hi there
just looked at previous thread. I started tooth grininding when doing teacher training few years back. i was completely unaware of it- but very aware of terrible headaches all over my head, thought they were stress induced. eventually a sensible dentist sent me to the dental hospital who agreed with first dentist- made a guard and as long as i wear it if i feel stressed its fine (ive literally chewed through 4 of them).
dentist said if i was ever aware of doing it in day to put my tongue resting between top and bottom teeth so i couldnt grind.
its v odd with the headaches beacuse they dont feel related to the jaw- but generally they dont occur with the guard so must be it.
other advice was- no chewing gum, no chewing pens, no toffees etc.
Good luck!
