I have an old habit of gently resting the tip on the roof of the mouth at the front, where the palate transitions from hard to soft, because it limits saliva production. Anyway, I use this as an anchor to remind me to let the muscles of the head 'sag' off the gentle post of the spine.
This can also keep the shoulders down, but watch that you keep the lumbar spine curved - thinking about sagging can sometimes lead to slouch, which is swinging too far the other way, from tension to flop.
Thank you for your comments. Perhaps I should've mentioned that I usually use a reclining restorative yoga pose for meditation, so my head is actually resting on a blanket, with a rolled portion to support the neck. Perhaps it is the posture itself that is promoting the tension. I do always let the jaw hang very slack and have experimented with various tongue positions. It seems that focusing on breath sensations further down in the body, such as the abdomen, leads to less tension in the face than focusing higher in the body - at the nostrils, say. This issue with face tension does not arise with walking or sitting mediation, but I use those rarely.
