amalgam – four or more surfaces, primary or permanent
Also referred to as a silver filling, this material is commonly utilized to fill cavities, as well as in other dental techniques. It is a combination of mercury (45-50%) and a tin, copper, and silver alloy. This ADA code refers to four or more surfaces.
amalgam – one surface, primary or permanent
Also referred to as a silver filling, this material is commonly utilized to fill cavities, as well as in other dental techniques. It is a combination of mercury (45-50%) and a tin, copper, and silver alloy. This ADA code refers to one surface.
amalgam – three surfaces, primary or permanent
Also referred to as a silver filling, this material is commonly utilized to fill cavities, as well as in other dental techniques. It is a combination of mercury (45-50%) and a tin, copper, and silver alloy. This ADA code refers to three surfaces.

anterior endodontic (or root canal) therapy – excluding final restoration
Root canal therapy, which addresses problems with the dental pulp, the soft tissue surrounding the tooth. First, the crown of the tooth is removed. The dentist then restores the soft tissue by removing damaged areas and cleaning, enlarging, and shaping the tissue to create an optimal surface that can be filled with a filler. A new crown is then placed on top. Several visits may be required for the procedure. This code indicates root canal therapy on anterior teeth, the teeth located near the front of the mouth (lower and upper incisors and canines)
apicoectomy/periradicular surgery – anterior
Surgery on the root of an anterior tooth. Placement of retrograde filling material is not included in this ADA code.
