A crown is a type of dental restoration that completely encircles the remaining tooth structure or a dental implant. It is necessary to fabricate a crown when there is not enough healthy tooth structure remaining to support filling materials or when restoring dental implants.
Crowns are made of porcelain fused to a metal substrate or can be completely made of ceramic materials.
Crowns are typically used to restore a tooth’s function and appearance following a restorative procedure such as a root canal. When decay in a tooth has become so advanced that large portions of the tooth must be removed, crowns are often used to restore the tooth.
Crowns also serve an aesthetic use and are applied when a discolored or stained tooth needs to be restored to its natural appearance.
