What type of material is typically used in the construction of dental wedges?

Dental wedges are typically made of wood. Wooden wedges are commonly used in restorative dentistry to help separate teeth during procedures like filling or crown placement, ensuring optimal access and visibility for the dental professional. They are designed to fit snugly between the teeth, providing the necessary separation without causing damage to the dental tissues.

Wood is favored for its ability to provide adequate traction and stability due to its rigidity while being soft enough to avoid trauma to the gingival tissue. Additionally, wooden wedges can absorb moisture, which can be beneficial during procedures.

While plastic, rubber, and metal may have different applications in dentistry, they are not standard materials used for wedges. Plastic wedges may provide some advantages in terms of flexibility, but they do not offer the same level of stability as wooden wedges. Rubber can also be used in dental applications, although the properties differ significantly, making it less suitable for creating a firm separation. Metal wedges are typically too rigid for this purpose and can cause damage to the surrounding soft tissues.
