Ensure your dentures say in throughout the day with the great tasting Effergrip Denture Adhesive Cream. Simply apply three short strips in the middle of the denture and then firmly place and hold for 20 seconds to lock in place. Unlike some denture adhesives, Effergrip Denture Adhesive does not contain zinc. High concentrations of zinc have been shown to have health risks. What Effergrip Denture Adhesive does have is an extra strong adhesive for a powerful grip. You'll feel confident your dentures won't slip even when eating something that requires a lot of pressure.
