Dental Occlusion (Good or Bad Bites) can cause Tooth Grinding if the occlusion is off or bad. In fact when I started treating TMJ patients in my private office 15 years ago, I treated every patient with the concept that Bad Bites is THE factor causing TMJ.

After further training and after a few years of Private Practice, I saw and learned that other factors cause the problems with TemporoMandibular Joint dysfunction.

In my Private Practice, I correct TMJ patients' Dental occlusion about 15% of the time. I recommend Dental Occlusion correction somewhere in the 20-25% of the time. But some patients can go without the correction and wear a well adjusted TMJ Splint when they sleep, and they'll be fine.

As long as the patient understands what's causing the TMJ symptoms, I'm OK with that as their Doc. It's mainly the patients with severe cases that want me to correct their bite.

Bad Bites in the TMJ Dentists' world is a bit different than other people's concept of what a Bad Bite or a Good Bite is...

A true Good Bite is when the Condyle (the upper most part of the mandible) is seated in the most upper and forward part of the TMJ (joint), and the teeth all mesh beautifully together when biting (when the teeth are together).

And It's when the condyle is in the correct place in the joint and the teeth do not mesh together nicely that you have a Bad Bite.

That's the first requirement of having a good bite. Then there's the functional part of having a good or bad bite. If the canines touch as you move your lower jaw any direction and lift the back teeth apart so that they do not touch during another movement, then you have a good bite.

When that criteria does not happen, you have a certain degree of a Bad Bite. Beit minor or severe, depending on the range of discrepancies.

It is only when a TMJ Dentist does TMJ Splint Therapy that it is possible to accurately diagnose that relationship between the condyle and it's joint space. You can not tell just by examining a patients' mouth and saying whether the Occlusion is good or not. You can make a good guess when you do have a good bite, but not for sure.
