If you have had a root canal or large filling in the past, chances are you are well aquatinted with dental crowns. But why are crowns dental crownsneeded? What do they do? Your St. Louis, MO dentist at Advanced Dental Arts can help you understand this crucial procedure.

What are crowns? 
Dental crowns are a cap-like restoration placed over the top of a tooth. Crowns stabilize and support a weakened tooth and restore its shape, size, and color. Crowns are also used to improve a tooth’s appearance. A dental laboratory customizes each crown based on a mold of your mouth. Additionally, each crown is color-matched to your surrounding teeth. These measures ensure a natural appearance.

What are crowns used for? 
Teeth are incredibly strong and durable but do weaken due to trauma or decay. As the decay continues, it eats into and destroys the tooth’s enamel, creating a hole in the tooth. Once your dentist removes the decay, such as during root canal therapy, there is often more filling than tooth left behind. A dental crown placed over this large filling protects the tooth’s original structure. Crowns also restore a broken or cracked tooth and prevent the break or crack from becoming larger. If a tooth is misshapen, heavily discolored or overlapping another tooth, a crown improves the tooth’s appearance.

What is the difference between temporary and permanent crowns? 
Before your dentist fits your dental crown, they must prepare the tooth to receive the crown. This process involves shaving down the enamel to make room for the crown. The tooth becomes the same shape as the inside of the crown, creating a perfect, snug fit. Traditionally, crowns are fitted in two dental appointments. The dental laboratory which creates your crown needs time to design and carve the restoration, hence the time between appointments. However, the tooth is prepared at the first appointment, requiring a temporary crown to protect the tooth until the permanent crown arrives. At the second appointment, the temporary crown is removed and replaced with the permanent crown.
