What function does a dental matrix serve?

1. To assist with tooth extraction

2. To provide support during filling procedures

3. To enhance tooth sensitivity

4. To encourage tooth growth

The correct answer is: To provide support during filling procedures

A dental matrix serves a crucial role during filling procedures by providing support and form to the restoration being placed in the tooth cavity. During restorative treatments such as composite fillings, the matrix helps to define the shape of the filling and holds the restorative material in place until it hardens. This is particularly important for achieving the correct anatomical shape and function of the tooth, ensuring that the filling adheres properly and blends seamlessly with the contours of the surrounding teeth. By maintaining structural integrity during the process, the dental matrix contributes significantly to the overall quality and longevity of the dental restoration.
