Narrative:

After performing maneuvers in the practice area south of new smyrna beach; I called evb tower and requested full stop landing. I was at approximately 6 miles at an altitude of 2;000 ft and they advised me to proceed to a right base for runway 07; so I flew directly to the airport and began a descent. My student was on his first training flight in a G1000 aircraft so I was preoccupied with teaching him various aspects of instrument flying and navigating at night. While I was instructing I forgot to monitor my descent to make sure I was below the class C shelf of daytona and I may have inadvertently entered daytona's class C airspace without clearance. I am not sure if I did or not because I did not think about what I had done until after the flight terminated. In the future I will certainly be more aware of my altitude and proximity to surrounding airspaces.
