Can you learn to stop nibbling your nails?


Believe it or not, you can nail your nibbling habit — and the sooner, the better. Experts have linked nail-biting to bruxism, or the grinding or clenching of teeth. Bruxism can cause jaw problems, facial pain, and extremely sensitive teeth.

Here are a few key ways to break the habit. You also can try these techniques with youngsters. Just remember to praise them for their efforts.

  • Trim rough, ragged nails and file them smooth. Broken nails can be very tempting to nibble.

  • Apply a bitter-tasting polish or liquid to nails.

  • Learn to do something else when you feel the urge to chew. For example, make fists for a minute or so. But be careful not to swap one bad habit for another. Chewing on a pencil can lead to mouth injury, too!
