Should a full crown cover the entire dentin/cementum of the old tooth once a dentist shaves it down,

The tooth never had floss hurt it or had pain when water or air touched it.

This is a side view..
In the back inner corner of the crown there is also a gap where food gets stuck,
When I floss the back between the crown and the gum of my jaw food is always there between the crown and my gum line ..
This never happened with the original tooth ...and by the liquid and air pain it makes me think nerves are exposed.

Why was a crown recommended in the first place and not only a normal filling? You do sometimes see the dentin margin when placing a crown.Complete full coverage of the entire tooth, is usually done in more aesthetic areas. In the back, it is up to the clinician to determine where the tooth preparation should end. To evaluate the proper fit, I would need to see an x-ray to determine if there is a gap
