Pain beneath the ear and behind the jawbone can range from a mild annoyance to a sharp, persistent ache that interferes with daily activities. You may notice discomfort while chewing, talking, yawning, or even turning your head. Although this type of pain is often caused by minor problems that improve with time, it can sometimes signal an infection, joint disorder, or another medical condition that requires treatment.
The area around the ear and jaw contains many important structures, including the temporomandibular joint (TMJ), salivary glands, facial muscles, nerves, lymph nodes, and parts of the ear. Because these structures are located so close together, pain from one area can easily spread to another, making it difficult to identify the exact source without a proper examination.pain under ear behind jaw bone left side
Understanding the possible causes can help you know when simple home care is enough and when it is time to seek professional medical advice.
Common Causes of Pain Behind the Jaw and Under the Ear
Several conditions can cause pain in this part of the face and neck. Below are the most common reasons.
1. Temporomandibular Joint (TMJ) Disorders
The temporomandibular joint acts as a hinge that connects your lower jaw to your skull. Every time you eat, speak, yawn, or smile, this joint is at work.
When the TMJ becomes irritated or inflamed, it can cause pain around the ear and jaw.
Common symptoms include:
- Pain while chewing
- Clicking or popping sounds when opening the mouth
- Jaw stiffness
- Difficulty opening the mouth fully
- Headaches
- Ear discomfort without an ear infection
TMJ disorders may develop because of teeth grinding, jaw injuries, arthritis, stress, or long-term jaw clenching.
2. Ear Infections

Typical symptoms include:
- Ear pain
- A feeling of pressure inside the ear
- Reduced hearing
- Fever
- Fluid draining from the ear
Children experience ear infections more often, but adults can develop them as well, especially after colds or sinus infections.
3. Swollen Lymph Nodes
Lymph nodes help protect your body by fighting bacteria and viruses. When you have an infection, these small glands can become enlarged and tender.
You may notice:
- A painful lump beneath the jaw
- Tenderness when touching the area
- Fever
- Fatigue
- Sore throat
In most cases, swollen lymph nodes return to normal once the infection has resolved.
4. Dental Problems
Many people are surprised to learn that tooth problems can cause pain near the ear.
Possible dental causes include:
- Tooth abscess
- Impacted wisdom teeth
- Severe cavities
- Gum infections
- Cracked or damaged teeth
Dental pain often spreads through nearby nerves, making it feel like the discomfort is coming from the jaw or ear instead of the tooth.
Other signs may include swollen gums, tooth sensitivity, difficulty chewing, or bad breath.
5. Salivary Gland Disorders
The salivary glands produce saliva, which keeps your mouth moist and helps digest food. If one of these glands becomes blocked or infected, pain may develop near the ear and jaw.
Symptoms may include:
- Swelling below the ear
- Pain during meals
- Dry mouth
- Unpleasant taste
- Fever
Salivary gland infections are more common in older adults and people who are dehydrated.
6. Muscle Strain and Neck Tension
Pain behind the jaw is not always caused by an infection or joint problem. Sometimes it results from strained muscles in the neck and jaw.
Muscle strain may occur because of:
- Poor posture
- Long hours using computers or mobile phones
- Sleeping in an uncomfortable position
- Heavy lifting
- Excessive chewing
The discomfort is usually a dull ache that becomes worse when moving the head or jaw.
7. Nerve Disorders
Certain nerve conditions can cause severe facial pain that extends to the jaw and ear.
One example is trigeminal neuralgia, a condition that affects the trigeminal nerve.
Symptoms may include:
- Sudden, intense facial pain
- Sharp, electric shock-like sensations
- Pain triggered by chewing, talking, brushing teeth, or touching the face
Although uncommon, nerve disorders should always be evaluated by a healthcare provider.
8. Mastoid Bone Infection
The mastoid bone is located directly behind the ear. A severe ear infection may spread into this bone, leading to a condition called mastoiditis.
Symptoms include:
- Severe pain behind the ear
- Swelling and redness
- Fever
- Ear discharge
- Hearing problems
This condition requires prompt medical treatment to prevent complications.
