A dental crown or "cap" is made to restore a tooth to its original shape and size following dental treatment like a root canal, large tooth decay, or a broken tooth. Crowns can be made out of several different materials; each with their own strengths and weaknesses.
Four Types of Crowns
1. Porcelain dental crowns--also known as Porcelain Fused to Metal or (PFM)--are one of the most popular because they can be made to closely resemble the natural look of your tooth very well.
2. Zirconia (or Bruxzir) is one of the strongest and most durable of the crowns we use, but its appearance is less translucent and may not look as natural as Porcelain.
3. Lithium Disilicate or Emax is one of the most natural-looking crowns offered and remains tough and durable as well.
4. Metal or gold crowns have a proven track record for being extremely durable and having a long life-span.
Candidates for Crowns
Damaged Teeth. Decayed, cracked, or broken teeth will need dental caps or crowns to restore the function, form, and aesthetics of the tooth.
Root Canals. A tooth that has received a root canal will need a crown to help prevent the tooth from possibly fracturing.
Large Fillings. At a high risk to break, a crown is often placed to help protect the tooth for longevity.
How the Procedure Works
The first appointment: Dr. McCabe will numb the tooth and prepare the tooth by removing old fillings and cavities and creating the ideal shape and surface for the future crown. Dr. McCabe will then take an impression of the tooth to send to the dental laboratory to hand-make a custom crown. While the lab is making the permanent crown, a temporary crown will be placed on the tooth to prevent breakage.
The following appointment: Generally two to four weeks after the first appointment, the temporary crown is removed and the new custom crown is placed on the tooth to verify a secure fit. At this time Dr. McCabe will make any needed adjustments and will cement the crown in place. After each of your visits at our Newton office, we will provide you with care instructions for your new crown. Good oral hygiene and eating habits combined with regular dental visits will help lengthen the life of your new crown.
