Crowns are provided to restore front and back teeth that have large unsightly and weak fillings, and teeth that are discoloured, broken or crowded. Crowns are made individually for each patient in selected premium dental laboratories. There are several types of material available, and your dentist will advise you of what is suitable for your specific needs. Newer all-ceramic crowns, such as the E-Max pressed ceramic system, allow light to pass through the crown and tooth so it is reflected naturally and ensures a natural life-like appearance. As there is no metal content present, there is no corrosive black line at the margin making it more bio- compatible and aesthetic but still incredibly strong.
