Does anybody know at roughly what age a puppy has replaced all of its baby teeth with adult ones? One of my two, Jesse, has just lost a tooth. She's about 10 months old now so I would of thought all of her teeth would be adult ones? She ate a piece of carrot that fell on the floor so I was thinking this might have caused it? I hope it wasn't an adult one and I'm just being paranoid!
At 10 months my pup still has 4 baby teeth to loose (upper I3s, and canines). You may want to find a calm moment to take a peek in her mouth, lift the lip so you can get a good view of the gums, you may find there are still a few teeth hiding, or that may have been the last one. Unless she is having serious tooth decay which is unlikely given her age, or had an injury, losing an adult tooth isn't a major concern.
Most vets will remove any remaining baby teeth when they spay/neuter a dog.
