How Can An Abscessed Tooth Be Treated?

I have had an acute abcess in my lower left teeth for some time now. It swells up, i take antibiotics, it goes down, theb we repeat every couple months. A while back, a tiny hole appeared right below it between my gum and lip, some infection leaked out, it hurt this terrible burning pain, and the next day the pain was gone, but the hole was/is HUGE.Now remember, i have bad teeth, i need them all pulled, but i am absolutely HORRIFIED of dentists. Anyway, its been bothering me all day, abd tonight i found a brand new hole right next to the older one...its still small, but im now bearing the horrible burning..almost like its stretching. Please tell me what these are, if they can be treated and how, and that im not going to die.
