Teethic/fangic.

Meaning: Self-identity focused around the feeling of your teeth in your mouth (the ones affixed to your gums).

Coined specifically to describe a nonhuman/inhuman identity connected to teeth pain and sensations of burning around the mouth (with no known physical cause) and the symbolism of that (connected to inhuman hunger, intense anger/passion/drive that becomes something else, needing to hunt your feelings and ideas). But the term can be used to describe other experiences.
