A diastema is a space between front teeth. Diastemas are closed by orthodontics or restoration. A highly successful technique is addition of composite. A space which is too large and closed with composite results in teeth that are esthetically too wide and orthodontics is recommended. Space closure requires placement of composite two adjacent teeth. Placement of composite onto one tooth can be done it proper tooth dimensions allow it. Anesthetic is not required unless dentin or root structure is involved. Diamond burs prepare tooth structure creating a rough surface for improved bond strength and to produce bevels that show through tooth color at restoration cavosurface areas. Cross section of enamel rods improves enamel bond strength
