A crown is a cap for a damaged tooth. It is needed when a tooth has a large amount of decay (cavities), fracture lines, root canal treatment, or decay around an existing crown.
You might need a crown if you have a cavity that’s too big for a filling. Crowns replace large areas of missing tooth material, and hold together a tooth that shows signs of breaking (due to fractures or symptoms). They are a great way to restore the shape of a damaged tooth, and protect it from future decay.
Typically our crowns are one of 4 materials:
Our most popular crown is our same-day CEREC ceramic crown. CEREC stands for Chairside Economical Restoration of Esthetic Ceramics, and is the latest technology in crowns. Using computer-aided design and manufacturing (CAD/CAM), we can produce a custom-fitted crown for you in a same-day procedure!
Crowns can last anywhere from 5 to 15 years, with proper care. We will show you tips on how to make your crown last as long as possible.
When a tooth has a moderate to large amount of decay, but has 3 to 4 walls that are free of decay and thick enough to support biting forces, an inlay can be used instead of a full crown. If the tooth has 1 to 2 walls that are decay-free and thick enough, an onlay can be used to cover the affected walls and cusp tips instead of a full crown. Typically, these are made of porcelain or porcelain/zirconia-infused composite hybrid material and are made in 1 visit in the office.
First, the tooth is completely numbed and all decay is removed. If too much of the core of the tooth is missing, it is replaced with a filling called a core build-up. A thin outer shell of the tooth is reduced so that a new porcelain shell can cover the tooth without adding to its size.
The prepared tooth is then digitally scanned with a state-of-the-art, highly-accurate video scanner. The image is then integrated into the latest software, and we custom design a crown to perfectly fit the prepared tooth as well as mimic the look and function of the surrounding teeth. The design is then transferred to our in-office crown mill where the crown is made, and then sintered.
The fit of the crown is verified to be exact with an x-ray, prior to cementing. Then the crown is permanently cemented, a final x-ray is taken to show complete seating, and the cement is cleaned up. Your bite is checked and adjusted if needed until it feels good to you.
