# Cavity Stages Notes
> Decay develops over time. Seeing the stages helps explain what dentists watch. Written for everyday readers, with honest limits.

## Guides
- [White Spot Lesions](https://stages-of-tooth-decay.pages.dev/white-spot-lesions/): White spot lesions are chalky, opaque patches on tooth enamel that often signal early mineral loss.
- [Enamel Decay: The Basics](https://stages-of-tooth-decay.pages.dev/enamel-decay-stage/): The enamel decay stage is when acid has dissolved minerals from the outer layer of a tooth but has not yet broken through into the softer dentin.
- [Dentin Decay: A Practical Guide](https://stages-of-tooth-decay.pages.dev/dentin-decay-stage/): The dentin decay stage begins when decay passes through enamel into the softer layer beneath, where it can spread faster and start to cause sensitivity.
- [When Decay Reaches the Pulp](https://stages-of-tooth-decay.pages.dev/pulp-involvement/): Pulp involvement means decay has moved past the enamel and dentin and reached the soft tissue at the center of the tooth, where the nerve and blood vessels sit.
- [Early Detection at Checkups](https://stages-of-tooth-decay.pages.dev/early-detection-checkups/): Early detection checkups matter because decay in its first stages usually causes no pain, so a tooth can look and feel fine while a problem develops.
