Dental bridges literally bridge the gap created by one or more missing teeth.
A bridge is made up of two crowns one on each tooth on either side of the gap — these two anchoring teeth are called abutment teeth — and a false tooth/teeth in between. These false teeth are called pontics and can be made from gold, alloys, porcelain or a combination of these materials. Dental bridges are supported by
either natural teeth or dental implants.
What Are the Benefits of Dental Bridges?
Bridges:
- Restore your smile
- Restore your ability to properly chew and speak
- Maintain the shape of your face
- Distribute the forces in your bite properly by replacing missing teeth
- Prevent remaining teeth from drifting out of position
What Types of Dental Bridges Are Available?
There are three main types of bridges:
- Traditional bridges involve creating a crown for the tooth or implant on either side of the missing tooth, with a pontic in between. Traditional bridges are the most common type of bridge and are made of either porcelain fused to metal or ceramics.
- Cantilever bridges are used when there are adjacent teeth on only one side of the missing tooth or teeth.
Cantilever bridges are usually used to replace only one tooth. - Maryland bonded bridges (also called a resin-bonded bridge or a Maryland bridge) are made of plastic teeth and gums supported by a metal framework. Metal wings on each side of the bridge are bonded to your existing teeth.

What Is the Process for Obtaining a Dental Bridge?
During the first visit, the abutment teeth are prepared for the crown. Preparation involves recontouring 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.
Dental Implants
What are the different types of dental implants?
Historically, there have been two different types of dental implants: (1) endosteal and (2) subperiosteal. Endosteal refers to an implant that is “in the bone,” and subperiosteal refers to an implant that rests on top of the jawbone under the gum tissue. Subperiosteal implants are no longer in use today because of their poor long-term results in comparison to endosteal dental implants.

How Much Do Dental Bridges Cost?
The cost of dental bridges varies depending on the type of bridge selected and the area of the country in which the procedure is performed. Dental insurance will typically pay a percentage of the fee depending on the individual dental plan.
How Long Do Dental Bridges Last?
Dental bridges can last 5 to 15 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.
Will It Be Difficult to Eat with a Dental Bridge?
Replacing missing teeth should actually make eating easier. Until you become accustomed to the bridge, eat soft foods that have been cut into small pieces.
Will the Dental Bridge Change How I Speak?
It can be difficult to speak clearly when teeth are missing in the front or anterior areas. Wearing a dental bridge with the anterior teeth in their proper relationship will help you speak properly.
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.
