A dental crown is an appliance, sometimes called a “cap”, that is placed to restore or replace the top of your natural tooth. When healthy, a tooth root is encased in gum tissue and bone, and the natural crown extends above the gum line. If a tooth needs replacement, or if tooth damage needs to be fixed, your dentist may place a dental crown on top of the existing root or an implant.
Dental Crowns are used in many circumstances:
- To restore a damaged tooth or replace a large filling
- To hold a dental bridge in place
- To cap a dental implant
- To protect a weak tooth or stop a damaged tooth from fracturing
- To cover a tooth after a root canal
- Crowns can save teeth with very large cavities. If a tooth has been badly damaged by tooth decay a crown can be used to save a tooth from undergoing a root canal procedure.
- Crowns can “cap” tooth restored by a root canal. After a root canal is completed a crown can be placed over the root canal to return the tooth to its function.
- Crowns can hold together severely cracked or even broken teeth and save them from extraction. Basically, a crown “restores” a damaged tooth to its original look and function.
- Crowns can protect a worn tooth or cover a misshapen one. Crowns can restore a tooth to its original strength and function, and even save it from having to be extracted.
- Crowns can anchor dental bridges. If crowns are placed on teeth adjacent to a missing tooth, they can hold a permanent dental bridge in place.
- Crowns really last! Crowns typically last from five to ten years and some last even longer.
- Crowns stay in place! Because crowns are fixed to your teeth, they do not move, slide, or drop out. Once you have a crown? It stays put!
DENTAL CROWNS STUDY:
“The up to 25-Year Survival and Clinical Performance of 2,340 High Gold-Based Metal-Ceramic Single Crowns”
This study tracked the success rate of 2,340 crowns installed by one specialist.
It showed that at 10 years, the success rate was 97% (2,270 crowns that lasted over a decade).
At 25 years, the success rate was 85%.
That’s 1,989 out of 2,340 crowns that lasted over 25 years.
