Root Canal Symptoms: Don't Ignore the Warning Signs

Book an Appointment Today

If you've been experiencing discomfort in your teeth and wondering if it's time to consider a root canal, you're in the right place. This comprehensive guide will explore the telltale signs indicating needing a root canal.

We'll delve deep into the symptoms, FAQs, and everything you need to know about this dental procedure.

What is a Root Canal?

A root canal, formally known as endodontic therapy, is a dental procedure designed to treat an infection or damage deep within a tooth's pulp, which houses the tooth's nerve and blood vessels.

The infected or damaged pulp is removed during a root canal, and the tooth's interior is cleaned, disinfected, and sealed. This procedure aims to save the tooth from extraction while relieving pain and preventing the spread of infection.

Signs You Need a Root Canal

When it comes to your dental health, these signs are important to look out for and should not be ignored. 

Unrelenting Toothache

Have you been experiencing a persistent, throbbing toothache that just won't go away, no matter what you do? This could be one of the earliest and most glaring signs that a root canal may be in your future. The pain often intensifies when you chew, apply pressure, or consume hot or cold foods.

Sensitivity to Hot and Cold

Does a sip of your favorite hot beverage or a bite of ice cream send shockwaves of pain through your teeth?

If so, it's a sign that the nerves inside your tooth may be compromised. This heightened sensitivity is often a red flag for a root canal.

Swollen Gums

Swollen gums around a specific tooth can indicate infection. If your gums are tender, red, and swollen, it's crucial to consult your dentist promptly. Ignoring this sign may lead to more severe complications.

Darkened or Discolored Tooth

A tooth that has turned gray, black, or darker than its neighbors may be a sign of a dying nerve. Discoloration often results from internal damage, and a root canal may be necessary to salvage the tooth.

Pimple on the Gums

A pimple-like bump on your gum, known as a gum boil or dental abscess, clearly indicates infection. It occurs when pus accumulates near the tooth's root. Ignoring this sign can lead to further complications.

Painful Chewing

If you experience pain while chewing or applying pressure to a specific tooth, it's time to take notice. This discomfort can be a symptom of an infected tooth pulp, which may necessitate a root canal.

Lingering Bad Taste

An unpleasant, persistent taste in your mouth that doesn't go away despite your best efforts at oral hygiene could be linked to an infected tooth. The taste often results from pus draining from the tooth's root.

High Sensitivity to Touch

If touching or tapping on a tooth causes severe pain, it strongly indicates an underlying issue. This heightened sensitivity to touch could signal the need for a root canal.

Gum Recession

Receding gums can expose the tooth's roots, making them more susceptible to infection. If you notice your gums pulling away from your teeth, it's time to consult your dentist.

Cracked or Chipped Tooth

A cracked or chipped tooth can create an entry point for bacteria to reach the inner pulp. If left untreated, it can lead to infection and a root canal.

The Root Canal Process

Now that we've clarified what a root canal is, let's take a closer look at the step-by-step process involved in this dental treatment.

Examination and Diagnosis

The first crucial step in the root canal process is a thorough examination by your dentist. They will assess your symptoms, take X-rays, and perform tests to determine the extent of the infection or damage.

Local Anesthesia

Before the procedure begins, your dentist will administer local anesthesia to ensure you are comfortable and pain-free during the root canal. Contrary to common misconceptions, root canals are virtually painless, thanks to the effectiveness of anesthesia.

Isolation and Access

A rubber dam is placed around the tooth undergoing the root canal to keep the area clean and dry. This isolation prevents saliva and other contaminants from entering the area. Your dentist will then create an access opening in the tooth's crown to reach the pulp chamber.

Removal of Infected Pulp

Your dentist will carefully remove the infected or damaged pulp from the pulp chamber and root canals using specialised instruments. This step is crucial for eliminating the source of infection.

Cleaning and Shaping

Once the infected pulp is removed, the tooth's interior is meticulously cleaned and shaped to prepare it for the filling material. This ensures that no bacteria or debris remains inside the tooth.

Filling and Sealing

After cleaning and shaping, your dentist will fill the empty pulp chamber and root canals with a biocompatible material, typically a rubber-like substance called gutta-percha. The access opening is sealed with a temporary or permanent filling.


In most cases, a tooth that has undergone a root canal will require a crown to protect and strengthen it. 

Your dentist will take impressions of your tooth to create a customized crown that matches your natural teeth in appearance and function. The crown is then permanently cemented to the tooth.

Recovery and Aftercare

Following the root canal, you may experience mild discomfort or soreness, which can usually be managed with over-the-counter pain relievers. Your dentist will provide you with instructions for post-procedure care and follow-up appointments to monitor your healing progress.
