Dentistry is absolutely one of the most dangerous and destructive medical professions, but it has never been held responsible for the massive trail of death and health destruction that it has caused. Dentists almost never understand or inform their patients that (any level of) tooth decay is caused in fact my a nutritional and mineral deficiency. Instead, the vast majority of dentists are more than happy to continue with the constant drill and fill that slowly destroys teeth and health. (I won't even bother at this point to go into the incredibly deadly silver amalgam fillings (a.k.a. mercury amalgams) and how they chronically destroy peoples' immune systems. You can look this up yourselves.)
Eventually, drill and fill moves to root canals which are dead teeth that act as breeding grounds for pernicious infections and chronic disease. Drill and fill also leads to extractions, implants, and other very dangerous replacement / corrective approaches and materials. The mouth then becomes a breeding ground for disease despite that all of this could have been prevented through correcting the mineral depletion along with Minimally Invasive Dentistry.
The whole story gets even uglier when you apply the Electrical Body model. The teeth act as fuses for electrical meridian channels that run the energy flows of the body through the conductive connective tissue of the body. The Chinese mapped these out over a thousand years ago. Once the teeth are compromised, all the organs on those electrical circuits are compromised as well. This leads to an undiagnosed cycle of chronic disease that dentists almost never understand that they are causing.
So next time people see a smiling dentist sign, they should realize that they better ask the right questions before they let any invasive work be done on their teeth. There are far better options and people need to research them before they let dentists anywhere near their teeth for anything more than a simple cleaning. (And by the way, people should never take any of these ridiculous sodium fluoride treatments either since this substance is a toxic waste product of aluminum processing and is historically a chief ingredient in insecticides and rat poisons.)
You are absolutely correct!
