Yesterday I notice Roxy, who just turned 1, was playing with something. It was her bottom kanin tooth and one of the teeth next to it, that fell out of her mouth...the two teeth were still attached to each other. Is it possible that it was two of her baby teeth? I looked in her mouth and I didn't see any new teeth growing in, its just her gums. The teeth that feel out looked brown and hollow. I am really concerned should I call the vet?
