A crown is a cap or a covering that is fitted on the entire tooth. It replaces the tooth’s outer enamel. Crowns are made from different materials including resin, metals, or porcelain. Your tooth might need a crown for several reasons including:
Root Canal. Crowns are typically used after a root canal treatment to restore the tooth’s stability. A root canal removes the infected pulp, blood vessels. and nerve rom the tooth leaving the tooth hollow. If nothing is covered over the tooth, it may become brittle and crack.
Large Decay. When a tooth is badly decayed, it forms a large cavity that destroys the enamel and dentin. When a filling is used to cover the cavity, a crown is used to strengthen the tooth’s structure and give the tooth its chewing functionality.
Cracked Tooth. If you have a tooth crack that has not extended to the root or the nerve, the best way to prevent the crack from spreading is by getting a crown. The crown acts as a protective cover functioning just as the enamel would.
