I'm in the same boat: 28, no cavities (knock on wood!). I also have only one wisdom tooth, and it's thankfully wedged against my back molar where it's not a nuisance. My parents have awful teeth with plenty of fillings on both sides (my dad got full dentures a few years ago), and my dentist has in fact told me that he doesn't know where I get my dental health from, but to be thankful it's not from my parents.I do not loathe the dentist, as I've not had the bad experiences. I'm 53 years old and have never had a cavity (knock on wood). I had my wisdom teeth out, which is when I discovered how great codeine is (does it take away the pain? Nope, but you don't care...stab you in the eye with a fork? Don't care...). My dad has terrible teeth and was on full dentures by the time he was 50, wondering why he hadn't done that 20 years earlier. My mom's are pretty good though, and I had a great-great aunt on her side who was once got a root canal when she was about 90. I asked why on earth she was going through that at her age, why not just pull the tooth, and she said believe it or not, she still had all of her original teeth. She didn't have a lot of long-term goals left in life, but dying with all her teeth was one. I guess I got that tooth gene.
