Worried that a root canal might hurt? Discover how modern technology makes root canal treatment virtually painless, what the process involves, and why Worldwide Dental Hospital in Vietnam is trusted by expats for comfortable, precise care.
UNDERSTANDING ROOT CANAL TREATMENT
A root canal (or endodontic treatment) is a dental procedure used to save a tooth that’s badly decayed or infected. Instead of extracting the tooth, your dentist removes the damaged pulp, disinfects the root canals, and seals them to prevent further infection.
This treatment helps relieve pain, preserve your natural tooth, and restore full chewing function.
At Worldwide Dental Hospital, root canal therapy is performed using rotary endodontic systems and digital imaging, ensuring safety, precision, and comfort.
DOES ROOT CANAL TREATMENT HURT?
The short answer is no — modern root canal treatment is not painful.
Thanks to advanced anesthesia, rotary instruments, and digital guidance, most patients describe the experience as being no more uncomfortable than getting a filling.
Why It Doesn’t Hurt
- Local anesthesia completely numbs the tooth and the surrounding area.
- Modern techniques minimize pressure, vibration, and noise.
- Infection — not the treatment — is what causes the pain in the first place.
Once the infected pulp is removed, the pain and inflammation subside almost immediately.
WHY ROOT CANALS USED TO HAVE A BAD REPUTATION
In the past, root canals were performed with outdated instruments and limited anesthesia.
Procedures took longer, and post-treatment discomfort was more common.
Today, with ultrasonic irrigation, rotary systems, and 3D imaging, root canal therapy at Worldwide Dental Hospital is fast, precise, and virtually pain-free.
STEP-BY-STEP GUIDE TO ROOT CANAL TREATMENT
Understanding what happens during a root canal can help ease anxiety.
Step 1: Consultation and X-Ray
Your dentist begins with a digital X-ray or 3D CBCT scan to assess the extent of decay and the shape of the root canals.
This ensures accurate diagnosis and treatment planning.
Step 2: Local Anesthesia
A local anesthetic is administered to numb the affected tooth and the surrounding area.
You’ll remain fully awake but feel no pain during the procedure.
Step 3: Isolation
A rubber dam is placed around the tooth to keep it dry and free from saliva.
Step 4: Cleaning and Shaping the Canals
The dentist makes a small opening in the tooth to remove the infected pulp using rotary endodontic instruments.
The canals are then cleaned, disinfected, and shaped for filling.
Step 5: Filling the Canals
The cleaned canals are filled with a biocompatible material called gutta-percha, which seals the space and prevents reinfection.
Step 6: Sealing the Tooth
A temporary or permanent filling is placed.
In most cases, a porcelain crown is added later to restore strength and appearance.
At Worldwide Dental Hospital, most root canal treatments are completed in 1–2 visits, depending on the tooth’s complexity.
WHAT TO EXPECT AFTER TREATMENT
After the anesthesia wears off, you might feel mild tenderness or sensitivity for a few days — but this is normal and temporary.
Common Post-Treatment Sensations
- Slight soreness when chewing.
- Sensitivity to pressure or hot/cold.
- Mild swelling (rare).
What You Can Do
- Take prescribed pain relievers or antibiotics if recommended.
- Eat soft foods for the first 24 hours.
- Avoid chewing on the treated tooth until the crown is placed.
At Worldwide Dental Hospital, every patient receives personalized aftercare instructions and a follow-up check to ensure full healing.
HOW LONG DOES A ROOT CANAL TAKE?
The duration depends on the number of canals and the severity of the infection.
| Tooth Type | Average Duration | Notes |
| Front Tooth (1 canal) | 30–45 minutes | Simple and quick. |
| Premolar (2 canals) | 45–60 minutes | Moderate complexity. |
| Molar (3–4 canals) | 60–90 minutes | More detailed cleaning required. |
Worldwide Dental Hospital uses rotary systems that make the process 40% faster and more precise than manual tools.
WHY YOU SHOULDN’T DELAY ROOT CANAL TREATMENT
Ignoring tooth pain or infection can cause serious complications.
Risks of Delaying Treatment
- Spread of infection to the surrounding bone or gums.
- Formation of abscesses.
- Increased swelling and pain.
- Higher risk of tooth loss.
A timely root canal not only stops pain but also prevents the need for more expensive procedures like implants or bridges.

IS IT BETTER TO EXTRACT THE TOOTH INSTEAD?
Extraction might seem easier, but keeping your natural tooth is almost always better.
Benefits of a Root Canal Over Extraction
- Preserves natural tooth structure.
- Prevents bone loss in the jaw.
- Avoids the shifting of neighboring teeth.
