Misalignment of teeth bite proves that there is misalignment of teeth, the best treatment is to carry out orthodontic correction to correct the misalignment, but orthodontic treatment has an optimal age, which is 12 years old, so try to carry out orthodontic treatment when the child is small, so that the efficacy of the treatment can be guaranteed to a certain extent. If the optimal age for orthodontic treatment is missed, orthodontic treatment can also be performed, but in the later stage, a retainer needs to be worn for 2-3 years to maintain the treatment effect and prevent recurrence. The older the age for orthodontic treatment, the more difficult it is to maintain the effect of orthodontic treatment, so if you find that you have a malocclusion, it is important to correct it as early as possible, especially if the skeletal development is abnormal in childhood, and you need to start the intervention treatment around the age of 9 weeks for functional skeletal correction.
