My teeth are not perfect? Help? (Photo)

I've been wearing braces for less than an year (six months or so) and the ortho decided to take them off already. They said that they we're taking it off because my roots on my front teeth were too short, thus not wanting them to fall off throughout the years as I get older. However, my teeth are still crooked and has a huge noticeable overbite. Although I did wear the bands, one of my canine is missing, restricting my jaw to be corrected from the overbite. Please help!!
