Under normal circumstances, if there is a gap between teeth, it is ok to use braces for orthodontics, but it should be decided according to the situation, because the doctor has not seen the patient's condition, so it is not easy to draw a conclusion. I hope that the landlord will go to the hospital to consult an orthodontist, so that we can understand the methods and processes of orthodontics more intuitively. I hope your problem can be solved.
