The Role of The Bite in TMJ Disorders

SUMMARY

In almost everybody, there is a single lower jawbone location at which all or almost all of the back teeth fit together fully.   You can find this lower jawbone location by tapping your back teeth together a few times until your bite feels solid on the back teeth of both sides. The way the teeth fit together here acts like a home base for the chewing system.  All jaw movements begin and end there, and the back ends of the lower jawbone (the condyles) are fully seated in the depths of their sockets there, cushioned by the disks.  The ease with which the teeth come together at this location and the comfort of the jaw muscles and the fit of the jaw joints (TMJs) at this location influence the resting tensions in your jaw muscles, which in turn influences your facial growth pattern as well as the health of your postural muscles.  If the bite is unstable, it can be stabilized by shaving down high spots or building up low spots.  If the bite is displaced, there are various ways to shift it to a better position depending on your dental condition.
