Jaw Pain Causes: TMJ, Grinding & More
By Dr. Raheel Thobani, DMD
Waking up with a sore jaw, a dull headache, or noticing a clicking sound when you chew; these are common yet disruptive experiences. If you're dealing with persistent jaw pain, you're likely trying to connect the dots: is it from clenching your teeth? Is it a problem with the joint itself? Or is it something else entirely?
Identifying the root cause of jaw pain is the first and most crucial step toward achieving lasting relief. At Smyrna Dental Studio, we specialize in diagnosing and treating the complex issues that affect the jaw. This guide will explore the most common causes of jaw pain and explain how a comprehensive dental evaluation can help you find relief.
Unpacking the Common Culprits Behind Your Jaw Pain
Jaw pain is often multifactorial, but it typically stems from a few key issues that a dentist is uniquely qualified to identify.
1. Teeth Grinding and Clenching (Bruxism)
This is one of the most common causes of jaw pain. Bruxism is the involuntary grinding or clenching of teeth, and it often happens subconsciously while you sleep. This puts immense pressure on your jaw muscles and temporomandibular joint (TMJ).
Signs You Might Be a Grinder: Waking up with a sore, tired jaw; dull headaches; and flattened, chipped, or worn-down teeth.
2. Temporomandibular Joint Disorder (TMD)
While many people use the term "TMJ" to describe jaw pain, the TMJ actually refers to the joint itself. The condition that causes pain and dysfunction in the joint is called Temporomandibular Disorder (TMD). This can be due to inflammation, an improper bite, arthritis, or a disc moving out of place within the joint.
Signs of a Joint Problem (TMD): A clicking, popping, or grating sound when you open or close your mouth; your jaw locking open or shut; and pain directly in front of your ear.
3. Other Dental Issues
Sometimes, jaw pain isn't directly related to the muscles or joint but is a symptom of another dental problem.
A Misaligned Bite (Malocclusion): When your teeth don't fit together correctly, it can strain your jaw muscles and joints every time you chew.
A Dental Abscess or Severe Cavity: An infection in a tooth, especially a molar, can cause pain that radiates into the jaw.
How a Dentist Diagnoses Jaw Pain
A self-diagnosis is nearly impossible due to the overlapping symptoms. A proper diagnosis is the key to effective treatment. At your consultation, we will:
Perform a thorough clinical exam, feeling the muscles of your head and neck and listening to the joint as you open and close.
Check for signs of wear and tear on your teeth, which is a classic sign of bruxism.
Assess your bite to see how your teeth come together.
Take digital X-rays or a 3D scan to get a clear view of your jaw joint and the surrounding structures.
FAQs: Your Questions About Jaw Pain
Q1: What's the difference between TMJ and TMD? This is a great question. TMJ is the anatomical term for the Temporomandibular Joint, which connects your jaw to your skull. TMD stands for Temporomandibular Disorder, which is the actual medical condition that causes pain and dysfunction in the joint and surrounding muscles.
Q2: Can I just buy a night guard from the drugstore for my grinding? It is not recommended. Over-the-counter "boil-and-bite" guards are not custom-fitted. They are often bulky, can be uncomfortable, and in some cases, can even worsen your bite by holding your jaw in an unnatural position. A professionally made custom night guard from our Smyrna office is fabricated from a precise model of your teeth, ensuring a perfect and comfortable fit that protects your teeth and allows your jaw to rest in a neutral position.
Q3: My jaw only hurts when I'm stressed. Do I still need to see a dentist? Yes. Stress is a very common trigger for jaw clenching and teeth grinding. While managing stress is important, the physical act of clenching is what's causing the damage to your teeth and straining your muscles. A custom night guard can protect your teeth and jaw from the physical effects of stress-induced clenching.
Q4: My jaw clicks but it doesn't hurt. Should I be concerned? Painless clicking is common and not always a problem. However, it can be an early sign of a developing joint issue, like a displaced disc. It's a good idea to have it evaluated during your regular checkup. If the clicking is ever accompanied by pain or your jaw gets stuck (locked), you should seek an evaluation immediately.

Jaw pain is not something you have to endure. It's a complex issue with a variety of potential causes, but a proper diagnosis is the first step toward finding a lasting solution. Ignoring the symptoms can lead to worsening pain, damaged teeth, and a decreased quality of life.
