What is the sign of biting the tongue when eating?

Many people always bite their lips or tongue when eating. This may be due to poor rest, lack of mental concentration, or a phenomenon caused by nerve failure to control muscles normally. It is recommended not to worry too much and clean up oral hygiene at the same time. Eating and biting the tongue is not a disease, nor is it a sign. It is recommended that patients chew slowly to reduce the situation of eating and biting the tongue.
