- Zirconia (white) and stainless steel (silver) crowns are both strong and last until the baby tooth falls out.
- Zirconia looks natural but needs more tooth shaping and a clean, dry area; stainless steel fits very broken-down teeth more easily.
- The dentist chooses tooth by tooth, and tells you where your preference fits.
When a baby tooth has a cavity that is too big for a filling, or it has had a baby root canal, the dentist usually covers it with a crown. For children, there are two common choices: white zirconia crowns and silver stainless steel crowns. Parents often ask which one is better. The honest answer is that both work well, and the right choice depends on the tooth. This guide explains how they differ and how a pediatric dentist decides.
Why baby teeth need crowns at all
It's natural to wonder why a tooth that will fall out someday needs a crown. Baby molars usually stay in the mouth until around ages 9 to 12. They help children chew, speak, and hold space for the adult teeth underneath. A large cavity that is only filled can break down again, and decay that spreads can lead to pain or infection. A crown covers every surface of the tooth, so it protects the tooth until it falls out on its own. When it does, the crown comes out with it.

What each crown is
are pre-formed caps made from a strong, tooth-colored ceramic. They look like natural teeth, which is why many parents prefer them, especially for front teeth and back teeth that show when a child smiles.
are pre-formed silver caps. They have been used in pediatric dentistry for decades and are a well-proven, durable way to restore baby molars.
Both are strong, both cover the whole tooth, and both are meant to last until the baby tooth is naturally lost.
How the two compare
zirconia is white and blends in. Stainless steel is silver and visible when the child opens wide.
stainless steel crowns can be trimmed and gently shaped to hug the tooth. Zirconia crowns are rigid and can't be bent, so the tooth has to be shaped to fit the crown. That usually means removing a bit more tooth structure.
when a tooth is very broken down, or the space is tight because neighboring teeth have shifted, a stainless steel crown is often easier to fit securely.
zirconia crowns are cemented in a way that works best when the area is kept clean and dry, with bleeding gums under control. That is easier when a child is asleep and still, as in treatment under general anesthesia.
stainless steel contains nickel. If your child has a known nickel or metal allergy, tell the dentist so they can plan around it.
How a pediatric dentist chooses for each tooth
The decision is made tooth by tooth, not once for the whole mouth. A child may end up with white crowns on teeth that show and silver crowns on back molars that are badly broken down. The dentist looks at:
- where the tooth is and how visible it is when your child smiles and talks;
- how much healthy tooth is left after the decay is removed;
- the space available and how the child bites;
- whether the gums around the tooth are healthy enough for a good seal;
- your family's preferences, which the dentist will discuss with you before treatment.
If zirconia is your preference, say so at the consultation. The dentist will tell you which teeth it suits and where stainless steel would be the more reliable choice. Insurance coverage for each type varies by plan, so it's also worth asking how your plan treats them.
Crowns placed during treatment under general anesthesia
At littleGRINS, crowns are placed while your child is asleep, in a hospital or surgical-center operating room, with a board-certified medical anesthesiologist caring for your child throughout. All the needed work, such as fillings, nerve treatment, and crowns, is usually completed in one visit, and your child goes home the same day. Learn more about how pediatric sedation dentistry works, or read our before and after surgery guide to see how to prepare.
After treatment, brush crowns just like natural teeth, paying attention to the gumline, where plaque can still build up. Your child keeps seeing their regular dentist for checkups. If you have questions about which crown is right for your child, request a free consultation or call (917) 979-6579.
