View Products

A great dental impression requires detailed margins - which starts with tissue and moisture control. 3M™ Astringent Retraction Paste provides gentle but effective gingival retraction, to help you capture a detailed impression of the preparation margin.

Gentle, Effective Gingival Retraction

3M™ Astringent Retraction Paste gently pushes the gingival tissue away from the tooth, while helping to control bleeding and improve patient comfort.

    Gentle mechanical retraction.

    The stiff material decreases the elasticity of collagen fibres and gingival tissue, compressing the gums with less trauma and irritation.

    Novel tip fits in sulcus.

    The long, slim tip provides easy access to tight interproximal areas, to help you apply the paste in – not on – the sulcus.
