Why Is My Ear and Jaw Hurting? Common Causes Explained

Pain in the ear and jaw is a common and uncomfortable experience. These symptoms often appear together due to the close proximity of the structures involved, but can originate from various underlying causes. Understanding the potential sources of discomfort is the first step toward relief. Sometimes, pain in one area can “refer” or spread to another, making it challenging to pinpoint the exact origin without medical insight.

Understanding Jaw Joint Pain

A frequent cause of concurrent ear and jaw pain involves the temporomandibular joint (TMJ), leading to temporomandibular disorders (TMD). The TMJ connects your lower jawbone to the temporal bones of your skull, located just in front of each ear. This joint facilitates movements like chewing, speaking, and yawning.

When the TMJ or surrounding muscles become inflamed or dysfunctional, TMD can result. Symptoms include pain or tenderness in the jaw, aching pain around or in the ear, and clicking, popping, or grating sounds when opening or closing the mouth. Difficulty chewing, limited jaw movement, or a locking sensation of the jaw may also occur. Referred pain can extend to the face, head, and neck, including headaches.

Factors contributing to TMD include teeth grinding (bruxism) and jaw clenching, which often place strain on the TMJ and its muscles. Injuries to the jaw, head, or neck can also trigger TMD. Conditions like arthritis or displacement of the joint’s disc can lead to TMJ dysfunction.

Ear-Related Pain Sources

Pain originating in or around the ear can radiate to the jaw, creating combined discomfort. Ear infections are a common example. Both middle ear infections (otitis media) and outer ear infections (otitis externa) can cause referred pain. Inflammation and pressure from these infections can irritate nearby nerves, spreading pain to the jaw.

Otitis media can cause intense pain in or around the ear, sometimes extending to the jaw due to shared nerve pathways. Otitis externa, often caused by water exposure, results in inflammation and pain that can radiate to the jaw. Other ear issues can also contribute to jaw discomfort. Eustachian tube dysfunction, where the tube connecting the middle ear to the back of the throat doesn’t function properly, can cause ear discomfort felt in the jaw. Earwax impaction can create pressure in the ear canal, which may radiate to the temporomandibular joint and surrounding muscles, leading to jaw pain.

Dental and Oral Health Connections

Problems within the teeth, gums, and mouth are a common source of pain that can extend to the jaw and ear. This occurs because nerves supplying the teeth and jaw are interconnected with those supplying the ear and surrounding facial structures. Untreated dental cavities can cause pain that radiates beyond the affected tooth.

Tooth abscesses, pockets of pus from bacterial infection, can be painful and often radiate pain to the ear or jaw. Impacted wisdom teeth can cause pain, swelling, and infection in the gums and jawbone, with discomfort radiating to the ear. Their proximity to the TMJ means improper growth or infection can put pressure on the joint, leading to referred ear pain. Gum disease and cracked or fractured teeth can also cause pain that radiates through facial nerves to the ear and jaw. Cracked tooth syndrome, an incomplete crack in a tooth, can manifest as discomfort in the jaw or ear.

Other Contributing Factors

Beyond jaw joint, ear, and dental issues, other conditions can cause pain in the ear and jaw. Sinus infections (sinusitis) involve inflammation of the sinus cavities, located near the upper jaw, causing pressure and pain in the face. This discomfort can radiate to the upper teeth, jaw, and ears.

Nerve-related conditions can also cause pain in these areas. Trigeminal neuralgia is a disorder characterized by severe, sudden, electric shock-like pain along the trigeminal nerve, which branches to the forehead, cheek, and lower jaw. This pain can sometimes be felt in the ear. Salivary gland problems, such as inflammation or infection, can cause swelling and pain in the jaw area, often below the ear. Muscle tension in the face, neck, and shoulders, linked to stress, poor posture, or teeth clenching, can lead to referred pain in the jaw and ear. This myofascial pain occurs when trigger points in these muscles send pain signals to other areas of the head and face.

When to Consult a Professional

While some ear and jaw pain may resolve with home care, persistent, severe, or worsening symptoms warrant professional medical evaluation. Seek prompt medical attention if you experience signs of infection like fever or swelling, or if the pain follows an injury. Difficulty swallowing or breathing, inability to open or close the mouth fully, or sudden hearing changes are also warning signs.

A healthcare professional can diagnose the underlying cause of your ear and jaw pain, which is crucial for effective treatment. Self-diagnosis is not recommended, as many conditions share similar symptoms but require different approaches. Consulting a doctor or dentist ensures an appropriate treatment plan is developed, addressing the root of the problem and preventing complications.
