Does anyone have any tips on how to cope with or prevent bruxism? I've had it going for years now. Recently I've been having daily tension headaches that last almost all day. I've been to the GP and they want to do tests to rule out other things. However, tonight I've woken with a severely clenched jaw. I was shocked at how tightly clenched it was. It might just be due to stress as yesterday was a very stressful day but it got me wondering if that could be the cause of my headaches. My dentist charges over £300 for the mouth guard which I can ill afford and the dentist won't accept a payment plan. I've tried the Dentek one in the past which didn't fit despite the boiling process and it made me gag. I've seen jaw stretching devices and hemp muscle relaxants and wonder how effective they are. Beyond that I'm not sure what else may help. I did have a specially made mouth guard years ago but I wore it down. It did work to some extent though. Any advice would be much appreciated.
