I have no idea about the scientific veracity of your claims, but anecdotally I've been eating a very healthy mostly vegan low sugar diet, and haven't had a cavity in over 15 years despite using non-fluoride toothpaste. Same for my wife and two sons. There is definitely something to diet and dental health in my opinion.
