What Is Root Canal Treatment?

Root canal treatment is a dental procedure performed when the nerve tissue inside a tooth becomes damaged or infected. It involves the removal of the soft tissue called the pulp from inside the tooth, followed by cleaning and filling of the root canals. This procedure is done to save the tooth and prevent further infections.

Purpose of Root Canal Treatment

Nerve tissue damaged by decay or trauma can lead to infection or pain in the tooth. In such cases, root canal treatment allows the tooth to continue functioning without the need for extraction. It also helps preserve the natural structure of the tooth for a longer period.

Stages of Root Canal Treatment

Diagnosis and X-Ray
In the first stage, the dentist examines the tooth and takes an X-ray to assess the extent of the damage. This helps determine the size of the infection and the condition of the root canals.

Anesthesia and Tooth Preparation
Before starting the treatment, local anesthesia is administered to ensure the patient feels no pain during the procedure. A small opening is then made in the top of the tooth to access the root canals.

Cleaning the Root Canals
The pulp tissue inside the tooth is carefully removed, and the canals are cleaned using special instruments. The canals are disinfected to prevent the spread of infection.

Filling the Root Canals
Once cleaned, the canals are filled with a biocompatible filling material. This seals the space, protecting the tooth and preventing future infections.

Sealing and Restoring the Tooth
The treated tooth is sealed with a filling or a crown to restore its natural function. In most cases, a crown is recommended after root canal treatment due to the tooth’s increased fragility.

Benefits of Root Canal Treatment

Preserves the natural tooth, eliminating the need for extraction.
Prevents the spread of infection, protecting surrounding teeth.
Restores chewing function and aesthetic appearance.
With proper care, a root canal-treated tooth can remain healthy for a lifetime.

Is Root Canal Treatment Painful?

No, root canal treatment is not painful because local anesthesia is used. You may feel mild sensitivity after the procedure, but this is temporary.

How Long Does Root Canal Treatment Take?

Root canal treatment for a single tooth typically takes 1–2 hours and is often completed in a single session. However, multiple sessions may be required in some cases.

How Long Does a Root Canal Last?

When performed correctly, a root canal can last a lifetime. However, regular dental check-ups are important to maintain the health of the treated tooth.

Can a Root Canal-Treated Tooth Get Infected Again?

Yes, reinfection is possible if the tooth is not properly cared for or if the filling material deteriorates over time.

What Should Be Considered After Treatment?

Since the treated tooth may be sensitive for a while, it is recommended to avoid hard foods during the healing period.

Does a Tooth Become Fragile After Root Canal Treatment?

Yes, a root canal-treated tooth becomes more fragile. Therefore, a crown is usually recommended to protect it.

Can Children Have Root Canal Treatment?

Yes, but it is generally not performed on baby teeth. It is typically done on permanent teeth.

Will the Tooth Change Color After a Root Canal?

In rare cases, the treated tooth may darken. If this happens, whitening or a dental crown may be considered.

What Happens If a Root Canal Is Not Performed?

If left untreated, the infection can spread and lead to tooth loss.
