TL;DR
- Pediatric dental fillings treat cavities in baby and permanent teeth, stopping decay from spreading and protecting the tooth until it falls out naturally or for the long term.
- Baby teeth absolutely need to be filled. Untreated cavities cause pain, spread to neighboring teeth and can affect the incoming permanent tooth below.
- Tooth-colored composite resin is the most common material used today, while stainless steel crowns are used for more severely decayed back teeth.
- The procedure is gentle, short and done under local anesthesia, and most children do better than their parents expect.
- Aftercare is simple: soft foods for a few hours, no hot or cold extremes and good brushing habits to protect the filling.
Does My Child Really Need a Filling on a Baby Tooth?
Yes, and this is probably the most common question parents ask before a pediatric dental filling appointment. Because baby teeth are temporary, it’s easy to assume a cavity can wait until the tooth falls out on its own. The problem is that untreated decay doesn’t stay put. It spreads deeper into the tooth, can reach the nerve and cause significant pain, and can affect the adjacent teeth and the developing permanent tooth underneath.
A pediatric dentist will recommend filling a cavity as soon as it’s identified, not to add unnecessary treatment, but because catching it early keeps the procedure simpler and the child more comfortable. Let’s take a closer look at the materials, process and aftercare.
What Materials Are Used in Pediatric Dental Fillings?
Dental fillings for children are not one-size-fits-all. The material we recommend at Norwood Dental depends on which tooth is affected, how much decay is present, and what will hold up best for that particular tooth. The two most common options are:
- Composite resin (tooth-colored fillings): The most common option for children today. Composite bonds directly to the tooth, preserves more healthy tooth structure, and blends in naturally. It works well for small to moderate cavities in both front and back teeth.
- Glass ionomer fillings: Often used for smaller cavities, baby teeth or very young children. This material releases fluoride over time, which can help strengthen the tooth and lower the risk of future decay. While not as durable as composite or metal fillings, it can be a good option in areas with less chewing pressure.
- Dental amalgam (silver fillings): A durable material that has been used in dentistry for decades, especially for back teeth that handle strong chewing pressure. While less common today because of its silver appearance, it may still be recommended in certain situations.
- Stainless steel crowns (SSCs): Recommended when a cavity is too large for a regular filling, especially on back baby teeth. The crown covers the entire tooth, making it strong and durable for chewing. Though silver in color, SSCs work well for badly damaged primary teeth.
What Does a Pediatric Cavity Filling Procedure Look Like?
For many parents, the anxiety around a pediatric cavity filling is bigger than the actual visit. Here is what a typical appointment at our dental clinic in Norwood involves:
- Numbing the area: A topical gel is applied to the gum before the local anesthetic injection, so most children feel little more than a brief pressure sensation rather than a sharp sting.
- Removing the decay: The dentist removes only the decayed portion of the tooth using a small drill or air abrasion device. Pediatric dentists are trained to work gently and explain each step in child-friendly language to help kids feel comfortable during the treatment.
- Placing the filling: Composite, glass ionomer or amalgam fillings are placed directly into the cleaned cavity and shaped to the tooth. For larger decay, a stainless steel crown is fitted over the tooth for added strength.
- Checking the bite: The dentist checks that the restored tooth sits correctly in the bite before the appointment ends. The whole procedure typically takes 30 to 45 minutes, depending on the size and location of the cavity.
Our expert, Dr. Kristina LeCount, notes that children’s experience at the dentist is shaped largely by how the appointment is framed before they arrive. Parents who describe the visit matter-of-factly, without adding phrases like “it won’t hurt” (which plants the idea of pain) or “be brave” (which signals there’s something to fear), consistently bring in children who are calmer and more cooperative during tooth fillings for kids.
How to Care for Your Child’s Tooth After a Filling
Aftercare for pediatric dental fillings is straightforward. Follow these steps in the hours and days after the appointment:
- Wait 30 to 60 minutes after leaving the office before giving your child anything to eat or drink, to allow the anesthetic to wear off fully and prevent accidental biting of the numb cheek or lip.
- Offer soft foods for the rest of the day: yogurt, mashed potatoes, scrambled eggs or similar. Avoid very hot or very cold foods, which can cause sensitivity around the newly filled tooth.
- Expect some tenderness around the tooth and gum for a day or two. This is normal and typically resolves without medication. Children’s acetaminophen or ibuprofen can be used if discomfort is noticeable.
- Resume normal brushing that evening using a soft-bristled brush. The filling is fully set by the time your child leaves the office.
- Contact the dental office if your child says the bite feels “high” or uneven after the numbness wears off. This is easily adjusted at a quick follow-up and is more common with back teeth.
Getting Ahead of Cavities at Norwood Dental
The best time to address a cavity in a child’s tooth is before it causes pain. Treating a cavity with a pediatric dental filling at an early stage usually means a smaller restoration, less time in the dental chair, and a more comfortable experience for the child.
At Norwood Dental, care is focused on identifying decay early and choosing the most appropriate treatment for each child’s needs. Our pediatric dentist in Norwood, MN, carefully evaluates the tooth and recommends a plan based on the extent of decay, the child’s age and the long-term health of the tooth.

Frequently Asked Questions
Cavities can develop as soon as baby teeth erupt, though they are most commonly seen between ages two and five in the primary teeth and around ages six to twelve as the first permanent molars come in.
Most fillings are done using local anesthesia to numb the tooth so the child does not feel pain during treatment. Nitrous oxide may also be offered to help children stay relaxed, especially if they feel anxious. General anesthesia is only used in rare situations where a child cannot safely cooperate for treatment and is not the standard approach.
Daily oral care makes the biggest difference. This includes brushing twice a day with fluoride toothpaste, flossing once, limiting frequent sugary snacks and drinks and attending regular dental check-ups. Dental sealants on the back permanent molars can also help reduce the risk of future cavities.
Fillings in baby teeth usually last until the tooth naturally falls out, as long as oral care is maintained and hard or sticky foods are limited. Stainless steel crowns placed on primary molars are designed to stay in place until the tooth exfoliates and can last several years. Fillings in permanent teeth may eventually need replacement or repair over time.
Yes. If left untreated, decay in a baby tooth can spread to nearby teeth and may also affect the developing permanent tooth underneath. In some cases, this can lead to enamel defects or changes in how the adult tooth forms.
