No need. In general, when you shut up, your mouth is always outside and your chin is in your mouth. When you say protrusion, you should mean protrusion of maxillary incisors and lateral incisors. Usually a little. This is no problem. If it's too prominent and you think it will affect your image, you can try it. However, the orthodontic time is generally longer. 1 year to 2 years. Time is too short to grow back!
