It seems that gums can't be corrected, only teeth can be corrected. You shouldn't say that the whole side of the teeth protrudes outward, because when I was in our school, I heard the doctor say that this kind of situation would grind the teeth a little bit and then retract them. Some teeth are too big and the gums are too small. I will pull out a tooth, but it will definitely not protrude after the final correction. You'd better consult a regular doctor
