Gly-Oxide Antiseptic Oral Cleanser uses a carbamide peroxide formula to provide oxygenating action that cleanses hard-to-reach areas and aids in the treatment of minor oral irritation. It releases oxygen on contact with oral tissue to help heal canker sores, denture irritation, and post-dental-procedure soreness. The concentrated formula means only a small amount is needed per use, making each bottle last a long time.
