Inadvertent cheek biting during mastication, the process of chewing, constitutes a common oral annoyance. This unintentional act involves the teeth, typically the molars, pinching the soft tissue of the inner cheek while consuming food. Such incidents can range in severity from minor irritations to painful ulcerations.
The frequency of these occurrences can stem from a variety of factors. Misalignment of teeth, known as malocclusion, can increase the likelihood of cheek biting as the teeth do not properly align during chewing. Certain dental conditions, such as temporomandibular joint (TMJ) disorders, may also contribute to the problem by altering jaw movement. Furthermore, habits developed over time, potentially subconscious adjustments to chewing patterns, could predispose individuals to unintentionally bite their cheeks. Stress or anxiety can contribute to these habits as well.
