Will a dog’s double row of teeth fall out on its own?

A dog’s double row of teeth generally will not fall out on its own. It occurs when the adult teeth erupt normally but the baby teeth fail to shed, often linked to calcium deficiency or a congenital defect, and can be familial.

The double row easily traps dirt and breeds bacteria, leading to stomatitis and tartar that harm oral health. It is usually advised to have the extra teeth extracted at a vet after adulthood; if you prefer not to, brush the dog’s teeth daily to protect its mouth.
