What is a common trigger for acute TMJ flare-ups?

Acute TMJ flare-ups are often triggered by stress and the overuse of jaw muscles. When individuals experience stress, it can lead to increased tension in the jaw area, which may cause clenching or grinding of teeth (known as bruxism). This excessive pressure can exacerbate any underlying issues within the temporomandibular joint, leading to pain and restricted movement. Additionally, overuse of jaw muscles, whether through excessive chewing, grinding, or talking, can contribute to inflammation and irritation around the joint, resulting in flare-ups.

The other options do not generally serve as common triggers for acute TMJ issues. Using a mouthguard, for instance, is often a preventive strategy employed to reduce the impact of grinding and clenching, thus helping to avoid flare-ups. Consuming soft foods typically reduces the strain on the jaw and is often recommended for individuals with TMJ dysfunction to help alleviate symptoms. Maintaining proper posture may also be beneficial for jaw alignment and overall muscle tension but is not typically recognized as a direct trigger for acute TMJ flare-ups.
