My bite is not high after two adjustments but my tooth is very sensitive to touch/bite! To Crown or not to Crown?

This problem you're having is not uncommon. Although you might certainly have cracked tooth syndrome, which by the way, does not usually show up on an x-ray, it may be a problem with the composite filling. Occasionally the filling will pull away from the tooth leaving a microscopic gap, and when the patient bites down on it, the filling will flex (or bend) and there will be a difference in pressure in the gap which will cause discomfort to the nerve endings (more accurately "dentinal tubules"). Sometimes this settles down with time, a few weeks to a couple months.If the filling was recently done I would suggest waiting and trying to avoid biting hard on the tooth. However, if it was done a while ago, then either your dentist might replace the filling or go to the aforementioned crown restoration.

Either the tooth is cracked, OR, too much composite filling might have been placed and "cured" at once. That could result in bas stresses on remaining enamel which would cause pain. 1st step might be to remove the composite filling totally, and place a sedative temporary, and see if the discomfort subsides.
