Silver crowns for teeth are prefabricated caps made of stainless steel that fit over a damaged or decayed tooth to restore its shape and protect it from further breakdown. Despite the nickname, they contain no actual silver. They’re most commonly placed on children’s baby teeth, though dentists occasionally use them on permanent teeth as well. They cost between $150 and $300 per tooth, making them one of the most affordable and durable crown options available.
What Silver Crowns Are Made Of
The standard “silver” dental crown is an 18-8 stainless steel alloy, meaning it contains roughly 18% chromium and 8% nickel, with iron making up the bulk at around 67%. Small amounts of carbon, manganese, and silicon round out the composition. The chromium is what makes the steel “stainless,” preventing corrosion inside the wet environment of the mouth. These crowns come pre-shaped in a range of sizes so the dentist can select one that fits snugly over the prepared tooth, rather than custom-fabricating a crown in a lab.
Why Dentists Recommend Them for Children
Silver crowns are the go-to restoration for baby teeth that have significant decay, especially when more than one surface of the tooth is affected. A regular filling in a baby molar with large or multi-surface cavities is more likely to fail before the tooth falls out naturally. Stainless steel crowns, by contrast, have a 96% success rate over 12 months and consistently outlast both amalgam and composite fillings in studies tracking primary teeth.
The American Academy of Pediatric Dentistry recommends them in several specific situations:
- After nerve treatment. When a baby tooth needs a pulpotomy (partial nerve removal), the remaining tooth structure is weaker and needs full coverage to hold up.
- Large cavities on multiple surfaces. If decay wraps around two or more sides of a molar and the tooth won’t fall out for at least two more years, a crown protects the tooth far more reliably than a filling.
- Developmental defects. Some children have enamel that formed poorly due to genetics or other conditions, leaving teeth soft and vulnerable. A crown shields the entire tooth.
- Treatment under sedation or general anesthesia. When a child needs to be sedated for dental work, dentists prefer restorations that will last, since a repeat procedure means another round of sedation.
- Difficulty keeping the tooth dry. Fillings bond best to dry tooth surfaces. In a young, uncooperative child where saliva control is difficult, a silver crown can be placed successfully even in less-than-ideal conditions.
For high-risk children who already show extensive decay, dentists may place silver crowns on teeth that haven’t broken down yet to protect the remaining vulnerable surfaces before new cavities form.
Silver Crowns on Adult and Permanent Teeth
Silver crowns aren’t exclusively for baby teeth. Dentists sometimes place them on young permanent teeth as a semi-permanent solution, particularly when a teenager’s tooth is severely decayed or has a major enamel defect but hasn’t finished growing. In these cases, the stainless steel crown acts as a long-lasting temporary restoration that protects the tooth for years until the patient is old enough for a porcelain or ceramic crown.
For adults, silver crowns on permanent teeth are less common because tooth-colored options look more natural. But when cost is a major concern or the tooth is a back molar where appearance matters less, they remain a practical choice. They’re exceptionally strong, resist wear better than porcelain, and rarely crack or break from chewing forces.
What the Procedure Looks Like
Placing a silver crown typically takes a single appointment. After numbing the area, the dentist removes any decay and reshapes the tooth by trimming about 1 to 1.5 millimeters off the top and slimming the sides slightly so the crown can slide over it. The dentist then selects the smallest crown size that fits the tooth properly, checks that it sits about 1 millimeter below the gumline for a snug seal, and adjusts the edges inward if needed to create a tight fit.
Once the fit is right, the crown is cemented in place with a dental adhesive, and the dentist checks that the bite feels normal. Your child can eat soft foods for the rest of that day, and the crown functions like a normal tooth from that point forward.
There is also an alternative called the Hall Technique, where the crown is pushed over a decayed baby tooth without any drilling or tooth preparation at all. This approach is used when traditional preparation isn’t feasible, often because the child is very young or anxious. The crown seals the decay inside, stopping it from progressing.
How Long They Last
On baby teeth, silver crowns are designed to last until the tooth naturally falls out. With a 96% success rate across studies tracking over 1,400 restorations, they are the most durable option available for primary molars. They outlast amalgam and composite fillings by a significant margin, which is why professional guidelines favor them for teeth that need to stay functional for two or more years before they’re lost naturally.
On permanent teeth, stainless steel crowns can provide functional service for many years, though they’re often eventually replaced with a porcelain or zirconia crown for cosmetic reasons once the patient reaches adulthood.
Cost Compared to Other Crowns
Silver crowns are the least expensive option for pediatric dental crowns. Typical price ranges for children’s crowns break down like this:
- Stainless steel: $150 to $300 per tooth
- Resin: $200 to $400 per tooth
- Zirconia (tooth-colored): $300 to $600 per tooth
- Porcelain-fused-to-metal: $400 to $800 per tooth
Most dental insurance plans cover stainless steel crowns for children, particularly when decay is extensive. The combination of low cost, fast placement, and proven durability is a major reason they remain the standard recommendation despite the availability of tooth-colored alternatives.
Nickel Allergies and Safety
Because silver crowns contain 8 to 13% nickel, parents sometimes worry about allergic reactions. Nickel sensitivity is relatively common in the general population, affecting roughly 30% of adolescent girls and 3% of boys in one Finnish study. The higher rate in girls is largely tied to ear piercing, which is the most common source of initial nickel sensitization.
However, allergic reactions to nickel inside the mouth are rare, even in people who are already sensitized from jewelry or other skin contact. Research has found no evidence that nickel-containing dental restorations alone cause patients to develop a new nickel allergy. For children with a known, confirmed nickel allergy, dentists can use nickel-free alternatives like zirconia crowns instead.
Care After Placement
Silver crowns don’t need special cleaning, but they do need consistent care. Decay can still develop around the edges of the crown where it meets the tooth, so regular brushing and flossing around the crowned tooth is essential. Sticky foods like caramels, taffy, and gummy candies should be avoided because they can pull the crown loose. Hard candies and ice chewing pose a similar risk. If a crown does come off, save it and contact your dentist, as it can often be re-cemented.
