About 12 years ago, I had someone hit me in the face with a metal contraption, like a grid. My lower teeth (3) went through my bottom lip. Those three teeth were damaged. My lower gum was a mess. In retrospect, I probably should have gone to the doctor, but did not. I worked over my lip. My gum healed, sortof. The teeth are still not right. My lip was visibly healed, a year later, but I still feel lumps in it. Not a fun process.
