I’ve tried looking this up and can’t find the anatomy for these little flaps in my mouth. On the floor of my mouth that are essentially“split” into 2. One side is very red and inflamed and he’s been hurting the last couple days. When I lift up the red inflamed flap it loop like a white sore at the tip. I can’t remember if these flaps have always been there but like I said I can’t find anyone else on the internet with these. What is this? Is this normal? Should I call my dentist? I’m scared of oral cancer. I’m 26 and a non smoker.
