If a person wants to have neat, beautiful, and fully functional teeth, they must undergo regular check ups; Discovering abnormal issues with gum development or tooth arrangement should be evaluated by an orthodontist to determine the optimal treatment timing.

        For example, general Dental malformation， The more suitable time for orthodontic treatment is around 12 years old (all deciduous teeth before * * permanent molars have been replaced), but some people have their teeth replaced earlier, and all deciduous teeth may fall out around 10 years old. Some people's rapid growth during puberty lags behind, and there may still be residual deciduous teeth at the age of 14 or 15. Therefore, the timing of treatment for these two types of patients will differ by three to four years.

        Looking at the developmental characteristics of a person's teeth, jaw, and face, the "reverse bite" deformity of the front teeth in childhood is commonly known as "Dibao Tian”， If detected early, a * * simple Orthodontic appliance It can take effect within one or two months; After the 6-year-old tooth replacement period, the growth of the lower third of the face is slightly later than that of the upper part of the face. Therefore, for yellow skinned people who are prone to mandibular hypoplasia and deformities, special "orthodontic" measures - functional orthodontics (usually implemented around 8-10 years old) can correct some facial deformities. If left untreated after the age of 12, the effectiveness of facial orthodontics will be greatly reduced.

　　 For many adults who have missed the best opportunity but want to improve their facial appearance or oral function through orthodontic treatment, their teeth can move under external traction in the dental arch for life. Wang Ying said that as long as they choose a regular orthodontist, reasonable orthodontic goals can be achieved.

　　 In addition, another extreme case is severe facial and dental deformities caused by genetics, such as a "giant chin" or a small jawline resembling a bird's beak. Orthodontics alone cannot solve the fundamental problem, and these patients can only wait until adulthood to undergo facial plastic surgery.
