Is your tooth broken? Missing smile? Restore Dental Crowns. Explore temporary dental crowns, cost, tooth cap, and options for front teeth or full mouth. Among the several types of crowns, porcelain crowns (tooth-colored crowns) are the most popular and widely used. They are highly durable and will typically last many years, but like most dental restorations, they may eventually need to be replaced at some point in time. Porcelain crowns are purposely made to match the contour, size, and color of your teeth and give you a natural, long-lasting beautiful smile.
