Dentistry, like other Rockefeller owned and controlled medical establishment divisions, is deeply rooted in willful ignorance, lies and deception. As with other healthcare divisions, there are a number of circumstances in dentistry whereby profits are chosen over the genuine welfare concern of patients.  

In retrospect of the above, while this article outlines a number of things your dentist won't tell you, it also serves to provide insights into dentistry, so that you can get savvy, look after your teeth the natural way, learn to take control of your oral health.

Not a definitive account, but here are the things you need to know.

*From a dental x-ray of your teeth the dentist may tell you that a filling is needed as a cavity has been detected, but it may not be the case. Some dentists lie to you.  

A cavity is detected by an X-ray showing a dark area located at the tooth in question. Don't take the dentist's word for it, challenge him. Ask him to point to the darkened area on the x-ray where the cavity is said to be. If the dentist can't point to this dark area because there isn't one, and he still can't justify his decision to fill and drill, then no such cavity exists.
