Is the main cause of tmj grinding ones teeth? I know a bad bite can be a cause but do the majority of people with TMJ grind their teeth at night. TIA

Hi I think my tmj is because im stressed all the time and move my jaw back and forth without thinking Im 53 and waiting to have a double jaw replacement and im terrified. How bad is yours? Im from the uk where are you from judy.

Mine certainly is from grinding at night which ive done since I was a young child apparantly. Im 31 now but I also notice I clench my teeth and also move my jaw around a lot.

mine is from clenching when im sleeping and stressed and missing all my bottom teeth bar on on the left the one i have left has actually fallen over now because theres nothing holding it up!!

so mine is caused by over use of the muscles on the right because i eat everything on the right side, my cheak muscle is very well developed on this side so is my neck muscles you can see the diffrence just looking close up :cool:

Mine from grinding, clenching, stressed, open bite, dislocated disk.

In my case, bruxism is absolutely the prime culprit. What triggered the bruxism? Orthodontics when I was 13.
