Answer 7

stainless steel crowns can be used for primary (baby teeth) to fill in that space until the permanent tooth erupts.  If that space is not filled it will cause the other teeth to move into that space and more than likely braces will be needed. In adults the caps are used to cover extremely bad cavities, over calcified teeth, after a pulpotomy(removal of pulp in crown part) or pulpectomy(removal of the entire tooth and pulp), and for fractured teeth.
