I take it you mean a tooth on the starter ring gear? I have successfully welded a 'false tooth' onto ring gears in the past. I built it up with the mig welder and reshaped it with a narrow grinding disc and a file. Twice I've done this in situ (on diesel cars so lots of torque required to turn them over) and it hasn't failed yet. Just throwing another option out there :thumbsup:
