A space between adjacent teeth is called a“diastema”.The midline diastema is a space (or gap) greater than 0.5mm between the mesial surfaces of maxillary central incisors. Midline diastema’s can be physiological dentoalveolar due to a missing tooth due to peg shaped lateral midline supernumerary teeth proclination of the upper labial segment prominent frenum and due to a self-inflicted pathology by tongue piercing.Effective diastema treatment requires correct diagnosis of its etiology and intervention relevant to the specific etiology.
