filling up. One raw food guy, had his root canal fall out, and it somehow healed enough not to cause pain. (david wolfe if you want to check)
I have heard of fillings falling out. Of course if you go to the dentist, he will fill it. But dentists know as much about health as doctors, not very much. They are trained in disease not health.
At my worst health, my saliva PH was 4.5. My saliva was dissolving my teeth! I asked my dentist what I could do to save my teeth. He had no idea! Their books say saliva is 7.2, that's what makes you remineralize. So what does it mean if your saliva is 4.5. They have no idea haha
