There are many reasons why your teeth and jaws do not occlude (come together) in an acceptable position, such as fillings or bridges that have shifted over a period of years, orthodontics, developmental defects, oral surgery, trauma, poor bite, or clenching.
In occlusal equilibration, the tops of your teeth are reshaped. This is done to alleviate pressure on individual teeth. This therapy allows your lower jaw to function in a natural hinge in relation to the jaw without improper influence from teeth.
