This documentary saved my life. After suffering from joint pain, fatigue, and life-threatening complications from an infected salivary gland post dental cleaning, I decided to watch this when the series was on Netflix. Sure enough, I had to bulldoze my way through the dental and oral surgery community to have a cone beam CT (x-rays we're normal), where a small infection was seen at the tip of my root canal. I had it extracted and have felt so much better for years.
I agree with others, shame on Netflix for listening to the ADA. I wish that many people could have to opportunity to watch this great documentary as I am sure it will help others.
