Dental crowns restore damaged teeth. A crown covers the visible portion of a tooth, and it protects the structure above the gumline. When a tooth has decay or damage, a crown can cover and support it. The crown fits over the existing tooth structure. It remains fixed in place. Because the natural tooth structure stays underneath, the crown provides coverage, and it restores the visible surface. The placement process uses a prepared tooth, and the final crown sits securely over it.
Understanding Dental Crowns
A dental crown is a tooth-shaped cap. A crown covers a damaged tooth, and it restores the visible portion. When a tooth has a large filling, a crown can cover it, and it adds support. Crowns also cover teeth that are broken or worn. A dental bridge replaces a missing tooth. It uses adjacent teeth for support, and crowns hold the bridge in place. Because the crown fits over the existing tooth structure, it stays securely in position, and it covers the exposed surface.
Exploring Crown Materials
Dental crowns use several materials. Common options include metal, porcelain, and resin, and each type serves a specific purpose. Some crowns combine materials. Porcelain-fused-to-metal crowns include a metal base with a porcelain exterior. A dental bridge also uses crowns. It relies on crowns placed on adjacent teeth, and it fills the space of a missing tooth. Because different materials are available, a crown can match the surrounding teeth, and it restores the visible surface.
Dental bridges replace missing teeth. Dentists place them on adjacent teeth, and these crowns support the bridge. The bridge includes a false tooth that fills the gap. It restores the visible space. Bridges use crowns for support. Because the structure relies on nearby teeth, the bridge stays in position, and it spans the open area. Dentists may also use implants when additional support is needed.
Anticipating the Procedure
The installation process begins with an examination. The dentist numbs the tooth with a local anesthetic, and they numb the surrounding gum tissue. After the area is numb, the dentist files the tooth, and they shape it to hold the crown. Providers take an impression of the prepared tooth. Because porcelain crowns require fabrication, the lab needs a few weeks, and the patient waits for the crown. Zirconia crowns take less time. Dentists make zirconia versions in the office, and they place the crown during the same appointment.
Bridge installations require multiple visits. The dentist shapes the abutment teeth first, and they take an impression of the area. While the laboratory constructs the permanent bridge, the patient receives a temporary version, and this temporary piece protects the adjacent teeth. The temporary bridge supports the remaining teeth. The patient returns for a second visit later. When the patient arrives, the dentist confirms the fit, and they cement the permanent bridge securely into place.
Find a Clinic
Dental crowns and bridges repair damaged teeth. Crowns provide structural support for weakened or broken teeth, and they cover the visible portion of the tooth. Bridges replace missing teeth, and they fill the gap left by absent teeth. Crowns and bridges rely on the adjacent or underlying teeth for support, and they restore the structure of the mouth. Dentists perform these procedures using standard techniques, and the components are placed securely over the prepared teeth. Find a clinic in your area to learn more.
