Pain Under Ear Behind Jaw Bone Left Side | Causes & Relief

Introduction

Experiencing pain under ear behind jaw bone left side can be uncomfortable, especially when chewing, talking, swallowing, or turning your head. The discomfort may feel like a dull ache, sharp pain, tenderness, or pressure near the angle of the jaw.

Several structures are located close together in this area, including the jaw joint, teeth, salivary glands, lymph nodes, ear, and neck muscles. A problem affecting any of these structures can cause pain that seems to come from the same spot.

For example, pain that increases when chewing may be associated with a jaw joint problem, while tooth sensitivity and gum swelling may indicate a dental issue. A tender lump under the jaw may occur when lymph nodes respond to an infection.

What Does Pain Under the Left Ear Near the Jaw Mean?

Pain below the left ear and behind the jawbone refers to discomfort around the area where the lower jaw meets the upper neck. The pain may stay in one place or spread toward the ear, cheek, teeth, throat, or neck.

The location alone does not identify the cause. A dental infection, for example, can cause pain that travels toward the ear, while a temporomandibular joint disorder can produce aching around both the jaw and ear.

Consider these details when describing the pain to a healthcare professional:

• Pain while chewing: May suggest jaw joint, muscle, tooth, or salivary gland problems.

• Pain when swallowing: May be related to a throat or nearby infection.

• A tender lump: Could be a swollen lymph node or another type of swelling.

• Tooth sensitivity: May indicate decay, gum inflammation, or a dental abscess.

• Ear fullness or hearing changes: May suggest an ear-related condition.

• Pain during meals: Can occur when a salivary gland duct is blocked.

These are clues, not definitive diagnoses. Several conditions can produce similar symptoms.

Common Causes of Pain Under Ear Behind Jaw Bone Left Side

1. Temporomandibular Joint (TMJ) Disorders

The temporomandibular joint, commonly called the TMJ, connects the jawbone to the skull near the front of each ear. It helps you open your mouth, speak, chew, and yawn.

When this joint or its surrounding muscles become irritated, pain may occur around the ear and jaw. Common symptoms include jaw tenderness, discomfort while chewing, headaches, clicking sounds, and difficulty opening the mouth fully. Teeth grinding, jaw clenching, injury, and arthritis may contribute.

What may help: Temporarily choose soft foods, avoid chewing gum, and avoid opening your mouth excessively wide. A healthcare professional can assess persistent pain and recommend appropriate treatment.

2. Dental Problems or Tooth Infection

Dental problems are another possible cause of pain beneath the ear and along the jawbone. Tooth decay, gum disease, an infected tooth, or an impacted wisdom tooth may cause pain that spreads beyond the affected tooth.

Signs of a possible dental infection include:

• Throbbing toothache

• Pain when biting or chewing

• Sensitivity to hot or cold food and drinks

• Swollen or red gums

• A bad taste in the mouth

• Swelling around the cheek or jaw

• Fever

A dental abscess is an infection that requires prompt dental treatment. It will not reliably resolve on its own, and the infection can spread to surrounding tissues.

NHS inform

What may help: Arrange a dental assessment if you suspect a tooth infection. Do not try to drain an abscess yourself or rely on painkillers as a substitute for treatment.

3. Swollen Lymph Nodes

Lymph nodes are small structures that help the immune system respond to infections. They are found in the neck and beneath the jaw. When you have a cold, sore throat, ear infection, or dental infection, nearby lymph nodes may become swollen and tender.

You may notice a small lump beneath the left ear or near the jawline. The area might hurt when touched, and you may also have a sore throat, cough, or fever.

Lymph nodes that enlarge because of a common infection often improve as the illness settles. However, a lump that grows, feels hard or fixed, or does not improve should be assessed by a healthcare professional.

NHS

4. Ear Infection or Another Ear Problem

An ear infection or other ear condition may cause pain that seems to extend into the jaw. The likelihood of an ear-related cause increases when discomfort occurs alongside ear fullness, discharge, hearing changes, or fever.

Ear pain can also be referred from nearby structures, including the teeth and jaw joint. Therefore, pain near the ear does not automatically mean the ear itself is infected.

NHS

+1

What may help: Seek medical advice if ear pain persists, worsens, or occurs with fever, swelling around the ear, fluid discharge, or changes in hearing. Avoid putting cotton buds or unprescribed substances inside the ear.

5. Salivary Gland Inflammation or Blockage

Salivary glands produce saliva to help moisten food and begin digestion. Some glands are located near the ear and beneath the jaw. A blocked salivary duct, sometimes caused by a small stone, can prevent saliva from flowing normally.

Possible symptoms include:

• Swelling near the ear or beneath the jaw

• Pain that becomes stronger during meals

• Dry mouth

• Tenderness in the affected area

• Redness or fever if infection develops

Pain that repeatedly intensifies when eating may be a useful clue to a salivary gland problem. Drinking water and gently massaging the area may help in some cases, but persistent swelling or signs of infection require medical assessment. Do not use sharp objects to try to remove a stone.

NHS

6. Muscle Strain or Jaw Clenching

The muscles around the jaw and neck can become sore after prolonged chewing, teeth grinding, clenching during stress, or sleeping in an uncomfortable position. This discomfort may be felt beneath the ear or along one side of the jaw.

Muscle-related pain may feel tender or tight and can become more noticeable when you chew or move your head. However, similar symptoms can occur with other conditions, so ongoing pain should not automatically be attributed to muscle strain.

Resting the jaw, avoiding hard foods, and reducing clenching may help mild discomfort.

7. Less Common Causes

Less commonly, pain in this area may be associated with jaw arthritis, nerve irritation, an injury, or another condition affecting the head and neck. Persistent unexplained pain, a growing lump, facial numbness, or unexplained weight loss warrants medical evaluation.

