What is the term for a thin, fibrous ligament that connects a tooth to the bony socket?

The term for the thin, fibrous ligament that connects a tooth to its bony socket is the periodontal ligament. This ligament plays a crucial role in dental health as it helps to anchor the tooth securely within the alveolar bone, allowing for stability while also providing some flexibility during activities such as chewing. The periodontal ligament is composed of numerous collagen fibers, which help to absorb forces exerted on the tooth and facilitate the movement of the tooth during orthodontic treatment.

Understanding the function and importance of the periodontal ligament is essential, as it not only supports teeth but also acts as a sensory organ, allowing individuals to perceive sensations like pain or pressure in relation to their teeth.
