Before the dentist is seen--does the bottom front teeth touch the inside of the upper top teeth for a proper bite or only the back teeth should touch?

Ideally: Ideally, all teeth should touch and equally when the mouth is closed.

Occlusion: You've described an occlusion with a slight overbite and overjet. All teeth should meet harmoniously when you bite down.

A proper bite : In dentistry your bite basically refers to how your teeth come together. When teeth bite together in the “normal” bite, all of the teeth front teeth and back teeth should contact.
