Yes Ur worry cn b solved completly,but bfre that the reason fr the gap shd b found out,if u hv gap between the  two upper Frnt teeth, that will b due to the abnormal growth of the tissue band that connects the upper lip to the gums.if tht is the reason then u shd first remv that excess tissue and then go for braces treatment.or if u are having just gaps n teeth Without any reason then cn go directly from braces treatment.if u cnt wait 8-12 months fr teeth Corrctn then u cn go for smile Corrction where in a entire teeth Wil b reduced n size and a bridge of artificial cap Wil b placed,the only disadvantage is the natural teeth hav to b trimmed to.acheive tis look.
