Teeth that have been damaged, worn, or suffered major decay can be totally restored to their original beauty and functionality with a crown. Crowns, known also as ‘caps’, are ideal not only for enhancing the appearance of a damaged tooth, but for protecting the remaining root and tooth soft tissue as well. Crowns are made of porcelain or precious metals, or a combination of these materials. Crowns are also used to cover discoloured fillings and to add strength to a weakened tooth.
