In the early 90s, I had an abscess make an opening in the front of my gums and start draining. It seems that the
metal point in my root canal caused the
abscess and an endodontist did a second root canal, removed the metal and used gumma percha and it was fine. Now it’s 2018 and I have a soreness beneath my nose and I thought it was from clenching my teeth while I sleep. That was until I just poked my finger up there and there is a swelling about the size of a raisin and it is painful.
