Is it most relaxing for jaw for your tongue to sit between teeth with tmj?

TMJ: Try to let your tongue fall "relaxed" to the floor of your mouth between your lower teeth. Don't have your tongue pressing hard against the roof ( palate) of the mouth.

Not normal position: At postural rest normal tongue position is on floor of mouth. If you need to put tongue between teeth, it's your bodies way of telling you there is something wrong with your occlusion causing or contributing to your TMJ symptoms. See an orthodontist for occlusal evaluation. Most of the time (90%) when malocclusion corrected, TMJ symptoms diminish or disappear.

No: No. Rest position resting in floor of mouth.
