GINGA-Guard protects the gingival tissue so your patients will be pain free! This light-cure resin dam material prevents damage or injury of the gingival tissue, adjacent tooth structure, or porcelain restorations that can occur during power bleaching, microabrasion or from the application of hydrofluoric acid. GINGA-Guard virtually eliminates patient sensitivity and is easy to remove due to its high flexibility and non-sticky chemistry.
