Crowns are “cemented” onto an existing tooth and fully cover the portion of the tooth above the gum line. In effect, the crown becomes the tooth’s new outer surface. Stainless steel dental crowns are considered a good temporary restoration to save a primary tooth until the permanent tooth can erupt and take its place. Keeping the primary tooth if at all possible is very important. A primary tooth can be restored with a stainless steel crown during one appointment. A crowned tooth must be brushed and flossed just like other teeth.
