Hi: I found a website www.drjimboyd.com a while ago about bruxing. I had tried for some time to find out how to suppress the parafunction, but was unsuccessful. The splint I wore protected my teeth, but gave me a surface to clench more efficiently, thus causing muscle pain, headache, etc. My dentist fitted me with the NTI clenching suppression appliance about a month ago and it works. It might help someone else. So there is no misunderstanding, I have no connection with this product, nor do I profit from its sale in any way. I just found a very simple solution to a clenching problem that was causing me a lot of pain and thought it might be useful information for others who might need it. Genene
