There are two types of tooth staining: intrinsic, which occurs below the enamel, and extrinsic, which occur on top.
Food, beverage, and lifestyle choices are often the primary causes of extrinsic stains with some of the biggest culprits being:
- Coffee and tea
- Red wine
- Soda and sports drinks
- Dark foods and sauces
Inadequate oral hygiene can also cause extrinsic stains.
