"Why Does My Jaw Hurt After an Airbag Deployed After a Car Accident?"

If your jaw hurts after your airbag deployed in a car accident, you’re not alone. In my experience seeing car accident patients over the past 23 years I would estimate that 30% of car accident injured patients experience jaw pain. Many people expect neck pain or back pain after a collision, but they are surprised when they begin experiencing jaw pain, difficulty chewing, headaches, or clicking in the jaw. Airbag deployment can create significant forces throughout the head, neck, and face, leading to injuries that may not be immediately apparent.
At Back In Action Injury Chiropractic in Bellevue, Washington, we specialize in evaluating patients following motor vehicle collisions. Jaw pain after an airbag deployment is one of many injuries that can develop even when there are no obvious cuts or broken bones.
Can an Airbag Cause Jaw Pain?
Yes. Airbags are designed to save lives by reducing the risk of severe head and chest injuries, but they deploy incredibly fast—often in less than 1/20 of a second. During deployment, your head and neck are subjected to sudden acceleration and deceleration forces.
Your jaw may be injured if:

• The airbag strikes your face directly.
• Your jaw forcefully closes or shifts during impact.
• Your head rapidly snaps forward and backward (whiplash).
• Your chin impacts the steering wheel or dashboard before the airbag fully inflates.
• The muscles and ligaments supporting the jaw are overstretched.

Even if your jaw wasn’t struck directly, the forces of the collision can place significant stress on the temporomandibular joints (TMJs).
Common Jaw Injuries After an Airbag Deployment
TMJ Sprain or Strain
The temporomandibular joints connect your jawbone to your skull. A sudden impact can strain the ligaments and surrounding muscles, leading to pain, stiffness, and difficulty opening or closing your mouth.
Muscle Injuries
The muscles responsible for chewing can become strained during a collision. These injuries often cause tenderness around the cheeks, temples, and jawline.
Joint Irritation
The cartilage inside the TMJ can become irritated or inflamed after trauma. Some patients notice clicking, popping, or grinding sensations that were not present before the accident.
Whiplash-Related Jaw Pain
Many people don’t realize that whiplash injuries frequently contribute to jaw pain. The muscles of the neck and jaw work together, so an injury to the cervical spine can create referred pain into the jaw and face.
Symptoms to Watch For
Jaw injuries don’t always appear immediately after a collision. Adrenaline can mask pain, and symptoms may develop over the next several days.
Common symptoms include:

• Jaw pain while chewing
• Clicking or popping when opening your mouth
• Difficulty opening your mouth fully
• Locking of the jaw
• Pain in front of the ears
• Ear fullness without an ear infection
• Facial soreness
• Headaches
• Neck pain
• Pain when yawning
• Difficulty biting into food
• Teeth that suddenly feel like they don’t line up correctly

If these symptoms develop after a motor vehicle collision, they should be evaluated by a healthcare professional.
Why Jaw Pain Shouldn’t Be Ignored
An untreated jaw injury can become a chronic problem. Persistent inflammation or altered movement of the TMJ may lead to ongoing discomfort, headaches, difficulty eating, and reduced quality of life.
Jaw injuries are also commonly associated with:

• Whiplash
• Neck pain
• Concussions
• Headaches
• Upper back pain
• Muscle tension

A comprehensive examination helps determine whether your jaw pain is occurring by itself or as part of a broader injury pattern.
How Chiropractic Care Can Help
At Back In Action Injury Chiropractic, we perform a thorough evaluation after a car accident to determine the source of your symptoms. This includes assessing not only the jaw but also the cervical spine, muscles, posture, and overall biomechanics.
Depending on your condition, treatment may include:

• Gentle chiropractic care when appropriate
• Soft tissue therapy
• Muscle rehabilitation
• Range-of-motion exercises
• Postural correction
• Home care recommendations
• Coordination with your dentist, oral surgeon, or other healthcare providers if advanced imaging or specialty care is needed

Every patient is different, and treatment recommendations are based on your individual examination findings.

In many cases, yes. If your automobile insurance policy includes Personal Injury Protection (PIP), medically necessary evaluation and treatment related to injuries sustained in a motor vehicle collision may be covered regardless of who caused the accident.
Our office is experienced in helping patients navigate Washington PIP claims so they can focus on recovery.
When Should You Seek Treatment?
You should schedule an evaluation if you experience:

• Jaw pain after an airbag deployment
• Difficulty chewing
• Clicking or locking of the jaw
• Headaches after a collision
• Neck pain with jaw discomfort
• Facial soreness that develops after the accident

Prompt evaluation can help identify injuries early and guide appropriate treatment before symptoms become more difficult to manage.

Frequently Asked Questions

Can jaw pain start several days after a car accident?
Yes. It’s common for symptoms to appear hours or even days after a collision as inflammation develops and adrenaline wears off.

Can whiplash cause jaw pain?
Yes. The muscles and joints of the neck and jaw are closely connected, and whiplash can contribute to TMJ pain and dysfunction.

Should I see a chiropractor for jaw pain after a car accident?
A chiropractor experienced in treating motor vehicle collision injuries can evaluate whether your jaw pain is related to whiplash, TMJ dysfunction, muscle strain, or another injury. If your condition requires imaging or referral to another specialist, appropriate recommendations can be made.

Is jaw pain after an airbag deployment normal?
Jaw pain is not unusual after an airbag deploys, but it should not be ignored. A proper evaluation can help determine the extent of the injury and the most appropriate course of treatment.
