My son's lateral incisor tooth tilted horizontal (not sure whether it is by hurt or genetic) blocking the front incisor teeth.We took X-ray and visited doctors for taking different opinions. Some of them say wait and watch till 11-12 years of age(His current age is 7 years) and some say, go for surgery where they will keep clip/brace to move the blocked tooth and pull the incisor above it. I can attach the X-ray report as well.

Is it correct to go for the surgery or wait till 11 years and decide then ?
Please suggest and help.
