A dental bridge is an appliance used to replace one or more missing teeth. These appliances are cemented into place and cannot be removed by the patient. As the name of this appliance implies, the bridge is made out of three or more pieces that fit into the open space in the mouth, "bridging" the gap. Most bridges are made of one or more pontic teeth (or false teeth), held together by two crowns (a "cap" that covers the tooth, approximating its normal size and shape). This setup is then attached (cemented) to the abutment teeth (the surrounding teeth of each side of the gap).
Nearly everyone who has one or more missing teeth is a candidate for a dental bridge. However, the difference between proper and improper oral hygiene is generally what determines the long-term success of the dental bridge.
There are several different types of dental bridges. Your dentist or oral health specialist will recommend the most appropriate one for your mouth condition and the location of the missing tooth or teeth.
What is a typical bridge procedure?
During the first visit, the abutment teeth are prepared. Preparation involves re-contouring these teeth by removing a portion of enamel to allow room for a crown to be placed over them. Next, impressions of your teeth are made, which serve as a model from which the bridge, pontic, and crowns will be made by a dental laboratory. Your dentist will make a temporary bridge for you to wear to protect the exposed teeth and gums while your bridge is being made.
During the second visit, your temporary bridge will be removed and the new permanent bridge will be checked and adjusted, as necessary, to achieve a proper fit. Multiple visits may be required to check the fit of the metal framework and bite. This is dependent on each individual's case. If the dental bridge is a fixed (permanent) bridge, your dentist may temporarily cement it in place for a couple of weeks to make sure it is fitting properly. After a couple weeks, the bridge is permanently cemented into place.
How Long Do Dental Bridges Last?
Dental bridges can last 5 to 7 years and even longer. With good oral hygiene and regular prophylaxis, it is not unusual for the life span of a fixed bridge to be over 10 years.
How Do I Care for My Bridges?
It is important to keep your remaining teeth healthy and strong as the success of the bridge (depending on the type selected) depends on the solid foundation offered by the surrounding teeth. Brushing twice a day and flossing daily helps prevent tooth decay and gum disease that can lead to tooth loss. Your dentist or dental hygienist can demonstrate how to properly brush and floss your teeth. Keeping a regular cleaning schedule will help diagnose problems at an early stage when treatment has a better prognosis. Selecting a balanced diet for proper nutrition is also important.
What are the Alternatives to a Bridge?
Alternatives to a bridge can be a Removable Partial Denture or Dental Implants. We will discuss these options in more detail in their respective web pages.
