jp123...thanks for the reply! What is a repo splint? I can't remember what the other type of splint was that the tmj dentist said I might have to try if this one doesn't work...but it was about $450! I am getting along better with my new splint, but must admit I really HATE the darn thing! I feel like a little old lady with dentures...arg! I don't wear it as often as I should I know, but have to take it out to eat, drink or smoke (my bad habit!) and then just too lazy or forget to put it back in...but I faithfully wear it all nite long. I still am having episodes of extreme jaw pain...especially a very stressful nite on Friday...the pain medication wouldn't hardly even cut it, but I eventually cried myself to sleep.
