A crown (or cap) is a covering that encases the entire tooth surface, restoring it to its original shape and size. A crown protects and strengthens tooth structure that cannot be restored with fillings or other types of restorations.
There are several types of crowns, porcelain (tooth colored crown) are the most life like in appearance. They are highly durable and will last many years, but like most dental restorations, they may eventually need to be replaced. Porcelain crowns are made to match the shape, size, and color of your teeth, giving you a long-lasting, beautiful smile. State of the art ceramic crown options are e.max., Captek, and Zirconia Oxide. Crowns made of gold alloy are the most durable of all restoration options, especially on molars subjected to the greatest chewing pressures. Gold is still the material to which all restorative materials are compared.

What does getting a crown involve?
A crown procedure usually requires two appointments. At the first appointment, under local anesthesia, the dentist will prepare the tooth by removing any decay, shape the surface of the tooth specifically for the type of the crown selected. Highly accurate molds (or impressions) will be taken to create your custom crown. A transitional (temporary) crown will be made and placed over the prepared tooth.
At your second appointment, your temporary crown will be removed, the tooth cleaned, the bite and shade will be checked, and the new crown will then be permanently cemented.
You will be given care instructions and encouraged to have regular dental visits to check your new crown.
