"Is this yours?" my dad asks my mom and me.
My mom and I do a quick tongue-check of our teeth. "Not mine," we both say.
"O.K.," says my dad and puts it into an old film canister for safekeeping. "I'll just hold onto it."
Now the weird thing isn't that my dad found a tooth on the floor. With three people 60 and over, there's bound to be a crown or a bridge or some kind of artificial tooth lying around. No, the weird thing is that no one seemed surprised that there was a tooth on the floor that didn't happen to belong to anyone.
