TMJ stands for temporomandibular joint. It's the joint connecting your lower jaw (mandible) to your skull, and you have one on each side of your head. These joints are crucial for chewing, speaking, and yawning.
Understanding the TMJ
The TMJ is a complex joint, acting like a sliding hinge, allowing for a combination of rotational and gliding movements. Its intricate structure makes it susceptible to a range of disorders.
- Location: Located on both sides of your head, connecting your jawbone to your skull.
- Function: Enables jaw movement for vital activities such as chewing, speaking, and yawning.
- Structure: A complex joint with both rotational and gliding movements.
TMJ Disorders (TMD)
Problems affecting the TMJ are often referred to as temporomandibular disorders (TMD) or TMJ disorders. These disorders can cause pain in the jaw joint and the muscles controlling jaw movement. TMD encompasses a wide array of conditions, with symptoms varying widely from person to person. Some common symptoms include jaw pain, clicking or popping sounds in the jaw, headaches, and difficulty chewing.
- Pain: Pain in the jaw joint and surrounding muscles is a hallmark symptom.
- Movement: Difficulty opening or closing the mouth, or jaw clicking or popping sounds are common.
- Headaches: TMD can sometimes lead to headaches, often around the temples or forehead.
