There would have been many generational differences between your diet and dental hygiene and those of your parents when they were growing up.Because my parents shared the same diet and dental hygiene practices. The only difference was they didn't get fluoride when they were young.?
But they were, and they are. My own family is proof. Apart from my children, I had many contempories when I was growing up who had excellent teeth - no fluoride!Because good diet and dental hygiene alone were not enough to prevent tooth decay in previous generations that grew up without fluoride.?
