There are many potential causes of a tight jaw. Your lifestyle, jaw disorders, and certain illnesses can all play a role in mild and severe jaw tightness.
Each side of your jaw has a joint (temporomandibular joint, or TMJ) and muscles that perform several tasks. Tight jaw joints muscles can affect chewing, yawning, speaking, and singing.1, 2
You may have jaw tightness that comes on suddenly. Alternatively, you may notice tension or low mobility in your jaw that persists over time. This can affect one or both sides of your jaw.
A tight jaw can have various causes, some of which might co-occur. Five significant causes of jaw tightness include:
Your jaw can tighten as a result of stress or anxiety. People’s bodies show stress in different ways, including tensing muscles. This includes the jaw muscles.
Stress and anxiety can also contribute to bruxism and TMJ disorders, which can tighten your jaw.
Many people engage in bruxism, an unconscious habit of clenching or grinding teeth. This can occur while you’re awake or asleep, and over time it can cause your jaw to stiffen or reduce mobility.
Bruxism can be a response to stress or anxiety, but it can have other causes, such as stimulant drugs and other underlying conditions.
Similarly, excessive chewing can overexert jaw muscles. Chewing gum, tough foods, and jaw exercise products can all cause a tight jaw. Take a break if you’ve recently chewed heavily and see if the stiffness subsides.
Temporomandibular joint disorder (TMD) includes various conditions that affect the jaw joint. TMD symptoms include:
The causes of TMD aren’t entirely clear. Stress, personality type, and conditions such as arthritis can all be risk factors.
Arthritis (joint inflammation) can cause your jaw to stiffen and lose mobility. There are many forms of arthritis, but the two most common are:
Tetanus is a potentially fatal infection, also referred to as lockjaw. It can cause involuntary spasms in the neck, jaw, abdominal, and other muscles. These painful contractions can cause breathing difficulties.
Tetanus can be treated, but it’s best to prevent it through vaccination. Most people in the United States are vaccinated against tetanus.
If you spend ample time sitting down looking at a screen, you may have rounded shoulders and a forward-arched neck. This poor posture can ultimately transfer tension to your jaw.
Maintaining good posture and mobility in your neck, back, and shoulders may help relieve jaw tightness.
Other potential causes of jaw pain or stiffness include:
Some of these causes are relatively minor, but others can be life-threatening.
See a doctor if you notice severe symptoms, such as fever or visible changes in your jaw.
If your jaw feels stiff or has a limited range of motion, you may also notice other symptoms, such as:
The specific symptoms you experience may differ depending on the underlying cause. Tetanus, for example, can cause your neck and abdominal muscles to tense.
Less commonly, jaw stiffness may follow up with fever, visible jaw appearance differences, or severe pain. Again, if you notice these symptoms, see a doctor.
See your dentist if you have jaw stiffness that:
Don’t ignore the issue if it worsens or involves other severe symptoms. Your dentist can identify the cause of your tight jaw and provide the necessary treatment.
If you are in severe pain or have symptoms of tetanus, see a doctor as soon as possible.
