Where the teeth neighbouring a space are near pristine and one would be reluctant to hurt the perfectly good tooth structure, the tooth made to fill the space can be locked in place using thin chrome slips that glove over the healthy teeth. These types of bridge can be temporary or permanent depending on the type of glue used to fixed them in. Design will also influence how long they last. A well designed and constructed bridge should last eight years minimum and frequently 15+years if carefully looked after. To maximise a bridge’s life span a high standard of oral health care should be maintained.
