What is the primary role of dental wedges during restorative procedures?

The primary role of dental wedges during restorative procedures is to ensure proper contact between adjacent teeth. When placing a restoration, especially in composite fillings or dental crowns, wedges are used to help maintain the integrity of the contact points between the restored tooth and its neighboring teeth. This is crucial for preventing food impaction and maintaining periodontal health, as well as ensuring that the restoration functions properly in terms of occlusion.

Wedges help to secure the matrix band, creating a well-defined contour for the restoration. This allows for the proper shaping of the filling material to mimic the natural anatomy of the tooth and achieve a tight contact with the adjacent teeth. Proper contact is vital because it helps promote healthy dental relationships and prevents issues such as decay or shifting of teeth.

The other options do not accurately define the primary role of dental wedges. For example, they are not designed for tooth extraction, preventing tooth decay or removing plaque. Their specific function is to create optimal contact during the reconstruction of a tooth, thereby ensuring long-term success of the restorative work.
