What are Dental Crowns?
A Dental crown (or cap) 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.. A crown protects and strengthens tooth structure that cannot be restored with fillings or other types of restorations.
Although there are several types of crowns, porcelain (tooth colored crown) are the most popular, because they resemble your natural teeth. They are highly durable and will last many years, but like most dental restorations, they may eventually need to be replaced. Porcelain crowns are made to match the shape, size, and color or your teeth giving you a natural, long-lasting beautiful smile.
Why are Dental Crowns Needed?
A dental crown may be needed under the following circumstances:
- Protect a weak tooth from breaking
- Hold together parts of a cracked tooth
- Restore an already broken tooth or a tooth that has been severely worn down
- Cover and support a tooth with a large filling when a lot of tooth support isn’t left
- Hold a dental bridge in place
- Cover a dental implant
- Make a cosmetic modification
What are Dental Crowns Made From?
Crowns are made from several types of materials including metal alloys, ceramics, and porcelain. When a crown is made, the material often is colored to blend in with your natural teeth.
What’s Involved In Placing A Crown?
A crown procedure usually requires two appointments.
First appointment. Your first appointment will include taking several highly accurate molds (or impressions) that will be used to create your custom crown. A mold will also be used to create a temporary crown which will stay on your tooth for approximately two weeks until your new crown is fabricated by a dental laboratory.
While the tooth is numb, the dentist will prepare the tooth by removing any decay and shaping the surface to properly fit the crown. You may get a temporary crown while you wait for the permanent crown to be ready. While you have a temporary crown, the tooth may be sensitive to hot and cold. Avoid chewing gum and eating sticky foods during this time.
Second appointment. At your second appointment, your temporary crown will be removed, the tooth will be cleaned, and your new crown will be carefully placed. You will be given care instructions and will discuss regular dental visits to monitor your new crown.
