A bridge or fixed partial denture is a restoration which replaces or spans the space where one or more teeth have been lost. There are two types of bridges - fixed and removable. Fixed bridges are bonded into place and can only be removed by a dentist. On the other hand, you can take out a removable bridge for cleaning. Removable bridges, while less expensive, may not be as desirable as fixed bridges because they are not generally stable.
Why do I need a Dental Bridge?
Your appearance, dental health, and the proper functioning of your mouth are all important reasons for wearing a bridge. A bridge helps maintain the natural shape of your face and may help support your lips and cheeks. The loss of a back tooth may cause your mouth to sink, which may make your face look older. More importantly your dental health may suffer when teeth are not replaced. Teeth were designed to complement each other. When a tooth is lost, the nearby teeth my tilt toward the empty space, or the teeth in the opposite jaw may move up or down toward the space. This places unusual stress on both the teeth and tissues in your mouth. In addition, the gum tissue and the bone that hold teeth in place can break down, increasing the risk of gum disease. Teeth that have tipped are difficult to clean, making them more likely to decay. As a result, even more teeth may be lost. Missing teeth can also affect the way you chew and speak. Chewing on only one side may cause stress to your mouth. You also need your teeth to speak properly since, in conjunction with your tongue, they make the many sounds needed in speech. If you need extensive fixed bridge work, our dentist will provide treatment or refer your to a prosthodontist. A prosthodontist is a specialist trained in restoring natural teeth and in replacing missing teeth.
How is a bridge attached?
A fixed bridge is commonly cemented to the natural teeth next to the space left by the missing tooth. A false tooth (called a pontic) replaces the lost tooth. The pontic is attached to the crowns (restorations that cover the tooth). Crowns, which are cemented onto the natural teeth, provide support for the bridge.
Types of Dental Bridges
Implants attach artificial teeth directly into the jaw or under the gum tissue. Because they require surgery, candidates for implants should have good general health and have adequate bone to place an implant. In some instances, a resin-bonded bridge, frequently called a "Maryland Bridge," can be used to replace one or more missing teeth. Because the bridge is attached by a special procedure called bonding, it doesn't require the use of crowns or extensive tooth preparation. Your dentist can determine whether this treatment method is appropriate for you.
What materials are used?
Appearance and function are considered when selecting materials for bridges. Bridges are made of gold alloys, non-precious alloys, porcelain, or combination of the materials. Porcelain is often bonded to either precious or non-precious metal. Your dentist will discuss which materials are best for you.
Maintaining your Dental Bridge
It is very important to keep your remaining teeth healthy. Brush twice a day, and clean between the teeth with floss or interdental cleaners. These measures help remove the sticky film of bacteria called plaque. Plaque causes gum disease and dental decay. A bridge can lose its support if the teeth or the bone that holds it becomes damaged by dental disease. Be especially careful to clean the areas under, around and between the bridge and your natural teeth. Dental floss threaders and special brushes can help you reach the areas. It is also important to visit your dentist regularly.
