Proper functioning of the jaws and teeth is often hindered by malocclusion (a bad bite). Adjustments to the bite can be made so that your teeth fit together properly for chewing and swallowing. Minor polishing of the enamel surfaces or fillings of the teeth can help redistribute and redirect the biting forces.
An overbite or an underbite can sometimes be corrected with an occlusal guard, which realigns your teeth and bite.
