About 2 weeks ago, the gums at the back of my teeth is really swollen. It doesn t hurt, but it s uncomfortable. Recently, about a few days ago, a teeth is starting to appear at the back, right at the swollen part. The swollen gums are not so swollen now, but it s a little bit swollen. Today, the swollen part is tearing away. The rest of the gums are still intact, but the swollen part seems to be peeling away from my teeth. Is it normal?
