Gentle Cavity Fillings for Kids in Las Vegas, NV
Finding out your child has a cavity can bring up a mix of feelings, from worry about whether it will hurt to guilt over the juice boxes. Take a breath. Cavities are one of the most common health problems in childhood, and a small one caught early is usually a quick, simple fix. At Smile Sprouts Kids Dental, we provide cavity fillings for kids in Las Vegas, NV, using a calm, step-by-step approach that helps children feel safe in the chair. Whether your child has their first spot of decay or a filling that needs replacing, we'll explain what's happening and what comes next in words everyone can follow.
A filling removes the decayed part of a tooth and replaces it with a strong material that seals the area and restores its shape. For most children, we use tooth-colored fillings, which work well for small or moderate cavities when enough healthy tooth remains around the damaged spot. The visit starts with an exam and a conversation with you about what we see. Then we help your child get comfortable, numb the tooth when needed, gently clean out the decay, and shape the new material to match the tooth. Most single fillings take about 20 to 45 minutes. When decay runs deeper, a filling may not be enough, and options like pulp therapy or a crown, part of our broader restorative dental care for kids, come into the picture.
What Is a Tooth-Colored Filling for Kids?
A tooth-colored filling is a repair made from a natural-looking material that blends in with your child's tooth instead of showing up as a dark spot. Most are made from composite resin, which is why they're also called composite fillings. The resin goes on in thin layers and is hardened with a special light. Because it bonds directly to the tooth, the dentist can often remove less healthy tooth structure than older metal fillings required. Parents often ask for white fillings for children because nobody wants a silver spot showing up in school photos. Just as important, the material seals the tooth well, which helps protect it from new decay starting around the edges.
Do Cavities in Baby Teeth Really Need Fillings?
In most cases, yes. A baby tooth cavity doesn't stay put. Decay moves faster through baby teeth because their enamel is thinner than adult enamel, and a small spot can reach the nerve in a matter of months. Some back baby teeth stay in place until age 10 to 12, so a cavity in a four-year-old's molar has years to cause trouble. There are exceptions. A very small spot on a tooth that's about to fall out, or early weak areas that may harden again with fluoride, may only need monitoring. Our dentists will tell you which situation your child is in and why.
What Filling Materials Are Used for Children's Teeth?
The most common materials for children are tooth-colored, and the best choice depends on the tooth, the size of the cavity, and how well your child can stay still. Here's how the main options compare:
- Composite resin: tooth-colored, strong, and well suited to small and medium cavities on front or back teeth
- Glass ionomer: tooth-colored, releases a small amount of fluoride, and works well near the gumline or for kids at high risk of new cavities
- Silver amalgam: a durable metal option some offices still use for back teeth, though many families now prefer tooth-colored materials

What Happens Step by Step During a Child's Filling?
A filling visit follows a clear order so nothing feels rushed or surprising. Here's what typically happens:
- An exam and a quick chat with you about the tooth and the plan
- Kid-friendly explanations so your child knows what each tool does
- Nitrous oxide, if appropriate, to help an anxious child relax
- Numbing gel, then numbing medicine to keep the tooth comfortable
- Gentle removal of the decay
- Placing and shaping the filling, then hardening it with a light
- A bite check and aftercare instructions for home
Dr. Justin and Dr. Charlene talk your child through each step and stop for breaks whenever needed.
Does Getting a Filling Hurt?
Most kids feel little to no pain during a filling because the tooth is numbed first. A numbing gel goes on the gums before the injection, so the pinch is small, and many children barely notice it, especially when they're watching the ceiling TV or relaxing with nitrous oxide. During treatment, your child may feel pressure, vibration, or water spray, but not sharp pain. Afterward, the lip or cheek may feel puffy and numb for an hour or two. Mild soreness around the gum or a bit of sensitivity to cold can last a day or so and usually fades on its own.
How Long Does a Filling Appointment Take?
A single small filling usually takes about 20 to 45 minutes, including time to numb the tooth and help your child get comfortable. Several fillings in one visit, or a larger cavity, can stretch the appointment closer to an hour. We plan the length around your child's age and attention span. For a young child with multiple cavities, splitting treatment into two shorter visits often goes better than one long one. When a lot of work is needed and a child can't sit for it comfortably, we may talk about sedation options so everything can be done safely and with less stress.
When Is a Crown a Better Choice Than a Filling?
A crown is usually the better choice when a cavity is too large for a filling to hold up well. If decay has hollowed out much of a baby molar, or has reached the nerve and required pulp therapy, a filling may crack or fall out under chewing pressure. In those cases, a crown covers the whole tooth and protects it until it falls out naturally. Crowns are also common for children with decay on several surfaces of the same tooth, or for kids at high risk of new cavities, since a crown leaves fewer edges where decay can sneak back in.
How Should My Child Eat and Care for Teeth After a Filling?
Your child can usually eat once the numbness wears off, which helps them avoid biting their lip, cheek, or tongue by accident. A few simple habits help the new filling last:
- Start with soft foods like yogurt, pasta, or bananas for the rest of the day
- Watch younger kids closely while they're still numb so they don't chew on their lip
- Brush gently twice a day with a fluoride toothpaste, including around the filled tooth
- Floss once teeth touch, and limit sticky candy and sugary drinks
- Call us if the bite feels uneven or soreness lasts more than a few days
A filling repairs one tooth, but home habits protect all the others.
How Long Do Fillings Last in Baby Teeth?
A well-placed filling in a baby tooth often lasts until the tooth falls out on its own, which might be several years away. How long it holds up depends on the size of the original cavity, the material used, how hard your child chews, and how well the area is kept clean. Small fillings in kids with good brushing habits tend to last the longest. Large fillings, grinding, or new decay at the edges can shorten their life. We check every filling at routine visits, and catching wear early means a quick touch-up rather than a bigger repair later.
How Much Do Children's Fillings Cost?
The cost of pediatric dental fillings depends on the number of fillings, the size and location of each cavity, the material used, and whether X-rays or nitrous oxide are part of the visit. Because every child's needs are different, we share a clear estimate after the exam instead of a one-size-fits-all price. Many dental plans cover fillings for children as a basic service, and our team can help you check your benefits before treatment. Treating a cavity early is almost always less expensive than waiting until it needs a crown or pulp therapy.
