Buckteeth, that is, protruding teeth, are generally characterized by open lips and exposed teeth. Under natural conditions, the upper and lower lips cannot be closed, and the gums are exposed too much when smiling. Xiamen Mamaili Clay introduced that "buck teeth" can be divided into odontogenesis and osteogenesis. The odontogenic "buck teeth" is a simple tooth protrusion, which can be corrected by orthodontics. The timing of correction can be very wide, and some can even be delayed until adulthood. Of course, the earlier the correction effect, the better the psychological and life influence; Bone-derived "buck teeth" are prominent jaws, or both jaws and teeth are prominent. At this time, treatment is relatively difficult, and orthodontics and orthognathic treatment are often needed.
