Does overbite always mean recession ?

[Constantin Denis]

My upper teeth cover my lower teeth by about 40% of the lower teeth ? that normal ?

It might be normal by what I found on google.

"So how, optimally, should our teeth align? FROM THE FRONT: your upper front teeth should fall in front of your lower teeth (toward your lip), and should overlap them by about 2 mm. Upper and lower front teeth should hit lightly."
