The TMJ acts as a sliding hinge connecting the jawbone to the skull. When issues arise, they can cause unpleasant symptoms such as jaw pain, difficulty chewing, and a popping sound when opening the mouth.

Among these symptoms, many people wonder whether TMJ disorders can also cause ear pain or tinnitus, characterized by ringing or buzzing sounds in the ear. Can TMJ cause these problems? Let’s take a closer look.

What Is the Connection Between TMJ and Ear Pain?

Ear pain is a common symptom for people suffering from TMJ disorders. The temporomandibular joints are located close to the ear, which can lead to referred pain. Referred pain occurs when an issue in one part of the body causes discomfort in another, seemingly unrelated part.

In this instance, problems with the TMJ can cause pain that is perceived in the ear area. The earache resulting from TMJ disorders can range from mild discomfort to severe pain, either intermittently or persistently.

Many people are surprised to find that ear pain is a common symptom of TMJ. In one study, 46% of patients with ear pain were also diagnosed with TMJ dysfunction [1].

TMJ and Tinnitus

Tinnitus, often described as a ringing, buzzing, or hissing noise in the ears, can be another frustrating symptom of TMJ disorders. Research shows a strong connection between TMJ disorders and tinnitus: 60% of TMJ patients experience tinnitus, significantly higher than the 15-30% rate seen in the general population [2].

The exact relationship between TMJ disorders and tinnitus is not fully understood, but experts suspect the following connections between the two issues:

• Shared nerve pathways. The nerves that provide sensation and control the muscles of the TMJ also have connections to the auditory pathways. Dysfunction in these nerves due to TMJ issues could lead to tinnitus.
• Muscle tension. The muscles surrounding the TMJ can become tense or overworked in response to joint problems, potentially affecting the tiny muscles in the ear responsible for stabilizing ossicle movement, contributing to tinnitus.
• Inflammation spread. Inflammation within the TMJ or nearby ligaments can extend to the region of the ears, altering the ear’s function.

When to Seek Professional Help

If you suspect that you might have a TMJ disorder and experience symptoms like ear pain or tinnitus, it’s crucial to consult a healthcare professional for a comprehensive evaluation. Often, dentists who specialize in TMJ disorders can provide insights into the best course of action tailored to your specific condition [3]. There are many options for treating TMJ and tinnitus that can help reduce your symptoms and improve your quality of life.

Biting Your Nails Can Cause Tooth Enamel Damage

The main component of your fingernails is keratin, which is a type of protein that also constitutes your hair. This hard substance has the ability to cause teeth to shift, fracture, and even to wear away tooth enamel over time [1]. Your teeth may be more susceptible to these types of injury if they already have existing damage, such as a fracture, decay, or gum disease, which can cause loose teeth.

Nail Biting Affects Plaque and Oral Bacteria

Did you know that nail biting also affects the amount of plaque in your oral cavity, as well as the balance of bacteria [2]? Since your hands and fingers are exposed to a variety of germs throughout the day, compulsively biting your nails can expose your oral cavity to bacteria it would normally wouldn’t be exposed to.

People who bite their nails also have higher levels of plaque in their mouths, which is the sticky substance that coats teeth throughout the day in between brushing. Nail biting also exposes people to more bacteria that could cause both oral and systemic infections, including E. coli [2].

It May Even Increase Your Risk for TMJ Problems

Another consequence of nail biting for your smile is that it could increase your risk for problems with your jaw. Your temporomandibular joint (TMJ), which is located near your ear on either side of your head, allows your jaw to function properly. Overuse of this joint can cause discomfort and inflammation, which could lead to what are commonly referred to as TMJ disorders. Some evidence shows that chronic nail biting can increase your risk for TMJ disorders or aggravate an existing problem with your jaw[3].

Do You Bite Your Nails?

Nail biting is generally not considered to be a helpful or healthy habit, especially since it can damage teeth, expose you to dangerous bacteria, and overwork your jaw. Whether you’re an occasional nail biter or have had the habit for years, there are ways to stop. From keeping your nails short to identifying your triggers, consider curbing your nail biting habit to support your oral health and reduce your risk for getting sick!

Stress Can Lead to Bruxism

The TMJ and stress are closely related through the trigeminal nerve, which is affected by muscle tension. When you experience stress, your muscles tense in what’s known as our fight or flight response. When there’s no resolution to this physical response, you may grind your teeth.

Bruxism, the technical term for teeth grinding, is a common side affect of stress. People who grind their teeth often create symptoms of TMJ disorders, such as a sore jaw, tight muscles, and facial pain. This tension can often lead to headaches. Symptoms from stress and TMJ disorders overlap each other. Bruxism may also be a symptom of a problem with your TMJ, as the top and bottom parts of your jaw may not fit together correctly.

Tense Muscles Cause Headaches

Headaches are a common symptom of TMJ disorders. However, if you’re experiencing tight neck or face muscles from stress, this could be linked to your jaw pain. If you’re also experiencing joint popping or clicking, a TMJ disorder may be present. A sore jaw or painful chewing could mean your joint is inflamed and not working as it should. This can also lead to headaches, much like stress does. TMJ disorders can cause stress as well as be caused by stress.

Clenching your jaw or experiencing stress could actually cause a problem with your TMJ. Stress can aggravate TMJ symptoms, whether it’s the stress of a physical illness or the mental and emotional stress of a hard day at work. Even if you don’t have a TMJ problem, stress could lead to the onset of issues due to tension and inflammation.

How to Stop the Effects of TMJ and Stress

Stress can create a vicious cycle with your TMJ. If you have a preexisting problem with your jaw joint, stress can make it worse. Even if your jaw is healthy, it can actually cause a TMJ disorder. The key here is to properly manage stress to reduce the chances of problems with your TMJ.

Talk to your doctor about what types of relaxation techniques you can do. Exercise, meditation, and even simple activities such as talking to a friend or reading a book can help you reduce stress. If you’re grinding your teeth or have symptoms of a problem with your TMJ, talk to your dentist about how you can protect your teeth and relax the muscles.

Stress hugely impacts your health, especially your TMJ! Stress can also influence your risk of other health problems such as heart disease and high blood pressure. By properly managing your stress, you can help combat any TMJ problems you’re having. Talk to your dentist for more information!
