On the back of my bottom incisors and 1st molars I have a weird growth. It's attached to each tooth individually, but grows into one mass. It's like I suck gum to the back of my tooth and let it harden. After it's grown fully in it starts to push the bottom of my mouth (Under my tongue) out. It grows over my gums and as it gets bigger it really starts to hurt. I don't have a dentist and I really just want to know what is going on. I've had this my whole life practically and I'm 17 now.
