A dental bridge is a fixed dental restoration used to replace one or more missing teeth by bridging the gap between adjacent teeth. It consists of one or more artificial teeth, known as pontics, that are anchored in place by dental crowns attached to the teeth on either side of the gap. Dental bridges are custom-made to match the color, shape, and size of the natural teeth, ensuring a seamless and natural-looking result.
There are several types of dental bridges, including:
- Traditional bridge: This is the most common type of bridge, consisting of one or more pontics suspended between two dental crowns, which are cemented onto the adjacent natural teeth.
- Cantilever bridge: In situations where there is only one adjacent tooth next to the gap, a cantilever bridge may be used. In this type of bridge, the pontic is supported by a single dental crown on one side of the gap.
- Maryland bridge (resin-bonded bridge): This type of bridge uses a metal or porcelain framework bonded to the back of the adjacent teeth with a special adhesive, eliminating the need for dental crowns. Maryland bridges are often used when the adjacent teeth are healthy and strong enough to support the bridge.
- Implant-supported bridge: Instead of being supported by adjacent natural teeth, an implant-supported bridge is anchored in place by dental implants surgically placed in the jawbone. This type of bridge is particularly suitable for replacing multiple missing teeth or when the adjacent teeth are not strong enough to support a traditional bridge.
The process of getting a dental bridge typically involves multiple dental visits. During the initial visit, the dentist will prepare the adjacent teeth by reshaping them to accommodate the dental crowns. Impressions of the teeth are then taken to fabricate the custom bridge. In the meantime, a temporary bridge may be placed to protect the exposed teeth and gums. Once the permanent bridge is ready, it is cemented or bonded into place during a subsequent visit.
Dental bridges offer several benefits, including restoring chewing and speaking function, preventing adjacent teeth from shifting out of position, and improving the appearance of the smile. However, proper oral hygiene and regular dental check-ups are essential to maintain the longevity of the bridge and overall oral health.
