A crown 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. Porcelain crowns are the most popular, as they resemble your natural teeth, are highly durable and will last many years if properly cared for. Made to match the shape, size, and color or your teeth, porcelain crowns give you a natural, long-lasting and beautiful smile.
