I have an area of my gums, upper left side, right beside a crown, where it swelled up. It's been swelled up for about two weeks now. There's no pain in or around the crown or the swollen gums, little discomfort, just a little swollen area about the size of a small pea, that's covering about half of the tooth with the crown. As far as I know it wasn't brought on by eating hot food.
