In the last 24 hours one sore formed in the upper right hand section of my gums, in the last 2 hours another sore formed in the front of my mouth on the gums. Both are white and stick out instead of in like a canker sore. They are about a half a cent in diameter. Both have a low intensity constant burning feeling to them. I was wondering what it could be and if I should seek treatment or just wait for them to disappear.
