A stainless steel crown (SSC) is a pre-formed, full-coverage metal cap crimped over a badly decayed primary tooth. It has been the gold standard in pediatric dentistry for over 50 years because it is fast, durable, cost-effective, and survives a child's unpredictable oral environment far better than tooth-colored alternatives. An SSC placed today will last until the baby tooth naturally exfoliates — typically in 3–7 years — without needing replacement. Despite its silver appearance, it is the most evidence-backed restoration for primary molars.
Baby teeth are not disposable — they hold space for permanent teeth, support jaw development, and are essential for chewing and speech. When decay in a primary molar is too extensive for a filling to last reliably, an SSC is the most clinically sound solution. Fillings in heavily decayed baby teeth have significantly higher failure rates than SSCs; a failed filling may require re-treatment or extraction, causing space loss and downstream orthodontic problems. The SSC resolves the problem definitively in one visit.
An SSC is indicated when decay involves multiple surfaces of a primary molar, when the tooth has undergone a pulpotomy or pulpectomy and needs full-coverage restoration, when the child has high cavity risk and composite fillings have repeatedly failed, or when tooth structure is insufficient to support a filling with adequate longevity. It is the restoration of choice following any pulp therapy on a primary molar.
