I quit chewing snuff about a month ago. I have been using nicotine gum to ease the transition. In the past couple of months, I've noticed bumps inside my lower lip. They are small yet visible, and I can feel them with my finger. Also, my lip is a little swollen around the line that separates the bottom of the bottom lip from my face. I also notice the slight swelling in the mirror -- it is puffed out. I'm supposed to go to the dentist in June. Is this something that should be looked at sooner?
