That stands as a self-evident truth because that's how Murphy's Law works. It's a three-part process. First the zombies rise. Then they eat the dentists. Then you get a screaming toothache, and have to shoot it out of your head, Life R Cruel. On the other hand... Study of 'No Drill' Dentistry Shows Fillings Aren't Needed in Many Cases Look carefully at line 29. Catch that reference to cavities healing up all by themselves? Most dentists don't want you to know that. It turns out that there is an enzyme in human saliva that repairs tooth enamel. Care to guess what prevents it from working? Tooth paste. It coats the enamel with a long-lasting film that decay-causing bacteria can thrive under, and which blocks the enzyme completely. Healing stops. Decay continues. The most effective strategy to prevent tooth decay is 1) eliminate all refined sugars from your diet, and 2) brush you teeth with plain unscented non-antimicrobial soap. Then rinse your mouth twice. Your saliva can then start fixing up your teeth. You'll be able to tell because your teeth will (literally) be squeaky clean. If you use toothpaste. it will take seven rinsings to get the residue off your teeth. Which mostly doesn't happen. Plain soap does not taste bad. It has a neutral taste. Add a lot of cheap perfume and biocides, and it tastes terrible. Try soap for a month. You'll probably never go back to toothpaste. Plain soap, by the way, does not contain any added toxic waste. That is, it has no added fluoride compounds--specifically. All fluoride compounds are neurotoxic and the stuff in toothpaste can kill small children. Check the recommendations of the American Dental Association concerning fluoride toothpaste and small children, if you doubt me on that. The original toxic waste added to water was the "black liqueur" from paper factories. It was loaded with fluoride. The stuff was so hellishly toxic that disposing of it legally was costing the paper industry millions. So they bought a few politicians, and convinced us to drink it instead. Sweet, But I digress... Try soap for a month. You'll never go back to deathpaste. Err...I mean toothpaste.
