Why is my dental work failing?

 
There are many causes that result in dental treatment failure. Common causes that people often hear of are wear and tear, recurrent cavities, defective restoration, or poor dentistry. The one that people hear of the least and the bottom line cause that results in many premature failures of perfectly good dental restorations is the lack of bite stability.
Our jaw is a complex chewing machine, with the lower jaw being the moving part that meets the skull at the Temporal Mandibular Joint, TMJ. This joint connects the temporal bone of of the skull with the Mandible bone of the jaw. The jaw is supported by 5 groups of muscles that help the jaw movement and our teeth are the stopping points in the chewing cycle. Stability of the joint and muscle is achieved when our bite is balanced and teeth come together at a certain muscle resting length.
