What are causes of pain in one side of the jaw?

Pain on one side of the jaw is a common issue often caused by temporomandibular joint (TMJ) disorders, dental problems such as cavities, abscesses, or impacted wisdom teeth, and muscle tension from stress, teeth grinding, or clenching. Less common causes include sinus infections, nerve pain, or referred pain from the ear. Identifying the underlying cause is essential for choosing the right treatment and finding lasting relief.

Because one-sided jaw pain can stem from so many different conditions, self-diagnosing is difficult and delaying care can make things worse. The fastest way to narrow down what's driving your discomfort is to take a free, instant, online symptom check—it uses your specific symptoms to suggest possible causes and clear next steps, so you know whether to see a dentist, doctor, or specialist.

Explanation

Temporomandibular Joint Disorders (TMD):

One of the most common causes of pain in one side of the jaw is a condition known as temporomandibular joint disorder (TMD). This disorder affects the joint that connects the jawbone to the skull, leading to pain, discomfort, and difficulty moving the jaw. Symptoms may include clicking or popping sounds when opening or closing the mouth, as well as pain that can radiate to the ear or neck. TMD can result from various factors, including jaw injuries, arthritis, or teeth grinding (bruxism).

Dental Issues:

Dental problems can also lead to unilateral jaw pain. Conditions such as tooth decay, abscesses, or impacted wisdom teeth can cause localized pain that may be felt on one side of the jaw. Infections in the teeth or gums can lead to swelling and discomfort, making it difficult to chew or speak.

Muscle Tension and Strain:

Muscle tension or strain in the jaw can contribute to pain on one side. This can occur due to excessive clenching or grinding of the teeth, often related to stress or anxiety. Overuse of the jaw muscles, such as from chewing gum or eating hard foods, can also lead to discomfort.

Nerve Issues:

Nerve-related issues, such as trigeminal neuralgia, can cause sharp, shooting pain in the jaw. This condition affects the trigeminal nerve, which is responsible for sensation in the face and motor functions such as biting and chewing. Pain may be triggered by activities like talking, eating, or even touching the face.

Injuries and Trauma:

Injuries to the jaw, such as fractures or dislocations, can lead to pain on one side. Trauma from accidents or sports injuries can affect the jaw joint and surrounding muscles, resulting in significant discomfort.
