Gentle, Effective Care for Infected Teeth at Ontario Children’s Dentist
When tooth pain, deep decay, or infection affects your child’s smile, pediatric root canal treatment can save the tooth and relieve discomfort quickly. At Ontario Children’s Dentist in Ontario, CA, we specialize in providing gentle, compassionate care for children who need root canal therapy—also known as pulpotomy or pulpectomy, depending on the severity of the infection.
Although the words “root canal” may sound intimidating, pediatric root canal treatments are far less invasive than the adult version and are performed with a high focus on comfort. Our experienced pediatric team ensures your child receives the safest, most effective care to protect their oral health and restore their smile.
What Is a Pediatric Root Canal?
A pediatric root canal is a procedure used to treat infection or inflammation inside a baby tooth or a newly erupted permanent tooth. When decay spreads deep into the nerve (pulp) of the tooth, your child may experience pain, swelling, or sensitivity. If left untreated, the infection can spread further, leading to more serious dental and health concerns.
Root canal treatment allows us to:
- Remove the infected portion of the pulp
- Clean and protect the inside of the tooth
- Strengthen the tooth with a crown when needed
- Preserve the tooth until it naturally falls out
Because baby teeth guide permanent teeth into position, saving them when possible is extremely important for your child’s long-term oral development.
Signs Your Child May Need a Root Canal
It’s not always easy to tell when a dental infection is developing. However, some symptoms should never be ignored. Contact Ontario Children’s Dentist right away if your child experiences:
- Persistent toothache or spontaneous pain
- Sensitivity to hot or cold foods
- Soreness while chewing
- Swelling or redness of the gums
- A darkened or discolored tooth
- Facial swelling
- A pimple-like bump on the gum (abscess)
Our pediatric dentist will perform a thorough exam and take digital X-rays to determine whether pulpotomy, pulpectomy, or another treatment is needed.

Types of Pediatric Root Canal Treatments
There are two main types of root canal treatments for baby teeth. Your child’s condition determines which approach is best.
1. Pulpotomy (Partial Nerve Treatment)
A pulpotomy is the most common root canal treatment for primary teeth. It involves removing only the infected portion of the pulp inside the crown of the tooth while preserving the healthy roots below. After cleaning, a medicated material is placed inside the tooth to soothe and protect it. The tooth is then restored with a dental crown for strength and stability.
2. Pulpectomy (Full Nerve Treatment)
A pulpectomy is recommended when infection extends into the roots of the tooth. In this treatment, the entire pulp tissue is removed from both the crown and roots, and the root canals are cleaned and filled with a child-safe, resorbable material. The tooth is then sealed with a crown to restore full functionality.
Both procedures are designed to relieve pain, eliminate infection, and help your child maintain a healthy smile.
Our Gentle, Kid-Friendly Approach to Root Canal Therapy
At Ontario Children’s Dentist, we understand that children—and parents—may feel nervous about root canal treatment. That’s why we use a comforting and patient-centered approach throughout the entire process.
Thorough Evaluation
We use low-radiation digital X-rays and a careful clinical exam to assess the tooth and determine the best treatment.
Comfort Comes First
Our pediatric team uses gentle numbing techniques, age-appropriate explanations, and positive reinforcement to help your child feel safe. For children experiencing anxiety or sensitivity, we offer nitrous oxide (laughing gas) to help them stay relaxed.
Removing Infection
We carefully remove the infected tissue while ensuring your child remains comfortable throughout the procedure.
Restoring the Tooth
Once the tooth is treated, we restore it—usually with a stainless steel or zirconia crown—to protect it from future damage.
Healthy, Pain-Free Results
Your child leaves with a stronger tooth, relief from discomfort, and improved oral health.
Our goal is to make treatment not only effective but also a positive experience that encourages lifelong trust in dental care.

Why Saving Baby Teeth Matters
Some parents wonder why a baby tooth would require a root canal if it’s eventually going to fall out. However, baby teeth play important roles, including:
- Maintaining space for permanent teeth
- Helping with chewing and proper nutrition
- Supporting clear speech development
- Preventing shifting or crowding of teeth
- Protecting overall jaw growth
Premature loss of baby teeth can lead to orthodontic problems, bite issues, and difficulty eating. A pediatric root canal helps protect your child’s future smile.
Aftercare Instructions: What to Expect
After a root canal, your child may experience mild soreness for a day or two. This can typically be managed with children’s over-the-counter pain relief. We also recommend:
- Avoiding sticky or hard foods for a few days
- Maintaining regular brushing and flossing
- Returning for follow-up visits and scheduled cleanings
- Contacting us if swelling or pain returns
Most treated teeth function normally and last until the baby tooth naturally exfoliates.
Preventing Future Infections
Good oral hygiene and regular dental visits can reduce the need for root canals. To help protect your child’s teeth:
- Brush twice daily with fluoride toothpaste
- Floss daily
- Limit sugary snacks and drinks
- Schedule routine dental checkups
- Ask about fluoride treatments and sealants
We work with families to create habits that support healthy smiles year-round.
