Dental Fillings for Kids in Palo Alto

Our pediatric dental fillings in Palo Alto repair cavities and help restore and protect your child’s teeth.

Cavity Fillings for Kids

Children can develop cavities even when they have good oral hygiene and a healthy diet. To treat a cavity, our pediatric dentist may recommend a dental filling. The filling replaces the portion of the tooth affected by decay, helping prevent further damage while allowing the tooth to function normally.


Our approach to pediatric cavity treatment in Palo Alto considers your child's age, comfort level, dental development, and the size and location of the cavity. Depending on your child's needs, treatment may include a tooth-colored filling, glass ionomer filling, or another appropriate option. Dental fillings may help:


  • Repair teeth affected by cavities and tooth decay.
  • Prevent existing decay from progressing further.
  • Restore normal tooth shape and function.
  • Treat cavities in primary or permanent teeth.
  • Preserve healthy tooth structure whenever possible.

Types of Dental Fillings for Children

There are several options for treating cavities in children. The right choice depends on the cavity, the affected tooth, and your child's individual needs.


White Fillings (Composites) - Tooth-colored fillings for children use composite resin that closely matches the natural tooth. They can restore cavities while maintaining a natural-looking appearance.


Glass Ionomer Fillings - Glass ionomer is a tooth-colored material containing fluoride. It may be recommended for certain cavities and fillings for primary teeth.


Silver Diamine Fluoride (SDF) - SDF can help slow or stop certain cavities without traditional drilling. It may be helpful for young children or those who have difficulty tolerating longer dental procedures.

Silver Diamine Fluoride (SDF) Application

SDF is an alternative cavity treatment for toddlers and children that can help manage tooth decay without requiring a traditional filling at that time. The application is quick and may be useful for young children, children who have difficulty tolerating longer procedures, or primary teeth that are approaching the time when they will naturally fall out.


One important consideration is that SDF permanently darkens the decayed portion of the tooth. While it can help stop cavity progression, it does not replace missing tooth structure in the way a traditional filling does. The tooth may therefore require additional restorative care later. When your child is ready for a traditional filling, our pediatric dentist can determine the appropriate next step. For selected patients, SDF provides an alternative to fillings in baby teeth that can help manage decay while potentially delaying more involved treatment. Book an appointment today to learn whether SDF may be an appropriate cavity treatment for your child.

What to Expect During Dental Filling

Many dental fillings for kids can be completed in an hour or less, while a simple filling may take about 20 minutes. Treatment time can vary depending on the cavity, number of fillings, and your child’s individual needs.

  • Process of Child's Cavity Filling

    1. Examination and X-rays - Our pediatric dentist will examine your child's tooth and may take an X-ray to determine the extent of the tooth decay.
    2. Preparing the Tooth - When needed, local anesthesia may be used to numb the treatment area and help keep your child comfortable during the cavity filling procedure for kids.
    3. Removing the Decay - The damaged or decayed portion of the tooth is carefully removed. Depending on the clinical situation, different dental technologies or techniques may be used.
    4. Placing the Filling - The tooth is cleaned and prepared before the selected filling material is placed. Certain materials are hardened using a specialized dental light.
    5. Checking the Bite - Finally, our pediatric dentist polishes the tooth and checks your child's bite to make sure the filling feels comfortable and functions properly.

    After the procedure, your child's tooth may feel slightly sensitive as the numbness wears off. Temporary sensitivity to pressure or temperature can occur following a dental filling.

  • Recovering After a Dental Filling

    Most children recover quickly following a pediatric dental filling. As the anesthetic wears off, your child's tooth or surrounding area may feel sensitive for a short period. Following the aftercare instructions provided by our pediatric dental team can help make recovery more comfortable.


    You can help your child by:


    • Having them chew on the opposite side initially
    • Gently brushing and flossing around the filling
    • Avoiding extremely hot or cold foods and beverages temporarily
    • Avoiding sticky or very hard foods when instructed
    • Monitoring the treated tooth for persistent sensitivity
    • Following any additional instructions provided by our pediatric dentist

    Contact our office if your child's bite feels uneven or if they experience significant or persistent pain or sensitivity. The filling may need to be examined or adjusted.

  • Pain Following a Dental Filling

    When the filling is completed, your child may experience mild discomfort around the treated area for several hours. The mouth may also remain numb after treatment, so your child should be careful not to accidentally bite their cheek, lip, or tongue while sensation is returning.


    Some temporary sensitivity can occur as the anesthetic wears off. Follow the pain-management instructions provided by our pediatric dentist and ask us before giving your child medication if you are uncertain about what is appropriate.


    Your child may also be advised to temporarily avoid acidic, sticky, extremely hot, or cold foods depending on the filling material and treatment performed. If discomfort becomes severe, continues longer than expected, or your child's bite feels different, contact our office.

  • How to Know if Your Child Needs a Dental Filling

    Routine dental checkups allow your child's pediatric dentist to identify cavities at an earlier stage. Treating tooth decay early may allow for a more conservative treatment than waiting until the cavity becomes larger or begins causing discomfort.


    Possible signs your child may need pediatric cavity treatment include:


    • Tooth sensitivity to hot or cold foods and drinks
    • Sensitivity when consuming sugary foods or beverages
    • Persistent discomfort or pain in a tooth
    • A visible hole or pit in the tooth
    • White, brown, or dark discoloration on the tooth
    • Pain or discomfort when chewing

    Some cavities do not cause obvious symptoms during their early stages. If you believe your child has a cavity, schedule an examination with our pediatric dentist. We can determine whether your child needs a dental filling or another appropriate form of treatment.

Frequently Asked Questions

  • Do cavities in baby teeth need fillings?

    Cavities in baby teeth may require treatment even though primary teeth eventually fall out. Baby teeth play important roles in chewing, speech development, and maintaining appropriate space for permanent teeth. Depending on the size and location of the cavity, cavity fillings in baby teeth or another treatment may be recommended to prevent decay from progressing.

  • How does a pediatric dentist fill a child's cavity?

    A child cavity filling typically begins with an examination and, when necessary, an X-ray to determine how far the decay has progressed. The treatment area may be numbed before the decayed portion of the tooth is removed. The tooth is then prepared and restored with an appropriate filling material before your child's bite is checked.

  • Can a toddler receive a dental filling?

    Yes, toddlers can receive dental fillings when treatment is necessary, although the recommended approach depends on the child's age, cavity, comfort level, and ability to cooperate during treatment. For some children, traditional toddler cavity filling treatment may be appropriate, while alternatives such as silver diamine fluoride may be considered in selected situations.

  • Are tooth-colored fillings safe for children?

    Composite resin is commonly used for tooth-colored fillings for children and can restore certain cavities while closely matching the appearance of natural teeth. The appropriate filling material depends on several factors, including the location and size of the cavity. Our pediatric dentist will discuss available materials and recommend an option based on your child's individual dental needs.

  • Can the Solea laser be used for children's cavity fillings?

    Solea may be used for certain laser fillings for children and other dental procedures when clinically appropriate. Depending on the tooth and treatment required, laser dentistry may reduce some of the sensations associated with traditional drilling. Not every cavity can be treated the same way, so our pediatric dentist will determine whether Solea is suitable for your child's specific cavity.
