You can experience jaw pain and tenderness due to joint damage, infection, or a toothache, among other causes. The other symptoms you have may help pinpoint the cause.

Sudden jaw pain is typically not serious. But if it occurs with other concerning symptoms, such as chest pain or a high fever, it may be an early indicator of a more serious health condition, such as a heart attack.

Here, we’ll go over some of the main causes, other symptoms to look for, and might be time to see a doctor or dentist.

You might worry about dental issues such as a cavity or abscessed tooth or wonder if you’ve been grinding your teeth at night.

Here’s a look at some common causes of jaw pain.

1. TMJ disorders

Temporomandibular joint (TMJ) disorders affect the joint that connects your skull and jaw. A disc separates the bones in this joint and helps it move properly. If the disc becomes misaligned or the joint is damaged, you may experience pain on one or both sides of your jaw.

Other symptoms of TMJ disorders can include:

Multiple factors can contribute to TMJ disorders, so it’s not always easy to find a specific cause.

Issues known to play a part in TMJ disorders can include:

If you have symptoms of a TMJ disorder, a healthcare professional or dentist can help figure out the underlying cause.

2. Sinusitis

Inflammation in your nasal cavities can cause sinusitis. This tends to happen if you’ve had a cold, but allergies and other medical conditions can also contribute to sinusitis.

If the sinus cavities behind your cheeks, known as the maxillary sinuses, are inflamed, you might feel pain in one or both sides of your jaw.

Other symptoms of sinusitis can include:

  • nasal congestion that makes it hard to breathe through your nose
  • yellow or green mucus that drains from your nose or into your throat (post nasal drip)
  • facial pain, pressure, and swelling
  • pressure and pain in your ears and head
  • fatigue
  • difficulty smelling or tasting

Sinusitis often clears up on its own, but it may be worth checking in with a healthcare professional if lasts more than a week.

3. Dental problems

Pain on one side of your jaw can often be traced to dental or oral health concerns.

Common dental problems that cause jaw pain include:

If dental issues are to blame, you’ll likely have additional symptoms, such as:

Facial swelling and fever along with severe tooth pain may indicate an abscess. You may want to contact a dentist or healthcare professional right away for these symptoms, especially if breathing and swallowing become difficult.

While uncommon, rare issues may lead to pain on one side of your jaw. If there isn’t a clear reason for your pain, a healthcare professional may want to rule out these causes.

4. Heart attack

Generally, jaw pain on one side isn’t cause for immediate concern. But in rare cases, it can be an early sign of a heart attack. In this case, you may feel it spreading from your chest to your jaw.

Anyone can experience this symptom, but it does occur more commonly in women, according to the American Heart Association.

If you’re having a heart attack, you’ll likely have some other signs along with jaw pain, including:

  • pressure or pain in your chest that goes away when you rest but keeps coming back
  • tightness, pain, and pressure in your chest and arms, which can spread to your jaw, neck, back, and stomach
  • heartburn or indigestion
  • shortness of breath
  • nausea, vomiting, and stomach pain
  • extreme tiredness
  • dizziness and lightheadedness
  • sudden cold sweats

These symptoms can develop suddenly or come on slowly, over several hours or days. If your jaw pain is accompanied by some of these symptoms, you may need emergency treatment.

5. Trigeminal neuralgia

This chronic condition generally results from abnormal pressure on the trigeminal nerve. This pressure can prevent the nerve from functioning properly, leading to severe pain. An injury or brain abnormality can also cause the condition.

Trigeminal neuralgia is most common in females and people above the age of 50. The primary symptom is severe pain that usually occurs on one side of your face.

This pain may:

  • occur when you touch your face or move facial muscles, even minimally
  • produce shooting, jabbing, or shock-like sensations
  • feel like a constant ache or burn
  • cause twitching in your face
  • occur in episodes that last for seconds or minutes
  • occur in your lower jaw, cheek, or mouth
  • become more severe over time

Pain is often brief but excruciating. It may not respond to over-the-counter medications, but a healthcare professional can recommend other treatments, including prescription medication.

6. Osteomyelitis

Osteomyelitis is an uncommon but serious type of bone infection that develops when bacteria enter the bone.

