Dentures, also known as false teeth, are used to mask missing teeth. All of your teeth are replaced with a full set. A part collection is a set of teeth that is used to replace one or more missing teeth. Dentures are made to match your mouth by taking impressions (mouldings) of your gums. Usually, they’re made of metal or plastic. They’re removable so you can clean them, though part dentures can be cleaned when you’re brushing your teeth. It is enough to remove the entire set and soak it in a cleaning solution. If you lose your natural teeth, dentures are required because losing your teeth makes it difficult to chew your food, affecting your diet and potentially causing facial muscle sagging.
