@nobsroutines: Replying to @Jess Fluoride toothpaste was a 1950s breakthrough, and most of what's on the shelf hasn't changed since. Fluoride still works, but the science didn't stop in 1955. The 70s brought nano hydroxyapatite (out of NASA research, then Japan), the mineral your teeth are made of. NOBS toothpaste tablets are made with it, a remineralizing agent that rebuilds your enamel while you brush. #fluoride #toothpaste #teeth #hydroxyapatite #toothpastetablets
