What Is a Root Canal Surgery?
What Is a Root Canal?
A root canal is a dental procedure used to treat infection or damage inside a tooth. Each tooth has a soft inner layer called the pulp, which contains nerves, blood vessels, and connective tissue. When this pulp becomes infected or inflamed, it can cause significant pain and lead to serious complications if left untreated.
A root canal removes the infected pulp, cleans the inside of the tooth, and seals it to prevent further infection.
Why Would You Need a Root Canal?
There are several reasons why a dentist may recommend a root canal.
Common causes include:
- Deep cavities (tooth decay)
- Cracked or chipped teeth
- Repeated dental procedures on the same tooth
- Trauma or injury to the tooth
- Untreated dental infections
When bacteria reach the pulp, they can cause infection that spreads and worsens over time.
Signs You May Need a Root Canal
Not all cases show obvious symptoms, but there are common warning signs you should not ignore.
These include:
- Severe tooth pain, especially when chewing
- Sensitivity to hot or cold that lingers
- Swollen or tender gums
- Darkening or discoloration of the tooth
- A pimple-like bump on the gums
- Persistent bad taste or odor
If you notice any of these symptoms, it’s important to see a dentist as soon as possible.
What Happens During a Root Canal Procedure?
Understanding the process can help reduce anxiety about the treatment.
Step 1: Examination and X-rays
Your dentist will examine the tooth and take X-rays to determine the extent of the infection.
Step 2: Local Anesthesia
The area around the tooth is numbed to ensure you feel little to no pain during the procedure.
Step 3: Removing the Infected Pulp
A small opening is made in the tooth, and the infected pulp is carefully removed.
Step 4: Cleaning and Disinfection
The inside of the tooth is cleaned, shaped, and disinfected to remove bacteria.
Step 5: Filling the Root Canal
The cleaned space is filled with a special material to seal the tooth.
Step 6: Restoration
In most cases, a crown is placed on the tooth to restore its strength and function.
Is a Root Canal Painful?
One of the biggest myths about root canals is that they are extremely painful.
In reality:
- The procedure is done under anesthesia
- Most patients feel little to no pain during treatment
- It often relieves the pain caused by the infection
After the procedure, mild soreness is normal but usually manageable with over-the-counter pain relief.
How Long Does the Procedure Take?
A root canal can typically be completed in one or two visits, depending on the complexity of the case.
Each session may last between 60 to 90 minutes.
Recovery and Aftercare
After your root canal, proper care is essential for healing and long-term success.
Tips for recovery:
- Avoid chewing on the treated tooth until fully restored
- Maintain good oral hygiene
- Take prescribed medications if needed
- Attend follow-up appointments
Most people can return to normal activities the same day.

A root canal is often the best option for saving your natural tooth.
Advantages include:

What Happens If You Don’t Get a Root Canal?

Risks include:
- Worsening infection
- Abscess formation
- Tooth loss
- Spread of infection to other areas
Delaying treatment can result in more complex and costly procedures.
Root Canal vs. Tooth Extraction
In some cases, extraction may be considered, but it’s usually a last resort.
Root canal advantages over extraction:
- Preserves your natural tooth
