Bridges: A bridge replaces missing teeth by placing crowns on the teeth next to the space and attaching a fake tooth to both of the crowns. Bridges are made from gold, porcelain fused to gold, all porcelain, or zirconium. Bridges can only replace about two to three missing teeth in a row, depending on the location. Since bridges are cemented in place, they are considered a "fixed, or permanent denture."
Dentures must be handled with great care and placed in a container of water or denture cleaner when not being worn. They should never be placed in hot water, for they can be damaged or warped. They must be cleaned daily using a soft toothbrush with soap and water. The mouth should be rinsed daily without the dentures in place to clean off any plaque and reduce the risk of infection like candidiasis.
An overdenture is a removable dental prosthesis that covers and rests on one or more remaining tooth roots. A removable partial denture is a dental prosthesis that replaces some teeth and is built around existing natural teeth. Both the overdenture and the removable partial denture may be connected to the remaining tooth roots or remaining natural teeth with anchors made of metal or plastic. These connections improve stability and the retention of both prostheses.
