Will the scratch in the enamel of my front tooth cause it to rot or discolor or will the enamel repair itself? What should I do?

I was eating breakfast the other day accidentally bit down on the edge of one of the fork tines. It scratched my front, top, right tooth on the very end. Now I can feel a rough/sharpish spot on my tooth with my tongue or fingernail. It isn't visible so I don't need to post a picture, and it's not really causing discomfort unless I push my fingernail into it. But it does concern me since I've always had great teeth and can't afford discoloration for my job as a salesman.
