Canal therapy, also known as root canal treatment, is a dental procedure used to treat infected or damaged teeth. The therapy involves removing the damaged or infected pulp, cleaning and disinfecting the inside of the tooth, and then filling and sealing it. This procedure is often necessary when the tooth’s pulp becomes infected or damaged, which can cause severe pain and potentially lead to an abscess if left untreated.

In children, canal therapy is typically only recommended when the tooth is severely damaged or infected and cannot be saved with a filling or other less invasive treatments. The treatment is performed under local anesthesia and is generally considered safe and effective in children when performed by an experienced dentist.

Why is Canal Therapy Needed in Children?

There are several reasons why a child may need canal therapy, including:

  • Severe tooth decay
  • A deep cavity or large filling that has damaged the tooth’s pulp
  • A fracture or crack in the tooth that has reached the pulp
  • Injury to the tooth, such as a traumatic blow, that has damaged the pulp

In some cases, a child may need canal therapy to treat a baby tooth that has become infected. While baby teeth eventually fall out, it is important to treat them to prevent the infection from spreading and causing harm to the permanent teeth that are developing under the gums.

Options for Canal Therapy in Children

There are several options available for canal therapy in children, including:

  • Conventional Canal Therapy: This is the most common type of canal therapy and involves removing the damaged or infected pulp, cleaning and disinfecting the inside of the tooth, and then filling and sealing it with a material such as gutta-percha.
  • Pediatric Canal Therapy: This type of canal therapy is designed specifically for children and may be performed using a smaller instrument and a less invasive technique. The goal of pediatric canal therapy is to preserve as much healthy tooth structure as possible and minimize discomfort for the child during and after the procedure.
  • Stainless Steel Crowns: In some cases, a child may need a crown (a cap that covers the entire tooth) after canal therapy. Stainless steel crowns are a common choice for children’s teeth because they are strong and durable, and they can be placed quickly and easily in a single visit to the dentist.

Preparing for Canal Therapy in Children

Before a canal therapy procedure, the dentist will examine the child’s tooth and take X-rays to determine the extent of the damage or infection. The will also discuss the procedure with the child and the parents, and answer any questions they may have. It is important to make sure that the child understands what will happen during the procedure and feels as comfortable as possible.

In some cases, the dentist may prescribe antibiotics to help prevent infection before the procedure. It is important to follow the dentist’s instructions and to give the antibiotics as directed.

Recovery After Canal Therapy in Children

After a canal therapy procedure, the child may experience some discomfort, swelling, or sensitivity. Over-the-counter pain relievers, such as ibuprofen, can help manage these symptoms. The dentist may also prescribe a stronger pain reliever if needed.

It is important to follow the dentist’s instructions for post-operative care, which may include avoiding hard or sticky foods for a few days, using a special mouthwash, and avoiding biting or chewing on the treated tooth until the crown is placed (if one is needed).

Most children are able to return to school or other activities the day after a canal therapy procedure. The treated tooth may be sensitive for a few days, but the discomfort should gradually subside as the tooth heals.


Canal therapy is an effective and safe treatment option for children with infected or damaged teeth. With proper care and follow-up, the treated tooth can last a lifetime and help to maintain a healthy smile.

If you are concerned about a possible infection or damage to your child’s tooth, it is important to see a dentist as soon as possible. Early treatment can help to prevent the need for more extensive and invasive procedures in the future.
