Is it normal to eat your toenails?
Unusual.Less common, but harmless
It happens, but eating toenails isn’t a common habit. A one-off usually isn’t a big deal, though it’s best not to make a meal of it.
Some people bite or chew their nails and may swallow bits without thinking; deliberately eating toenails is less common. Toenails can be dirty or sharp, so swallowing them isn’t a great habit to encourage.
If you find yourself doing it often or feel unable to stop, it may help to notice what tends to trigger it and find something else to do with your hands or mouth. That’s not something to be ashamed of—just a habit you can work on.
