Have you been struggling with jaw pain, finding it hard to open or close your mouth, or experiencing uncomfortable cramping in your jaw? These symptoms might be signs of a condition called locked jaw, or trismus. A locked jaw can make everyday tasks like eating, speaking, and even brushing your teeth challenging. In this article, we explain what causes a locked jaw and share some practical tips to help you relieve the tension and get back to feeling your best.
According to the Memorial Sloan Kettering Cancer Center, the hallmark symptom of lockjaw is the inability to open your mouth more than 35 mm (1.4 inches), which is less than the width of three fingers.
Causes of Locked Jaw
Temporomandibular Joint Disorders (TMD)
The temporomandibular joint (TMJ) connects your jawbone to your skull and enables jaw movement. TMD can result from arthritis, jaw injury, or chronic clenching and grinding of teeth (bruxism). These conditions can lead to inflammation, muscle spasms, and pain in the jaw, making it difficult to open the mouth fully.
Trauma or Injury
Physical trauma to the jaw or head can damage the muscles, ligaments, or bones involved in jaw movement. This damage can result in swelling, pain, and difficulty opening the mouth. Accidents, falls, or sports injuries are common sources of such trauma.

Dental Problems
Dental issues, such as impacted wisdom teeth, severe cavities, or infections can contribute to trismus. According to a 2023 study, infections near the mouth or jaw muscles, such as a peritonsillar abscess, can impact jaw movement and potentially lead to lockjaw. Infections can cause swelling and inflammation, restricting the movement of the jaw. Dental surgeries or procedures that involve the jaw can also result in temporary trismus due to trauma or inflammation.
Infections
Infections like tetanus can cause severe muscle stiffness and spasms, including in the jaw. According to a 2016 study, when tetanus is a factor, lockjaw can result in severe complications, including choking, difficulty breathing, and potentially death. Other infections, such as those in the salivary glands or tonsils, can also lead to jaw tightness and restricted movement.
Muscle Disorders
Conditions like myofascial pain syndrome, which causes chronic pain in the muscles, can affect the jaw muscles and lead to trismus. Muscle spasms and tension in the jaw muscles can restrict movement and cause discomfort.
Medical Conditions
Certain medical conditions, such as rheumatoid arthritis or fibromyalgia, can affect the joints and muscles, including those in the jaw. These conditions can cause inflammation, pain, and limited movement, contributing to a locked jaw.

Tips to Relieve Jaw Tension
Jaw Exercises
Simple jaw stretches and strengthening exercises can help you get better jaw mobility and ease that muscle tension. For instance, slowly opening and closing the mouth or moving the jaw from side to side can help loosen tight muscles. Repeating these exercises several times a day can promote flexibility and reduce discomfort.
Warm Compresses
Using a warm compress on the affected area can work wonders in relaxing your muscles and boosting blood flow, which helps ease pain and stiffness. Simply apply a warm towel or heating pad to your jaw for 15-20 minutes a few times a day to feel better.
Massage Therapy
Giving your jaw muscles a gentle massage can help reduce tension and help you feel more at ease. Use your fingers to apply light pressure and massage in circular motions around the jaw and temples. By doing so, you can reduce muscle spasms and improve your mobility.
Relaxation Techniques
Did you know stress and anxiety can contribute to jaw tension? Practicing relaxation techniques, such as deep breathing, meditation, or yoga can help reduce overall muscle tension and promote a sense of calm. Reducing stress can have a positive impact on jaw health.
Avoid Chewing Hard Foods
Eating soft foods can make a difference when dealing with jaw pain. Stick to easy-to-eat options like yoghurt, mashed potatoes, and soups to avoid putting extra strain on your jaw. This simple change can help reduce pain and give your jaw the time it needs to heal.
Maintain Good Posture
Poor posture, especially while working at a desk or using a computer, can contribute to jaw tension. You should ensure that your workspace is ergonomically set up, and take regular breaks to stretch and adjust your posture.
Consult a Professional
If jaw tension persists or worsens, it’s important to seek professional help. A dentist, oral surgeon, or physical therapist can provide a thorough evaluation and recommend appropriate treatments, such as physical therapy, dental adjustments, or even surgery in severe cases.
