It is very important to keep your dentures clean daily to maintain good dental health. Use a soft brush and a cleaning agent, such as soap and water or a denture product recommended by your dentist. Brush both sides, inside and out to make sure you are eliminating any bacteria. You may also soak your denture in water when you take them out at night. Your dentist can explain the best way to care for your dentures, if you have any questions.
