Replacing missing front teeth can obviously improve the appearance of your smile. What most people don’t think about is what happens when a missing back tooth is not replaced. Replacing a back tooth will help you regain your normal ability to chew food and digest it properly. Each time you lose a tooth, you lose about 10% of your ability to chew. When a tooth is lost, the other teeth surrounding the space tend to move into the empty space. This contributes to an increased opportunity for decay and gum disease to begin, along with bite problems and a potential for other dental problems. Missing teeth should always be replaced—the sooner, the better.
Fixed bridges are one of the possibilities that exist for the replacement of one or more missing teeth. Other alternatives are dental implants, Maryland (bonded) bridges, partial coverage bridges, and removable partial prosthodontics.
Advantages of the fixed bridge include proven reliability and longevity. Disadvantages include cost, increased difficulty in proper cleaning by the patient, and occasionally, the necessity of preparing a tooth for an abutment (bridge support), which might not have been previously filled or even damaged.
