There is a small, but very important structure that is vital to the proper functioning of our teeth. Teeth are not simply fused to our jaw bones. There is a system of fibers called the periodontal ligament that forms an attachment between the roots of the teeth and the bony supporting socket. During normal chewing, tremendous pressure is applied to the teeth and transferred along the root to the underlying bone. The periodontal ligament serves an as effective "shock absorber." It cushions both the horizontal and vertical forces applied to the teeth. If a person applies too much pressure to their teeth, the periodontal ligament may not be able to absorb all the force. This usually results in sensitivity to temperature and chewing pressure. The periodontalligament has some ability to adapt to excess pressure. When X-rays are taken of patients that habitually grind their teeth, we can actually see a widening of the ligament space. If the ligament becomes too wide we start to detect loosening of the teeth. The most important way to keep the periodontal ligament healthy is to avoid overloading it. People that chronically clench or grind their teeth should wear a guard that can provide additional protection.
