Whatever progress it may provide, I am certain that dentists and dentists' associations will slowly and surely entomb any process that reduces the sum of their individual annual incomes. I believe Adam Smith called it "the invisible hand" (w/o explicitly noting that the "invisible boot" is jammed into the "invisible customers"' collective asses).
It's so sad that most dentists optimise for billable revenue, even at the detriment of long term patient health. Fillings for example always degrade and need repairs after X years. Drilling and filling even the smallest cavity puts that teeth on a lifetime progression to bigger and bigger fillings, eventually a root canal, eventually an implant. Cavities, on the other hand can be arrested (stopped), and if small can…
Unfortunately high fluoride toothpastes require an RX.
