question: I am 29 years old, I broke my teeth through an accident 18 yrs ago and have since intermittently felt a build up of pus in my upper gum above my two front teeth. Since, I have not replaced the teeth since the accident, i am just wondering if I made a terrible mistake because the area in my outer upper gum is very tender and hurts so bad at certain times of the year. I hope sb can give me some useful advice.
