Hello, complicated question with many options for you. The first part would be yes, the actual fillings being placed does not really aggravate a preexisting condition, but opening your jaw wide for extended periods will. You need to go to a dentist that has a keen understanding of tmj because the treatment will differ depending on the cause of the tmj condition. There are many options, but again we would need to know the reason you have the tmj condition in the first place. My sincere hope you find someone who can help you!
