Replacing a dental bridge

The main reason a bridge would have to be replaced is that a cavity forms on the tooth below.  Very few circumstances will allow a bridge to survive after a cavity is found below the bridge. 

These factors affect a bridge's lifespan:  1) a person's oral hygiene routine and diet, 2) how frequently he or she visits the dentist for a cleaning and exam, 3) what types of materials are used for the bridge, and 4) a person's occlusion/ bite.  Regarding a person's "bite", people who are heavy clenchers and grinders wear down dental restorations in their mouth much quicker.  Another reason is the quality of the dental care.  Average bridges will last 7-10 years, ususally longer if done by a quality dentist.

Unfortunately, bridges don't last forever

The most common reason a dental bridge needs to be replaced is due to recurrent decay, or a "cavity".  Sometimes that cavity goes deep underneath the bridge or below the gum tissue and can only be accessed by removing the bridge & fabricating a new bridge.   Other reasons a bridge might need to be replaced are due to mechanical failures: such as the bridge getting loose or fracturing.  Some patients have bridges that are visible in their smile and no longer look esthetically pleasing, and they replace them with a more cosmetic, non-metal option that is available today.  

The presence of a bridge does not exactly cause the problems mentioned above, just as owning a car is not the reason for car problems.  It's the type of car you buy, how you drive it, and how well you take care of it, and the natural wear and tear that affect whether or not you have car problems.
