This is the space that appears in a person’s top front teeth known as the upper maxillary central incisor. A good example of a famous person with Diastema is David Letterman. Some cultures regard it as sexy or sign of fertility.
Many don’t want to fix the space but, for those who do the general treatment has been in the form of braces for 12-24 months. Other quicker cosmetic corrections include bonded composites between the teeth if they are already pretty close together or with porcelain veneers if they are farther apart.
