i have had rsd in my mouth for almost two years now. i am sorry you have it too. i was getting extra novacaine, then extra novacaine and laughing gas, to getting some of my teeth pulled because i couldn't take the pain, infections, dental procedures or root canals done anymore. i am looking into one last option before i think about getting all of my teeth pulled in the back and getting bridges. it's called sedation dentistry. i don't know if insurance will cover it but i figure it's worth looking into. i learned about it from others on this forum and hope maybe it might help you too. from what i understand you are put to sleep while they are working on your teeth and you don't feel or remember anything. i hope that whatever you decide to do you find some pain relief from the rsd in your mouth. sending healing thoughts and soft hugs your way.
