How can i tell the difference between dental or skeletal overbite?

Have "buck" teeth?: If your teeth are lined up over the arch or ridge of bone yet there is a distance from the front of your lower teeth to the back of your upper teeth you have a skeletal problem. If the upper and lower teeth touch but crowding or periodontal disease have push the upper teeth out you have a dental problem. Many times a side view skeletal xray is necessary to tell the difference.
