Does Root Canal Hurt? Understanding Root Canal Pain

Root canal therapy has long been a source of uncertainty for many people. You may have heard stories from friends or family that left you wondering: Does root canal hurt?

This question is more common than you might think, and it’s completely valid to feel a bit nervous about any dental procedure, especially one that involves the deeper layers of the tooth.

Let’s explore the details of root canal therapy so you can feel empowered, informed, and confident about your oral health and future.

What Is Root Canal Therapy?

A root canal is a type of endodontic therapy designed to treat infection inside a tooth. The treatment becomes necessary when the dental pulp, the soft centre of your teeth made up of connective tissue, blood vessels, and nerves, becomes infected or inflamed.

The primary aim of the root canal procedure is to save the natural tooth while eliminating the infection and preventing it from spreading to the surrounding area.

Why Might You Need Root Canal Treatment?

You might need a root canal if your tooth pulp has become infected due to:

• Deep decay
• Cracks or chips in the tooth
• A loose tooth resulting from injury
• Repeated dental procedures on the same tooth
• Trauma that damages the soft tissue

If left untreated, the infected pulp tissue can lead to an abscess, which may cause throbbing pain, swelling, or even bone loss around the root.

Common Root Canal Symptoms

Knowing the signs early can help you seek treatment before symptoms worsen:

• Persistent pain when chewing or biting
• Sensitivity to cold food or hot drinks that lingers
• Swollen or tender gums
• A darker colour of the tooth
• A pimple-like bump on the gums
• Pain that disrupts sleep
• Discomfort when tapping the affected tooth

Not all symptoms are obvious, so regular check-ups are key to having good dental hygiene and identifying problems early.

Does Root Canal Hurt During The Procedure?

The short answer is not to a severe extent. Thanks to modern local anaesthesia and significant advancements in dental care, most people experience little discomfort during the procedure.

The area surrounding the impacted tooth is thoroughly numbed with a local anaesthetic. You might feel mild pain, similar to having a filling done, but you should not feel severe pain.

What Happens During A Root Canal Procedure?

A root canal procedure is a structured treatment designed to ease discomfort and preserve your natural tooth. While every case is unique, the process typically involves the following steps:

1. Diagnosis With X-rays

Your dentist will take detailed X-rays to evaluate the extent of the infection in the tooth and surrounding area, including the health of the dental pulp and any signs of deep decay or tooth damage.

2. Removing The Infected Pulp

After applying local anaesthetic, a small opening is made in the affected tooth to access and gently remove the infected pulp tissue using fine instruments, relieving pressure and the source of the root canal pain.

3. Cleaning And Disinfecting

After the damaged pulp has been removed, the inner part of the tooth is meticulously cleaned and disinfected. This step helps eliminate bacteria and reduces the risk of further complications or reinfection.

4. Filling The Canal

Once the tooth is clean and dry, the root canals are filled with a biocompatible material that helps stabilise the internal structure. This material supports the treated tooth and prevents bacteria from re-entering the space.

5. Restoring The Tooth

A dental crown is often placed over a tooth to protect its structure and restore full function. This helps reinforce the tooth, improve its appearance, and ensure long-term stability, especially for back teeth that experience heavier chewing forces.

 

 

How Long Does A Root Canal Take?

The duration depends on several factors, including the location of the tooth and the severity of the infection. Most root canal procedures can be completed in one or two appointments, with each session lasting anywhere from 60 to 90 minutes.

Does Root Canal Hurt After The Procedure?

You might feel mild discomfort but not severe pain. In fact, if you were dealing with an infected tooth before the procedure, you’ll likely feel better once the source of the pain is removed.

Any lingering painful sensations typically subside within a week. If discomfort persists, contact your dental care provider.

How Long Does A Root Canal Last?

With proper care, a root canal-treated tooth can last a lifetime. Factors that affect longevity include:

• Practising good oral hygiene
• Attending regular check-ups
• Avoiding hard or sticky foods
• Completing the restoration with a dental crown

Some treated teeth may eventually require retreatment, but many last for decades.

Frequently Asked Questions

Does root canal hurt more than a filling?

Most patients describe a root canal as similar to getting a filling, just slightly longer. The local anaesthetic ensures you stay comfortable during the process.

Can I drive after a root canal?

Yes, you can usually drive immediately after the procedure unless your dentist advises otherwise.

However, if your dentist has used any sedation or you’re feeling particularly drowsy or unwell, it’s always best to arrange for someone to drive you or rest before heading home.

Can children have a root canal?

Yes, children can undergo root canal therapy if the dental pulp of a tooth gets infected or inflamed. In these cases, an adapted form of the procedure, often referred to as paediatric root canal treatment, is used to suit the needs of younger patients.

If your child shows signs of tooth infection or persistent pain, it’s best to consult a dentist experienced in children’s dental care.
