Is it possible that having an overbite puts extra gravitational stress on the upper part of the face impairing blood flow?

I got surgery for an overbite recently and I feel like my overall cognition has been improved in some way.

I've had this gravitational stress theory since upon stress my face tenses up, becomes fatigued, and I even experienced ptosis or facial paralysis during particularly bad cases. These symptoms could become alleviated though if I were to press upwards below my jaw.
