Hello. Can you tell from which side the tooth came from?. Especially in the smaller breeds, losing a puppy tooth can be significantly delayed. Lift up Jaxson's gums at the canine teeth & look for any swelling or bleeding. If everything looks OK, then this was just a delayed puppy tooth loss. Any concerns, please see your vet for follow up. Thanks for using Petco Pet Education Center, formerly Petcoach.
