Is orthodontic treatment of gingival exposure useful?
When smiling, it is normal for the upper teeth to show 0-2mm. The reason for gum exposure may be that the upper lip is too short, which is a soft tissue problem that orthodontics cannot solve. If the reason is that the alveolar bone is too long, orthodontics can solve this problem. It is recommended to go to the hospital for an examination to see what the teeth are and then do the corresponding treatment.
