Jaw clenching and TMJ (temporomandibular joint) pain often occur when the muscles around the jaw are overactive, leading to tension, discomfort, and sometimes even headaches or worn-down teeth. Neuromodulators can help treat this condition by relaxing the overactive jaw muscles, reducing the force of clenching and alleviating pain. This approach not only relieves tension but can also slim the jawline over time, providing both functional and aesthetic benefits.
