What are Dental Crowns?
Crowns are prosthetic tooth-shaped porcelain caps that change the colour and shape of your teeth. They are used to fix a broken or decayed tooth, retaining as much of your natural tooth as possible. The therapeutic purpose of crowns is to rebuild and strengthen your teeth to restore oral function and avoid further infection or damage.
Crowns can also be used to change the shape of a tooth, hold a dental bridge in place, or cover an implant. These dental caps are commonly used to replace a tooth after root canal treatment. Crowns can be made with porcelain and those replacing more hard-wearing teeth can be made with stronger materials such as porcelain-fused-to-metal or gold.
Teeth Capping Options
Natural Looking Porcelain Crowns
Dental crowns made from porcelain can significantly improve the appearance of your teeth and are therefore the most popular type of crown used for teeth restorations. Porcelain teeth are colour-matched and designed to blend with the shape and size of your other teeth. They are biocompatible, meaning they are free of metal, and toxin free. They are not as strong as metal crowns, but can last a long time if properly cared for.
Porcelain fused-to-metal crowns provide a balance between strength and aesthetics. The porcelain-coated cap displays the natural-looking tooth and the metal structure provides extra strength to the tooth. The disadvantage of porcelain fused to metal crowns is that they may form a dark line at the gum line over time.
Gold crowns are made from a combination of metal to provide strength and durability. They are generally used for back teeth restorations as they are long-lasting and require less of the tooth to be removed. Metal crown tooth restorations are less popular due to their less attractive dental aesthetics. However, patients with untreated bruxism, commonly known as teeth grinding, or those who clench their jaw would be advised to opt for gold crowns.
