Ok, so Bronx is now 8 months old and he's pretty much lost all his baby teeth...except for the two "fangs" (not sure of the proper name). The adult ones fully came in but the baby ones haven't, so he has a total of 4 "fangs". We've given him different kinds of hard treats to maybe loosen them, but no go. Do I need to make an appointment at the Vet. to have them removed or will they eventually fall off? Is it bad for him to just keep them?
