Anyone who voted this one, is definitely an endodontist or a dentist., And we know there are a lot of them out there. The people who gave it a 10 are all the patients who have been damage by root canal or leaving a dead tooth that is festering bacteria in the body. I have known hundreds if not, thousands of people who have had a but bad side effects from a root canal, and sometimes it goes on forever like in this story, and nobody even knows what's going on until they go to someone who understands the whole body, and how these dangerous toxic teeth stay in the mouth. It's actually not saving a tooth. It's leaving a dead tooth in the head. For any other organ in the body, we remove it when it becomes diseased. I know it's hard to lose a tooth, but this movie provides a real life example of what can happen, leaving down a path of auto immune diseases, and other sicknesses. At one time everybody was using mercury and teeth, and everyone said, it's perfectly safe, the dental industry said oh, mercury is the best thing, now no one uses mercury Because it's toxic. Why did we ever put mercury in teeth? I think one day and endodontist will be a thing of the past. A root canal will no longer be something that anyone will want any longer. Endodontist make at least $2000 per root canal tooth, and they don't give informed consent to the people who get them. I really could relate to what this movies message was saying. And it says a lot when they try to remove it from Netflix. Why silence someone? Where did free-speech go? I guess it goes to the special interest of the endodontist and the dentists. Don't silence the truth. Watch this movie, because it is a good representation of what thousands if not millions of people have endured.
