That actually surprises me as well. I’m impressed.
However what you presented are statistics for American citizens.
If you were to include the roughly 3 percent of people living in the USA that are undocumented, that pushes it below the 51 percent “most people” number. those 12 million people may or may not have a valid passport.
As a side point, the actual number of undocumented residents is hard to pin down. 3 percent is an estimate, but still a significant number.
I grew up on well water. I still have well water as an adult. Finally swapping to a prescription grade flouride toothpaste is the only thing that has gotten my cavities in check. It’s been a struggle my entire life.
Brushing twice a day did not matter. No sweets did not matter. I have basically no candy or sweet drink habits at all.
I can directly attribute my lifetime of cavity problems to non flourinated water. My dentist agrees.
This is going to wreck America’s health.
