Gingival retraction is used to temporarily push the gums away so you can see and capture the complete edge of a tooth preparation, especially when margins extend below the gum line or when multiple surfaces need a precise impression.

In pediatric patients, this full-mouth approach is warranted when margins are subgingival or when multiple surfaces require accurate impression detail. Subgingival margins are hard to reproduce without displacing tissue; a full-mouth retraction helps ensure the impression captures the true margins and the tooth’s contours, which is crucial for the fit and longevity of restorations. At the same time, pediatric tissue is more delicate and can be easily irritated, so the technique must be performed gently, with careful consideration of tissue sensitivity, minimal displacement, and appropriate materials or methods to limit trauma.

Thus, the best scenario for full-mouth gingival retraction is when margins are subgingival or when precise impression accuracy is needed across a multi-surface restoration, while always weighing tissue sensitivity and comfort for the child.
