4 Ideal Types of Materials for Dental Crowns

The dental crown is a prosthetic used to restore the structure and function of a damaged tooth. It can be used on cracked, chipped or extensively decayed teeth which cannot be reinstated through any other process.

The crown is designed like a tooth-shaped cap which encases the visible part of the tooth, above the gum line. Your dentist can recommend this procedure after root canal surgery or installation of a dental implant. In addition, the dental crown can cover a tooth with extensive, hold dental bridges and restore the oral aesthetics.

If you are expecting this treatment, you will need to choose your ideal crown fabrication material. Here is a short description of the main types of materials.

Porcelain Crowns

Pure porcelain crowns are advantageous because their colour is an ideal match for the natural teeth. They are also not linked to any allergies so they are suitable for people with sensitive physiology. On the other hand, they are relatively weaker than metal-containing alternatives and they tend to wear down the natural opposing teeth. Still, this is the best choice for restoring damaged front teeth.

Porcelain and metal Crowns

These crowns are made by fusing porcelain veneers to strong metal shells through high heat treatment. The metal provides structural strength so they are more durable and resilient compared to porcelain alternatives. The porcelain veneer presents a somewhat natural tooth-like appearance so it is a suitable choice for front and back teeth. The primary drawback linked to these crowns is the risk of compromising the dental aesthetics. Sometimes, the dark metal shell may be exposed along the gumline, especially if your gum tissue starts to recede.

Gold Crowns

Gold crowns are made from a strong alloy consisting of gold, copper as well as other metals. The material durable and it adheres well to the natural tooth structure. In addition, it is very compatible with the gum tissues and it is not known to wear down the teeth in opposing dental arches. They are suitable for installation on molars because the metallic colour is not cosmetically pleasing. You should also note that gold crowns are considerably expensive compared to most alternatives.

Base Metal Alloy Crowns

These crowns are made from non-noble metals such as nickel or chromium. The base metal alloys are designed to provide strength and general resilience to the crown. They are also long-lasting, resistant to corrosion and they are gentle on opposing teeth. Like gold, their only disadvantage is the metallic colour which makes them unsuitable for covering front teeth.
