TMJ and TMD
Temporomandibular Joint (TMJ) and Temporomandibular Disorder (TMD) are terms commonly used in dentistry to describe issues related to the jaw joint and the surrounding muscles. These conditions can lead to pain, discomfort, and a range of symptoms that can affect a person’s daily life. In this article, we will explore what TMJ and TMD are, their causes, symptoms, diagnosis, and treatment options.
The temporomandibular joint (TMJ) is a complex hinge-like joint that connects your jawbone (mandible) to the skull’s temporal bone. It plays a crucial role in various jaw movements, such as chewing, talking, and yawning. The TMJ is supported by a system of muscles, ligaments, and a cartilaginous disk, all working together to facilitate smooth and pain-free jaw function.
Temporomandibular Disorder (TMD) refers to a group of conditions that affect the TMJ and the surrounding muscles. TMD can cause a wide range of symptoms and discomfort, impacting a person’s quality of life. It is essential to understand that TMD is not a single condition but a collection of various disorders affecting the TMJ.
