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.
