If you’ve been experiencing jaw pain, clicking sounds when you open your mouth, or persistent headaches, you might be dealing with temporomandibular joint disorder, commonly known as TMJ or TMD. At Nivedita Nijhawan, DDS, in Fresno, CA, we frequently see patients seeking relief from this uncomfortable condition. Understanding what causes TMJ is the first step toward finding effective treatment and getting back to comfortable daily living.
What Is TMJ Disorder?
The temporomandibular joint acts as a sliding hinge connecting your jawbone to your skull. You have one joint on each side of your jaw, and when these joints or the muscles controlling them become damaged or strained, TMJ disorder develops. While the exact cause isn’t always clear, several factors can contribute to this painful condition.
Physical Trauma and Injury
One of the most straightforward TMJ causes is direct trauma to the jaw or head. Car accidents, sports injuries, or any significant blow to the face can damage the temporomandibular joint or surrounding muscles. Even whiplash can affect your jaw alignment and contribute to TMD development. If you’ve experienced any facial trauma, it’s important to monitor for TMJ symptoms in the following weeks and months.
Jaw Clenching and Teeth Grinding
Jaw clenching with TMJ is one of the most common connections we see in our practice. Many people unconsciously clench their jaw or grind their teeth, especially during sleep or periods of high stress. This constant pressure puts tremendous strain on the temporomandibular joint and can wear down the protective cartilage. If you wake up with jaw soreness or your partner mentions hearing grinding sounds at night, this could be a significant factor in your TMJ symptoms.
Arthritis and Joint Diseases
Like other joints in your body, the temporomandibular joint can be affected by arthritis. Both osteoarthritis and rheumatoid arthritis are among the TMD risk factors that can cause the joint cartilage to deteriorate. When this protective cushioning breaks down, the bones may rub together, causing pain, stiffness, and reduced mobility in your jaw.
Structural and Alignment Issues
Sometimes what causes TMJ relates to how your jaw is structured or aligned. A misaligned bite, where your upper and lower teeth don’t fit together properly, can place uneven stress on the temporomandibular joint. Congenital conditions affecting jaw development or previous dental work that altered your bite can also contribute to TMD over time.
Stress and Muscle Tension
Mental and emotional stress ranks high among TMD risk factors. When you’re stressed, you might unconsciously tighten your jaw muscles or adopt tense facial expressions throughout the day. This chronic muscle tension can eventually lead to TMJ disorder, creating a cycle where pain causes more stress, which in turn worsens the condition.
Other Contributing Factors
Additional TMJ causes include:
- Connective tissue diseases that affect the joint
- Erosion or displacement of the disk that cushions the joint
- Poor posture that strains neck and facial muscles
- Excessive gum chewing or nail biting
- Hormonal factors, as women are more likely to develop TMD
