I think I have one I've look at some information about abseccess's on the internet and it's exactly what I'm experiecing. The gum is swollen about one of my teeth and a white dot is appearing [and getting larger]. Has anyone had this before? I'm going out of town tomorrow and I'm scared that it will get really bad. Is there anything I can do for it? I'm not going to a dentist, ever, so I'm guessing it will get alot worse.
