Between eating, playing sports and chewing on anything from pencils to bubblegum, humans tend to put a lot of stress on our teeth. Luckily for us, each one is secured in place by the bones and tissues in our mouths.
Specifically, our teeth are anchored to the jaw by something called the alveolar bone. Never heard of it? You probably just know it by a different name. People commonly refer to this area as their tooth socket. But no matter what you call it, the alveolar bone is the primary support for your pearly whites.
Below the Surface
Your teeth are actually much longer than they appear on the surface, with a long root extending below the gums and into your jawbone. This deep anchor provides the strength needed to support the pressures of chewing. The part of the alveolar bone that encases these roots (the actual "socket") is called the alveolus. At the base of the root is a strong tissue called cementum that fastens each tooth to the alveolar bone foundation.
Both the upper jaw (maxilla) and lower jaw (mandible) contain alveolar bone. In addition, a special ligament completes the package, binding teeth securely into place for maximum support.
Alveolar Bone Loss
Unfortunately, certain dental problems and habits, as well as the effects of time, can cause the alveolar bone to resorb, or dissolve. This bone loss can also lead to adult tooth loss over time. Periodontal disease , also known as gum disease is the major cause of this condition, which makes gum disease treatment an important step in preventing alveolar bone loss.
