I have a short handled denture brush that I use. I don't know if they even make them any more. You have to hold the dentures carefully while brushing. I brush them over a sink full of water, and make sure that toilet lid is down! I keep my dentures in round the clock, except to brush them. I periodically drop them in a Polident bath to make myself feel good, but they never really seem to need it. Its interesting how your body changes. Years ago I had a lot of trouble with plaque build up on my lower. I sometimes had to take a knife to it. It gradually became less as I got older, and now, in my 80's is non-existent. I have had this set of dentures for fifty years. The inside of the lowers is discolored from coffee, but other than that, they are in perfect condition. My gums shrank over time, and the lower is pretty loose. I found E-Zo pads. They are pads that you form and insert into the denture. They are only supposed to be used for two weeks if you get a canker, but I have used them for at least forty years without the slightest problem. They make my denture fit perfectly, and beat the powders and pastes by miles. Not easy to find them in the stores. I buy them on-line now.
