Thanks to the use of local anaesthetics, we are able to completely numb up the nerves responsible for pain in the area, so you will not feel a thing during treatment. However, when inflammation occurs certain “touch” nerves can elicit pain responses. Unfortunately, these do not numb up as successfully meaning some additional injections may be required, and discomfort may still be partially felt. This usually only occurs in very painful or “hot” teeth where the infection is extreme. This will usually only be the first visit if you presented with a tooth-ache, otherwise you are unlikely to feel anything at all. When you return for the next phase the anaesthetic should work with full proficiency. In fact, you may even fall asleep during the remaining parts of your procedure. This is another reason to state the importance of addressing teeth requiring root canal treatment sooner rather than later.
Like any medical procedure, a root canal treatment poses some risk and, on rare occasions, there may be complications. These complications may result in a tooth needing additional treatment, referral to a specialist or may result in the tooth needing to be removed. However, in most cases root canal treatment is very successful.
