Riverpark Dental London, ON

What is it

In a pulpectomy, the Dentist removes the pulp (the sensitive inner tissue) from the diseased tooth.

The pulpectomy procedure is commonly referred to a partial root canal. In a full root canal procedure, the initial steps are to remove the pulp and then to later remove other tissues. The pulpectomy procedure is commonly included in a child’s treatment plan.

The difference is when the tooth's canal(s) are filled, a material that can be reabsorbed by the body is most typically used because the primary teeth's roots are resorbed when the child’s adult teeth erupt.

When is it needed / Risks of not getting it done

A Dentist will advise the patient of a possible pulpectomy when the pulp is diseased to an extent that it cannot be treated with antibiotics.

The infected pulp results in an abscessed tooth (containing pus) and if left untreated can lead to facial, cranial, and cervical swelling. Bone infection and bone loss surrounding the tooth is likely to occur along with infection of adjacent bone and soft tissue.

A pulpectomy is most commonly used on diseased primary teeth of children because the procedure greatly reduces the risk of tooth loss. Jaw alignment complications occur when primary teeth are lost early.

How is it done

  1. First, the Dentist creates a small access whole on the tooth’s surface.
  2. Next, the Dentist removes the diseased nervous tissue, the infected pulp, and other decayed debris from the tooth's canal(s).
  3. Third, the tooth's canal(s) are sanitized with an antibacterial solution and then set up to receive the restorative material.
  4. Lastly, the pulp chamber of the tooth, the tooth's canal(s), and the surface access hole are filled and covered with a restorative material.
