An artificial tooth is bonded to a malformed tooth without cutting the tooth, whereby a row of teeth is changed in a rapid and straightforward manner. The muscles surrounding the mouth cavity are pushed by the artificial tooth, thereby changing the appearance of the face. The present invention provides a bonding tooth ( 1 ) that is bonded to a tooth (T) in a row of malformed teeth so that muscles of the mouth in front of the maxillary and mandibular bodies, which muscles constitute most of the mouth muscles that control the appearance of the mouth, are subjected to pressure from an interior of the mouth cavity, and the appearance of the mouth is caused to change. The bonding tooth comprises a bonding tooth surface part ( 3 ) of a coloration similar to that of the tooth (T), a bonding tooth main body ( 2 ) of such a thickness that the mouth muscles are subjected to pressure and an optimal row of teeth are obtained, and a bonding surface ( 4 ) formed on a rear surface of the bonding tooth main body ( 2 ) and provided with a profiling surface so as to come into engagement with in the shape of an obverse surface of the tooth (T).
