You have 2 types of treatment options , 1) it can be corrected by composite restoration but after years it may wear off and you might go for re treatment , sometimes it happens and not for all the patients
2) it can be corrected by Orthodontic treatment which gives you a natural smile of yours
I would suggest you the Orthodontic treatment because your smile will be restored with your natural tooth itself and no need of any composites , it's a permanent treatment too
