Just as the title, our lil guy has what looks like black tartar on his far back teeth on his bottom jaw. I mean it really just looks like dirt or something, not alot just a few specks on the bottom of the tooth near the gum. He is eating fine, altho refusing dubia(which he did love before), but eats crix, supers, silkworms, hormworms, sometimes eats reptiworms and a lil salad every day. I just dont know if there are health concerns I should know of, or watch out for with these symtoms. The spots have been there for a lil over a week, not spreading or anything. Any advice or info would be great. Thx.
