Yes it can and is easily done in many situations. Most adolescents need for teeth straightening requires the movement of all of their teeth. It also comes at a time of growth. It therefore takes several years to accomplish.
For adults, the growth time is obviously over and the bite is stable. When the movement of teeth is mainly the front six teeth or the “smile six” treatment is much easier and faster. It often takes just six months and can often be accomplished with invisalign. Very nice.
