A dental crown is a custom-fabricated restoration designed to encase the entire visible portion of a tooth. Crowns are typically recommended when a tooth is severely worn, cracked, or has insufficient structure to support a standard filling. The goal of a crown is to provide structural support and assist in protecting the remaining tooth from further damage.
The choice of material depends on the location of the tooth, the forces of your bite, and your aesthetic goals.
Utilising materials like E-max or Zirconia, these crowns are designed to mimic the light-reflecting properties of natural enamel.
Conservative Preparation: Some modern ceramics allow for a more conservative removal of natural enamel, which helps preserve the integrity of the underlying tooth.
PFMs consist of a metal substructure for strength, overlaid with a layer of porcelain.
Clinical Benefits: They provide significant durability and have been a standard in restorative dentistry for decades.
Considerations: Because the metal core is opaque, these crowns may not possess the same level of transparency as all-ceramic options, making them more common for posterior (back) teeth.
Gold crowns are fabricated entirely from a high-noble metal alloy.
Considerations: Due to their colour, they are typically reserved for molars where they are not visible in the smile.
The clinical success of any dental crown is dependent on a combination of professional monitoring and diligent home care. Regular clinical examinations and professional cleans are essential to ensure the margins of the crown remain healthy and free of decay.
Clinical Assessment: A consultation and diagnostic imaging (X-rays) are mandatory to determine if a crown is the appropriate restorative solution. Not all teeth are suitable for crowning.
Procedural Risks: The preparation for a crown involves the permanent removal of natural tooth enamel. Inherent risks include temporary tooth sensitivity, potential irritation of the dental pulp (which may require further treatment), or gingival (gum) recession at the margin.
Maintenance: Like natural teeth, crowned teeth are still susceptible to decay at the margin and periodontal disease. Meticulous brushing and flossing are required.
Results: Individual results, shade matching, and the longevity of the restoration vary significantly. No specific timeframe for the lifespan of a crown can be guaranteed.
Mandatory Warning: All dental procedures carry risks. Any surgical or invasive procedure carries additional risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner.
