Why Does My Jaw Keep Popping? TMJ, Sleep Apnea & More

Does your jaw pop every time you open your mouth to yawn or take a bite of food? Jaw popping is pretty common, but it can range from a minor (if annoying) quirk to a symptom of something more serious.

This article will explore all the reasons why your jaw might be popping, when you should worry about it, and what you can do to address it.

First, let’s quickly review two key concepts: TMJ and TMD. The temporomandibular joint (TMJ) connects your lower jaw to your skull and allows you to move your jaw. Temporomandibular joint disorder (TMD) is a potential cause of jaw popping.

What is TMJ and TMD?

If your jaw clicks or pops, you might wonder if you have “TMJ.” But what does that mean?

Understanding the temporomandibular joint (TMJ)

The temporomandibular joint or TMJ is the hinge joint that connects your lower jaw (the mandible) to the temporal bone of your skull. You have two TMJs, one on each side of your face. The TMJ lets you move your jaw in many different directions so you can open and close your mouth, chew, and talk.

Between the bones of the joint is a cartilage disc that acts as a cushion and allows for smooth movement.

Defining temporomandibular disorders (TMD)

Temporomandibular disorders (TMD) are a group of conditions that affect the TMJ and the muscles and tissues around it.

Jaw popping is often a symptom of TMD.

Common Causes of Jaw Popping

So, what’s making your jaw sound like a bowl of Rice Krispies? Here are some of the most common culprits:

Joint Misalignment and Dysfunction

Your temporomandibular joint (TMJ) has a cartilage disc that cushions the bones. If that disc gets out of whack – displaced or misaligned – it can cause clicking or popping when you move your jaw. This misalignment can happen because of strain or injury to the TMJ.

Muscle imbalances and tension around your jaw can also play a role. When those muscles are tight or not working together correctly, it can mess with the way your joint functions and lead to those annoying pops.

Behavioral Factors and Habits

Think about your daily habits. Do you grind your teeth or clench your jaw? This habit, called bruxism, puts a lot of strain on the TMJ, especially when you’re stressed or anxious.

Also, frequent gum chewing or other repetitive jaw movements can overload the joint. Try to avoid activities that involve opening your mouth really wide or repeating the same motions over and over.

Injury and Trauma

A direct hit to the jaw, like from a fall or accident, can definitely mess things up. It can cause misalignment or damage the joint structures themselves.

Even whiplash or other neck injuries can affect your TMJ. Neck injuries can lead to muscle imbalances that then affect how your jaw works.

Medical conditions linked to jaw popping

Sometimes, a popping jaw is a sign of an underlying medical issue.

Arthritis

Arthritis in general, and osteoarthritis and rheumatoid arthritis in particular, can affect the temporomandibular joint (TMJ), the hinge that connects your jaw to your skull. This can cause pain, stiffness, and — you guessed it — popping.

Osteoarthritis happens when the cartilage in your joints breaks down. Rheumatoid arthritis, on the other hand, is an autoimmune disease.

Sleep apnea

Sleep apnea can cause teeth grinding and jaw clenching while you’re asleep, which puts a lot of strain on the TMJ. Over time, that strain can lead to your jaw popping when you open or close your mouth.

Myofascial pain syndrome

Myofascial pain syndrome is a chronic pain condition that affects the muscles and the fascia (the connective tissue that surrounds the muscles). Trigger points, or knots, can develop in the jaw muscles, which can affect the TMJ and lead to popping.

Malocclusion

Malocclusion simply means that your teeth aren’t aligned correctly. This misalignment can contribute to TMJ problems and, ultimately, a popping jaw.

When to see a healthcare provider

If your jaw pops every once in a while, and you don’t have any pain, there’s probably nothing to worry about. But you should seek medical care from a dentist or TMJ specialist if you notice:

  • frequent popping
  • pain in your jaw, face, or neck
  • trouble moving your jaw or locking
  • headaches
  • earaches
  • swelling near your jaw joint

It’s important to get diagnosed and treated early. Addressing TMJ and related conditions when they first appear can prevent the issue from getting worse and requiring more complex, expensive treatments.

Treatment Options for Jaw Popping

So, your jaw is popping. What can you do about it? Here are a few options, starting with what you can do at home.

Home Remedies

  • Over-the-counter pain relievers. An NSAID (nonsteroidal anti-inflammatory drug) like ibuprofen can reduce inflammation and pain.
  • Heat and ice packs. Try alternating ice and moist heat. Ice packs for 10 to 15 minutes, followed by a warm compress for 5 minutes, may help.
  • Gentle jaw exercises and stretches. You can find examples of jaw stretches and exercises online.
  • Dietary changes. Baby your jaw for a while by avoiding hard or crunchy foods.

Professional Treatments

If home remedies aren’t enough, it may be time to consult with your dentist or doctor.

  • Mouthguards and splints. A custom-made mouthguard can stabilize your jaw and reduce teeth grinding, which may be contributing to the problem.
  • Physical therapy. A physical therapist can help you improve jaw mobility and reduce muscle tension in your face and neck.
  • Medications. Muscle relaxants or corticosteroids may offer some relief.
  • Surgery. In severe cases, surgery may be necessary to correct the problem.

Frequently Asked Questions

Is it normal for your jaw to crack a lot?

A little bit of jaw popping or clicking now and then isn’t usually a cause for concern. Many people experience occasional joint sounds without any pain or other symptoms. But, frequent cracking, popping, or grinding in your jaw, especially when accompanied by pain, stiffness, headaches, or difficulty opening or closing your mouth, is something you shouldn’t ignore.

It could indicate a problem with your temporomandibular joint (TMJ), the hinge connecting your jawbone to your skull. TMJ disorders (TMD) can have various causes, including jaw injuries, teeth grinding, arthritis, or even stress. If the popping is persistent or bothersome, it’s best to consult a dentist or doctor. They can evaluate your jaw, determine the underlying cause, and recommend appropriate treatment options.

These options range from conservative measures like lifestyle changes and physical therapy to more advanced treatments if needed. Don’t let jaw popping disrupt your daily life – getting it checked out can bring relief and prevent further complications.

In Closing

As we’ve seen, jaw popping can result from various causes, some more serious than others. While an occasional click or pop might not be cause for alarm, persistent or painful popping warrants a visit to a professional.

Lifestyle modifications can also play a big role in managing your jaw health. Managing stress, maintaining good posture, and avoiding habits like teeth grinding and gum chewing can prevent or ease jaw popping.

Ultimately, the best approach is to consult with your dentist or a TMJ specialist for personalized advice and the right treatment plan for you.