Your jawbone could become infected after dental surgery, if you have a serious dental health issue, or if your mouth is injured in some way. Conditions that affect your immune health can also increase your risk.

This infection can spread and cause bone death. Prompt treatment with antibiotics can help prevent serious complications, so it’s important to get medical care if you have:

  • worsening pain in your jaw
  • fever
  • swelling or tenderness in your teeth or jaw
  • redness or warmth at the painful area
  • tiredness or fatigue
  • bad breath
  • trouble opening and closing your mouth due to pain and swelling
  • numbness in your jaw, lips, or mouth

7. Tumors and cysts

These two types of growths differ. Tumors are masses of tissue and cysts generally contain fluid. Either can cause pain in your jaw, though both are somewhat rare.

Often, they aren’t cancerous, but they can still have an impact on oral health. They may grow quickly, causing your teeth to move out of place and destroying bone and tissue in your jaw and mouth.

Some of the more common tumors and cysts include that can affect your mouth include:

Not all cysts or tumors cause symptoms, but you could experience the following, along with persistent pain in your jaw:

  • red or white patches in your mouth
  • open or bleeding sores
  • a lump or growth you can feel
  • lingering soreness or hoarse feeling in your throat
  • trouble swallowing or moving your jaw
  • tissue growth around teeth
  • jaw or facial swelling

Treatment depends on the type of growth and its cause, but early detection and medical care can improve the chances of successful treatment.

8. Salivary gland stones

Salivary gland stones can cause swelling and jaw pain. Obstruction of the duct by a stone can potentially lead to a bacterial infection or an abscess.

Symptoms can include:

  • pain with eating
  • swollen lymph nodes
  • discharge
  • reddening of the surrounding area

Treatment can depend on the size and location of the stone but involves different procedures for removal. If you have signs of a bacterial infection, a doctor may also prescribe antibiotics.

If you have mild or temporary pain in your jaw, you may not need medical treatment. If the cause isn’t serious, pain usually improves once the issue clears up.

In the meantime, these approaches can help you manage it:

  • Use heat: Heat may help relax your muscles and relieve aches and stiffness.
  • Use ice or cold compresses: Cold compresses can help numb pain and may be particularly helpful if you’re also experiencing swelling.
  • Try nonprescription pain relief: Acetaminophen (Tylenol), ibuprofen (Advil), and other over-the-counter pain medications can help relieve pain temporarily. Be sure to follow the dosage instructions on the package. If the recommended dose isn’t effective or you need to take pain relievers for more than a few days, it’s best to see a healthcare professional.
  • Rest your jaw when possible: Choosing foods that don’t require a lot of chewing can help you avoid overworking your jaw muscles.
  • Try massage: A healthcare professional, physical therapist, or massage therapist can use massage therapy to help release pain and tension in your jaw. You can also learn how to use some techniques on your own. They may be especially helpful for TMJ disorders.
  • Try to relax: If your jaw pain comes from grinding or clenching your teeth, relaxation techniques can help you avoid using this as a stress response. Relaxing your muscles can also help relieve pain.
  • Change your sleeping position: If you always sleep on the same side or sleep with your hand under your jaw, this could put pressure on your muscles. Switching the side you sleep on could help your pain. Even if your pain has a different cause, sleeping on the other side could help relieve pain at night.

If your jaw hurts because of an underlying cause, treating that health issue may help resolve your symptoms.

Although jaw pain typically isn’t always serious, other symptoms you experience along with it could point to a more serious condition that requires treatment.

You may want to consider seeing a healthcare professional or dentist if the pain sticks around for more than a few days or seems to clear up and come back.

Other signs it may be time to get a medical professional’s opinion include:

  • You have trouble eating, drinking, swallowing, or breathing.
  • Pain makes it difficult to move your mouth as you usually would.
  • You have swelling or a fever that doesn’t go away.
  • You have a high fever.
  • You have severe pain that suddenly goes away after a burst of salty liquid that tastes and smells unpleasant, which can occur with a dental abscess.

When it’s serious

In rare cases, jaw pain may indicate a cause that requires prompt treatment. These symptoms can include:

  • high fever
  • extreme pain
  • swelling that affects your ability to breathe and swallow

A high fever, extreme pain, or swelling that affects your ability to breathe and swallow are all serious symptoms that require urgent or emergency care.
