Permanent crowns are the preferred treatment in scenarios where tooth decay has destroyed most of the original healthy tooth structure. Whether a traumatic event has caused damage, or there has been severe enamel erosion, crowns are a comprehensive option to restore the tooth and smile. Crowns are also a feasible option for patients who have trouble grinding and clenching their teeth and have compromised the original structure of their teeth. Marina Del Rey Dentistry also recommends the installation of crowns over teeth that have undergone an endodontic root canal. A tooth that has had its root removed no longer has nerves or life, which makes it very delicate and needs protection. A crown protects weakened teeth from breakage and further damage. Crowns are developed using various materials, such as ceramic, full metal (precious or non-precious), porcelain fused to metal, and/or resin. Permanent crowns are cemented to a tooth and are not removable.
