A mis start should not stuff the ring gear. They are stronger than that. But you should be able to see the damage if you remove the starter. Look at the engaging side (starter side) of the teeth on the gear. You should see some obvious, significant wear on them - usually bevelled on the outside (starter) edge. If they do not look obviously damaged, they probably are OK. Usually if that is the issue you will find intermittent start performance - depending which part of the gear is engaging - ie the first bit to wear gets worse quicker than the rest - so you end up with dead spots on the gear, and other bits that work OK.
I have /had several high mileage cars, never replaced a ring gear.
