My dentist just told me about a recent study that was done in Texas in which they were trying to find some of the causes of TMJ. This could have had my name on it. One case study was with a patient who had braces when they were younger and had teeth pulled in the process. They found that over the years the teeth try to shift back to their original position. This can go on for years without a problem then TMJ can be triggered all of a sudden even by the smallest event. They have an extensive treatment plan which includes the adjustments to the teeth which I had. I have heard people speculate about the relationship of braces and TMJ but never heard of an actual study that confirmed it.
