Why Does My Jaw Hurt? (Top Reasons)

Why does my jaw hurt? Your jaw also holds your teeth and gums, which can be sensitive to heat, cold, or pressure. They can also get infected if you don’t keep them clean.

Why Does My Jaw Hurt?

Jaw pain may indicate a simple toothache or perhaps something more catastrophic like a heart attack.

The temporomandibular joints, sometimes referred to as TMJs, is where your jawbone, also known as a mandible, joins your skull. You can open and close your lips using these joints, which are located directly in front of your ears.

Why Does My Jaw Hurt?

Almost everyone experiences jaw pain at some point in their lives. The causes of jaw pain range from straightforward issues that can be resolved to complicated issues that need a complex therapeutic approach.

The following are a few reasons for jaw pain.

TMJ Disorders

The joint that links your skull and jaw is impacted by temporomandibular joint (TMJ) disease. The bones in this joint are separated by a disc, which aids in appropriate movement.

You could feel discomfort and other symptoms, including tenderness, earaches, clicking or popping when opening your mouth, and trouble opening and closing your mouth if it gets misaligned or the joint is injured.

When germs invade the bone, they cause osteomyelitis, a rare but dangerous type of bone infection.

If you undergo dental surgery, suffer from a significant dental condition, or sustain a mouth injury, your jawbone may get infected. Your risk may also rise due to illnesses that compromise your immune system.

This infection has the potential to spread and kill bones. Used promptly, antibiotics can help prevent major consequences. So it’s important to get medical care if you have:

1. Worsening pain in your jaw

2. A fever

3. Swelling or tenderness in your teeth or jaw

Oral Health Problems

One-sided jaw pain can occasionally be a sign of more serious oral health issues.

Cavities, an abscessed tooth, gum disease, tooth decay, the development of wisdom teeth, missing or crooked teeth, and clenching or grinding your teeth are a few frequent conditions that result in jaw pain.

Joint Problems

Your temporomandibular joints may be affected by rheumatoid arthritis, a kind of arthritis.

Because it is an autoimmune condition, your body unintentionally assaults healthy tissue, causing it to enlarge.

Your jaw may become tight and painful if it happens to the soft, spongy cartilage that maintains it moving freely.


Sinusitis can be brought on by nasal cavity inflammation. Inflammation in the nasal cavities, which are behind the cheeks, might result in pain on either one or both sides of your jaw.

This pain frequently comes with additional symptoms like nasal congestion, yellow or green mucus, facial swelling, exhaustion, and trouble tasting or smelling.


You can break or misalign your jaw just like any other bone. In most cases, taking over-the-counter painkillers or doing actions like eating soft foods will help you feel better as you recover.

But you’ll need medical attention if the discomfort won’t go away or if you can’t open and close your mouth properly.

The misalignment of teeth might occasionally also result in jaw pain. Learn more about the various overbite and jaw discomfort treatment options.


Diseases have been largely eradicated by vaccines. However, some people continue to have them, and one sign is jaw pain.

1. Mumps

It is contracted by a virus. The saliva-producing glands on the side of your mouth enlarge as a result. Jaw movement may be challenging because of the pain.

2. Tetanus

This bacterial infection enters your body through a skin wound or scratch. Your jaw muscles may feel tense or rigid as an early indicator.

Many people refer to the spasms as “lockjaw.” You could spend weeks in the hospital if you get this deadly sickness.

Should I Worry If My Jaw Hurts?

 In many cases, jaw pain does not need immediate medical attention, but sometimes it can indicate a more serious underlying condition that needs treatment. 

Anyone with severe, worsening, or persistent jaw pain should see a doctor for a diagnosis. “Why Does My Jaw Hurt?”
