Both crowns and bridges are fixed prosthetic dental devices. Unlike dentures, crowns and bridges are cemented to existing teeth or dental implants.
What is a crown & how does it work?
A crown is used to cover or cap a tooth in its entirity. Not only does this strengthen a damaged tooth, it can also be used to improve the appearance, shape and alignment. Crowns can be placed on top of an implant to provide a tooth-like shape and structure.
Your dentist may recommend a crown to:
- Replace a large filling when there isn’t enough tooth remaining
- Protect a weak tooth from fracturing
- Restore a fractured tooth
- Attach a bridge
- Cover a dental implant
- Cover a discolored or poorly shaped tooth
- Cover a tooth that has had root canal treatment
What is a bridge and how does it work?
A bridge may be used to replace the gap resulting from one or more missing teeth. Bridges span the space where teeth are missing and are cemented to natural teeth or implants surrounding the empty space. These teeth are called abutments and serve as anchors for the bridge. A replacement tooth known as a pontic is attached to the crowns that cover the abutments.
