Health Capsule Do you notice yourself clenching your jaw or grinding your teeth often? Do you sometimes wake up with jaw discomfort, earaches, or a headache? If so, you might be experiencing a condition known as bruxism, which refers to the habitual grinding or clenching of teeth. Occasional or mild teeth grinding might not be a cause for concern, but when it becomes frequent or intense, it can lead to a number of problems. These include jaw discomfort, tired muscles, and persistent headaches.
