Gingival retraction solution

A gingival retraction solution is a liquid dental agent applied to temporarily move gum tissue away from a tooth during procedures such as crown preparation or impression taking. It works by causing the superficial layers of the free gingiva to contract, improving visibility and access while helping control minor bleeding and fluid seepage.

These solutions are designed for single use and are not reused after application. They are regulated as medical devices based on their mechanism of action—typically relying on physical or chemical effects like astringency rather than pharmacological activity—and are supplied as sterile or non-sterile liquids for direct application to retraction cord or tissue.
