Dental restorations restore the function, integrity, and morphology of missing tooth structure, which can be caused by caries or external trauma, such as chipping or cracking a tooth. A crown is a restoration that covers (or “caps”) a tooth to restore it to its normal shape and size, which can strengthen and improve the appearance of the tooth. Crowns are necessary when a tooth has been damaged significantly and cannot be adequately restored with a filling. A crown can protect a weak tooth from fracturing; it also can prevent a cracked tooth from further damage and can cover discolored or misshapen teeth for more aesthetically pleasing smiles.
Numerous factors are considered when determining the crown material that is best for your tooth, including the color, bite, shape, space, and location of the tooth in your mouth. Fabrication of a crown usually requires two dental visits. The first visit involves an examination of the tooth to determine how it should be restored and preparation of the tooth for the restoration and the second visit usually involves delivery of the final restoration.
