It is important to treat your dentures like you would treat your natural teeth. They should be kept as clean as possible to prevent further tooth loss, inflamed gums, or bacterial and fungal infections. We usually recommend that you clean them thoroughly twice a day, and after eating when necessary.
The general rule is: brush, soak, brush. Always clean your dentures over a bowl of water or a folded towel in case you drop them. Brush your dentures before soaking, to help remove any food debris. Using an effervescent (fizzy) denture cleaner will help remove stubborn stains and leave your denture feeling fresher. Always follow the manufacturer's instructions. Then brush the dentures again, as you would your own teeth, being careful not to scrub too hard as this may cause grooves in the surface. Most dentists advise using toothpaste and a small to medium-headed toothbrush. Make sure you clean all the surfaces of the dentures, including the surface which touches your gums. This is especially important if you use any kind of denture fixative.
It is important to visit your dentist regularly even if you don't have any of your natural teeth. Dentists do not only check teeth, but also the soft parts of the mouth, including the tongue and cheeks. These examinations are just as important, so the dentist can spot any infections, mouth conditions or even mouth cancer at the earliest stages. Your dentist will be able to tell you how often you should visit.
