What is the function of the periodontal ligament?

• A. Protects the teeth from decay
• B. Absorbs shock during chewing
• C. Stimulates gum growth
• D. Secures the enamel

Answer: (B)

The function of the periodontal ligament is to absorb shock during chewing. This specialized connective tissue surrounds the roots of teeth and connects them to the alveolar bone, providing structural support. When chewing, the forces exerted on the teeth are significant, and the periodontal ligament acts as a cushion to absorb these forces, thus preventing damage to the tooth and surrounding structures. This shock-absorbing capacity is crucial for maintaining dental health and ensuring comfort during various functional activities like biting and chewing. In addition, the periodontal ligament plays a role in the overall maintenance and health of the tooth and surrounding tissues, but its primary and most recognized function pertains to shock absorption. Other options mention functions that do not directly relate to the primary and most important role of the periodontal ligament in dental health.
