Missing one tooth in flywheel

Our 78 Aspen Street Kit Car was having starting problems, so my son put in a new starter. He found the old one (original had a number of sheared teeth. He also noticed one broken "tooth" on the flywheel (could be more, but not visible). Anyway, with the new starter the car starts up like a champ--no clatters like before. My question is "If there is just one tooth missing on the flywheel, will that be a significant problem?" Thank you.
