Who told you to collect them one by one? I'm going to faint. Orthodontic teeth are not a matter of one or two teeth at all. As long as the position of several teeth changes, the occlusal relationship will change and need to be adjusted, otherwise your temporomandibular joint will have problems. So as long as it is orthodontics in a regular hospital, especially your maxillary protrusion, it must be full of mouth. If the doctor tells you that only a few teeth have been made, and there is a charge for each tooth, it can be clearly said that the consequences are very serious.
