What Is a Dental Bridge?
Dental Bridge
A dental bridge works by eliminating a gap between one or more missing teeth. A bridge consists of two or more crowns that are placed on the teeth on both sides of the gap. These are called the abutment teeth and act as an anchor for the bridge. Pontics or prosthetic teeth are placed between the crowns. In many cases, these teeth are typically made from alloys, porcelain, or gold. While the natural teeth typically support a dental bridge, a dental implant can also anchor the bridge.
Benefits
There are multiple benefits of dental bridges which are summarized below:
- Ability to speak clearly
- Chew correctly without issue
- Evenly distribute forces from chewing and biting down
- Facial shape and structure are preserved
- Natural teeth are protected
- Smile is restored
Types
There are three different types of dental bridges which are used. This includes traditional, Maryland, and cantilever bridges which are summarized in more detail below.
Traditional bridges use a crown on both sides of the missing tooth or teeth. The pontic or prosthetic tooth is then placed in the middle of the crowns. These bridges are most commonly used and are typically created from porcelain which is fused to a metal or ceramic material.
A Maryland bridge is a bridge created from porcelain, porcelain fused to metal, or plastic teeth and gums which are supported by a porcelain or metal framework. A “wing”, created with metal or porcelain, is then bonded to the existing teeth on both sides of the bridge.
A cantilever bridge is used in cases where just one tooth is next to the missing tooth. This type of bridge is rarely used because it lacks support and it is not recommended to replace missing teeth in the back of the mouth. One challenge with a cantilever bridge is that too much force is placed on the existing teeth which often causes damage.
Procedure
The initial visit for obtaining a dental bridge involves preparation of the abutment teeth. Some of the enamel is removed from the teeth to accommodate and place the crown. Impressions of the teeth are then obtained. The impressions are used as a model for the creation of the pontic and crowns used in the bridge. A dental lab typically creates the components of a crown. A temporary bridge is often placed to protect the teeth and gums while a permanent bridge is being created.
During the second stage of the procedure, the temporary bridge is removed. The dental professional will adjust the new bridge as needed to ensure it fits properly. In order to ensure the bridge fits perfectly, patients often need to make multiple visits to the office. In the event the dentist is installing a fixed dental bridge, a temporary cement is often used to ensure proper fit is achieved. Once the dentist and patient are satisfied with the bridge, it will be permanently cemented into place.
Cost
The cost for a dental bridge will vary based on numerous factors such as the dentist, type of bridge, additional procedures, and the geographical location. In many cases, dental insurance will cover at least a portion of the procedure. Patients who practice good oral hygiene and properly care for their bridge can expect them to last for 15 years or more.
