Also known as onchophagia, the habit of nail biting is one of the so-called "nervous habits" that can be triggered by stress, excitement, or boredom. Approximately half of all kids between the ages of ten and 18 have been nail biters at one time or another. Experts say that about 30 percent of children and 15 percent of adults are nail biters, however, most people stop chewing their nails by the time they turn 30.
Here are four dental and general reasons to stop biting your nails:
- IT'S UNSANITARY: Your nails harbor bacteria and germs, and are almost twice as dirty as fingers.
- IT WEARS DOWN YOUR TEETH: Gnawing your nails can put added stress on your teeth, which can lead to crooked teeth.
- IT CAN DELAY YOUR ORTHODONTIC TREATMENT: For those of our patients wearing braces, nail biting puts additional pressure on teeth and weakens roots.
- IT COSTS: It has been estimated that up to $4,000 in extra dental bills can build up over a lifetime.
