Hello, Im 17, about to be 18 and a few months ago I felt a small bump on the upper left side of my gum. It was and still is on the spot where my tooth should be coming in. Now there is another one not so far from it. I have been readingdifferent post and I'm a little scared that it might be an abscess or some form of cancer. It doesn't hurt at all. I have not gone to any doctor about it though.

An abscess would hurt and you would probably have a fever or other signs. Visit your dentist.
