Lip biting is a common habit. During consultations some clients will tell us that they bite or lick their lips when they are nervous or concentrating on something and wonder how we can help.
WHY DO WE BITE OUR LIPS?
Sometimes you can bite your lip by accident, just like you do with your tongue and then you may use your tongue and teeth to play with the sore spot.
This is usually harmless. However, if this habit continues for long enough lip biting can on occasion, cause injury.
