Masseter muscle spasms, also known as jaw muscle spasms or trismus, refer to involuntary contractions or tightening of the masseter muscle. The masseter muscle is one of the main muscles responsible for chewing and is located at the side of the jaw near the cheekbone.
These spasms can be painful and may cause difficulty in opening and closing the mouth. They are most commonly caused by excessive muscle strain or tension, often resulting from bruxism (teeth grinding or clenching) or temporomandibular joint (TMJ) disorder. In some cases, masseter muscle spasms may also be triggered by stress, anxiety, or certain medical conditions.
Symptoms of masseter muscle spasms may include jaw pain, stiffness, limited mouth movements, clicking or popping sounds in the jaw, headache, or earache. The severity and duration of the spasms can vary from person to person.
Treatment for masseter muscle spasms usually involves addressing the underlying cause. This may involve using relaxation techniques to reduce stress, practicing jaw exercises to relax the muscle, applying warm compresses to the affected area, or using over-the-counter pain relievers. In severe cases, a healthcare professional may recommend treatments such as physical therapy, botox injections, or the use of a dental splint or mouthguard to prevent teeth grinding.
It is important to consult with a healthcare provider for an accurate diagnosis and appropriate treatment if masseter muscle spasms persist or worsen.
