What is a common sign of clenching that might be observed in a patient?

A scalloped tongue is indicative of clenching, often resulting from the pressure exerted by the teeth during such activities. When patients clench their teeth, the tongue can be pressed against the teeth, leading to impressions or indentations around the edges, which creates a scalloped appearance. This sign is particularly familiar in the context of bruxism, where prolonged clenching or grinding may occur, indicating a potential issue with occlusion or stress.

While swollen gums and loosened teeth can be signs of other dental conditions like periodontal disease or advanced tooth mobility, they do not specifically indicate clenching behavior. Similarly, a dry mouth can result from various factors, including medications or dehydration, but it is not a typical sign associated with clenching. By recognizing a scalloped tongue in a patient, a dental professional can gain insights into potential bruxism or clenching, prompting further evaluation and appropriate interventions.
