There are several reasons why a person might need a dental crown. Crowns are used to protect weak teeth, to support dental bridges, to improve the shape of a tooth, and to cover dental implants. They cover all visible portions of a tooth from the gum line up. Along with the many uses, there are many different types of crowns, each with their own properties.
Metal Dental Crowns are made of metal alloys such as gold, palladium, nickel and chromium. The benefit of this type of crown is that less tooth structure needs to be removed in order to place the crown. Furthermore, damage and wear to opposing teeth is kept to a minimum. The main issue that people find with metal crowns is the color. Metal crowns are more easily noticed than other types of crowns. Due to this reason they are a great option for teeth that remain unseen.
If you are looking to provide the closest match to natural teeth color than a good option is a dental crown made entirely from ceramic or porcelain. This type of crown is generally used on front teeth due to the color match it provides. As opposed to metal crowns they cause more wear on opposing teeth and are not as strong.
There are several other types of crowns including ceramic/metal combinations. No matter which condition a person chooses a crown for there is no doubt that the invention of the dental crown was significant for the field of dentistry.
