When I was a kid, I believed that when you got older your teeth fell out. I knew so many older people had false teeth that the assumption I made was that they must just fall out as you get older, like when you lose your baby teeth when you're a kid. Let me tell you I was VERY relieved to learn that regular brushing, flossing and trips to the dentist would keep my teeth in place.
