Exercise for lock jaw:

Trismus is also called lockjaw. This can be caused by trauma or injury to the mastication (chewing) muscles. You need your chewing muscles for chewing your food and opening your mouth. Without it, it would be hard to eat, talk, brush your teeth, or swallow the food.

Lockjaw usually resolves itself in less than 2 weeks, but it can be very painful in the meantime. A permanent lockjaw can occur too. Whether trismus is around for days or months, daily performing exercises and massaging can ease the temporomandibular joint pain.

If you are suffering from trismus, you know it can affect your eating, talking, and oral hygiene very difficult. It is important to exercise your jaw to help it get stronger. Static stretching (holding a stretch) is a good way to test the limits of your jaw mobility; however, passive movement (moving parts of your body) used several times per day has proven to be very effective in decreasing inflammation and pain.

However, if exercising and stretching do not help, talk to your doctor or another healthcare provider. Medications such as non-steroidal anti-inflammatory drugs (NSAIDs), muscle relaxants, and steroids are usually the next step.

You may not think about your temporomandibular joints (TMJ) much, but you use them a lot of times. These joints connect your jawbone to your skull. Your TMJ is used in action every time you talking, chewing, and swallowing.

TMJ disorders occur when something went wrong with your jaw joints and jaw muscles. mostly, this happens because of a jaw injury, inflammation such as with arthritis, or overuse.

Trismus occurs due to:

Injury to the jaw
Oral surgery
Mouth infection
cancer
Radiation therapy for cancers of the head and throat.

TMJ disorders may be caused due to mild debilitating symptoms, such as:

Pain during chewing
Pain in your ear, face, jaw, and neck clicking, grating, or popping sounds in the jaw when you open or close your mouth locking of the jaw joint headaches

About Your Jaw

Our jaw is made up of a pair of bones. These bones form the framework of your mouth and teeth.

The maxilla is your upper jawbone.
The mandible is your lower jawbone.
The temporomandibular joint (TMJ) is where your mandible connects to your skull.
Your masseter muscle is the muscle that connects your mandible to your skull.

About your jaw muscles

Jaw-closing muscles:

Masseter, temporalis, and medial pterygoid

Jaw-opening muscles

Lateral pterygoid and digastric

TMJ pain may also be managed with simple lifestyle changes. You may wish to:

You have to eat a soft diet to allow the TMJ to relax
You have to avoid chewing gum
You have to avoid biting your nails
You have to avoid biting your lower lip
Try to maintain good posture
Limit large jaw movements, such as yawning and singing
You can use pain relievers such as ibuprofen and acetaminophen may help relieve TMJ pain.

Muscle relaxers may be used to relieve severe pain. Doctors may also recommend:

mouth guards to prevent teeth grinding and jaw clenching mouth guards to help realign your jaw use warm towels over the mouth ice, no more than fifteen minutes per hour, and not directly on the skin stress-relief techniques to help prevent behaviors that cause jaw tension acupuncture to relieve pressure in the affected area

Severe pain a occurs due to damaged joints may require more invasive treatments, such as corticosteroid injections into the TMJ. Surgery may be considered as a last option. There is not any scientific evidence that surgical interventions for TMJ disorders are safe and effective.

These exercises aim to create movement in your jaw muscles to prevent inflammation and pain. The stretching exercises can be repeated multiple times a day, and consist of opening and closing your mouth.

Before you start these exercises, you have to massage your cheek muscles using your pointer and middle finger on your cheekbone. Run your fingers down to your masseter muscle (muscle on the side of your face), which connects your jaw bone to your skull. Move your fingers in a clockwise motion for 20 seconds, 2 to 3 times a day. This movement helps you to loosen your jaw.
