A dental crown is a “cap” that’s shaped to cover a tooth to restore its shape and size and your ability to chew with it. Once a crown is bonded in place, it fully encases the visible part of your tooth above the gum line. They’re usually made of porcelain and are used to restore the function and appearance of your tooth after a restoration, such as a root canal. They can also be used to restore teeth that are severely decayed, for attaching bridges, covering implants, or improving the appearance of stained teeth.
Crowns can be made from several different types of materials, including:
- Stainless steel. These are typically used as temporary crowns while the permanent crown is being fabricated from another material.
- Gold, nickel or chromium alloy. When using metal crowns, less of the original tooth needs to be removed, and they withstand biting well. Metal crowns typically last the longest.
- Porcelain-fused-to-metal. These crowns can be matched to look like your natural teeth. However, this type of crown can wear down opposing teeth faster compared to metal or resin crowns.
- All-resin. These are typically less expensive than other crown types, but tend to wear down faster and are more prone to fractures than porcelain-fused-to-metal crowns.
- All-ceramic or all-porcelain. These types of crowns can give you the best natural color match and are often used in patients with metal allergies. They are typically used for restoring front teeth.
Typically, a tooth receiving a crown must be reduced in size. From there, an impression of the tooth is taken in order to make a custom-designed crown. The crown is fabricated and then cemented in place.
With proper oral care, a crown should last eight years or longer. Flossing in the area of the crown is vitally important to prevent excess plaque from accumulating around the restored tooth.
