It’s not too late to straighten your teeth at 24. The tissue basis for straightening teeth is due to the fact that our alveolar bone has the function of being modified by stress. That is, the alveolar bone on the side under pressure resorbs, while the alveolar bone on the opposite side experiences an increase in growth, and the teeth that are propelled in this way are shifted within the alveolar bone. Therefore, orthodontics is mainly about promoting the movement of the teeth within the jawbone through the appropriate increase in external forces, so that the teeth can be aligned and a proper bite can be formed. Generally speaking, the best time for orthodontic treatment is at the age of twelve or thirteen, after the permanent teeth have fully erupted. But that’s not to say that orthodontics can’t be done at other ages. In fact, more and more adults are now getting orthodontic treatment, and it is definitely too late to get orthodontic treatment at age 24, but it is recommended that you see an experienced orthodontist for treatment.
