What is an overhanging restoration?

  1. A filling that is below the tooth surface

  2. Filling material extending past the tooth preparation

  3. A filling that fits perfectly into the tooth

  4. A type of dental adhesive

The correct answer is: Filling material extending past the tooth preparation

An overhanging restoration refers to filling material that extends beyond the edges of the tooth preparation, which is the area that has been shaped or excavated to receive the filling. This situation can occur when the restorative material is improperly placed or when the original cavity preparation is not adequately shaped to accommodate the filling material. Overhanging restorations can lead to various dental issues, such as plaque accumulation, which may increase the risk of secondary caries, periodontal disease, and discomfort for the patient. In contrast, options describing fillings that fit perfectly into the tooth, fillings that are below the tooth surface, or types of adhesives do not accurately capture the definition and implications of an overhanging restoration.
