Causes of Jaw Pain On One Side

Jaw pain is a common type of complaint associated with the lower jaw or mandible. One-sided jaw pain usually subsides on its own.

Although, persistent pain on one side, when left untreated, can become severe.

It can be a direct result of physical injury, behavioral, or systemic disease. Other symptoms can develop suddenly or slowly.

The following are possible causes and symptoms that accompany jaw pain.

1) Temporomandibular Joint Disorders

The temporomandibular joint is located on each side of the head in front of the ears. This is a soft cartilage disk that acts as a cushion between the joints.

A temporomandibular disorder is a condition in which the cartilage becomes damaged or misaligned.

Temporomandibular joint (TMJ) disorder is associated with other conditions such as dental issues, jaw injury, infection, arthritis, teeth clenching, or teeth grinding.

The exact cause of TMJ disorder is challenging to determine.

Temporomandibular disorders symptoms include jaw soreness and swelling, earaches, headaches, clicking or popping sounds on the jaw joint.

A lockup in the bones around the jaw can also signify TMJ disorder making it difficult to open or close it again.

Thus, facial muscles may compensate for TMJ disorders.

Eventually, this condition results in referred pain around the neck, head and shoulders.

Temporomandibular joint disorder may worsen over time and erode the joints between the skull and jaw, making an early diagnosis of TMJ disorders critical.

2) Myofascial pain syndrome

Myofascial pain syndrome is caused by muscle injury from overuse through repetitive motions. Pressure on trigger points of the muscles causes scar tissues to form.

Eventually, the jaw is affected and cause facial pain on one or both sides.

3) Dental issues

Jaw soreness or sudden pain on one side can be caused by a dental problem such as an abscessed tooth, cavities, gum disease, emerging wisdom teeth, and misaligned teeth.

Misaligned teeth can interfere with jaw movement and cause pain because the jaw muscles try to compensate.

An abscessed tooth or tooth infection occurs when nerves, tissues, and blood vessels become infected. This infection collects pus in the center of the tooth.

An abscessed tooth can spread to the gums and bones, leading to pain around the mouth and jaw.

Facial swelling, tooth pain, bad breath, and fever are signs and symptoms that you have an abscessed tooth or cavities.

4) Sinusitis

Sinusitis comes from a cold or allergic reaction but eventually resolves on its own. Jaw pain is influenced by it when the sinus cavities behind the cheeks become inflamed.

Additional symptoms you may experience with jaw pain are trouble tasting or smelling, tiredness, nasal congestion, and phlegm.

5) Bruxism

Bruxism is one of the leading causes of jaw pain on one side.

It is also known as teeth grinding or clenching and usually occurs while sleeping and leads to damaged teeth.

Stress and anxiety can be a cause of teeth grinding. Stimulant drugs and caffeine can also influence this behavior.

6) Tumors and cysts

Tumors are masses of tissue, and cysts contain pus. These can have an impact on oral health by destroying bone and tissue in your mouth.

Tumors or cysts along the jaw and mouth can multiply, causing muscle or dental problems.

If you have red or white patches in your mouth, bleeding sores, painful gums, severe tooth pain, and a lump or growth you may need to be diagnosed for tumors or cysts.

Some may be cancerous, which makes it essential to seek immediate treatment from a healthcare provider.

7) Heart Attack

Jaw pain can also be a sign of a heart attack. Although rare, it is crucial to identify the signs for it.

Heart conditions such as angina or arteritis may trigger jaw pain accompanied by chest pains.

You may also experience muscle tension in the chest or arms, heartburn, indigestion, fatigue, dizziness. Immediate medical care should be sought for this condition.

8) Dislocation of the jaw

In rare cases, dislocation and injury to the jawbone cause jaw pain.

They are not apparent right away, but emergency care is needed for this type of injury.
