Orthodontic braces are commonly used in childhood or adolescence to correct and align teeth, but many patients experience their teeth becoming crooked again shortly after treatment ends, leaving them frustrated. According to Alexander Cassandri Nishida, a dental surgeon and orthodontist, this phenomenon is not uncommon and can be attributed to the natural remodeling of teeth that occurs over a person's lifetime. Factors such as growth during adolescence, aging, teeth grinding, or changes in the bone can affect the positioning of teeth even after orthodontic treatment has concluded.

Nishida explains that a young person who finishes orthodontic treatment at 16 may still see slight movements in their teeth until their growth completes, along with subtle shifts in adulthood. This is because teeth do not remain permanently fixed to the bone; rather, their roots are embedded in surrounding bone, allowing for potential movement caused by various life circumstances. Consequently, individuals who have undergone orthodontic treatment might need to consider additional measures to maintain alignment as they grow older.

The implications of these findings suggest that ongoing dental care and possibly additional treatments, such as retainers or follow-up orthodontic work, could be crucial in preventing teeth from reverting back to their original positions. Understanding the dynamic nature of dental health can help set realistic expectations for patients undergoing orthodontic treatment and emphasize the importance of maintaining dental habits beyond the active treatment phase.
