The jaws of the dental dam clamp fit around which part of the tooth?

The jaws of the dental dam clamp fit around the gingival one-third of the tooth, which is the area closest to the gum margin. This positioning is crucial because it provides stability and retention for the clamp, ensuring that the dental dam remains securely in place during a dental procedure. Clamping in this region allows for effective isolation of the working area while minimizing the potential for damage to the tooth itself. Additionally, this placement ensures that the clamp does not interfere with any restorative work or procedures being performed, as it allows access to the full clinical crown of the tooth above the gum line. Proper positioning also helps prevent any undue pressure on the sensitive gingival tissues, which can lead to discomfort for the patient.
