So I went to the dentist for a filling yesterday and he managed to catch my lip with the heat curing light. I don't really blame him as I have a very small mouth and they struggle with everything, but it's left an attractive blister right at the corner of my mouth. All the google hits for a blister on mouth (even when I include terms like 'caused by dentist' or 'after a filling') are about cold sores or ulcers, and it's clearly not that.
So anyone ever had a blister on their lip that wasn't a cold sore? Should I be putting anything on it, like Germolene? Or just leaving it alone? My skin doesn't always heal great and I'm vaguely concerned about the potential for infection.
