Dental crowns are durable covers made of very hard materials that are placed over the entire tooth to help provide strength and protection as well stop any further decay or damage following a root canal. They can also be used to hide deep discoloration, chips and other cosmetic issues. Crowns are custom-fit for your tooth and can be tinted to match the neighboring teeth so they look and feel completely natural.
Crowns are used whenever the structure of a tooth needs extra support and strength, such as when a tooth has a very large cavity or a large portion of the tooth has broken away. They're also usually used following a root canal to help provide strength and preserve the tooth, and to hide deep discoloration following a root canal or trauma. Crowns are also applied to the teeth that are used to support a bridge, providing added strength as well as reducing the risk of damage at the points where the bridge is attached to the supporting teeth.
Crowns are applied in two visits. During the first visit, the tooth is prepared and an impression is made to serve as a model for the crown. A temporary crown may be applied to protect the tooth. At the second visit, the crown is adhered using a very strong bonding agent.
Crowns are extremely durable and with proper care, they can last for many, many years. To help extend the life of your crown, brush and floss regularly and see the dentist on a routine basis to ensure it remains properly seated on your tooth, and also avoid chewing on hard candies or ice or eating very sticky foods that can cause the crown to become damaged or dislodged.
