One of the most significant facts in connection with zone therapy is the intimate relation between morbid dental conditions and pain or even pathological changes in practically every section of the body. It has been demonstrated beyond a shadow of doubt, that points—or foci—of infection within the mouth, or in the teeth, frequently manifest disturbances most remote from their point of origin.

This is one reason why many physicians and surgeons, using the method, make a routine practice of sending every patient, in whom dental disease is even suspected, for a thorough overhauling by a competent dentist.

Another reason for striving to keep all our original teeth in their places is that nature intended to preserve the continuity—if it may be so termed—of our various nerve zones. Sound, healthy teeth and roots in their normal occlusion, seem to assist in the normal functioning of the entire zone chain of which they are important links.

Asthma, congestions, headaches, neuralgia, conditions affecting the nerves of the head or the ears, or even partial deafness, have been materially improved, and many times completely cured, by the application of a galvanic cautery around the necks of the teeth, by pressure on the teeth themselves in the zone affected, or even by having the patient “grind” the particular teeth related to those areas which it is attempted favorably to influence.

In several instances, chronic frontal headaches in children have been cured by correcting faulty occlusion of the front teeth by that branch of dentistry known as “Orthodontia.” When after several months’ treatment, the teeth were restored to their normal alignment, and continuity of the nerve zone was re-established, the headaches cleared up, and there has been no return of them.
