First, if pamelasmcelman checks back for an answer, you should google for "biological dentists," as they're more likely to be called. Also check the IAOMT website (should be easy to find with a search). But don't assume you'll automatically have a great dentist--ask lots of questions, ask for testimonials, and trust your gut. Try joining some Facebook groups. There's one that starts with "NICO" that's pretty good.
Those of us who have been on the Internet for at least a few months recognize the tone and vocabulary of these 1-star reviews, don't we? :) There are those who think if they yell loudly enough and insult the intelligence of others with playground epithets, we "stupid folks" will retreat whimpering into a dark closet and never be seen again. I really don't understand the motivation. Surely these reviewers are not all endodontists. I'm sure those folks have plenty of profitable work to keep them busy! Would someone go to the trouble of creating many accounts to post all these "reviews"? It sure sounds like it.
I haven't seen much substantiated criticism in all these reviews, but a lot of hot air. A few pokes at some dentists' histories...but anyone can say anything about anyone, can't they? Are all the dentists on the "other side" paragons? There was some tongue-in-cheek nonsense and wacky treatments mentioned in the documentary (from one man's experiences, which adds some color), but the really telling parts have been totally ignored by critics here. Many of the statistics in the movie came straight from mainstream dental or medical organizations. Experiments and studies were done properly and are easy to find documented.
The truth will eventually become mainstream, and people will look back in a few decades and laugh at the idea that anyone would believe a dead tooth could be safely left in the jaw, with no circulation or access by the immune system. Anyone can do their own research online or at the library and decide which sources and experts are credible. The shrillness of protest is just more evidence that a nerve has been touched. Pun intended. :)
And what on earth do the 1-star folks think the film is selling? I just watched it last night and I don't recall any products mentioned, website, or contact information. You're ridiculous!
To the filmmaker and Netflix, THANK YOU for making available information that has long been ignored and even suppressed. You are saving lives.
