My rabbit has been ill for about 6 weeks now, keeps twisting his head round, grinding his teeth, going off some of his food, drinking loads and very lethargic, he has his teeth trimmed every 5 weeks so we thought maybe it was his teeth but they seemed ok so we had an xray done and it showed uneven tooth roots. The vet didn't think this was the problem due to the strange head twisting he was doing but because he was in pain he was given a steroid injection to try and control the pain. However since he has come home he has just been laying on the sofa all day, he is drinking loads and he is letting me put my finger in his mouth and rub his gums and he seems to really enjoy it. Would the uneven tooth roots cause this and also is their anything else I can try.
