The primary function of the periodontal ligament is to support the tooth in its socket, also known as the alveolus. This ligament is a connective tissue structure that connects the cementum of the tooth root to the surrounding alveolar bone. Its main role is to absorb the forces applied to the tooth during activities such as chewing and biting, which helps to maintain the stability of the tooth within the jaw. The periodontal ligament not only provides physical support but also plays a role in sensing pressure and pain, contributing to the overall health and function of the tooth.

The other options pertain to different functions within oral health, but they do not encapsulate the primary role of the periodontal ligament. For example, while anchoring the gums to the teeth is important for oral integrity, it is primarily the gingival fibers that perform this function. Supplying nutrients to the enamel is not within the realm of periodontal ligament responsibilities, as enamel does not have a vascular supply. Finally, assisting in tooth development is primarily related to processes occurring in the dental pulp and surrounding tissues rather than the established support functions of the periodontal ligament.
