<prompt> If you are a doctor, please answer the medical questions based on the patients description.My mother is having a problem in her mouth .Age:47. The part of inside mouth i.e inner cheek comes between the teeth and create a cut. This happened always and it looks like a mark. We consulted doctor and they said that due to age, the muscle of face becomes loose and it goes in between the teeth. Can you please provide me a solution for this ?  <response>: Hi, Thank you for the query. Cheek bite is a most common problem among every individual. Cause for it varies, may be due to a sharp margins formed due to attrition of the teeth in aging , due habits like tobacco chewing. Usually if left unattended it may lead to formation of cancerous lesion due to repeated trauma. Selective grinding in case of sharp or irregularity in teeth can be done. Another possibility is lack of proper occlusion when closing the mouth or biting or chewing the food. If it is because of improper occlusion then it requires correction of occlusion. Your dentist can diagnose the reason for the cheek bite and treat accordingly. Hope the information will help you.
