Have always had a problem with this and have a custom mouth shield from the dentist which helps a lot. Unfortunately, the clenching has got a lot worse in pregnancy and sickness / (very!) strong gag reflex means I absolutely can't wear the mouth shield at the moment. I'm waking up every morning feeling poorly rested with an aching jaw and have been having headaches which I presume are related. I'm also worried about the impact on my poor teeth! Has anyone suffered similar and found anything that helps? Will contact the dentist for advice next week but desperate for any advice in the meanwhile!
