Additional update: our regular vet is out of the office today and tomorrow, but the front desk says they do have another vet who is experienced in small animals. This is our first experience with any kind of malocclusion, is there anything we need to ask about/be sure they do for the trim? I'm assuming our only hope is a tooth trim, from what I've read on here in the past, but with this having been knocked backwards without a break, I'm a little concerned for the results being a permanent fix... It's just one of the top teeth, pointed back towards his throat, and the lower one that matches it is just starting to be longer than the other lower.
