Dentures require care that is different from natural teeth. For brushing a denture, one must keep in mind that toothpastes that are meant for real teeth contain abrasives to remove stains from the enamel surfaces.
But dentures are made from an acrylic plastic that is much softer than tooth enamel and cannot hold up to a frequent brushing with a harsh substance. It is also best to use a brush that is specifically made for dentures. The nylon bristles in a normal toothbrush can be stiff enough to cut grooves into the plastic. Over the years, I have observed dentures that aren’t even recognizable due to the meticulous scrubbing with abrasives. Another thing that can help are tablets of denture cleanser that you drop into warm water and they will effervesce plaque away from the denture. You still have to go over the denture with a gentle brushing to get the remaining deposits off. When cleaning a denture, it is usually best to do it over a sink full of water or a towel. All it takes is one slip and the denture could fall against a hard sink and crack in two. If there are any stains or deposits that do not come off with a gentle brushing, it is best to bring it to the dentist and have a professional clean them.
