The durability of a dental crown depends on the materials used. This is a list of the available options.
With metal crowns it is best to use gold as it helps keeping the gums healthy and it is easily adjustable. If the crown fits perfectly, it means the access between the crown and the tooth is sealed, blocking the access of bacteria that could otherwise cause cavities and compromise the dental crown.
From an esthetic point of view, the best option is choosing a porcelain crown as it can perfectly imitate the color and aspect of your teeth. The porcelain used today has exceptional quality as it is based on new ceramic materials, such as zirconium and empress 2 that are highly resistant to pressure and look great. Using porcelain crowns you can get the smile of your dreams.
Porcelain on Metal Crowns
This category refers to crowns that have a metal structure and porcelain cover. Metal is very resistant and porcelain can give you the aspect you want. These crowns can be used anywhere in your mouth (front or back), independent on the position of the tooth. The more gold or other noble metal in the structure of a crown, the better it fits in the place helping your gums stay healthier.
Porcelain on Zirconium Crowns
These crowns are highly resistent and especially esthetically pleasing. Unlike some of the other materials that are sometimes used, this does not cause black pigmentation where the edge of the crown meets the gum. This could be your ideal choice, considering the aspect and the strength of this device. With porcelain and zirconium crowns you can get back the pleasant look of your natural teeth and the guarantee of a long lasting prosthetic device that will ensure a better quality of chewing, speaking, and smiling, by restoring all the functions of your compromised tooth. Besides, the crowns made on a zirconium base are less likely to produce allergies and can ensure a better looking transparency effect.
