I have bilateral swelling of the gums above my first and second molars. The swelling does not start where the gum meets the teeth, but slightly above it. I have no tooth pain, but the gums are sore and the swelling/lump feels rock hard. It started on the right side yesterday, but now the left side is slightly swollen. It started as just redness, and now white lesions that look like canker sores have appeared on both sides.
I'm going to a doctor tomorrow, but I'm curious what this could be and am worried.
