Pulpotomy vs. Pulpectomy: Two Different Ways to Treat a Child's Tooth

The pulp is the soft tissue inside a tooth, containing nerves and blood vessels, located both in the crown portion (the visible part above the gum) and extending down into the root canals beneath it.

A pulpotomy removes only the inflamed or infected pulp tissue in the crown portion of the tooth, leaving the healthy pulp tissue in the root canals intact and undisturbed, then sealing the remaining area with a protective material.

A pulpectomy removes the entire pulp, including the tissue extending into the root canals, similar in concept to an adult root canal, used when infection or damage has progressed beyond just the crown portion of the pulp.

Both procedures are frequently used to treat primary (baby) teeth affected by deep decay reaching the pulp, since preserving a baby tooth until it naturally falls out matters for proper spacing and guidance of the permanent tooth developing underneath it, rather than simply extracting a damaged baby tooth prematurely.

A pulpotomy is generally appropriate when the infection or inflammation is limited to the crown portion of the pulp, with the deeper root canal pulp remaining healthy, which a dentist determines through examination and imaging before proceeding.

A pulpectomy becomes necessary when infection or inflammation has progressed to affect the pulp tissue within the root canals themselves, not just the crown portion, requiring the more complete removal a pulpectomy provides to fully address the problem.

A pulpotomy is occasionally used as an emergency or interim treatment in a permanent tooth, particularly in specific situations like a young permanent tooth with incompletely formed roots, though a full root canal, similar in scope to a pulpectomy, is the standard, complete treatment for a mature permanent tooth with pulp infection.

Both procedures are performed under local anesthesia, with the dentist accessing the pulp chamber, removing the relevant portion of affected tissue, and then filling and sealing the remaining space with an appropriate material, followed generally by a crown, particularly common for baby molars treated this way, to protect the remaining tooth structure.

Most children tolerate these procedures well, with any discomfort typically manageable with over-the-counter children's pain relief as recommended by the dentist, and normal eating and activity generally resuming within a day or so.

While extraction is sometimes the necessary choice for severely damaged baby teeth, preserving a baby tooth through a pulpotomy or pulpectomy when reasonably possible helps maintain proper spacing in the jaw, guiding the permanent tooth to erupt in its intended position, since premature loss of a baby tooth can sometimes lead to crowding or spacing issues later.

This is determined through a clinical exam and X-rays, assessing how deeply the infection or inflammation has progressed within the tooth's pulp, guiding whether a pulpotomy's more conservative approach is sufficient or whether a pulpectomy's more complete removal is needed.
