What Causes Clicking in the Jaw TMJ

Have you ever experienced a clicking or popping sound when you open your mouth or chew? If so, you may be one of the many people who suffer from temporomandibular joint disorder (TMJ).

This condition can be an uncomfortable and painful experience, often causing difficulty in speaking, eating and even sleeping. But what causes this clicking sensation in the jaw, and how can you prevent it?

In this blog post, we will delve into the fascinating world of TMJ and explore the various culprits behind jaw clicking, so you can better understand and manage your symptoms.

1. Clenching or grinding teeth

Clenching or grinding teeth, also known as bruxism, can be a common cause of clicking in the jaw and TMJ disorder. This action places excessive pressure on the jaw joint, leading to pain and discomfort. Bruxism can be caused by stress, anxiety, and sleep disorders. It may also happen due to misaligned teeth or an abnormal bite.

If left untreated, bruxism can cause significant damage to the teeth and jaw joint. It can even lead to tooth loss and difficulty in opening or closing the mouth. If you suspect that you have bruxism, it is essential to consult your dentist as soon as possible.

Treatment options for bruxism include jaw exercises, stress management, and medication to relax the jaw muscles. Your dentist may also recommend a mouthguard or splint to reduce the pressure on your teeth and jaw. These devices are specially designed to fit your mouth and provide cushioning between your upper and lower teeth.

2. Arthritis

Arthritis is a common cause of jaw clicking and pain. This condition is an inflammation of the joint and can affect any joint in the body, including the jaw. Arthritis of the jaw joint can be caused by various factors such as aging, trauma, infection, genetic predisposition, or autoimmune disease. The symptoms of arthritis in the jaw joint include pain, stiffness, swelling, and difficulty chewing or speaking.

One of the most common types of arthritis affecting the jaw joint is osteoarthritis, which is caused by wear and tear of the joint cartilage over time. This can lead to bone spurs, inflammation, and pain. Another type of arthritis affecting the jaw joint is rheumatoid arthritis, an autoimmune disorder where the body attacks the joint. This can cause damage to the joint and lead to pain and deformity.

3. Malocclusion of teeth

Malclusion of the teeth, also known as misalignment of the teeth and jaws, is a common cause of jaw popping and clicking. This condition can also lead to discomfort when biting and chewing, as well as speech difficulties and jaw pain. Malocclusion can be caused by genetic factors, but it can also result from bad habits like thumb-sucking or prolonged bottle feeding. As the teeth develop, they can grow in crooked or out of alignment, leading to misalignment of the jaw. Additionally, injuries to the jaw or face can cause malocclusion.

Orthodontic treatment is often necessary to correct malocclusion of the teeth. Braces and other corrective devices can help straighten the teeth and improve jaw alignment. In some cases, surgical intervention may be necessary to correct severe misalignment.

4. Myofascial pain syndrome

Myofascial pain syndrome is a chronic condition characterized by the presence of trigger points, also known as knots, in the muscles and fascia. These trigger points are sensitive to palpation and can cause pain in a localized area, as well as referred pain to other body parts. Myofascial pain syndrome’s causes vary and can include muscle overuse, trauma, poor posture, stress, and underlying medical conditions such as fibromyalgia and chronic fatigue syndrome. Treatment options for myofascial pain syndrome include physical therapy, massage therapy, trigger point injections, and medication. Additionally, lifestyle modifications such as stress reduction and good posture can also help to alleviate symptoms.

5. Obstructive sleep apnea

Obstructive sleep apnea is a common disorder that affects millions of people worldwide. It is characterized by shallow breathing or pauses in breathing while asleep. It can lead to a clicking sound in the jaw, which can be a symptom of temporomandibular disorder (TMD). Moreover, people with obstructive sleep apnea tend to grind their teeth while sleeping, which can further aggravate TMD symptoms.

The symptoms of obstructive sleep apnea may include loud snoring, interrupted breathing during sleep, morning headaches, and excessive daytime sleepiness. If left untreated, it can increase the risk of serious health problems such as high blood pressure, heart attack, and stroke. There are two types of sleep apnea – obstructive sleep apnea and central sleep apnea. Both can cause jaw popping.

