My bunny has dental disease, and it’s progressing quickly…

My little 4 year old (will be 5 in March) has dental disease. Initially it started out with just a couple molars on the left side growing spurs. We were able to go in every couple months for dental trims, and then it started to become more frequent. He had gotten weepy eye on his left side and some of the tooth roots were causing a small abscess behind his left eye. He was put on oral antibiotics for a bit and that seemed to help the weepy eye.

They had also informed us that several other teeth started to have their roots growing longer than they’re supposed to. Fast forward to his recent dental this month, and they said it’s not just two teeth that had spurs this time, but now 9 teeth with spurs.

I know they’ve brought up teeth removal, which would cause more abscesses, and then the teeth either above or below the teeth would have to be removed etc…. I just don’t think I could put my boy through all that. It feels at that point more for me than it is for him. We are still playing by ear since he still seems happy and plays and eats etc, but I also feel so sad because the idea of putting my baby to sleep hurts.. I’m also 23, so spending this kind of money isn’t easy.. but I would spend every penny and go broke for that bunny. He’s my everything. I don’t know any input is welcome, I just don’t wanna feel like I’m doing the wrong thing if it comes down to putting him to sleep.. this is my first time with this, please be kind
