Crowns are "caps" that cover the entire visible portion of the affected tooth, holding it together and sealing out bacteria. Here is everything you need to know before getting a crown.
What are Dental Crowns Made From?
Crowns can be made from a variety of materials, each with their own benefits and drawbacks. Gold crowns, as well as other metal crowns, are the strongest. They don't break, even under the hardest forces, however, they are also very noticeable. Porcelain fused to metal are made to better match the color of your teeth while providing strength.
These crowns often have a visible line through them, where the metal shows through, and the porcelain can chip. Ceramic crowns are one of the most popular choices, as they can be custom made to perfectly match your teeth, but they do not offer quite the same strength as metal crowns and can crack or break.
Your Tooth Needs to Be Prepared
In order for the crown to be placed, your tooth must first be prepared. This process involves shaving down some of the enamel of your affected tooth so that the crown can comfortably and naturally fit in with the rest of your smile. A local anesthetic is used to ease any discomfort.
It Takes More than One Visit
Crowns often take two visits. During the first visit, your tooth is prepared and impressions are taken. Your dentist also uses a special guide to match the color of your natural teeth. Both the color information and the impression are sent to a lab for fabrication. While you wait, you will be provided with a temporary restoration to help protect the tooth. It can take up to two weeks for the crown to be finished. On your second visit, the crown is placed.
How Long Do Dental Crowns Last?The lifespan of your crown depends on the material from which it is made. Gold crowns, being the strongest can last upwards of 50 years or more. Porcelain and ceramic crowns can last 20 years or more. Ultimately, how you care for crowns will determine their actual lifespan.
