? On this question, many adults with irregular teeth or adults who missed the best opportunity of orthodontics in childhood will want to know the answer.

Experts from Kang Jie Stomatological Hospital pointed out that because the growth and development of adults have stopped, bone metabolism and alveolar bone remodeling are relatively slow, and the speed of tooth movement is relatively slow, orthodontics takes longer than that of children. However, due to the high cooperation of adults and some characteristics of adults, the effect of adult orthodontics sometimes even exceeds that of children. In principle, as long as the periodontal health, adults can also carry out orthodontic treatment. However, due to the particularity of adults' physical condition, orthodontic design has strict principles, such as small-scale tooth movement, consideration of the relationship between posterior teeth and jaw, evaluation and balance of aesthetics and function, etc., which are different from childhood treatment.