6. Central sleep apnea

Central sleep apnea is a type of sleep disorder that affects the body’s ability to regulate breathing during sleep. Unlike obstructive sleep apnea, which is caused by a physical obstruction in the airway, central sleep apnea is a neurological condition that affects the brain’s ability to send signals to the muscles that control breathing. This can lead to episodes of paused or shallow breathing during sleep, which can cause a range of health problems, including daytime fatigue, high blood pressure, and heart disease.

One of the primary causes of central sleep apnea is damage to the part of the brain that controls breathing, which can occur as a result of conditions like stroke, Parkinson’s disease, or multiple sclerosis. Other factors that can increase the risk of central sleep apnea include the use of certain medications, alcohol or drug abuse, and obesity.

7. Infection of the salivary gland

Salivary gland infection is one of the many causes of jaw popping and TMJ. This condition occurs when the salivary glands become inflamed due to the presence of bacteria or viruses. In some cases, obstruction of the salivary gland can also cause an infection.

The infection can infect the parotid gland, located inside each cheek, submandibular glands below the jawbone, or sublingual glands under the tongue. The gland can become swollen, tender, and painful, which can make it difficult to talk or eat.

In addition to jaw popping, other symptoms of salivary gland infection include dry mouth, bad breath, fever, and difficulty opening the mouth fully. To prevent salivary gland infections, it’s essential to maintain good oral hygiene and stay hydrated. Additionally, avoiding foods that require excessive chewing or acidic beverages can reduce the risk of infection.

8. Wisdom teeth or molar tumour

Many people experience clicking or popping sensations in their jaw, which may be a sign of TMJ or temporomandibular joint disorder. One common cause of this condition is retaining wisdom teeth. When these teeth erupt, they can cause occlusal issues and crowd other teeth, leading to improper tooth contact during oral function. This can strain the temporomandibular joint, which connects the lower jaw to the skull, leading to impaired oral function, facial discomfort, and headaches.

If you’re experiencing TMJ disorder, removing your wisdom teeth may improve your occlusion and alleviate strain on your TMJ. In severe cases, corrective or reconstructive procedures may be necessary to reposition the jaws or repair damage to the TMJ itself.

It’s important to note that keeping your wisdom teeth can lead to other oral health issues, so seeking treatment for TMJ disorder and removing these teeth can be beneficial to your well-being. Additionally, if you have a molar tumor, which is a rare type of tumor that can develop in the wisdom teeth, it may need to be removed to prevent damage to surrounding teeth and tissue.

9. Injury or dislocation of the jaw

Injuries to the jaw can cause clicking in the TMJ, resulting in discomfort and pain. Physical trauma to the jaw can damage the cartilage and ligaments involved in the temporomandibular joint, leading to improper alignment and movement. Dislocations of the jaw can also occur due to impact or excessive force, causing the jaw to become displaced and resulting in popping or clicking sounds.

10. Joint disorder or dysfunction (TMJ)

Temporomandibular Joint (TMJ) disorder is a condition that affects the jaw joints and surrounding muscles and ligaments. It can be caused by trauma, an improper bite, arthritis, or wear and tear. The TMJs connect the lower jawbone to the skull and assist in movements like chewing and speaking. TMD refers to any dysfunction of the TMJ. Many people use the terms TMJ and TMD interchangeably. TMJ dysfunction occurs when the muscles and ligaments around the jaw joints become inflamed or irritated. The condition may be acute or chronic, and the resulting pain may be mild or severe.

TMJ disorder can be caused by injury to the jaw joints or surrounding tissues, or dislocation of the disk between the ball and socket joint. Those between 20 to 40 years of age are more prone to this disorder, particularly women than men. Symptoms include jaw tenderness, headaches, earaches, facial pain, neck or shoulder pain, difficulty opening the mouth wide, jaws that lock in the open/closed-mouth position, clicking, popping, or grating sounds in the jaw joint when opening or closing the mouth, and changes in the way teeth fit together.
