When placing separators with floss, what motion should be used?

When placing separators with floss, utilizing a see-saw motion is the most effective technique. This method allows for the gentle insertion and adjustment of the separator between the teeth without causing excessive trauma to the gums or the adjacent tooth structures.

The see-saw motion helps to create space gradually, ensuring that the separator is properly positioned. By moving the floss in a back-and-forth manner, dental professionals can more easily maneuver the separator into place, accommodating the contours of the teeth and minimizing discomfort for the patient.

In contrast, other motions such as a twist motion might not provide the necessary control and could potentially displace the separator or damage the tooth or gingival tissue. A straight pull motion could also lead to difficulties in managing the separator's position effectively. The push-pull motion may similarly lack the finesse needed to place the separator accurately. Hence, the see-saw motion is the preferred approach for this procedure.
