I need advice and help with jaw tension please?

Hiya all!

I’ve had a look at some other threads on teeth grinding and what not but my problem is slightly different and I wanted to get a new lot of opinions on this if possible.

About two years ago I started getting sensitive teeth not with hot and cold things but with sweet things. Anyway, I went to Dentist and he said that I must be clenching or grinding my teeth at night. I did then notice that during the day I was tensing my jaw and clenching my teeth.

The problem has gradually got worse and worse and I keep becoming aware that i have tension in my jaw and teeth, sometimes holding my teeth together and sometimes not. I’m now getting really bad headaches and am not sleeping very well.

I went to the dentist this morning and she has prescribed me a night-guard. Will this stop the headaches though? and How do I stop doing it during the day if I’m not aware of it? What cause jaw tension??? Is it just stress? Do I need to chill out!? If so…any ideas that have worked for you?
