Tooth Erosion

The tooth erosion phenomenon has been very thoroughly investigated by Dr. Gene McCoy (Dental Compression Syndrome).  I believe his conclusion that the erosion can be prevented by adjusting the shape of the teeth (equilibration) is only partially correct.  He fails to understand that in most of these cases the jaw is postured in a stressful position by the bite (i.e. the resting position for the muscles suspending the lower jaw is very different than where the teeth make the jaw go when the patient bites).  This makes the patient bite down slightly off causing excess trauma to the teeth and subsequent erosion.  Computer modeling shows that when the interface of two teeth is off, erosion occurs at the gum line and in the top of teeth (lines of Ludder, class VI lesions).
