What is the ruling on extracting two molars and cutting a part of the gum to complete orthodontic treatment and address the protrusion of the jaw and upper teeth?

Orthodontic treatment is permissible if it is for the purpose of removing a defect or treating a deformity, provided that it is not for the sake of increasing beauty and attractiveness. If it necessitates extracting some molars or cutting a portion of the gum, and no harm results from it, then there is no objection to it.
