The Process of Root Canal Therapy
                     The Process of Root Canal 
Therapy
DIAGNOSIS 
AND
X-RAYS
The dentist administers local anesthesia to 
numb the affected tooth and the surrounding 
area. This ensures that the patient is 
comfortable and pain-free during the 
procedure.
LOCAL ANESTHESIA
The dentist examines the tooth and takes X-rays 
to assess the extent of the infection or damage. 
This helps in determining whether a root canal 
is necessary.
ISOLATION
The dentist places a rubber dam around the 
tooth to isolate it from saliva and maintain a 
clean and dry environment. This prevents 
contamination of the tooth during the 
procedure.
ACCESS 
AND 
CLEANING
The dentist creates a small opening in the 
crown of the tooth to access the pulp chamber 
and root canals. The infected or damaged pulp 
is removed using specialized instruments. The 
root canals are then cleaned, shaped, and 
disinfected to remove any debris or bacteria.
FILLING 
AND 
SEALING
After cleaning and shaping, the dentist fills the 
empty root canals with a biocompatible 
material called gutta-percha. This material 
seals the canals, preventing further infection 
and providing structural support to the tooth. 
The access opening is also sealed with a 
temporary or permanent filling.
RESTORATION
Depending on the extent of tooth structure lost, 
a crown may be recommended to protect the 
weakened tooth. A dental crown provides 
strength and functionality to the treated tooth, 
allowing it to function like a natural tooth.
