1) Don’t go to an ER vet for this. This isn’t an emergency and ER the vet will likely not even trim them, just tell you to follow-up with your regular vet. ER vets are for immediately threatening situations (not eating, not drinking, lethargic behavior).
2) This is what you should do. Make an appt for this coming week to have a dental exam and trimming (if the vet feels it’s necessary).
3) I have heard of some people trimming teeth themselves. I personally wouldn’t do this b/c it’s very easy to crack the tooth lengthwise if you trim the wrong way. Leave it to the professionals… That’s my thought.
4) For anterior teeth, hay consumption isn’t going to be the fix. Hay eating is most beneficial for maintaining the back molars b/c it requires a grinding motion to break it down. If the front teeth are misaligned, there isn’t a lot that can be done except for regular trimming, or possibly removal of the teeth. Chewing on wood blocks can be helpful, but only to a certain degree. Misaligned teeth will continue to be misaligned and overgrow regardless of whether the rabbit is chewing on toys.
And just like horses and their water… you can give a rabbit a block of wood, but you can’t make them chew ;o)
