Crowns
What is a Dental Crown?
A dental crown is a tooth-shaped cap placed over a damaged or weakened tooth. Dentists use crowns to restore teeth that are broken, decayed, fragile or cracked. The crown fits snugly over the entire tooth and is cemented in place. Before placing the crown, a dentist will remove a small layer of enamel to ensure a proper fit. Dental crowns in Washington, DC are made from a variety of materials, such as resin, metal, and porcelain.
When Might You Need a Dental Crown?
Crowns serve various purposes, including:
- Strengthening a weakened tooth
- Protecting and supporting a cracked tooth
- Restoring a worn-down or broken tooth
- Holding a dental bridge in place
- Covering a tooth treated with a root canal

- nings and checkups

Types of Dental Crowns
There are several types of dental crowns, each tailored to your personal needs and preferences:
- Metal Crowns: Made from metals like gold, palladium, nickel, and chromium, these crowns are strong, durable, and less likely to chip. They last the longest and require minimal enamel removal. The primary downside is the metallic color, making them suitable for out-of-sight molars.
- All-Ceramic or Porcelain Crowns: These crowns closely resemble the natural appearance of teeth and are ideal for those with metal allergies. Zirconia, a durable material, is commonly used for ceramic crowns. These crowns are gentle on opposing teeth and highly durable.
- All-Resin Crowns: Resin crowns are less expensive but are more prone to damage compared to other materials. They are often used for temporary crowns.
Dental Crown Procedure
A dental crown typically requires two visits to the dentist:
First Visit:
- Tooth Preparation: Your dentist will remove some enamel to create space for the crown, ensuring it stays securely in place. Sometimes, a filling material is used to build up parts of the tooth.
- Impressions: scans of your teeth will be taken digitally. These are sent to a dental lab to create your custom crown.
- Temporary Crown: While waiting for the permanent crown, your dentist will place a temporary crown made of resin.
Second Visit: Once the lab finishes your crown, you’ll return to your dentist:
- Your temporary crown will be removed.
- The dentist will check the fit, color, and shape of the new crown. An x-ray will be taken to ensure the fit of the new crown.
- The permanent crown will be bonded securely to your tooth.
