A partial denture is designed to replace one or several missing teeth. Partial dentures have three different materials. A cast metal base with clasping arms holds a pink plastic gum tissue and plastic or porcelain teeth. The metal clasps are silver in colour, may or may not be visible when you talk or smile. These clasps are absolutely necessary to hold the partial in place. Their location and design are dictated by the shape and position of your remaining teeth and missing teeth to be replaced.
