The best thing to do is to find a dentist that treats TMJ disorders and/or Bruxisim. Many general dentists have training in it.
I hope that this helps. If you have any further questions about this issue, just drop a line and let me know exactly what is happening with your condition and how it affects you.
Take care, keep smiling and floss the teeth that you want to keep! :)
Good luck and if it happens or is continuing to be loose, drop by and have it checked out.
