Frequently asked questions about root canal treatment:
Is root canal treatment painful?
We will always ensure that you are fully numb for this procedure and can always increase the level of numbness through the procedure in order for you to have a comfortable experience.
How long will it take to perform a root canal treatment?
The treatment time depends on the number of canals and complexity of the tooth receiving this treatment and generally takes about one to two hours.
What is the success rate of a root canal treatment?
Based on many studies if root canal treatment is performed by a skilled clinician the success rate is about 90-95%.
How many visits are required to perform the root canal treatment?
At Trusted Dental we perform most of our root canal treatments in a single visit however based on the complexity of the treatment or the state of each individual tooth multiple visits may be required.
Will I have pain after the endodontic treatment?
Some discomfort can be present following a root canal treatment which normally goes away within a few days. This can vary depending on the immune system of each person and the amount of infection in the tooth. If discomfort is present it can normally be controlled using over-the-counter painkillers. Your dentist will explain this to you in detail.
How much does root canal treatment cost?
The cost of the treatment depends on the number of canals treated and the complexity of the treatment and generally ranges from $800 for a single canal tooth to $1500 for a tooth with four or more canals.
At Trusted Dental we will provide you with an accurate treatment plan prior to start of the root canal treatment. After the treatment the tooth needs to be restored and your dentist will also discuss the cost of restoration and options available prior to start of your treatment.
What is a rubber dam and why should it be applied to the tooth during the treatment?
The success of a root canal treatment heavily relies on keeping the tooth as isolated as possible so that no new bacteria (i.e. from saliva) enters the canal.
A rubber dam is a piece of rubber sheet that significantly helps with isolating the tooth from oral environment and saliva and at the same time protects you.
What is the optimum restoration for the tooth which has received a root canal treatment?
This depends on the amount of structure lost and the status of the tooth receiving the treatment. A dental crown is a very good option to restore teeth which have lost most of their structure however in many instances a simple direct resin (tooth coloured) restoration will be sufficient.
What is a root canal retreatment? (Endodontic retreatment)
An endodontic retreatment is performed when a tooth with previous endodontic treatment becomes symptomatic or shows signs of root canal failure and infection. The main reasons that a tooth may not respond to previous root canal treatment are:
- Inadequate cleaning of the canals
- Inadequate restoration or failed restoration (i.e. cracked filling) which can lead to leakage of saliva and bacteria to the sealed canals leading to failure
- Missed canals in the tooth that did not receive treatment
- New decay starting that can lead to leakage of bacteria to the canals system
Generally, the treatment is similar to a normal root canal treatment with some modifications and unique approaches based on each individual tooth situation and happens through two or more visits.
What is a dental microscope and how does it help during endodontic treatment?
A dental microscope is a device that helps magnify the tooth and will significantly help the clinician to see fine details and small areas in the root canal system which ensures nothing is missed.
One of the main success factors of the root canal treatment is the ability to see all the anatomy and inspect the root canal system inside the tooth which at times can be a very complex structure.
While normal dental loupes (magnifying glasses worn by most of the dentists) provide some magnification typically about 2.5 – 6 times, a dental microscope takes this to the next level providing magnification levels of more than 30 times.
The role of microscope is even more significant in endodontic treatment of more challenging teeth such as multi rooted molars and canals with blockage or diagnosis of cracks.
At Trusted Dental we utilise a dental microscope for our root canal treatments to make sure you receive the highest standard of treatment.
