The problems that arise depend on the way you choose. If you choose to do surgical osteotomy, you will naturally have swelling and pain, but you can heal yourself.
If you choose orthodontics, because it is a gradual way, there should be basically no discomfort after surgery, and you should feel relaxed.
If you choose porcelain crown or porcelain veneer to beautify the front teeth, you may feel tight and slightly foreign body feeling that day.
