Why use a stainless steel crown instead of just a white filling?
Primary teeth have very thin enamel compared to the permanent teeth. For this reason, they do not hold big fillings well. Big fillings are repairs to large cavities on two or more sides of the tooth on first primary molars, and three or more sides on the second primary molars. Additionally, children who grind their teeth at night break their fillings much more rapidly. Stainless steel crowns hold up much better under these circumstances.
