What is Root Canal & How is it Performed? 5 Symptoms You Should Know

If you’ve ever had a sudden sharp toothache while eating or a lingering sensitivity that just doesn’t go away, you might have heard the term root canal, often with a bit of fear attached to it.

What is the Root Canal?

A root canal treatment (RCT) is a procedure used to remove infection from inside the tooth and save the natural tooth instead of removing it.

Inside every tooth is a soft tissue called pulp. When this gets infected due to deep decay, cracks, or injury, it can cause pain and swelling. Root canal treatment in India and globally works by cleaning out this infection, disinfecting the area, and sealing the tooth to prevent further damage. 

In clinical experience, many patients walk in thinking the tooth will have to be removed. But in most cases, with timely care, the tooth can be preserved comfortably.

When Do You Actually Need a Root Canal?

Root canal treatment becomes necessary when the inner part of the tooth gets infected or inflamed.

Common causes include:

  • Deep cavities reaching the pulp
  • Cracked or chipped teeth
  • Repeated dental work on the same tooth
  • Infection spreading to the root

Many patients ignore early signs, assuming the pain will pass. In reality, delaying treatment often makes the condition more complicated.

5 Symptoms You Should Not Ignore

If you notice these signs, it’s worth getting your tooth checked early:

 

Symptom 

What it may indicate

Persistent tooth pain 

Deep infection or nerve involvement 

Sensitivity to hot/cold 

Nerve irritation 

Swollen or tender gums 

Infection near the root

Darkening of the tooth 

Internal damage

Pain while chewing 

Pressure on infected tooth

 

Even one or two of these symptoms can be enough to require evaluation. 

How Does Root Canal Treatment Work?

Many patients are curious about how a root canal actually works and what happens during the treatment. 

In simple terms, the procedure:

  • Removes the infected tissue from inside the tooth
  • Cleans and disinfects the root canals
  • Seals the tooth to prevent reinfection

The aim is not just to relieve pain, but to restore the tooth so it can function normally again. 

How is Root Canal Performed? (Step-by-Step)

Understanding how the root canal is performed helps reduce anxiety around the procedure. Here are the typical root canal procedure steps:

  1. Diagnosis and X-ray – to assess the infection
  2. Local anesthesia – to ensure comfort
  3. Cleaning the infected pulp
  4. Shaping and disinfecting the canals
  5. Filling and sealing the tooth
  6. Crown placement – to protect and strengthen the tooth

Is Root Canal Painful? (What Patients Usually Experience)

One of the most common concerns is: is the root canal painful?

The answer is no. Root canal treatment is designed to relieve pain and not cause it.

With modern anesthesia and improved techniques, the procedure usually feels similar to getting a regular filling. In fact, patients who come in with severe tooth pain often feel significant relief after treatment.

Why is a Crown Important After a Root Canal & How Long Does the Treatment Take?

After a root canal, the tooth becomes weaker and needs protection. A crown helps restore its strength so you can chew normally without risk of damage.

In general, how long root canal treatment takes depends on:

  • Severity of the infection
  • Condition of the tooth
  • Timeline for crown placement

Traditionally, patients had to wait 2–3 days for a customized crown, which meant multiple visits. Today, with advanced systems, Single visit crowns are possible.

At Dr. Ashwadhi’s clinic, customized crowns are prepared in about 2 hours, helping patients return to normal function much faster and with fewer visits. 

What Happens If You Delay Root Canal Treatment?

Delaying root canal treatment may seem harmless initially, but it can lead to: 

  • Increased pain
  • Spread of infection
  • Swelling or abscess formation
  • In some cases, loss of the tooth

Early treatment is always simpler, more comfortable, and more predictable.

What to Expect During and After Treatment

During treatment:

  • The procedure is done under anesthesia
  • You remain comfortable throughout

After treatment:

  • Mild sensitivity for a few days is normal
  • Chewing function gradually returns
  • Crown restores full strength

With proper care, a treated tooth can last for many years.
