What Is A Dental Crown?
A crown or “cap” is a tooth-like covering that is permanently bonded over an existing tooth or implant. Crowns help to strengthen and restore or improve the appearance of your natural teeth.
Once placed, a dental crown can only be removed by a dentist. With proper care and good oral hygiene, the life of a crown can range from 5 to 15 years.
Why Consider Dental Crowns?
A crown may be prescribed by your Dentist to:
- Restores the function of cracked or broken teeth
- Protect and support a tooth after a very large filling or root canal
- Cover a dental implant
- Look and feel like your natural teeth
- Maintains your youthful appearance
- Improve your smile by covering a misshapen or severely discolored tooth
Dental Crown Types
Your Dentist will recommend the best type of crown for your dental restoration needs based on the chewing placement and structure of the tooth or implant that requires protection. There are three types of crowns. Each type has its own characteristics and qualities:
PORCELAIN & METAL
Porcelain-fused-to-metal offers the benefits of a natural surface color that resembles the rest of your teeth and the strength of a metal substructure.
While there are several advantages to selecting this type of crown, it requires the removal of more tooth structure than other types of crowns. This means that there is greater potential for patient discomfort during the treatment procedure.
Metal offers strength and endurance. A metal crown may be recommended for back teeth where the forces of biting and chewing are the greatest. In addition, it requires minimal removal of tooth structure.
A gold or other high-noble metal crown offers biocompatibility. A base metal crown is often the least expensive treatment option; however, it lacks biocompatibility and may cause allergic reactions or gumline discoloration.
Porcelain is attractive, strong, stable, and highly resistant to wear. It offers a high level of biocompatibility because it does not contain metal.
A porcelain crown provides the best natural color match to the rest of your teeth and is an excellent choice for front teeth.
The aesthetic quality of a porcelain crown requires that the Dentist be highly skilled in the use of CEREC® CAD/CAM technology.
