Root Canal Treatment
What Is It?
Root canal treatment is a dental procedure used to treat infection or damage inside a tooth's pulp (the soft tissue inside the tooth that contains nerves and blood vessels).
The procedure involves:
-
Removing the infected or dead pulp
-
Cleaning and disinfecting the root canals
-
Filling and sealing the space
-
Restoring the tooth with a crown or filling

Why Is It Needed?
RCT is recommended when:
-
There's deep decay or cavity reaching the pulp
-
The tooth has repeated dental procedures
-
There is a crack or chip in the tooth
-
The pulp is inflamed, infected, or dead due to trauma or bacteria
Symptoms that may require RCT:
-
Persistent toothache
-
Sensitivity to hot/cold
-
Swelling or pus around the gum
-
Discoloration of the tooth
-
Pain when chewing or touching
How Is It Done? (Steps)
-
Diagnosis
-
X-ray to see the root canal shape and detect infection.
-
-
Local Anesthesia
-
Numbing the area to ensure a pain-free procedure.
-
-
Access Opening
-
A small hole is drilled in the tooth to reach the pulp.
-
-
Pulp Removal
-
Diseased pulp is removed with files.
-
-
Cleaning & Shaping
-
Root canals are cleaned, shaped, and disinfected.
-
-
Filling
-
Canals are filled with a rubber-like material (gutta-percha).
-
-
Sealing
-
Temporary or permanent filling placed to close the tooth.
-
-
Restoration
-
A crown is usually placed later to restore full function and strength.
-
Types of Root Canal Treatments
-
Conventional RCT
-
Standard method using hand or rotary instruments.
-
-
Single-Visit RCT
-
Completed in one sitting; suitable for cases without infection.
-
-
Multiple-Visit RCT
-
Used when infection is present; includes placing medicine (e.g., calcium hydroxide) between visits.
-
-
Retreatment RCT
-
Done when a previous root canal fails.
-
-
LASER assisted RCT - Laser is used to disinfect canals in addition to standard method of cleaning
-
Apicoectomy (Endodontic Surgery)
-
Surgical option if standard RCT fails; tip of the root is removed.
-
How Many Visits Are Needed?
-
Single Visit:
-
Suitable for uncomplicated cases with no swelling or pus.
-
-
Two or More Visits:
-
Used if there’s infection, abscess, or complex anatomy.
-
First visit: cleaning & medication
-
Second/third: filling, sealing, and crown placement
