I hear you. My first house must have been fancier because it was $25000.00.
As I said, I have been lucky that I haven't had much in the line of tooth problems. I was raised until 15 in upper, upper New York State. When I had my first dental appointment in Vermont the first thing the dentist said was, you aren't from around here are you? You must be from a place that had fluoride in the water. I had been and it lasted for a life time. My dads teeth were terrible and he had dentures by the time he was 50. My mother had beautiful teeth that she practically wore out from brushing, but, at the same time only ate the soft parts of all food. As you stated they were wonderful on the outside, but, inside they were just fillings. She could hardly walk past a magnet without pulling toward it.
Both my children have had no cavities in their lives. My wife had just shells with fillings, but, she was from Cananada, where, I'm sure
@JenniferS will verify, teeth are not considered essential.
