Plaque is a sticky film that forms on your teeth. Plaque is formed when the bacteria in your mouth mingles with the sugars and starches from your food. Since plaque re-forms quickly, it requires daily removal with a good dental hygiene routine.2 Plaque can build-up on your dentures the same way that it can build up on your teeth, staining and discoloring your dentures or leaving them with a funky odor. If left untreated, plaque can harden into tartar, which will make your dentures feel uncomfortable and look dirty. If you find that you’ve developed tartar on your dentures, your dental team can remove it with an efficient cleaning machine.3
