Hello, you can go to Suzhou Mei Ao Dental Clinic. The best age for dental plastic surgery: in deciduous period (3-5 years old) and dentition replacement period (6- 12 years old), general tooth deformity (abnormal tooth arrangement and occlusal relationship), such as individual tooth dislocation, should not be corrected immediately. We should continue to observe and correct bad oral habits, because during this period, children's teeth are in the adjustment period, and malocclusion can often be partially corrected by themselves. And at this time, their growth and development speed is very fast, and improper correction will affect their development. However, for the malocclusion that seriously hinders the growth and development, preliminary correction is needed. Most malocclusion can't be corrected until the permanent teeth are changed, that is, 12 years old. Because the roots of permanent teeth are gradually developed and the occlusal relationship between upper and lower teeth is also adjusted, dentists can make a clear diagnosis of the types of malocclusion and take corresponding corrective measures. After the correction is completed, it is easy to maintain a stable effect and there will be no major changes.
