Too young to have veneers ?

Well I'm 15 and feel that I really need them ... Long story short ... When I was young I hit of my front teeth , and it didn't end well , it didn't grow so I ended up with one teeth longer than the other ... and it has lower my confidence when talking, smiling, etc ... So do you think I can get veneers .. maybe ones that are temporary ?!?!? Plz HELP !!!
