What is one advantage of using plastic filling materials in dental restoration?

Using plastic filling materials in dental restoration offers the advantage of requiring one fewer patient visit. This is primarily because plastic materials, such as composite resins, can often be placed directly in the cavity during a single appointment. The materials can be shaped and cured immediately, which streamlines the procedure and reduces the need for multiple visits.

This immediate application is advantageous in enhancing patient convenience and minimizing time away from normal activities or work. In contrast, other materials or methods, such as those that require impressions and time for lab fabrication of crowns or bridges, typically necessitate at least two visits, thus making them less efficient in this regard.
