A denture is a removable dental appliance replacement for missing teeth and surrounding tissue. They are made to closely resemble your natural teeth and may even enhance your smile. There are two types of dentures: complete and partial dentures. Complete dentures are used when all of your teeth are missing, while partial dentures are used when some natural teeth remain. A Partial denture not only fills in the spaces created by missing teeth, it prevents other teeth from shifting. A Complete denture may be either “conventional” or “immediate”.
