TMJ Disorders
What is the Temporomandibular Joint?
There are two temporomandibular joints that connect the left and right sides of the lower jaw to the temporal bone. Both joints and their associated muscles, ligaments, and tendons work together to allow for all manner of oral function as the jaw moves up and down, front to back, and from side to side. Containing a shock-absorbing, soft disc that sits between the rounded condyles of both sides of the lower jaw and the corresponding concavities in the skull’s temporal bone, the TMJ makes chewing, speaking, yawning, and all jaw movements possible.
Since the TMJ is a joint with both up and down hinge-like movements, as well as side to side and front to back sliding motions to perform, it is often considered one of the most complicated joints in the body and one of the most difficult to treat when problems arise.
