Quizplus · Accepted Answer

Option A is correct as a wedge is placed to apply pressure to the apical and gingival walls of the preparation and reduce the risk of moisture contamination and flaring of the tooth during the filling process. 
Option B is also true as the wedge pushes against the band (used in interproximal cavities) and causes the teeth to separate slightly, making the restoration process easier. 
Option C is incorrect as there are other commonly used types of wedges like wooden wedges, anatomical wedges, and matrix wedges.
