Well thank you, you just answered my question. I was looking for the answer, "they will grow back". My Gerbil was the victim of an accident when my 4yr old paniced, thought she was going to get out of the play wooden box (with lid) that we use to let her play while I'm cleaning her cage. He dropped the lid on her head. She bled alot. I quickly cleaned her up, applied ice to the nose and left eye region and took her to the hospital. They said they could do X-ray but it would be useless because there really isn't anything you can do. The Vet said her teeth were okay but while giving atibiotics I have been able to take a closer look and noticed her bottom teeth are chipped straight across leaving her unable to nibble on the food. I've been giving her peas ( I peel them for her) cooked carrots, cooked corn and I boil the nuts to soften them. She likes the peas mostly but I'm not sure what a rounded gerbil diet consists of? Oh, she'll eat oats too.
