What is one function of the buccinator in terms of denture stability?

The buccinator muscle plays a crucial role in denture stability and retention. Its main function is to keep the cheeks closely applied to the teeth and dental prostheses. By maintaining tension in the buccal area, the buccinator helps to prevent the dentures from dislodging during activities such as talking, eating, or swallowing. Additionally, this muscle facilitates the distribution of the masticatory forces on the denture base, which enhances overall stability in the oral cavity.

Thus, the contribution of the buccinator to retention and stability is essential for the effective function of dentures, making it a primary reason for its significance in this context. The other options, while related to oral function, do not directly address denture stability in the same manner.
