Dental crowns protect the natural tooth and improve the appearance of the smile. Porcelain can be shaped to mimic the appearance of a natural crown which is why it is highly preferred in cosmetic dentistry. The crowns look very natural. They have a characteristic of translucency which is why they are bright giving them an esthetic edge. They can be used to protect damaged tooth, severely decayed tooth or discolored tooth. Their bio-compatibility is another added benefit. These crowns are more likely to be used when restoring front teeth.
