Wick just had his 9th molar spur filing yesterday actually. http://www.instagram.com/p/Bi7m9JnAFtt/
… Spur filing is quite common. In some circumstances, it’s common because unfortunately the rabbit isn’t eating as much hay as it should, so the teeth grow out more than they should
In other circumstances, it’s the result of genetics, where perhaps the rabbit’s teeth aren’t aligned correctly, so they are unable to evenly wear out all their teeth.
Based on my experience, I think the best way to know if it’s diet versus genetics is to have a teeth filing done, then monitor to see if it comes back. If it does, despite lots of hay consumption and chewing, then it’s more likely to be something that needs to be done routinely.
If your vet is experienced and your rabbit is generally healthy, going under for the filing shouldnt be too dangerous. Some things that may occur can be slight pain or mouth soreness afterwards, in which case giving a shot of pain medication after the operation is common.
“Giving more hay than usual” isn’t a good phrase, because ideally they should have unlimited hay anyways. So unless you aren’t giving them unlimited access to a lot of hay now, which you should be, this most likely will not help at this point. Do they eat a lot of hay? How much do you give them? How’s the rest of their diet?
