With the technological development dentistry has seen, results are getting better every year, and this is true of root canal fillings, which can now be achieved in one session only — in large part due to the dental microscope.
The microscope magnifies the canals up to 25 times their natural size, so the dentist can actually see what they are working on rather than working by feel.
That makes it possible to find every canal. Missed canals are one of the most common reasons a root canal fails and has to be redone.
It allows the canals to be cleaned far more thoroughly, which is what removes the infection and the pain.
It reduces the number of visits: what usually takes two or three sessions can often be finished in one.
And it makes the whole procedure more comfortable, because less time in the chair means less anaesthetic and less fatigue.
Before you have a nerve treated, ask the clinic whether they have one.
