Thanks for that.
Since posting I've casually interviewed several people and think I see a pattern:
1) People who see their dentist regularly, but who are not body aware, get drilled and filled.
2) People who are body aware and who care about their well being, but who take advice and procedure with a grain of salt sometimes get drilled and filled - sometimes their bodies heal.
3) People who neither care nor are aware and who don't see their dentists very often tend to have serious decay issues.
Interesting - the things they don't teach you in school....
