Hi there, My jawbone is poking through my lower right side gum. I am reasonably certain it is my jaw, since it is the underside of my jaw and I would be pretty impressed it a tooth were growing there. A little background - Wisdom teeth removed long ago. No recent surgeries or extractions in the area. No weird medications that I am on. It just felt like the bone slowly began to poke through or perhaps the gum receeded. What would cause this?
