If the teeth or jaws do not align this is called malocclusion, and this can lead to a number of dental problems. Many times if your bite is off it can cause more pain and destruction than the more commonly recognized problems of tooth decay or gum disease. For patients with a bite discrepancy, it is important to stabilize the jaw and bite before starting any definitive treatment on the teeth (fillings or crowns).
Ultimately, beyond a certain point does it matter? Hyenas have the bite they do because they break open bones to use for food. Other large predators have the bites they do because of the relative size of their prey. The dog has to bite hard enough to do a particular job (break a limb/hold a victim/tear a tendon or sever vertebrae on prey). Once that critical point is reached, extra is not functional.
