Hello!
I certainly understand your concerns.
There are many things which needs to be considered.
Detailed history will be helpful like impacted tooth, occlusion, snapping sonunds, stress, trigger points, head ache ect needs to be known.
Ruling out the cause and treating accordingly will be helpful, night guard alone will not help
Next Steps
Advised to visit nearby oral and maxillofacial surgeon for physical examination evaluation and treatment plan
