When I developed a clenching habit, I resolved it by training myself to put my tongue in the correct position in my mouth. It is pretty simple: with your lips closed but your teeth not touching, place the tip of your tongue right where your gums and your two top front teeth meet. That's it. At first it takes effort but once the habit and muscle memory develops it'll happen naturally. This eliminated my bruxism because now my jaw has a healthy resting state.
