Teeth are uneven, see when they appear. If the maxillary central incisor has just erupted and there is a gap in the middle, it is called temporary malocclusion. You can wait for the lateral incisors to erupt, push the two central incisors to move to the midline, and close the space between the central incisors without special treatment. If the newly erupted permanent teeth are unevenly arranged, occlusion induction can be carried out, that is, some appliances can be worn, and Roma appliances are commonly used. Promote jaw development, so that teeth are naturally arranged in the correct dental arch position. If you are 12 years old, most of the teeth have erupted and the teeth are not aligned, then you can go to the stomatology department of a regular hospital or the orthodontics department of a big hospital. Wearing orthodontic appliances regularly to correct tooth dislocation can also promote the development of jaw, make the underdeveloped jaw develop and inhibit the overgrowth of jaw. If you grow up, that is, after 18 years old, there are still teeth that are not aligned properly, which can only be corrected by orthodontics.
