<human>: 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?
<bot>: 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.
