## Guides
- [Enamel Thins With Age](https://why-teeth-turn-yellow.pages.dev/enamel-thins-with-age/): Enamel thins with age through years of chewing, brushing, acid exposure and grinding, and a thinner layer lets the yellowish dentin beneath show more.
- [When Dentin Shows Through](https://why-teeth-turn-yellow.pages.dev/dentin-shows-through/): Dentin is the naturally yellowish layer under the enamel, and when the enamel is thin, worn or translucent, dentin shows through and teeth look yellower.
- [Surface Stains vs Deep Stains](https://why-teeth-turn-yellow.pages.dev/surface-vs-deep-stains/): Surface stains sit on the outside of the tooth and come from things like tea, coffee, wine and tobacco, while deep stains form within the tooth and have other.
- [Genetics and Tooth Color](https://why-teeth-turn-yellow.pages.dev/genetics-tooth-color/): Genetics and tooth color are closely linked, because the thickness and translucency of your enamel and the shade of the dentin beneath it are largely inherited.
- [Medications and Tooth Color](https://why-teeth-turn-yellow.pages.dev/medications-tooth-color/): Medications and tooth color can be connected: a few medicines and some mouthwashes are known to cause staining, and certain antibiotics taken while teeth are.
