# Fasting and Teeth
> Eating windows change saliva and snacking patterns. A look at how fasting routines interact with mouth care.

## Guides
- [Fasting and Dry Mouth](https://intermittent-fasting-and-teeth.pages.dev/fasting-dry-mouth/): A dry mouth during a fast is common, and it is often linked to drinking less, mouth breathing or certain medicines rather than fasting alone.
- [Fewer Snacks, Fewer Acid Attacks](https://intermittent-fasting-and-teeth.pages.dev/eating-window-fewer-snacks/): Every time sugar or acid reaches your teeth, the mouth needs time to recover, so frequency matters as much as quantity.
- [Black Coffee While Fasting](https://intermittent-fasting-and-teeth.pages.dev/black-coffee-fasting-teeth/): Plain black coffee contains no sugar, so it is gentler on teeth than sweetened versions, but it is still acidic, can stain and can leave the mouth drier.
- [Brushing During Fasting](https://intermittent-fasting-and-teeth.pages.dev/brushing-during-fasting/): Brushing during fasting is a question of timing and habit, not a reason to skip cleaning.
- [Fasting and Breath](https://intermittent-fasting-and-teeth.pages.dev/fasting-breath/): Fasting breath is a common complaint, and the cause is often a drier mouth and bacteria on the tongue rather than anything serious.
