Which behavior could potentially aggravate TMJ syndrome?

Excessive gum chewing can aggravate TMJ syndrome because it places continuous strain on the temporomandibular joint and surrounding muscles. This repetitive motion can lead to increased tension and irritation in the jaw, exacerbating any existing discomfort or dysfunction associated with TMJ. The act of chewing gum requires significant effort from the jaw muscles, which can lead to fatigue and pain, especially in individuals who already suffer from TMJ issues.

In contrast, frequent flossing, limiting jaw movements, and eating softer foods generally do not place undue stress on the TMJ. Flossing is a gentle oral hygiene activity that does not impact the joint. Limiting jaw movements can actually be a recommended strategy to manage TMJ symptoms, helping to reduce pain and inflammation. Eating softer foods can minimize the stress on the jaw, providing relief rather than contributing to the problem.
