I don't know what kind of vet you go to, but $800 for a monthly dental seems a little excessive. And it may not even be something that becomes a problem if you are able to manage it with her diet. Hay will help with tooth wear. The thicker more fiberous stems are good, as well as some chew sticks. If you can get some untreated apple, willow branches, etc, these can help with keeping those sharp points worn down. All rabbits can be prone to developing sharp points, some have more of a problem than others, but most rabbits it can be managed with a good diet that promotes even tooth wear.
If you do happen to have a dental done, it doesn't necessarily mean it is going to have to be a monthly thing, and you may want to look around for a different vet, that is still good with rabbits, but has more reasonable rates.
