What is TMJ?
Differences between TMJ and TMD
TMJ, the common abbreviation of “temporomandibular joint,” is the hinge that connects the upper and lower jaws to the temporal bones of the skull, and is crucial for providing the range of movement —including up and down, side to side, and back and forth— required for chewing, facial expressions, breathing, and speaking. Everyone has a “TMJ.” TMJ symptoms occur when then the joint is injured, or the muscles surrounding the joint are inflamed, causing pain and discomfort.
This pain and discomfort are referred to TMD, or temporomandibular joint dysfunction. Often, the terms “TMJ” and “TMD” become confused. Click here to view an illustrative video on the differences between TMJ and TMD.
