It sounds like you may have some temperomandibular joint disorders, and it is best to get it checked by a dentist.
Jaws are meant to open straight down (like a door hinge) and not diagonally, unless you have jaws that are not symmetrical.
The clicking sound may be from your jaw joints, and some people do experience this at certain stages in their life.
If your jawbone is not symmetrical and you have crooked teeth, then you will need to see an orthodontist. Hope this helps. Good luck!
