Is bruxism from stress? most of my stress is about trying to figure out how to get rid of the bruxism!

A factor: Stress is very often a bruxing trigger but not for everyone. Honestly assess your stress levels relative to normal. If there is nothing out of the ordinary, other factors are probably involved, often related to your bite and occlusal interferences. More often people are in fact under much higher stress levels than they realize, but obviously not always. Get evaluated by a tmd focused dentist.

No: It is most likely being caused by a tmj/muscle dysfunction. Possible the upper jaw (maxillae) is too narrow or in crossbite as related to the lower jaw (mandible). This causes the muscles to not be in proper function. Then these muscles move to search for their home position. Unable to find their proper position, they keep moving and moving, and moving = bruxism. Need orthopedic or TMJ treat.

Recession: Bruxism can contribute to recession. Stop trying to manage this by yourself...it isn't working. See s pro for effective help, see a bone/gum specialist, a Periodontist. The longer you wait, the more intractable the damage.
