Yes, they loose their baby teeth just like we do. I have found 5 of my 4yr old's teeth. If it was brown and icky looking, like he had a cavity, you could have the vet look at his teeth just to make sure they aren't bothering him or he doesn't have anymore possible cavities. At 4yrs old though he should have had his teeth already checked on by a vet.
