Can be lost or left behind by accident

Your natural teeth are held securely in place by their roots in the jawbone. Disease, decay, or trauma may lead to the loss of all of one’s teeth. The roots had previously stimulated the surrounding bone, maintaining the jaw’s natural shape. However, with no roots in place, the jawbone will begin to resorb or shrink, because it no longer serves the purpose that nature intended.

The effects of missing teeth extend far beyond just having a toothless jaw. When teeth are missing from the jaw, the jaw bone shrinks, as it is no longer stimulated by the roots. When all teeth are missing from the jawbone, the entire jaw shrinks and thins.
