Everything To Know About Root Canal Treatments


You may have heard about root canal treatments if you’ve ever experienced severe tooth pain due to a deep cavity or dental infection. Root canals have gained a somewhat intimidating reputation, but they are crucial procedures that can save your natural teeth and alleviate excruciating pain. In this article, we’ll dive deep into “Everything To Know About Root Canal Treatments” to dispel myths and provide comprehensive insights, ensuring you’re well-informed before undergoing this dental procedure.

What Are Root Canal Treatments?

Root canal treatment, or endodontic therapy, is a dental procedure that aims to repair and save an infected or severely damaged tooth. During this process, the tooth’s pulp and nerve are removed, and the interior of the tooth is cleaned, disinfected, filled, and sealed. The pulp in the root canals contains blood vessels, nerves, and connective tissues. When the pulp becomes infected, it can lead to a painful abscess; without treatment, the tooth may require extraction.

Signs You May Need a Root Canal

1. Persistent Toothache

If you experience lingering tooth pain, especially when eating or applying pressure, it could indicate pulp inflammation or infection. A persistent toothache that doesn’t go away with over-the-counter painkillers might suggest that you need a root canal treatment. Ignoring the pain can lead to further complications and may require more extensive dental procedures.

2. Sensitivity to Hot or Cold

Sensitivity to temperature changes that linger after removing the temperature source may indicate a damaged pulp. When a tooth’s pulp becomes infected or inflamed, it loses its ability to insulate the nerves from extreme temperatures. If you feel pain when consuming hot or cold food and beverages, it’s time to consult your dentist.

3. Gum Swelling

Swelling and tenderness in the gums near the affected tooth can indicate infection. When the pulp inside the tooth becomes infected, the bacteria can spread to the surrounding tissues, causing inflammation and gum swelling. If you notice any unusual lumps or swollen areas near a specific tooth, it’s essential to seek dental attention promptly.

4. Discolored Tooth

A tooth that has darkened or changed color may indicate that the pulp is damaged. When the pulp becomes infected, it can cause the tooth to change its color, turning it grayish or blackish. This discoloration indicates that the tooth’s nerve and pulp may be compromised, necessitating a root canal treatment.

5. Painful Abscess

A small, pimple-like bump on the gums, accompanied by pain and pus, may indicate an abscessed tooth. An abscess is a severe infection that forms at the tooth’s root or in the space between the tooth and gums. It can be excruciating and requires immediate attention to prevent the disease from spreading.

The Root Canal Procedure Explained

When your dentist determines you need a root canal treatment, you might be curious about the step-by-step procedure. Here’s a detailed explanation of what to expect during a root canal:

1. Initial Assessment

Your dentist will examine your tooth, possibly taking X-rays, to determine the extent of the damage and confirm the need for a root canal. X-rays help your dentist identify the location and severity of the infection and assess the root canal’s complexity.

2. Anesthesia

Before the procedure begins, a local anesthetic will be administered to numb the area around the affected tooth, ensuring a comfortable experience. The drug will prevent you from feeling pain during the root canal treatment.

3. Accessing the Pulp

Your dentist will create a small opening in the tooth’s crown to access the infected pulp and nerve. This access point allows your dentist to reach the pulp chamber and root canals.

4. Removing the Pulp

The infected or inflamed pulp and nerve tissue will be carefully removed from the root canals using specialized tools. The dentist will clean and shape the channels to remove all infected material.

5. Cleaning and Disinfection

The tooth’s interior and root canals will be meticulously cleaned and disinfected to eliminate any remaining bacteria. This step is crucial in preventing further infection and promoting proper healing.

6. Filling and Sealing

The cleaned interior will be filled with a rubber-like material called gutta-percha, and the tooth’s access opening will be sealed with a temporary filling. Gutta-percha provides a stable and biocompatible material to seal the root canals and prevent recontamination.

7. Restoration

A dental crown may be recommended to strengthen and protect the treated tooth. A dental crown provides additional protection, especially if the tooth had significant decay or damage before the root canal.

8. Follow-Up

After the root canal treatment, you will schedule a follow-up appointment to ensure proper healing and assess the tooth’s condition. The dentist will check for signs of infection and ensure the treated tooth is healing as expected.


The Global Burden of Disease 2017 found that the most common of all health issues globally is untreated tooth decay that affects permanent teeth.


Benefits of Root Canal Treatments

Root canal treatments offer several significant benefits, making them a preferred choice over tooth extraction. Some advantages include:

1. Preservation of Natural Tooth

Root canals allow you to keep your natural tooth, maintaining proper chewing function and preventing neighboring teeth from shifting. By preserving the natural tooth, you avoid the potential issues that can arise with tooth extraction, such as changes in bite alignment and the need for additional dental work.

2. Pain Relief

Root canal treatments alleviate tooth pain caused by infection, allowing you to resume daily activities without discomfort. After the root canal, the condition is removed, and the tooth is sealed, relieving the pressure and pain associated with a dental abscess.

3. Improved Oral Health

By removing the infected pulp, root canals prevent the spread of infection to other parts of the mouth. This eliminates the risk of the disease causing more extensive damage to neighboring teeth, gums, or jawbone.

4. Efficient Chewing

Restored teeth function like natural teeth, enabling efficient chewing and maintaining a balanced bite. You can enjoy your favorite foods without discomfort with a successful root canal and proper dental restoration.

Common Myths About Root Canal Treatments

Root canals have unfortunately garnered a reputation for being painful and unpleasant. Let’s debunk some common myths surrounding root canal treatments:

1. Myth: Root Canals Are Painful

With modern anesthesia and advanced techniques, root canal procedures are no more painful than getting a dental filling. Dentistry has come a long way, and local anesthesia ensures patients experience minimal discomfort.

2. Myth: Root Canals Cause Illness

There is no scientific evidence linking root canal treatments to systemic health issues. The misconception that root canals cause illness originated from outdated and debunked research. Root canals are safe and effective dental procedures when performed by a qualified professional.

3. Myth: Extraction Is Better Than a Root Canal

Saving your natural tooth through a root canal is generally more beneficial than extraction, as it maintains oral function and aesthetics. Losing a tooth can lead to problems with chewing, speech, and the alignment of surrounding teeth. Restoring and preserving your natural tooth is always the preferred option whenever possible.


Contrary to popular belief, root canal treatments are highly effective procedures designed to save your natural teeth and relieve pain caused by dental infections. By opting for a root canal, you can preserve your oral health, maintain proper chewing function, and avoid the potential drawbacks of tooth extraction. Remember to consult your dentist if you experience any signs of tooth infection to determine whether a root canal treatment is best for you.
