3M™ Astringent Retraction Paste

Retract tissues gently.

3M™ Astringent Retraction Paste is a fast, convenient and effective solution for gingival retraction, offering an advantage over gingival retraction cords that can be difficult and time-consuming to place. The extra-fine tip delivers a 15% aluminum chloride astringent paste right into the sulcus, gently pushing the gingival tissue away from the tooth so you can efficiently capture a detailed impression of the preparation margin. It can be used for taking material-based or digital impressions for Class II and V fillings.

One cord can be replaced by 3M™ Astringent Retraction Paste, enabling temporary retraction of the marginal gingiva and providing a dry sulcus on a healthy periodontium. It can be used for taking material-based or digital impressions for Class II and V fillings.

Simple steps to a clean and dry working field.
