The success of a root canal comes down largely to one main point- has the whole root system been sufficiently disinfected, appropriately filled and properly sealed? If the answer is 'yes', the root canal is very likely to be successful.
Any factor that influences achieving this outcome, will therefore effect the success of the root canal treatment:
- The dentist- Their experience, technique and the materials and equipment used.
- The tooth- There are many issues related to the tooth that influence the prognosis- here are some of the main ones:
How infected the canal(s) are initially. The more infected the root system, the poorer the prognosis as the percentages above suggest.
How much tooth remains may not affect the success of the root canal procedure
directly but it will affect how good the crown
is on top and therefore how long you have a useful tooth in your mouth.
How complex the root canal system is, how curved, how many and how accessible the canals are- these factors will all influence the difficulty of the treatment and the outcome.
Is it the first time it has been attempted or is it a re-root canal treatment
Is it a natural tooth you are going into, or through a crown, in which case orientating yourself can be more difficult.
