The important question is whether this gap always existed or whether this is a recent development. If this always was the case then you need not do anything about it unless you are concerned with esthetics. All you will need to take care is to keep good oral hygiene . However if this is a recent development then you may have gum disease in which case you need to seek help. Get a proper opinion after examination.
