The periodontal ligament (PDL) is a lining around the root of the tooth. It absorbs the shock of chewing, and holds the tooth firmly in place. Cells in the periodontal ligament can degenerate and regenerate.
Periodontal Ligament Seen in Blue
The condition of a worn out tooth ligament is called chronic peridontitis and is a primary cause of tooth loss.
The periodontal ligament is a web of taut fibers running in all different directions that connects the cementum to the tooth bone. The image above shows some of those microscopic fibers.
How to Strengthen the Periodontal Ligament
A healthy diet tightens the teeth within the sockets. Good quality bone broth soups will strengthen the ligament, as well as good quality grassfed butter. A healthy diet for teeth and gums is discussed in more detail in the book Cure Tooth Decay.
You can also help the periodontal ligament with a special gum cleaning technique.
