The deciduous (baby) teeth usually fall out by about 6-7 months of age for most dogs and cats. Most veterinary dentists advise that if not gone by that age that it is ideal if they are carefully surgically excised as soon as possible after 6-7 months old so as to minimize damage to the permanent adult teeth that can occur if the deciduous teeth remain.
Two teeth should never occupy the same space. Retained teeth cause overcrowding, pain, malocclusion (misaligned bite), and increased risk of periodontal disease.
Most veterinarians have seen older dogs who still have deciduous teeth that “look” okay, but we have to realize that without xrays damage to the related adult teeth and surrounding bone can’t be evaluated. And, we certainly can’t appreciate what discomfort or pain may be present.
