# Tooth Discoloration Types
> Discoloration has different causes, and the cause decides which options help. A simple guide.

## Guides
- [Extrinsic Stains on the Tooth Surface](https://types-of-tooth-discoloration.fagyny.workers.dev/extrinsic-stains/): Extrinsic stains are pigments that collect on the outer surface of the teeth, usually from drinks, food, tobacco and plaque film.
- [Intrinsic Stains From Inside the Tooth](https://types-of-tooth-discoloration.fagyny.workers.dev/intrinsic-stains/): Intrinsic stains form within the tooth structure rather than on its surface, so brushing and routine cleaning rarely change them.
- [Age-Related Darkening of Teeth](https://types-of-tooth-discoloration.fagyny.workers.dev/age-related-darkening/): Age related darkening happens because enamel gradually thins and the yellower dentin beneath becomes more visible, while years of surface stains add to the.
- [A Single Darkened Tooth](https://types-of-tooth-discoloration.fagyny.workers.dev/trauma-darkened-tooth/): A trauma darkened tooth is one tooth that changes color while its neighbors stay the same, often after a knock, a deep filling, or a long-standing internal.
- [Getting a Diagnosis](https://types-of-tooth-discoloration.fagyny.workers.dev/dentist-diagnosis-discoloration/): A dentist diagnosis for discoloration starts with where the color sits, how long it has been there, and whether the tooth is healthy underneath.
