Hey I'm 18 years old and I'm only sexually active with one girl. A couple of months ago I've noticed a tiny bump on the base of my left cheek. It kinda bothered me whenever I closed my mouth but I thought nothing of it. I'm worry now because It swelled to the point I can't close my mouth. I recently lost the dentist I had and can't find another that accepts my insurance. I have pictures so it can give a better visual. Please help me should I be worried?
