A dental crown or cap
is a tooth-shaped cover that is placed over a weakened or damaged tooth to restore its natural appearance and prevent further deterioration. Crowns are used in cases of severely chipped or broken teeth, to cover the exposed area of a tooth following a root canal procedure, to replace a large old filling or for cosmetic reasons. When a filling is not a viable solution to correcting the damage sustained by a tooth, crowns can provide a long-term solution to restoring the function of your teeth and enhancing the appearance of your smile.
Crowns can be made of all metal, all porcelain, or a combination of both. Because all crowns are custom made for each patient, it may take more than one appointment to complete. At your first visit, the area is numbed to make you comfortable. Your dentist will use a dental hand piece to shape and prepare the tooth so that the crown can properly fit over it. Next, impressions are taken of the prepared tooth.
