What is Pulpectomy Procedure and Why It is Necessary?

Pulpectomy is the minor surgical procedure performed on the primary tooth. It attempts to save the tooth and avoid extraction. The infectious or damaged pulp is the painful condition which requires immediate attention. Pulpectomy acts as a savior in such a situation. Pulp issues mainly arise due to extensive dental caries, tooth trauma, abscess, etc. We can not save the damaged pulp, but we can save the tooth by eliminating the diseased pulp.

What is pulpectomy?

Pulpectomy is the pulp therapy performed on the primary teeth. The vitality of the tooth is due to the presence of pulp inside it.

The pulp is covered by the outer thick tooth coating such as dentine and enamel and transmits the pain sensation of a tooth to the brain.

When the external hard tooth coatings of the tooth get damage due to crack or decay, dental pulp gets exposed and transmits the pain.

To restore tooth in such situation dentist undergo pulpectomy which is surgical removal of infected or necrosed pulp (2). Once the diseased pulp removed from the canal, pain automatically goes away.

Pulpectomy preserves the functionality of the tooth on the cost of its vitality. Saving the primary tooth is essential as it helps the kid in chewing, eating, speaking and also preserves the space for permanent teeth.

Early removal of the primary teeth leads to the development of crowding in the permanent dentition. Hence, the efforts are made to save the primary teeth.

  • Pedodontist clinically assesses the tooth and then takes the x-ray of the infected tooth. X-ray of the tooth gives the complete idea about the periapical infection, an extension of cavitation, etc.
  • The dentist now makes the kid sit in relax position and administer the local anesthesia to avoid pain during the procedure. Also, the rubber dam is then placed to achieve the isolation of the tooth.
  • Later on, the hole is made in the infected tooth to reach the canal. Once the canal located, the dentist removes the diseased pulp with the help of instruments. After the pulp removal, the canal is thoroughly irrigated with the irrigants to make the canal sterile and to avoid a further chance of infection.
