Hello, it depends on the type of child's malocclusion. For children with deciduous teeth, it is mainly suitable for malocclusion of deciduous teeth. Early correction is beneficial to maxillary development and prevents malocclusion of permanent teeth. For children in the dentition replacement stage, if they are found to have bad habits such as biting their lips, sticking out their tongues, and protruding their jaws, as well as abnormal facial morphology and tooth arrangement, they should go to the hospital in time to check with an orthodontist to determine whether it is dental, functional or skeletal malocclusion, and make clear the treatment plan. For children in normal pressure stage, common malocclusion can be well treated at this stage.
