Crowns are used to restore and enhance teeth that are damaged or fractured. A crown (also referred to as a cap) is used to entirely cover a damaged tooth. A crown not only strengthens a tooth, but it can dramatically improve a tooth’s appearance, shape and alignment.Types of crown include gold, ceramic or porcelain fused to metal, depending on the location of the crown being placed and the patient’s needs. Crowns are very durable and can last a lifetime with extra care and good oral hygiene.
Crowns may be used to:
- Replace a large filling when there is little tooth structure remaining
- Protect a weak tooth from fracturing
- Restore a fractured tooth
- Cover a dental implant
- Cover a discolored or poorly shaped tooth
- Cover a tooth that has had root canal treatment
Bridges are multiple crowns are fused together to replace a missing tooth or teeth. Different materials and types of bridges are available to replace missing teeth.
The Maryland dental bridge is one of a few types of bridges used to replace teeth. Named for the University of Maryland, where it was developed, this bridge is resin-retained and commonly used to replace the front teeth.
A pontic (false tooth) is attached to metal bands that are hidden with a white-colored composite resin and attached to the back sides of the teeth on either side of the pontic.
Conventional Fixed Bridge
With this most commonly used bridge, teeth on both sides of the missing tooth must be trimmed. A porcelain or gold crown is then placed on top of each tooth. A single false tooth (pontic) is bonded to the middle, creating a bridge between the teeth.
