Cracked my night guard already!!

I think I am under a lot of pressure lately. It is because I bite so hard at my night guard (hard plastic mold) at night, it has a big crack already!! I just got that before my trip back to HK cause I’ve been having TMJ for a year now. Every time I am under a lot of stress, I will bite my teeth so hard while I am sleeping. It sores my joints and I can’t open my month after that. So the dentist got me a night guard that I have to bite on every night. Even I wear the night guard in these couple of weeks, I still feel sore at my joints!! I can’t imagine how much it will hurt if I don’t have that on at night. The night guard has been scratched so badly and the crack is extending. The dentist told me that it could be last for a couple of year but it doesn’t even survive in couple of months!! I bet I will need to get another one pretty soon. I hope that my insurance will share that with me again but I kind of doubt that. I have to see if Prince Frog can play golf with me sin so I can release some of my stress. HEHE!!
