Fittydent Tablet 4's removes residue and keeps orthodontic and denture equipment ready for use. Its key ingredient, sodium perborate monohydrate, cleans away all non-water-soluble residues and keeps the gadgets extra-smooth and clear. Active oxygen is present in sodium perborate monohydrate, which is also used as a bleaching agent. In contact with water, sodium perborate monohydrate hydrolyzes into hydrogen and borate, leaving a smooth, clean surface. Fittydent Tablet should only be used as directed by your dentist. Do not swallow these tablets. Take off your dentures and use a toothbrush and running water to clean them. Put a pill into some warm water. Use just ice-cold water. Denture or brace should be soaked in the remedy for at least 10 - 15 minutes.Disclaimer:For more information contact your physician.
