reconditioning gears and sliders

I have some pretty worn gears and synchro sliders and I tried grinding the dog teeth so that they are somewhat pointy again (vs. rounded as before).
Turned out ok but could this be a problem in the sense of that the dog teeth are too far back now? Didn't grind of a lot but removed some material.

@A/J, what do you think?

Here are some pics:



before:



after (the one tooth in the middle needs some more work obviously):
