I've been told my my orthodontist that i need 2 years of braces and 1 year retainer

He said that he needs to fix my bite. He also said that that's gonna be the reason I have to have them on so long, and personally I don't think I have a bad overnight he said its a slight overbite. So I was wondering if I should get jaw correctional surgery or if I should just get braces for 2 years and honestly I don't really want braces. So is there any way he could fix my teeth and not my bite ?
