Nerve and Pulp Treatment

Nerve and Pulp Treatment for Children in San Marcos, CA

When a cavity or injury reaches the nerve inside a tooth, pulp therapy can relieve pain, control infection, and save the tooth. The two main pediatric options are a pulpotomy (treating part of the pulp) and a pulpectomy, sometimes called a baby root canal (treating the full pulp). At San Marcos Kids Dentistry, we choose the gentlest option that protects the tooth. Call (760) 744-8600.

Cavities and dental injuries can sometimes reach the inside of a tooth, where the nerve and blood supply live. When that happens, a child may have discomfort, sensitivity, or signs of infection. At San Marcos Kids Dentistry, we provide gentle pulp therapy to relieve pain, control infection, and protect your child’s tooth so it can keep doing its job. This page gives the big picture; for the most common single procedure, see our dedicated pulpotomy page.

What Is Dental Pulp?

Dental pulp is the soft tissue at the center of each tooth. It contains nerves, blood vessels, and connective tissue, and it helps nourish the tooth and support development and sensation. In children, pulp health matters especially because young teeth, and the permanent teeth forming beneath them, are still developing. Decay, poor oral hygiene, or trauma can damage the pulp and raise the risk of infection.

Signs Your Child May Need Pulp Treatment

When the pulp becomes inflamed or infected, you may notice:

• Persistent or unexplained tooth pain
• Pain that gets worse at night
• Sensitivity to hot or cold foods and drinks
• Swelling near the affected tooth

If your child has any of these, seek dental care promptly. Early treatment protects the tooth and reduces discomfort.

The Two Main Types of Pulp Therapy

Pulp therapy is used when the pulp is damaged but the tooth can still be saved. Which approach we recommend depends on how far the problem has spread.

Pulpotomy (Partial Pulp Treatment)

A pulpotomy treats the affected upper (coronal) portion of the pulp while preserving the healthy pulp in the roots. It is one of the most common pediatric procedures, often used when decay reaches the nerve but the root pulp is still healthy. A crown usually finishes the tooth. Read the full details on our pulpotomy page.

Pulpectomy (Full Pulp Treatment, or “Baby Root Canal”)

When infection has spread through the entire pulp, including the roots, a pulpectomy removes all of the diseased pulp from the crown and the root canals. The space is then cleaned and filled with a special resorbable material that the body can absorb naturally as the baby tooth’s roots dissolve and the permanent tooth comes in. A crown typically protects the tooth afterward. A pulpectomy lets us save a tooth that might otherwise need extraction, preserving space and function.

Why Saving the Tooth Matters

Keeping a baby tooth in place, when it can be safely saved, protects your child’s ability to chew and speak and holds space for the permanent tooth. Pulp therapy can be effective for both baby teeth and young permanent teeth, helping your child maintain a healthy bite and comfortable function. When a tooth cannot be saved, we will discuss gentle extraction and space management instead.

Keeping Treatment Comfortable

We numb the tooth first and use gentle, kid-focused techniques throughout. For children who feel anxious or need extra support, we offer sedation options and draw on proven behavior guidance. Most children tolerate pulp therapy very well.
