It is a phenomenon that is mainly affected by aesthetic problems and cannot be considered as a disease, so for patients with gummy smile, we should decide whether to treat them according to their situation. All treatments for gummy smiles are somewhat invasive. First, for very mild gummy smiles, crown lengthening can be used to remove part of the incisors’ gums and jawbone, so that the gums are relatively less exposed, but this method can damage the gums and alveolar bone. Secondly, if the gingival smile is heavy, orthodontic treatment should be used to depress the front teeth as a whole, the corresponding alveolar bone and gums will also move backward with the teeth, so that the position of the gum margin has changed, and the gingival smile will be improved, this method takes a long time, and orthodontic treatment will have a greater risk to the periodontium, and the root may become shorter. Finally, surgical treatment is also available, targeting the soft tissues of the vestibular sulcus in the upper jaw to relieve the gummy smile, but surgery is an invasive operation and carries its own risks of bleeding and infection.
