I woke up and my left lower gum area where my last tooth is, is swollen and hurts terribly. There seems to be a cut on the on the gum (I cant really see it), but I think its between the gum and the last tooth. I rinsing my mouth with mouthwash and today started with salt water and peroxide. I am 30 year old female. It cant be my wisdom teeth because I had them removed when I was 12. I cant bite down all of the way without felling the pain.  My jaw is hurting a little as well as tender on bottom when I touch the bottom of my face.
