Steroid: I would rx a steroid for a canker sore. Either a gel or if it is bad, an oral rx. The key is catching it early.

I had my teeth cleaned three days ago at the dentist. I never had a cold sore before, I have a canker sore now but I accidentally popped it when I touched it, it bled and now it looks like a small pimple. Is it possible it's my primary outbreak?
