# Dairy and Teeth > Dairy supplies calcium and has a tooth-friendly reputation. What it does, and what to watch in sweetened versions. ## Guides - [Calcium in Dairy](https://dairy-and-dental-health.loresiwa.workers.dev/calcium-in-dairy/): Calcium in dairy is one reason milk, cheese and plain yogurt are usually seen as tooth-friendlier foods than sugary snacks. - [Casein and Enamel](https://dairy-and-dental-health.loresiwa.workers.dev/casein-and-enamel/): Casein is the main protein in milk, and casein and enamel are discussed together because milk proteins interact with tooth surfaces in laboratory settings. - [Sweetened Yogurt Caution](https://dairy-and-dental-health.loresiwa.workers.dev/sweetened-yogurt-caution/): Sweetened yogurt caution comes down to added sugar: plain yogurt is a reasonable food for teeth, but fruit, dessert and flavored versions can carry as much. - [Lactose-Free Options: Tips and Cautions](https://dairy-and-dental-health.loresiwa.workers.dev/lactose-free-options/): Lactose-free options are ordinary dairy with the lactose already broken down, so they bring much the same minerals and protein as regular dairy. - [Plant Milks and Teeth](https://dairy-and-dental-health.loresiwa.workers.dev/plant-milks-teeth/): Plant milks are a mixed group, so there is no single answer on plant milks teeth. ## About - [About Dairy and Teeth](https://dairy-and-dental-health.loresiwa.workers.dev/about/): not medical advice, how the site is funded and how guides are made ## Optional - [RSS feed](https://dairy-and-dental-health.loresiwa.workers.dev/feed.xml)
