Diastema refers to the presence of large gaps or spaces between two or more teeth. Diastema is most commonly seen in the upper jaw and rarely in the lower jaw. The two upper front teeth are more commonly found to be having gaps. Many children experience diastema as their primary teeth fall off. In most cases, this issue of diastema is present when the permanent teeth erupt but they resolve naturally in most cases as the child grows. When it does not resolve after 14 years of age, it calls for intervention. Certain cosmetic treatment procedures can be employed to treat diastema caused by certain reasons. Let us explore the causes and then check the cosmetic treatment available to treat them.
