<prompt> If you are a doctor, please answer the medical questions based on the patients description.Dear Doctor , 2 years ago I had a pain in my jaw. I have consulted a Dentist and he prescribed me a medicine.After taking that medicine my mouth began to close and it got infection Pus near to the molar teeth after taking some treatment it recovered but my underlips are still unconscious. Please advice me...  <response>: Hi, You have OT mentioned the type of treatment undertaken which corrected your problem. If it was a surgical extraction in the 2nd or third molar area, it may have caused some compressiondamage to the inferior alveolar nerve because of which you are feeling this numbness in your underlips region. The nerve usually heals on its own. You can take supplements to enhance the regeneration though which can be prescribed by a Dentist.
