Which crown is esthetic but costlier and requires greater tooth reduction?

Zirconia crowns are the most esthetic among pediatric crown options because they’re tooth-colored ceramic crowns that blend with natural dentition. They require more tooth reduction than metal options to ensure adequate material thickness for strength and a proper fit, since the crown is milled or pressed from a ceramic block rather than being a preformed shell. The fabrication process and material costs make zirconia crowns pricier. In contrast, stainless steel crowns are metal, durable, and need little tooth removal but are not esthetic; polycarbonate crowns are esthetic but not as durable and are generally less expensive; glass ionomer crowns are the least esthetic and least durable. So the crown that’s esthetic, more costly, and needs greater tooth reduction is zirconia.
