Since dentures can not be whitened, take care to minimize the chances of staining by cleaning your dentures every day with a soft toothbrush and non-abrasive soap or denture paste. Do not use normal toothpaste, because it often contains materials that can damage the plastic. After cleaning your dentures properly, soak them in water-based cleaning solution each night. If you damage your dentures, make an appointment to come in and see us immediately. Do not attempt to fix them on their own. They may require a simple reline that only professionals have the means to perform. They may no longer fit properly because your jaw has changed shape.
