Hearing that your child has a cavity can bring up a lot of questions, and that is completely normal. The good news is that cavities are common, treatable, and far easier to manage when handled early. At Smile Arc Pediatric Dentistry in San Diego, we repair children’s cavities with gentle, kid-focused care, using tooth-colored fillings for smaller cavities and durable crowns when a tooth needs more protection. Below, we explain how we decide between a filling and a crown, what each visit is like, and how we keep your child relaxed from start to finish.
What Happens When a Child Has a Cavity?
A cavity is a hole in the tooth caused by decay, and it will not heal on its own. Once decay breaks through the outer enamel, the affected part of the tooth needs to be cleaned out and the tooth rebuilt so the decay cannot spread. How we rebuild it depends on a few things: how much healthy tooth is left, where the cavity is, how much chewing force the tooth handles, and how deep the decay has reached. We always start by explaining exactly what we see and walking you through the options before any treatment begins.
For everyday prevention and the science behind why cavities form, see our tooth decay and cavities page. This page focuses on how we repair a tooth once a cavity is already there.
Tooth-Colored Fillings for Children
For most small to moderate cavities, a tooth-colored composite filling is all that is needed. The decayed area is gently removed, and the space is filled with a durable, natural-looking material that bonds directly to the tooth and blends in with your child’s smile. Composite fillings are a trusted, widely used option in pediatric dentistry and contain no metal.
Before we begin, we numb the area with local anesthetic so your child stays comfortable, and we can offer gentle sedation such as nitrous oxide for children who feel anxious. Most fillings are completed in a single, short visit.
When Does a Tooth Need a Crown Instead of a Filling?
Sometimes a cavity is too large for a filling to hold reliably, or decay has weakened so much of the tooth that a filling would likely fail or fracture. In those cases, a crown is the better choice. A crown covers the entire visible tooth, restoring its strength and shape and sealing out further decay. Crowns are also commonly placed after nerve and pulp treatment (a pulpotomy) to protect what remains of the tooth.
We will recommend a crown only when a filling truly will not do the job, and we will always explain why.
Types of Crowns We Use for Kids
Children’s crowns come in two main types, and we help you choose the right one for each tooth:
- Stainless steel crowns are pre-formed silver-colored crowns that are exceptionally durable. They are the long-standing standard for back baby molars, where chewing strength matters most and the crown will not be very visible. The American Academy of Pediatric Dentistry recognizes stainless steel crowns as a safe, effective, and well-tolerated restoration for children.
- Tooth-colored crowns (such as zirconia or composite crowns) match the natural color of the tooth and are often chosen for front teeth or when appearance is a priority.
We will talk through the trade-offs, including durability, appearance, and cost, so you can make the choice that fits your child and your family.
What to Expect at Your Child’s Visit
We design every restorative visit around your child’s comfort. First, we numb the area with local anesthetic, and for anxious children we can add nitrous oxide (laughing gas) or discuss other sedation options. We use a gentle, step-by-step approach and explain things in kid-friendly language as we go.
A filling usually takes one short appointment. A crown also typically takes a single visit, since pediatric crowns are pre-sized and placed the same day. Afterward, we will give you simple aftercare instructions, and any numbness wears off within a couple of hours. If this is your child’s first restorative treatment, our first visit page explains how we build trust before any procedure.
Cost & Insurance for Children’s Fillings and Crowns in San Diego
Cost depends on the type of restoration, the size and location of the cavity, and the number of teeth involved, so the most accurate number comes after we examine your child. As a general guide, tooth-colored fillings for children commonly run a few hundred dollars per tooth, and crowns more, but please treat these as planning ranges and not a quote. Most dental insurance plans help cover restorative care for children.
Our team verifies your benefits before treatment, submits claims for you, and gives you a clear estimate up front so there are no surprises. You can learn more on our financial and insurance page.

Frequently Asked Questions
Will my child feel pain during a filling or crown?
We numb the tooth and surrounding area with local anesthetic before we begin, so your child should feel pressure rather than pain. For children who feel nervous, we can add nitrous oxide (laughing gas) to help them relax. Most kids are surprised by how easy it is.
How do you decide between a filling and a crown?
It comes down to how much healthy tooth remains. A filling works well when there is enough solid tooth structure to support it. When decay is extensive or the tooth is weakened, a crown is needed to cover and protect the whole tooth so it does not fracture or decay further.
Are stainless steel (silver) crowns safe for children?
Stainless steel crowns are recognized by the American Academy of Pediatric Dentistry as a durable, biocompatible, and well-tolerated restoration for children’s teeth. They have been used in pediatric dentistry for decades, especially on back molars where strength matters most.
Can my child get a tooth-colored crown instead of a silver one?
Yes. We offer tooth-colored crowns, such as zirconia, that match the natural shade of the tooth. These are a popular choice for front teeth or when parents prefer a more natural look. We will help you weigh appearance, durability, and cost for each tooth.
Do baby teeth with fillings or crowns still fall out normally?
Yes. A filling or crown on a baby tooth is designed to protect it until it naturally falls out on its own schedule. When the permanent tooth is ready, the restored baby tooth comes out just like any other.
How long do children's fillings and crowns last?
With good care, a filling can last for years, and a stainless steel crown often protects a baby tooth for the rest of its life in the mouth. Daily brushing and flossing and regular checkups help every restoration last as long as possible.
