What is the part of the dental clamp that expands to fit over the tooth?

The jaw of a dental clamp is the specific part that expands to fit securely over the tooth. The jaw's design allows it to adapt to various tooth shapes and sizes, providing a stable and effective grip during dental procedures. This feature is essential for achieving proper isolation and access to the tooth while performing restorative or endodontic treatments.

The other components of the clamp play different roles. The wing refers to the extensions of the clamp that provide additional support and stability. The bar connects the wings and helps maintain the overall structure of the clamp. The clamp arm assists in the mechanism of the clamp itself but does not directly interact with the tooth in the way the jaw does. Understanding the function of each part of the clamp is crucial for effective application during dental procedures.
