Modern endodontic approaches have considerably increased the success rates of
root canal treatments – recurring inflammation in a tooth that has already been
treated for a root canal infection is becoming a very rare complication. Still, we do
need a backup plan for the few cases when it does occur.

Mostly, even in these cases, a second root canal treatment has a good chance of
permanently curing the infection. But there are specific conditions under which a
treatment revision is not promising, or simply not possible. Then, a root tip
resection – the surgical removal of the final part of the tooth’s root – is an
alternative treatment option.

Reasons for a root tip resection

A root tip resection is considered if the root area of a tooth that has already been
root canal treated shows signs of recurring infection that is also affecting the
surrounding jawbone.

  • If the tooth in question has been restored with a post crown (a
    crown that is anchored in a root canal via a metal pin) or if it is one
    of the abutment teeth of a multi-unit bridge, these expensive
    restorations would have to be sacrificed to approach the root canals
    for revision treatment. Removing the restorations also bears the risk
    of fracturing the tooth.
  • In cases of teeth with very complicated (strongly curved/angled)
    root canal anatomy (which would probably have been the reason for
    the failure of the first root canal treatment), your endodontist may
    rate the chances of a successful treatment revision too slim to really
    warrant the attempt.

In such cases, a root tip resection is typically the most promising and most efficient
treatment option to retain the tooth.

Minimally invasive root tip resection procedure at PlusEndo

At Plusendo, we use endodontic microsurgery to perform root tip resections with
minimal tissue damage and very favorable prognosis. During the procedure, which
is performed under our dental microscope, the root tip is removed through a small
incision, and the remaining root end is thoroughly cleaned using ultrasonic
instruments. Finally, a bacteria-proof seal is created using a bioceramic filling
material.

Scientific studies have proven these new materials and techniques to be vastly
superior to conventional root tip resection procedures: Even advanced

inflammations of the root area and jawbone now have a very good chance of
complete and long lasting resolution.
