What can my orthodontist do about my tooth high up and lower canines? (Photo)

One tooth next to my front tooth has grown in higher than the other teeth. I've had braces for 2 years and nothing has seemed to change. Should my ortho have me cut the gum and put the bracket up higher. Also I had a tooth that was loose but would not come out, finally it did but the new tooth had already began to grow in and was crooked and below the gum line. My ortho says they're coming in but she won't pull brackets on them because it's below the gum line. Can't I just cut the gum?
