It sounds harmless; you don't have access to a can opener, scissors or any other sharp object to open a tricky bag of chips or a stubborn bottle top. So, you use your teeth. And why not? They get the job done.
Not so fast.

Habits like chomping on a pencil or using your teeth to rip off tags from your new clothes don't seem that life threatening; but the outside pressure can cause your teeth to chip, crack, and if the pressure is strong enough, break.
