Types of dental caps available
Metal Crowns - One of the more common and affordable forms of tooth cap is the metal crown. Strong enough to withstand bite force, metal crowns are seen as the more sustainable permanent crown option over porcelain crowns. However, due to their metallic nature, the metal crown is unsightly and obvious when smiling and can make the tooth look black in appearance.
All ceramic or all porcelain Caps - The less sustainable of caps, yet more visually appealing is the porcelain cap. Tooth-like in appearance, the porcelain cap will blend in more naturally with the surrounding teeth. However, the porcelain crown is far more susceptible to breakage.
Porcelain-fused-to-metal Cap - A mixed hybrid version of the porcelain cap and the traditional metal cap, the porcelain-fused-to-metal cap is a becoming a more popular choice in the dental cosmetic industry as it provides the natural look of a normal tooth and the sustainability of a metal tooth.
However, as the outer shell of the cap is porcelain, the black inside of the cap can be seen when the porcelain chips away. Dentists will often dismiss this issue as they will deem the task un-important.
Temporary Crown - Usually temporary crowns are provided to patients whilst their permanent crown is being designed in a dental laboratory. These crowns are not a long term and sustainable solution as the cap is made from an acrylic based material.
