Which dental accessory is used to create separation between teeth during a restoration?

• A. Matrix Retainer
• B. Dental Dam Clamp
• C. Articulating Paper
• D. Wedge

Answer: (D)

Creating space between adjacent teeth is essential to properly seat the matrix band and form a good proximal contact during a restoration. The wedge is placed between teeth to gently push the neighboring tooth away, creating a small, triangular gap behind the matrix band. This separation allows the matrix to seal tightly against the tooth and provides room for the restorative material to be shaped so the contact is accurate and there’s no excess material at the gingival margin. It also helps prevent flash and matrix distortion during placement. The matrix retainer holds the matrix band in place, the dental dam clamp isolates the area with a rubber dam, and articulating paper is used to check occlusion after finishing. Hence, the wedge is the accessory used to create separation between teeth during a restoration.
