Hello, for some time now I have been unable to chew on the right side of my mouth. I have not been brushing my teeth and I understand that is my fault, but I am 18 now, I remember back in elementary school, the top of my gums swelled up and I couldn t chew when they did. But today I noticed that on the side I am unable to chew on, also where I had swollen gums too, there is like an indent in the back with my molars. Is that gum recession? Thank you for any info you could provide. -Jacob
