It is not helpful to press the incisors inward as often as they protrude outward. Protruding incisors can be caused by a variety of reasons, and treatment options need to be determined on an individual basis. If the protrusion is purely dental, orthodontic treatment can be performed, which requires the removal of the weaker teeth (or distally displaced molars or lamellar teeth) and the inward retraction of the protruding front teeth through orthodontic appliances to bring them back to their correct position. If the jaw bone protrudes, the patient’s jaw bone together with the teeth protrudes forward, at this time, simple orthodontic teeth cannot achieve satisfactory results, and those with severe bony protrusion need combined orthodontic-orthognathic treatment. If the front teeth protrude forward due to bad oral habits, including mouth breathing, snoring, adenoid hypertrophy, etc., a professional doctor should be sought to remove or improve the cause of the protrusion before orthodontic treatment. Patients whose incisors protrude outward are recommended to visit the stomatology department of a hospital or a regular dental specialty hospital to clarify the specific causes and then undergo symptomatic treatment.
