacco use, including smoking and chewing tobacco.
- Poor oral hygiene practices leading to the buildup of plaque and tartar on the teeth.
Intrinsic Discoloration :
Intrinsic discoloration occurs when the inner structure of the tooth,
known as the dentin, becomes discolored or darkened.
Causes of intrinsic discoloration include:
- Exposure to certain medications, such as tetracycline antibiotics, during tooth development.
- Trauma or injury to the teeth, which can cause internal bleeding and discoloration.
- Genetic factors that influence the natural color of the teeth.
