As a dentist myself, I can concur the evidence shown in this documentary is either non existent, false or misinterpreted. The upside of this movie is that people should understand that treatments executed by dentists are always inferior to good oral healthcare and healthy teeth and that materials used by dentists are not as perfect as your own teeth and that inflammations of the gums and teeth can cause serious threats to the general health. There is evidence that poor oral health can result in Alzheimers disease, cardiac problem, diabetes, auto-immune inflammations, miscarriages and many more. So please, contain the number of moments eating or drinking anything other than water, brush your teeth, use dental floss, toothpicks or interdental brushes daily and visit the dentist regularly.