The aim is not to assume the worst, but to avoid overlooking symptoms that need investigation.

Symptoms That May Help Identify the Cause

Pay attention to how long the pain has lasted, whether it is getting worse, and whether swelling or other symptoms have developed. These details can help a doctor or dentist decide which examinations are needed.

How to Relieve Mild Jaw Pain at Home

Home care may help if the pain is mild and there are no warning signs. The right approach depends on the cause, and home remedies cannot treat every dental, ear, or salivary gland condition.

1. Eat Soft Foods Temporarily

Choose foods that require minimal chewing, such as soup, yogurt, mashed vegetables, and soft eggs. Avoid hard, chewy, or crunchy foods if they increase the pain.

2. Apply a Warm Compress

For mild muscle or jaw joint discomfort, try a comfortably warm compress against the painful area for short periods. Keep the temperature gentle to avoid burns. If warmth makes the pain worse, stop using it.

3. Avoid Clenching Your Jaw

Keep your jaw relaxed when you are not eating. Avoid chewing gum, biting hard objects, or repeatedly testing the painful movement. If you grind your teeth during sleep, ask a dentist whether a suitable mouthguard may help.

4. Drink Enough Water

Staying hydrated supports normal saliva production. This may be useful when a salivary gland problem is suspected, although water alone will not resolve every blockage or infection.

5. Use Pain Relief Carefully

If you need an over-the-counter pain reliever, follow the product label and ask a pharmacist or healthcare professional if you are unsure whether it is safe for you. Some medicines are unsuitable for certain medical conditions, pregnancy, or interactions with other medicines.

Important: Do not take leftover antibiotics or place aspirin directly on your gums. These approaches may cause harm and will not reliably treat the underlying cause.

If pain persists, worsens, or repeatedly returns, arrange a medical or dental assessment rather than continuing home treatment indefinitely.

When Should You See a Doctor or Dentist?

Some symptoms need prompt attention because infections and swelling around the mouth, jaw, and neck can become serious.

A suspected dental abscess needs urgent dental care. Difficulty breathing or swallowing, or swelling that threatens the airway, requires emergency assessment.

If the pain is mild but does not improve, or you are unsure whether it comes from your teeth, ear, or jaw joint, arrange an appointment rather than guessing the cause.

How Is the Cause Diagnosed?

A healthcare professional will usually begin by asking about the location, severity, duration, and pattern of your pain. They may ask whether it worsens during meals, chewing, swallowing, or jaw movement.

Depending on your symptoms, the assessment may include:

• Jaw examination: Checking movement, tenderness, clicking, and the ability to open your mouth.

• Dental examination: Looking for tooth decay, gum inflammation, infection, or wisdom tooth problems.

• Ear examination: Checking for inflammation, discharge, or other abnormalities.

• Neck examination: Assessing swollen lymph nodes, lumps, or tenderness.

• Additional tests: Imaging, blood tests, or other investigations when the examination suggests they are necessary.

Treatment depends on the underlying cause. TMJ-related pain may respond to conservative care, while a dental abscess requires dental treatment. Ear infections and salivary gland problems need care tailored to their specific cause.

Frequently Asked Questions

1. Why do I have pain under my left ear behind my jawbone?

Possible causes include TMJ disorders, dental infections, swollen lymph nodes, ear conditions, salivary gland problems, and muscle strain. The location alone cannot identify the exact cause. Other symptoms and a clinical examination help narrow down the possibilities.

2. Can TMJ cause pain under the ear?

Yes. The temporomandibular joint is located close to the ear, and TMJ disorders can cause pain around the ear and jaw. Chewing discomfort, jaw tenderness, clicking, and difficulty opening the mouth may also occur.

Mayo Clinic

3. Can a tooth infection cause pain near the left ear?

Yes. A dental abscess or other dental problem can cause pain that spreads toward the jaw, ear, and neck on the same side. Tooth sensitivity, gum swelling, a bad taste, or fever may provide additional clues. Suspected dental abscesses need prompt dental treatment.

4. What does a painful lump under the ear mean?

It may be a swollen lymph node responding to an infection, but other causes of lumps are possible. Seek medical advice if it grows, feels hard or fixed, does not improve, or occurs with persistent unexplained symptoms. Difficulty breathing or swallowing requires emergency care.

NHS

5. How can I relieve mild pain under the jaw at home?

Depending on the cause, temporary measures include eating soft foods, avoiding gum and hard chewing, relaxing the jaw, drinking water, and using a comfortably warm compress. These measures do not replace treatment for an infection or another underlying condition.

6. When should I worry about left-sided jaw pain?

Seek emergency care for breathing or swallowing difficulties, rapidly increasing swelling, or sudden facial weakness. Prompt assessment is also important for severe pain, fever with swelling, suspected dental infection, hearing changes, or a persistent unexplained lump.

Key Takeaways

• Pain under the left ear behind the jawbone can have several causes, including dental, jaw joint, ear, lymph node, and salivary gland problems.

• Pain during chewing may suggest a jaw or dental issue, while pain during meals with swelling may point toward a salivary gland problem.

• Mild discomfort may improve with soft foods and avoiding jaw strain, but home care cannot treat every underlying cause.

• A suspected dental abscess requires prompt dental treatment.

• Breathing or swallowing difficulties and rapidly increasing swelling are emergency warning signs.

• Persistent, worsening, or unexplained pain should be assessed by a qualified healthcare professional.

Conclusion

Pain under ear behind jaw bone left side can result from several conditions, ranging from temporary jaw muscle strain to dental infections or salivary gland problems. Paying attention to when the pain occurs, whether a lump or swelling is present, and whether you have fever, toothache, or ear symptoms can help guide the next step.
