Space Closure

  • Space Closure(Diastema)

Diastema is a gap or space between two teeth. The term is most commonly applied to be an open space between the upper incisors (front teeth). It happens when there is an unequal relationship between the size of the teeth and the jaw. Many species of mammals have diastema as a normal feature, for example the gap between molars and incisors in rodents.
Diastema is sometimes caused or exacerbated by the action of a labial frenulum (the tissue around the lip) causing high mucosal attachment and less attached keratinized tissue which is more prone to recession or by tongue thrusting, which can push the teeth apart.
In the Canterbury Tales, Geoffrey Chaucer wrote of the "gap-toothed wife of Bath." As early as this time period, the gap between the front teeth, especially in women, had been associated with lustful characteristics. Thus, the implication in describing "the gap-toothed wife of Bath" is that she is a middle-aged woman with insatiable lust. This has no scientific basis, but it has been a popular assumption in folklore since the Middle Ages.
In Nigerian society, diastemata are occasionally regarded as being attractive mostly among the western regions, and some people have even had them created through cosmetic dentistry. In France, they are called "dents du bonheur" ("lucky teeth").
