30-year-old teeth can be corrected. As long as the deciduous teeth are replaced, they can be corrected at any age. There is only one optimal age for orthodontics, that is, after the dentition period, the optimal age for orthodontics is when all permanent teeth erupt, and adolescents 12- 14 years old have the best orthodontic effect.
