Why have implants made bridges less commonly recommended?
Implants have a very distinct advantage of being easier to clean since you can floss between all teeth still. A bridge requires you to thread floss under the fake tooth, which some people find difficult. Another significant advantage is that you do not need to crown the adjacent teeth. When a bridge fails it is at minimum a 3 tooth problem. Sometimes when the bridge fails one of the teeth supporting it must be pulled. An implant and two adjacent teeth keeps your teeth (and potential problems) separate.
