Root canal treatment for gangrene
If the pulp is not only inflamed, but has already disintegrated due to the influence of bacteria, gangrene has developed. The treatment of gangrene is much more complex and lengthy than that of pulpitis. When the pulp chamber is opened, foul-smelling gases escape, but the patient feels immediate relief because the gases no longer press on the opening at the tip of the root.
After the decayed pulp is removed, the opening is widened and the tooth is left open or closed with a cotton ball so that the gases can escape but food remains cannot penetrate. In the next root canal treatment session, the root canal is widened and cleaned of debris. An X-ray shows how far the canal has been prepared.
After an antiseptic insert, the tooth is provisionally closed. If the tooth remains without symptoms for a longer period of time, the canal can be filled with gutta-percha or another root filling material and finally closed.

Summary
Root canal treatment is used for acutely inflamed pulp. It can be carried out in one session if the procedure is uncomplicated. In the case of gangrene, the treatment is longer and more complex.
Root canal treatment for milk teeth depends on the initial position, but it differs significantly from that for adults. Root apex resection removes the pus at the root tip and the tip itself.
