What Are Dental Crowns?
A dental crown is a tooth-shaped "cap" that is placed over a tooth to restore its shape, size, strength, and appearance. When cemented into place, crowns fully cover the entire visible portion of the tooth above the gum line.
Crowns may be needed to protect a weak tooth from breaking, hold together parts of a cracked tooth, restore a tooth that is already broken or severely worn down, or cover and support a tooth with a large filling when there is not much natural tooth structure remaining.
Types of Crowns
Crowns can be made from several different materials, each with its own advantages:
- Porcelain or ceramic - Best for matching the natural color of your teeth, ideal for front teeth
- Porcelain fused to metal - Combines strength with a natural appearance
- Gold alloys - Highly durable and gentle on opposing teeth
- Base metal alloys - Very strong and resistant to corrosion
What Are Dental Bridges?
A dental bridge literally "bridges" 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 (called abutment teeth) and a false tooth or teeth in between (called pontics).
Bridges can restore your smile, maintain the shape of your face, distribute the forces in your bite properly, and prevent remaining teeth from drifting out of position.
The Crown & Bridge Process
First Visit - Preparation
Your dentist reshapes the tooth to allow room for the crown, takes impressions, and places a temporary crown to protect the prepared tooth while your permanent crown is being made.
Second Visit - Placement
The temporary crown is removed and the new permanent crown is checked for fit and color match. Once everything looks right, it is cemented permanently into place.
When a Crown Comes Loose
Sometimes crowns or bridges can become loose or fall off. This is often due to decay underneath the crown, improper fit, or the cement washing out over time. If your crown comes loose, contact our office right away. In many cases, we can re-cement the crown the same day.
While waiting for your appointment, you can temporarily slip the crown back over the tooth using dental adhesive or denture cream. Do not use household glue.
Caring for Your Crown or Bridge
With proper care, a good quality crown or bridge can last many years. Practice good oral hygiene by brushing twice a day and flossing daily. Use a floss threader to clean under and around your bridge. See your dentist regularly for checkups and professional cleanings.
