What should I do if orthodontics fails?

Saving narrative should be possible, but it is more difficult. Because there are gaps between teeth, if there are no gaps, it is really difficult for teeth to protrude or be crowded.

Moreover, absolute age is not the most important. Orthodontics can be done at any age as long as the periodontal health is adequate. There are 60-and 70-year-old orthodontic patients at home and abroad. Technology is not a problem, but elderly patients are unwilling to accept it, so don't worry about age.
