You can fix it right once and be done with it or you can fool around with it. If you decide to fool around with it you'll almost surely be replacing that rim sometime in the future.
Ok, my comment was not even about the area around the nipples, it was about the dent in the rim. It was to be used as a filler as seagullplayer said. Just a filler.
