What is a partial denture?
This is a plate with one or more false teeth on it. It may be all plastic or a mixture of metal and plastic. Both types may have clips (clasps) to help keep the denture in place in your mouth. Depending on where they are, some of these clips may show when you smile or open your mouth.
What is the difference between a plastic partial denture and one that contains metal?
Plastic partial dentures are less expensive to make. But unless they are designed very carefully they can damage the teeth they fit against.
Metal partial dentures are usually made from an alloy of cobalt and chromium, and they are much stronger. They are lighter to wear and can be supported by the remaining teeth. Although the base is metal, they have gum-coloured plastic and natural-looking teeth fixed to them. They are more expensive than plastic ones.
What is the alternative to a partial denture?
The main alternatives are a fixed bridge or a dental implant. A dental bridge is made by putting crowns on the teeth at either side of the gap, and then joining these two crowns together by placing a false tooth in the space. This is all made in the laboratory and then the pieces are cemented into place with special adhesives. The bridge can’t be removed.
Another option is an adhesive bridge. This has ‘wings’ that are bonded to the back of the supporting teeth, with very little drilling needed.