Less Common but Serious Causes
Most cases of jaw and ear pain are not serious, but some less common conditions should not be overlooked.
These include:
- Tumors affecting the salivary glands
- Jaw fractures
- Arthritis involving the jaw joint
- Autoimmune disorders
- Bone infections
- Certain cancers
- Referred pain from heart conditions, particularly in some people experiencing a heart attack
Persistent pain that continues to worsen should always be assessed by a healthcare professional.
Symptoms That May Accompany Jaw Pain
Depending on the underlying cause, additional symptoms may develop, including:
- Jaw stiffness
- Clicking or locking of the jaw
- Swelling near the ear
- Tooth pain
- Neck discomfort
- Fever
- Difficulty chewing
- Headache
- Ear fullness
- Facial tenderness
The pattern of symptoms often helps doctors determine the cause of the pain.
How Doctors Diagnose the Problem
To identify the source of pain, your healthcare provider will ask questions about your symptoms, including when the pain started, whether it comes and goes, and what activities make it worse.
During the physical examination, they may check:
- Jaw movement
- Ear health
- Teeth and gums
- Neck muscles
- Lymph nodes
- Salivary glands
Additional tests may be recommended if necessary.
Diagnostic Tests
Depending on your symptoms, your doctor may order:
- Dental X-rays
- Panoramic jaw imaging
- CT scan
- MRI
- Ultrasound of the salivary glands
- Blood tests
- Hearing evaluation
These tests help identify infections, joint disorders, nerve problems, or structural abnormalities.
Treatment Options
Treatment depends on the underlying condition causing the pain.
Home Care
For mild discomfort, your doctor may recommend:
- Resting the jaw
- Eating soft foods
- Applying warm compresses
- Using cold packs for swelling
- Drinking plenty of water
- Avoiding chewing gum
Many cases improve within several days with conservative treatment.
Medications
Depending on the diagnosis, treatment may include:
- Pain relievers
- Anti-inflammatory medications
- Antibiotics for bacterial infections
- Muscle relaxants
- Medications for nerve pain
Always take medicines exactly as prescribed.
Dental Treatment
If the pain originates from the teeth or gums, treatment may involve:
- Tooth fillings
- Root canal therapy
- Removal of impacted wisdom teeth
- Treatment of gum disease
- Professional dental cleaning
Prompt dental care can prevent the infection from spreading.
TMJ Therapy
People with TMJ disorders often benefit from:
- Jaw exercises
- Physical therapy
- Stress reduction
- Night guards for teeth grinding
- Bite adjustment when necessary
Surgery is considered only in severe cases that do not respond to other treatments.
Lifestyle Changes That May Help
Healthy daily habits can reduce the likelihood of recurring jaw pain.
Helpful tips include:
- Maintain good posture while working.
- Avoid clenching your jaw during stressful situations.
- Stretch your neck and jaw muscles regularly.
- Stay hydrated throughout the day.
- Schedule routine dental checkups.
- Limit chewing hard foods and ice.

Seek medical attention if you experience:
- Pain lasting longer than one week
- Severe swelling
- Fever
- Difficulty opening your mouth
- Trouble swallowing
- Hearing loss
- Ear discharge
- Facial numbness
- Increasing pain despite home treatment
Early diagnosis often leads to faster recovery and helps prevent complications.
Final Thoughts
Pain under the ear and behind the jawbone can have many different causes, from temporary muscle strain and dental problems to TMJ disorders, swollen lymph nodes, and ear infections. While many cases improve with rest and simple home care, ongoing or severe pain should never be ignored.
Paying attention to additional symptoms such as swelling, fever, hearing changes, or difficulty chewing can help your healthcare provider determine the underlying cause. With an accurate diagnosis and appropriate treatment, most people recover fully and return to their normal daily activities.
Maintaining good oral hygiene, managing stress, practicing good posture, and seeking medical advice when symptoms persist are the best ways to protect your jaw, ears, and overall health.
