Jaw stiffness is a painful condition that can be caused by a variety of factors, including stress, anxiety, injury, infection, or underlying medical conditions. While the intensity and location of the pain can vary, jaw stiffness can significantly impact one's daily activities, such as eating and drinking, and may indicate a more severe underlying issue. This article will explore the various causes of jaw stiffness, the treatments available, and ways to relieve tension and pain.

What You'll Learn

Teeth grinding
There is no single cause of bruxism, but it is believed to be the result of a combination of physical, psychological, and genetic factors. For example, teeth grinding can be caused by stress or anxiety, and it is often seen in people who are high-strung, hyperactive, competitive, or aggressive. It can also be caused by certain medications, nicotine, alcohol, and caffeine.
In addition, teeth grinding can be a symptom of certain physical and mental health disorders, such as ADHD, Parkinson's disease, epilepsy, sleep apnea, and GERD. Sleep apnea, in particular, is thought to be a risk factor for bruxism as it can cause frequent arousals during sleep, which may lead to teeth grinding.
Bruxism can cause various problems, including pain, tooth fractures, headaches, and temporomandibular disorders (TMD). TMD can cause muscle problems in the jaw and joints, leading to restricted movement and a "clicking" noise. Treatment options for bruxism include medication, muscle relaxants, and mouthguards or nightguards to protect the teeth from damage.

Gum disease
Jaw stiffness and pain can be caused by a variety of factors, including gum disease. Gum disease, or periodontal disease, is an inflammation and infection of the tissues and bone that support the teeth. It is often caused by poor oral hygiene, but some people are more prone to this type of infection even with proper dental care.
Symptoms of gum disease include:
- Bleeding gums
- Bad breath
- Loose teeth
- Swollen, red, or purple gums
- Pain when chewing
- Gum recession
- A change in the way teeth fit together
Left untreated, gum disease can lead to the destruction of the underlying jawbone and tooth loss. Gum disease is the leading cause of tooth loss, and almost half of all adults in the United States have some form of it.
Diet can play a role in the development of gum disease. Diets low in fiber and micronutrients have been associated with a higher risk of oral diseases, including gum disease. Specifically, gum bleeding and destructive gum disease may be signs of a lack of micronutrients, such as vitamin C. Additionally, tooth loss has been linked to obesity, with research suggesting that obesity increases susceptibility to the bacteria that cause gum disease and cavities. Weight loss, on the other hand, may lead to decreased inflammation, a contributing factor to gum disease.
To prevent and treat gum disease, it is important to maintain good oral hygiene practices, such as regular brushing and flossing, and to schedule regular dental appointments. Ensuring a healthy diet with adequate nutrients can also help reduce the risk of gum disease.

Arthritis
RA is a chronic inflammatory condition that occurs when the body's immune system attacks its own cells. It often targets joints throughout the body, including the jaw. Symptoms of RA in the jaw include pain, stiffness, clicking, and limited movement. Treatment for RA includes anti-inflammatory medications and home remedies. Jaw pain can also be a symptom of RA in other parts of the body, such as the hands, fingers, and wrists.
Psoriatic arthritis (PsA) is an autoimmune condition that can affect any joint in the body, including the jaw. It causes joint pain, swelling, and stiffness. While rare, it can affect the TMJ, leading to jaw pain and stiffness. Home remedies and medical treatments can help manage PsA symptoms.
In addition to arthritis, other causes of jaw stiffness and pain include periodontal disease, sinusitis, tetanus (lockjaw), and trauma to the jaw, such as a broken or dislocated jaw. Grinding or clenching the teeth, also known as bruxism, can also contribute to jaw pain and stiffness. Stress and chronic pain can cause clenching, leading to a cycle of jaw pain and stiffness.
If you are experiencing jaw stiffness and pain, it is important to consult a healthcare professional for a proper diagnosis and treatment plan.

Stress and anxiety
Physiotherapist Michael Chan explains that stress and anxiety can cause jaw pain, and he has spent over a decade studying and honing his expertise in jaw physiotherapy. He notes that the greatest link his patients share is an elevated level of stress, and sometimes anxiety. Research supports Chan's observations, showing a strong link between stress, anxiety, and teeth grinding.
If jaw tension arises due to anxiety, healthcare professionals often recommend addressing the anxiety before treating the jaw tension. This can include psychotherapy and counseling, such as cognitive-behavioral therapy (CBT) or acceptance and commitment therapy (ACT). Meditation and other relaxation techniques, such as yoga and mindfulness, may also help relieve anxiety. Additionally, regular exercise, especially high-intensity workouts, can aid in managing anxiety symptoms.
To relieve jaw stiffness and pain caused by stress and anxiety, one can try jaw exercises, wear a mouthguard, and make behavioral changes. Specific facial stretches may help, such as performing slow, controlled mouth movements like opening and closing the jaw or moving it from side to side. One can also try resting the tongue's tip behind the upper front teeth and slowly opening the mouth as wide as possible, then slowly closing it. This stretch helps eliminate stress in the facial muscles, upper and lower jaw, and neck.

Sinusitis
While sinusitis-related jaw pain typically affects both sides of the face, it is important to note that temporomandibular joint disorder (TMJ or TMD) is another common cause of jaw pain that may be confused with sinusitis. TMJ disorder affects the temporomandibular joints located on both sides of the face, which connect the lower jaw to the skull and enable jaw movement. This disorder can cause joint inflammation and swelling, leading to pain and discomfort in the jaw and surrounding areas. Other potential causes of jaw pain include dental problems, gum disease, toothache, grinding teeth, and in rare cases, more serious issues such as a heart attack.
If you are experiencing jaw stiffness and suspect it may be related to sinusitis, there are several home remedies that can help alleviate the symptoms. Staying hydrated, using a humidifier, and nasal irrigation with a saline solution can help reduce sinus congestion and inflammation. Over-the-counter pain relievers, such as ibuprofen, can also help manage pain and inflammation. Applying heat or cold therapy to the jaw area can provide relief by relaxing muscles and reducing pain and stiffness.
If your symptoms persist or worsen, it is recommended to consult a healthcare professional or dentist for proper diagnosis and treatment. They may suggest treatments such as muscle relaxants, physical therapy, or in more severe cases, antibiotics or other medical procedures.
