Root Canal Treatment: What to Expect Step by Step

Root canal treatment is one of the most feared dental procedures — yet most patients who have had one tell us it was far easier than they expected. Modern RCT with advanced anaesthesia, digital imaging, and rotary instruments is routinely described as no more uncomfortable than getting a filling.

Why Root Canal Treatment Is Needed

Inside every tooth is soft tissue called the pulp, containing nerves and blood vessels. When decay reaches the pulp or the tooth is severely cracked, bacteria infect this tissue causing intense pain, swelling, and eventually an abscess if left untreated. Root canal treatment removes the infected pulp, cleans and seals the root canals, and preserves the outer shell of the tooth.

Step 1: Diagnosis and 3D Imaging

Digital X-rays and, for complex cases, a CBCT 3D scan show exactly how many root canals the tooth has, the degree of infection, and the precise anatomy we are working with.

Step 2: Local Anaesthesia

At Dr. Sri Sushma Multispeciality Dental Clinic we use advanced anaesthesia techniques to ensure the tooth is completely numb. You should feel pressure and movement, but no pain.

Step 3: Rubber Dam Placement

A thin rubber sheet around the tooth keeps it clean, dry, and protected from contamination by saliva during treatment.

Step 4: Access and Pulp Removal

A small opening is made in the top of the tooth. We use motorised nickel-titanium rotary instruments to gently remove infected pulp from each canal — faster, gentler, and more precise than traditional hand-only technique.

Step 5: Canal Shaping and Irrigation

Each canal is progressively shaped and irrigated with antimicrobial solutions (sodium hypochlorite and EDTA) to kill bacteria and dissolve organic debris. This irrigation phase is critical for long-term success.

Step 6: Filling and Sealing

The cleaned canals are filled with gutta-percha and sealed with dental cement permanently to prevent bacterial re-entry.

Step 7: Crown Placement

After root canal treatment, back teeth (molars, premolars) require a dental crown to restore full strength and prevent fracture. Usually placed at a separate appointment 1–2 weeks later.

How Long Does It Take?

Most routine single-sitting root canals take 45–90 minutes. Complex or severely infected teeth may require a second appointment.

After Treatment

Mild soreness for 2–4 days is normal. Avoid chewing on the treated tooth until the crown is placed. Resume normal brushing and flossing the same day.
