(HealthDay News) -- Nail biting is a common way to cope with anxiety or boredom, but it's an unhealthy habit.
Here's what the Nemours Foundation has to say about the dangers of nail biting:
Biting your nails prevents them from doing their job, from helping to pick up small objects to scratching an itch.
Biting nails can lead to tiny openings in the skin, which can trigger an infection.
Germs that lurk beneath your nails can enter your mouth while you're biting them.
