Gum trauma causes painful white blister?

About 6 days ago I was brushing my teeth and I jammed the plastic edge of my toothbrush hard against my lower right-hand outside gum. There wasn't any blood, but in the days since, some sort of white blister has developed and is sensitive to the touch. It looks like a short (inch-long) line along my gum where the toothbrush hit. Any ideas how long this will take to go away, and if there's anything I can do to speed that up? Thanks!
