A diastema is an area of extra space between two or more teeth, often called a gap. The most common place for a diastema is between the front two upper teeth. Many children have diastema, especially as they lose their baby teeth and adult teeth grow in. Often, this gap will close on its own as the child gains more permanent teeth. However, some adults have diastema. If the gap causes alignment problems, or is cosmetically unappealing to a patient, there are options for closing the gap. The two most common treatments are orthodontics to move the teeth together, or veneers bonded to the outside of the tooth. Many patients keep their gap, as they feel it gives them a unique smile.
