I have been getting treatment for some TMJ Disorder. My dentist is a TMJ Specialist. We started with a nightguard, which has alleviated my symptoms. There are a few teeth in the back that are so ground down that she wants to place some crowns and onlays. She believes this will help even more with the TMJ. Is this a normal treatment or is she just trying to give additional treatment?

Dear Avery,

Yes, crowning teeth is an accepted treatment for TMJ Disorder. In fact, in some severe cases, a dentist may suggest a full-mouth reconstruction, which will mean placing a crown on every tooth. It sounds like you just have some back teeth ground down and the fact that your nightguard has been helping is a good sign that your dentist is on the right track.
TMJ Disorder is when the temporomandibular joint is not working properly. A poorly aligned bite is one of the causes of this. Crowning the teeth can help to align your bite when done properly.
One thing to be aware of. You said your dentist is a TMJ Specialist. I want to make sure you understand that TMJ does not have a recognized specialty. However, it does require some post-doctoral training in order to do it properly. When a dentist starts messing with your bite and they do not have specific TMJ training, then you can get into trouble.
Some of the best post-doctoral training centers in TMJ are:
- The Pankey Institute
- The Dawson Academy
- Spear Education
- The Las Vegas Institute for Advanced Dental Studies
- Piper Education and Research Center
Ideally, you would be seeing a dentist who has completed coursework at one of these institutions rather than just taken a few classes. It sounds like your dentist knows what they are doing, but it never hurts to ask some questions.
