Master-Dent® Vivacity™ Tooth Whitening offers sustained release of carbamide peroxide. This sticky gel has been formulated to an optimum viscosity, so that it does not escape from the tray during placement or during the whitening process. The gentle and safe formulation acts fast and effectively but avoids the high sensitivity associated with many “me-too” bleaching products. Vivacity™ has a fresh pleasant peppermint taste.
