Yes! I have had the same thing happen and have been advised to take my prescription prior to having dental work.
This happened to me and they said it was due to a blue liquid burning it and it was an accident , I’m upset I’m 15 years old and have a talent show later today :/
I've been having spots on upper lip problem for 4 years now! It sucks, don't know what to do! People look at me and it makes me feel terrible! How can I remove them for good?
