What Is Pulp Therapy?
Every tooth has a soft tissue center called the dental pulp. The pulp contains nerves, blood vessels, and connective tissue that help the tooth grow and develop. In baby teeth, the pulp is proportionally larger than in adult teeth, which means decay can reach it more quickly.
When bacteria from a cavity penetrate deep enough to reach the pulp, the tissue becomes inflamed or infected. Without treatment, the infection can spread to the root, cause an abscess, damage the developing permanent tooth underneath, or lead to premature tooth loss. Pulp therapy removes the infected tissue while preserving as much of the natural tooth structure as possible.
Pulpotomy: Partial Pulp Removal
A pulpotomy is the more common of the two procedures. The pediatric dentist removes only the diseased pulp tissue from the crown (top portion) of the tooth, leaving the healthy pulp in the root canals intact. A medicated material is placed over the remaining pulp to promote healing and prevent further infection.
A pulpotomy is appropriate when the infection is limited to the crown pulp and the root pulp remains healthy. It is sometimes called a "baby tooth root canal," though it is less involved than a true root canal.
Pulpectomy: Complete Pulp Removal
A pulpectomy is needed when the infection has spread from the crown into the root canals. The dentist removes all the pulp tissue from both the crown and the roots of the tooth. The empty canals are cleaned, disinfected, and filled with a resorbable material that will dissolve naturally as the baby tooth root resorbs before the permanent tooth erupts.
A pulpectomy is essentially the baby tooth version of a root canal. It is a more extensive procedure than a pulpotomy but still preserves the outer shell of the tooth.
Why a Child Might Need Pulp Therapy
The most common reason for pulp therapy in children is deep tooth decay that has reached the pulp. However, other situations can also damage the pulp and require treatment.
Signs Your Child May Need Pulp Therapy
Watch for these symptoms, which may indicate the pulp of a baby tooth is inflamed or infected.
- Persistent toothache, especially pain that wakes a child at night
- Sensitivity to hot or cold food and drinks that lingers after the stimulus is removed
- Swelling or a pimple-like bump on the gum near the affected tooth
- Darkening or discoloration of the tooth
- Pain when chewing or biting
- Unexplained irritability or refusal to eat in younger children
What to Expect During Pulp Therapy
Pulp therapy is typically completed in a single appointment. The procedure is performed under local anesthesia, and your pediatric dentist may also use nitrous oxide (laughing gas) or other sedation options if your child is anxious or very young.
Step-by-Step Procedure
The dentist begins by numbing the area around the tooth with local anesthetic. A rubber dam (a small sheet that isolates the tooth) is placed to keep the area dry and prevent your child from swallowing any materials. The dentist then removes the decayed portion of the tooth to access the pulp chamber.
For a pulpotomy, the infected pulp in the crown is removed and a medicated dressing, often mineral trioxide aggregate (MTA) or ferric sulfate, is placed on the remaining healthy pulp. For a pulpectomy, the pulp from both the crown and root canals is removed, the canals are cleaned and shaped, and a resorbable filling material is placed in the canals.
After the pulp treatment is complete, the tooth is restored. In most cases, a stainless steel crown is placed over the tooth to provide full coverage and strength. The crown protects the weakened tooth structure until the baby tooth falls out on its own.
Sedation Options for Young Children
Many pediatric dentists offer sedation options to help children stay calm and comfortable during pulp therapy. Nitrous oxide (laughing gas) is the mildest option and wears off within minutes after the appointment. Oral sedation (a liquid medication taken before the appointment) provides a deeper level of relaxation. In some cases, general anesthesia in a hospital or surgery center setting may be recommended for very young children or those with extensive treatment needs.
Your pediatric dentist will discuss which sedation option is appropriate based on your child's age, temperament, and the extent of treatment needed.
Recovery and Aftercare
Most children recover quickly after pulp therapy. The numbness from local anesthesia typically wears off within 1 to 3 hours.
The First 24 Hours
Mild soreness around the treated tooth is normal and usually resolves within a day. Over-the-counter children's pain relievers such as ibuprofen or acetaminophen can manage any discomfort. Give your child soft foods for the rest of the day and encourage them to chew on the opposite side.
Watch your child carefully while their mouth is still numb. Children sometimes bite their lip, cheek, or tongue without realizing it. Keep them away from hot foods and drinks until full feeling returns.
Long-Term Care After Pulp Therapy
A tooth treated with pulp therapy and capped with a stainless steel crown typically functions normally until it falls out on its own when the permanent tooth is ready to come in. Continue regular brushing and flossing around the crowned tooth.
Attend all follow-up appointments. Your pediatric dentist will take periodic X-rays to make sure the treated tooth is healing properly and that the developing permanent tooth underneath is not affected. Contact your dentist if your child develops new pain, swelling, or a bump on the gum near the treated tooth.
Pulp Therapy Cost for Children
The cost of pulp therapy depends on the type of procedure, whether sedation is used, and the type of restoration placed afterward. Costs vary by location and provider.
Typical Cost Ranges
A pulpotomy for a baby tooth typically costs between $150 and $350 per tooth before insurance. A pulpectomy usually costs between $200 and $450 per tooth. A stainless steel crown, which is often placed after pulp therapy, adds approximately $150 to $350. If sedation is needed, costs can increase by $100 to $500 or more depending on the type of sedation used.
Insurance and Medicaid Coverage
Most dental insurance plans cover pulp therapy and stainless steel crowns for children as medically necessary procedures. Medicaid and CHIP programs in most states also cover these treatments. Coverage details, copays, and annual maximums vary by plan, so check with your insurance provider before the appointment to understand your out-of-pocket costs.
When to See a Pediatric Dentist
If your child has a toothache, visible decay, or any signs of infection in a baby tooth, schedule an appointment with a pediatric dentist as soon as possible. Early treatment can often save the tooth with a simpler pulpotomy rather than a more involved pulpectomy.
A pediatric dentist is the best choice for pulp therapy because they have specialized training in treating young children, managing behavior, and using child-appropriate sedation techniques. They also have experience determining whether a baby tooth can be saved or whether extraction is the better option.
When Extraction Is a Better Option
In some cases, pulp therapy is not the best choice. If the tooth is severely damaged, the infection is too extensive, or the permanent tooth is close to erupting, extraction may be recommended instead. If a baby tooth is removed early, a space maintainer may be placed to hold the space open for the permanent tooth. Your pediatric dentist will explain all options and help you make the best decision for your child.
Find a Pediatric Dentist Near You
A pediatric dentist completes 2 to 3 years of additional specialty training after dental school, with a focus on treating infants, children, and teens. They are trained in pulp therapy techniques, child sedation, behavior management, and the unique dental needs of growing children.
When selecting a pediatric dentist for pulp therapy, ask about their experience with pulpotomy and pulpectomy procedures, the materials they use, and what sedation options they offer. You can search for a board-certified pediatric dentist in your area using our provider directory.
