Um I noticed that on the gumline just under my lower tooth I have red spots. I was brushingmy teeth and it felt a little sensitive. I looked in the mirror and found very small red spots. They are not bumps. It looks like a hickey- That's the only way to describe it. It is slightly tender. If it is swollen, it is so slight that I can't tell. I ate some hot food today. Could that be a gum type burn? I am also taking a muscle relaxer, and an anti inflamatory. Could it be an allergic reaction? The only reason why I would say no to the reaction is because it is only in a small area next to 2 teeth. I can't find this description or picture on the internet. I am a little worried of what this could be.
