Root Canal Treatment
What is Root Canal Treatment?
Root canal treatment (RCT) is a dental procedure used to treat infection in the centre of the tooth, which houses the tooth's nerve. Infection in this area can be caused by deep decay, a large filling, or trauma such as a fall. When the nerve tissue becomes infected or dies, it can cause extreme sensitivity, toothache, pain when biting, and, in severe cases, dental abscesses. The alternative to RCT is typically tooth extraction.
During RCT, the infected or dying nerve tissue is removed, and the root canals are filled to prevent bacteria from re-entering. This helps save the tooth and restore its function.
What Can I Expect When Having a Root Canal?
Root canal treatment is a delicate procedure that may take more than one visit, depending on the severity of the infection. Here's what you can expect during the process:
-
Anaesthesia: Local anaesthetic is applied to ensure you are comfortable and pain-free during the procedure.
-
Removal of Decay: The dentist will carefully drill to remove the decayed tissue and access the infection.
-
Cleaning the Nerve Space: The infected nerve tissue is cleaned out, and the area is rinsed with disinfectants to eliminate any bacteria.
-
Filling the Root Canals: Once the area is clean, the root canals are filled with a biocompatible material to seal the space and prevent further infection.
-
Filling the Tooth: A conventional filling is placed over the tooth to restore its shape and function.
In some cases, you may need to return for a follow-up appointment to complete the procedure and place a permanent filling or crown.
Common Misconceptions About Root Canal Treatment
1. Root Canal Treatment is Painful
Many people associate RCT with pain because they experience toothache before the treatment due to the infection. However, once the local anaesthetic is applied, RCT should not be painful. The only discomfort you may experience is some post-operative soreness for a few days after treatment.
2. Root Canal Treatment Doesn’t Work
In most cases, 90% of teeth that undergo straightforward RCT remain healthy for 10 years or more. However, in cases where the tooth is severely decayed or very infected, the success rate may decrease. Your dentist will discuss the specific risks with you beforehand.
3. Root Canals Cause Cancer or Other Diseases
There is no scientific evidence linking root canal treatment to cancer or any systemic diseases. Root canal treatment is a safe and effective way to treat infected teeth and prevent further complications.
Is root canal treatment painful?
Most patients experience minimal discomfort during RCT due to the local anaesthetic. Some soreness after the procedure is normal but usually resolves within a few days.
How many visits does root canal treatment require?
Depending on the severity of the infection, RCT may require one or two appointments to complete the procedure.
Can I avoid root canal treatment?
If an infection is caught early, root canal treatment can often be avoided with timely intervention and proper oral care. However, if left untreated, the infection may lead to severe pain or the need for extraction.
How long does a root canal last?
A root canal can last many years with proper care.
Will I need a crown after root canal treatment?
In many cases, a crown is recommended after RCT to protect and restore the strength of the tooth. Your dentist will discuss whether a crown is necessary for your tooth.
