I have a white hole at the connecting line between my gum and lower lip.  The area around it is swollen and tender.  It also looks like it may be a cut.  It is very uncomfortable, especially if I try to pull my cheek out to look at it.  I  have no idea what it is.  Any ideas?
Thanks for using Chat Doctor. Read your query. The lesion described at the junction if the lower lip suggests the formation of an authors ulcer, which is very painful initially. I would advise you to apply McCoppin / mucosal on the affected area two or three times a day. It should reduce by a week. For pain, take a paracetamol. Avoid spicy food and reduce stress levels. If still persistent, consult your local dentist. Hope this was helpful. Thanks and regards.
