TMJs are the temporomandibular joints that connect the lower jaw, or mandible, to the temporal bones in the skull. Located in front of each ear, TMJs move in tandem as the jaw opens and closes, and rely on proper balance to repeatedly absorb bite pressure without sustaining damage.

A healthy human mouth can exert up to 200 pounds of pressure on the back molars when biting and chewing, and is designed to preserve the integrity of its components as they absorb this pressure. Teeth alignment plays a significant role in pressure displacement, and if teeth are uneven, then the mouth is off balance and certain teeth may be subjected to excessive pressure. The jaw’s joints (TMJs) and muscles will try to keep the mouth straight while biting and chewing, but the strain can eventually lead to TMJ damage and misalignment.
There are a host of issues that can arise from crooked teeth, including the diminished confidence of a less-than-appealing smile, but your teeth’s alignment is about more than looks; it’s about balance, which is a necessary component of a well-functioning mouth. Your Los Angeles orthodontist, Dr. David Alpan, believes it’s important to know the intricacies of your oral health, and enjoys helping patients find their smiles’ perfect balance through customized orthodontic treatment. Today, we explore a vital dysfunction that can result from unattended crooked teeth called TMJ disorder, which can negatively affect your smile’s integrity and the components that make it move.
Your jaw is hinged to your skull at the temporal bones in front of each ear, and the temporomandibular joints (TMJs) move in tandem as your mouth opens and closes. When healthy and perfectly aligned, your jaw displaces the pressure of your bite evenly among the joints and muscles that move it and the teeth that absorb the impact.
