A dental crown is a tooth-shaped “cap” that is placed over a tooth — to cover the tooth to restore its shape and size, strength, and improve its appearance.
The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.
Why Is a Dental Crown Needed?
A dental crown may be needed in the following situations:
- To protect a weak tooth (for instance, from decay) from breaking or to hold together parts of a cracked tooth
- To restore an already broken tooth or a tooth that has been severely worn down
- To cover and support a tooth with a large filling when there isn’t a lot of tooth left
- To hold a dental bridge in place
- To cover misshapened or severely discolored teeth
- To cover a dental implant
- To make a cosmetic modification
Dental bridges literally bridge the gap created by one or more missing teeth.
A bridge is made up of two or more crowns for the teeth on either side of the gap — these two or more 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 natural teeth or implants.
What Are the Benefits of Dental Bridges?
Bridges can:
- Restore your smile
- Restore the 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
