We caution our patients about the dangers of nail biting on your teeth. Nail biting is one of the so-called “nervous habits” that can be triggered by stress, excitement, or boredom. Experts say that about thirty percent of children and forty-five percent of teenagers are nail biters. However, most will stop chewing their nails by the time they turn thirty.
Here are four dental and general reasons to stop biting your nails:
- It’s unsanitary. Your nails harbor bacteria and germs, and they are almost twice as dirty as your fingers. Moreover, swallowing dirty nails can lead to stomach problems.
- It wears down your teeth. Biting your nails can put added stress on your pearly whites, which can lead to crooked teeth.
- It can delay your orthodontic treatment. For those wearing braces, nail biting puts additional pressure on and weakens roots.
- It can cost you, literally. Our friends at the Academy of General Dentistry estimate up to $4,000 in extra dental bills over a lifetime.
We recommend the following to kick your nail biting habit:
- Keep your nails trimmed short; you’ll have less of a nail to bite.
- Coat your nails with bitter-tasting nail polish.
- Ask us about obtaining a mouth guard, which can help prevent nail biting.
- Put a rubber band around your wrist and snap it whenever you get the urge to bite your nails.
- Think about when and why you chew your nails. Whether you are nervous or bored, understanding the triggers can help you find the solution to stop.
- Reduce stress in your life. Find a relaxing activity to partake in or say no to certain activities in your busy life. Nail biting often occurs when a person is stressed.
If none of these remedies work for your child, please ask your provider for more options. Our team is happy to help you or your child find a solution to the nail biting during your next appointment. Request an appointment online at either of our two convenient locations.
