I have a real problem with my gerbil's teeth. He's 2 and a half, but this has only been a problem in the last few months. I noticed that he seems to be growing extra teeth on the lower set of teeth, I know they are new because they grow through white..but surely if he isn't actually losing any teeth - he shouldn't be growing more? He seems very uncomfortable and keeps clawing in his mouth and grinding. I don't know what to do, since he keeps on growing new teeth, some fall out and grow again! Its also chipping his top teeth and making the gums bleed.. Can anyone give me any help/advice?? and is it worth going to a vet to put him under anaesthetic to sort the teeth out?.. because I know gerbils dont always survive this. Help please!
