Conventional dentures help to restore your missing teeth and gums when all of your teeth have been lost. When dentures are constructed well, they should harmoniously restore a natural appearance to your smile. You may have dentures that are severely worn and need replacement or just need an upgrade or a spare set of dentures. Some people require immediate dentures when their natural teeth are beyond salvaging. In this instance, dentures can be placed on the same day that your teeth are removed.
