What Is TMJ/TMD? Glen Iris Guide to Jaw Joint Pain and Solutions

TMJ stands for the temporomandibular joint—the joint that connects your lower jaw to the temporal bones of your skull. You have one TMJ on each side, working together as a pair. These joints allow your jaw to move both as a hinge and to slide open wider—essential for chewing, speaking, swallowing, yawning, and even breathing.

TMJ Pain = TMD (Temporomandibular Disorders)

Because your TMJ is involved in so many daily actions, it’s prone to wear and problems. Disorders of this joint are called temporomandibular disorders (TMD), a complex and sometimes chronic condition usually causing pain in and around the jaw. TMD can limit your ability to chew, speak, and even express yourself with facial movements.

Common Causes of TMD

Tooth grinding and clenching
Misaligned upper and lower teeth
Jaw injury
Stress and anxiety
Arthritis and inflammation

Glen Iris dentists also note that those with TMD commonly report other conditions, such as chronic fatigue, headaches, endometriosis, or fibromyalgia.

Simple TMD Symptom Relief Tips

Eat soft foods to reduce jaw strain
Apply ice packs to sore areas
Avoid extreme jaw movements (wide yawning, loud singing, gum chewing)
Practice stress reduction and jaw relaxation techniques
Try gentle jaw exercises for stretching and relaxing

If your TMJ pain continues or worsens, it’s important to make an appointment with your Glen Iris dentist at Tooronga Family Dentistry for a thorough assessment and personalized treatment.
