Step One: Getting your tooth numb and placing a rubber dam.
Numbing your tooth with local anaesthetic will ensure your treatment is pain free. A rubber dam is then placed over your tooth, think of this as an anorak that sits over your tooth. This is particularly important in root canal treatment as it gives us a sterile environment to work in, preventing bacterial leakage into the tooth from your saliva and protects your airway from the fine instrument’s used in your treatment.
Step Two: Remove any old fillings
This allows us to remove any decay and examine how much remaining tooth structure you may have; it may allow us to rebuild the tooth before root canal therapy. If you have a crown, the crown will be removed before placement of the rubber dam, this allows us to see how much tooth structure you have left. If you don’t have a great deal of tooth left, then unfortunately root canal would not be justified as a definitive filling and new crown cannot be made.
Step Three: Cleaning the root canal
This stage is like a deep filling. We access the root canal system, locate the number of roots and begin to disinfect the root canals with antibacterial solutions.
Step Four: Filling the root canals
If all the roots have been located and disinfected, then we fill the root canals with a specific filling. This stage may require a new radiograph to check that all the canals have been cleaned and that we are filling the canals to the right areas.
Step Five: New filling/ Construction of a temporary crown.
In this stage we have finished the root treatment and we are placing a filling on the tooth this prevents any bacteria re-entering the root canal system from the oral cavity. If we removed the crown prior to the treatment at this stage a new temporary crow will be made for you chairside.
