(butting in here LOL) My hubby had his first dental appt when he went into the Army in 1965. Teeth and gums were excellent. He's 62.5 and has never had a cavity or ANYTHING. I hate him LOL His good teeth can't be genes either. Both of his parents had terrible teeth. His mom who lived to 96 had dentures and his dad had bad teeth. We have never lived in a city with floride either. Good limey well water. LOLL
