<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have this little white cut on my lower front gums in my mouth that hurts really bad. What is it? It s very painful to eat. I have great teeth so I know it shouldn t be from cleaning. Its a pretty deep cut and I havent fell or cut my self in the mouth. Thanks  <response>: Thanks for your query, I have gone through your query. The possible causes of the cut could be a tooth brush injury or from food particles. Nothing to worry about it, you can take topical anesthetic and analgesics like Anabel gel. Apply 3-4 times daily before food. If the cut does not heal in 7 days then consult an oral physician and get it ruled out from other lesions. I hope my answer will help you, take care.
