Locked jaw, also known as temporomandibular joint (TMJ) dysfunction, is a condition that can cause pain, discomfort, and restricted movement in the jaw. When you experience a locked jaw, it becomes difficult to open or close your mouth properly, and the jaw might feel stiff or stuck. This can be both painful and frustrating, making it challenging to speak, eat, or perform basic daily activities. Understanding the causes of a locked jaw and knowing how to find relief can help manage this condition effectively.
What Causes a Locked Jaw?
There are several potential causes for a locked jaw, with the most common being issues related to the temporomandibular joint (TMJ), which connects the lower jaw (mandible) to the skull. The joint allows for the smooth movement of the jaw, enabling activities like chewing, speaking, and swallowing. When this joint becomes injured, inflamed, or misaligned, it can lead to pain and stiffness, resulting in a locked jaw.
1. Teeth Grinding (Bruxism)
One of the most common causes of a locked jaw is bruxism, which is the involuntary grinding or clenching of teeth. Bruxism often occurs during sleep, especially in individuals who experience high levels of stress or anxiety. Over time, grinding and clenching can place excessive pressure on the TMJ, causing it to become irritated or misaligned. This can result in a locked jaw, along with accompanying symptoms like headaches, earaches, and jaw pain.
If bruxism is the cause of your locked jaw, a dentist may recommend wearing a nightguard, a custom-made device that helps prevent teeth grinding during sleep. Addressing stress and anxiety through relaxation techniques or therapy may also help reduce the occurrence of bruxism.
2. Jaw Injury or Trauma
In some cases, a locked jaw can be caused by an injury or trauma to the jaw. This can occur due to an accident, sports injury, or even an impact from chewing hard foods. Trauma to the jaw can cause damage to the TMJ, leading to inflammation, swelling, and difficulty moving the jaw. If you’ve experienced any type of injury to your jaw, it’s essential to seek medical attention to rule out fractures or dislocations.
3. Arthritis
Arthritis is another condition that can contribute to locked jaw. Both osteoarthritis and rheumatoid arthritis can affect the TMJ, causing inflammation, stiffness, and pain. Over time, this can lead to the degradation of the cartilage in the joint, making it difficult for the jaw to move smoothly. Individuals with arthritis may experience chronic jaw pain and limited jaw mobility, which can contribute to a locked jaw.
Managing arthritis with medications, physical therapy, and lifestyle changes can help alleviate symptoms and prevent further joint damage.
4. TMJ Disorders
Temporomandibular joint disorders (TMD) are conditions that directly affect the TMJ, leading to a variety of symptoms, including locked jaw. TMD can be caused by a combination of factors, such as jaw misalignment, stress, poor posture, or genetics. When the TMJ is not functioning correctly, it can result in pain, clicking sounds, and limited jaw movement.
If you suspect that you have a TMJ disorder, it’s essential to consult with a healthcare provider. A dentist or doctor can assess the joint and recommend appropriate treatments to improve jaw function and alleviate pain.

5. Infection
Infections in the jaw or surrounding tissues can also cause a locked jaw. Infections, such as an abscessed tooth or severe gum infection, can cause swelling and inflammation in the jaw area, leading to restricted jaw movement. If left untreated, infections can spread and result in more severe complications, including systemic illness.
If an infection is suspected, it’s important to seek medical care immediately. Treatment may involve antibiotics or, in more severe cases, surgical intervention to drain the infection.
How to Find Relief from a Locked Jaw
If you are experiencing a locked jaw, there are several methods you can try to alleviate the discomfort and restore normal jaw function.
1. Apply Warm or Cold Compresses
Applying a warm compress to the affected area can help relax the muscles around the TMJ and reduce pain. Alternatively, a cold compress may help reduce inflammation and numb the area if there is swelling. Applying a compress for 15-20 minutes at a time, several times a day, can provide significant relief.
2. Gentle Jaw Exercises
Gentle jaw exercises can help improve mobility and relieve tension in the jaw muscles. It’s important to perform these exercises carefully and avoid forcing the jaw to move if it’s in significant pain. Your dentist or physical therapist can recommend specific exercises to help strengthen and relax the muscles surrounding the TMJ.
3. Medications for Pain and Inflammation
Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help reduce pain and inflammation associated with a locked jaw. In more severe cases, your doctor may prescribe muscle relaxants or anti-inflammatory medications to relieve discomfort and improve jaw mobility.
4. Consider a Mouth Guard or Splint
If teeth grinding or bruxism is contributing to your locked jaw, wearing a mouth guard or splint at night can help protect the teeth and reduce pressure on the TMJ. A custom-made nightguard designed by your dentist can prevent clenching and grinding, providing relief from jaw pain and preventing further damage to the TMJ.
5. Seek Professional Treatment
In some cases, professional treatment may be required to address the underlying cause of a locked jaw. If your condition is related to a TMJ disorder or arthritis, your dentist may recommend specialized treatments such as physical therapy, corticosteroid injections, or even surgery in rare cases.
Conclusion
A locked jaw can be a painful and frustrating condition, but with the right treatment, relief is possible. Identifying the underlying cause of the locked jaw is essential for selecting the appropriate treatment. Whether it’s related to bruxism, injury, arthritis, or a TMJ disorder, various options are available to help manage the pain and restore normal jaw function. If you’re experiencing persistent symptoms, don’t hesitate to consult with a healthcare provider for further evaluation and treatment.
