>>19049868That's not what they do in a root canal. At least, not in 1st world countries. Pic related is what a root canal actually looks like. The dentist removes the pulp of the tooth disinfects and fills the cavity with pins and resin. Nothing can get inside, not bacteria or food/drink. But that's irrelevant because the bacteria that cause cavities don't "eat" tooth enamel. The eat the sugars left over from food, and metabolize them into acids. It's the acids that damage your teeth. If any bacteria got into the treated tooth somehow, it would starve. Of course, what you're describing can happen if the dentist screws up.
>skeleton all used to die with all their tooth on their skulls.That's because people lived to be 50-60 and didn't eat/drink corn syrup. Ancient humans didn't get diabetes or heart disease either; it's lifestyle related. Dentistry exists as a response to the modern lifestyle. Yeah it sucks that your dentist was greedy and screwed you over but that doesn't invalidate the entire practice. This is libtard-tier argumentation. "I feel as if I was discriminated against so society is racist".
>there is a dental paste that japanese people created that replenishes enamelI researched this for a bit; either you don't know what you're talking about or it doesn't exist. Toothpaste can strengthen weakened enamel by replacing the minerals, but the body will never re-grow lost enamel.
>>19049874Free calcium in the blood has nothing to do with teeth. Cells use calcium for all sorts of biological processes, but none of this matters anyways because enamel has no blood supply, and there's no biological process in humans by which the enamel in teeth is repaired. There's no process in nature by which this happens. Sharks, for instance, just drop their teeth and grow new ones. Are the jews making shark's teeth fall out? Were they doing this 400 million years ago when sharks first appeared?
