Crowns are full coverage restorations used to cover a tooth that is likely to break, or is too broken down to be restored with a filling. Crowns are recommended for teeth that have received root canal treatment, or when a large filling wears out. The greater the damage done by tooth decay, the more likely a crown will be needed. Even after a filling is put in a large cavity, a tooth is more likely to break. Because the jaw muscles are the strongest in the human body, teeth are subjected to tremendous pressures. Crowns completely cover teeth providing strength and protecting the tooth against fracture. Without the protection of a crown, suseptible teeth can crack or break and require extraction.
Like veneers, crowns can improve your smile. The shape and color of a crown is completely under your control. A crown can be made for a tooth in two appointments. During the first visit decay is removed from the tooth and it is shaped to accept the crown. An impression is made of the prepared tooth for use in fabricating the crown. A dental laboratory fabricates the crown from high-strength porcelain over gold alloy, all ceramic material, or gold. During this time a temporary crown is worn. In the second visit the temporary crown is removed and the permanent crown is adjusted as needed and cemented in place.
