As an endodontist, I often encounter patients who aren’t sure whether they need a root canal or are simply experiencing a minor dental issue. While no one enjoys the thought of needing extensive dental treatment, it’s important to recognize when something more than a routine cavity is going on. Ignoring these signs can lead to greater pain and the potential loss of your tooth.

 

In this post, I’ll guide you through some of the most common signs that may indicate the need for a root canal. Understanding these symptoms will help you make an informed decision about when to seek care from your dentist or an endodontist.

 

What is a Root Canal?

 

Before we dive into the signs, let’s clarify what a root canal actually is. A root canal is a procedure designed to save a natural tooth that has become severely inflamed, infected, or damaged. It involves removing the affected tissue from the inside of the roots of the tooth, cleaning and disinfecting the canals, and then sealing it to prevent future infection.

 

1. Persistent Tooth Pain

 

One of the most common indicators that something is wrong is ongoing tooth pain. If you have consistent, throbbing pain that doesn’t seem to go away, it could be a sign that the tissue inside your tooth is inflamed or infected.

 

Tooth pain can vary in severity and can occur spontaneously or when you bite down, touch the tooth, or consume hot or cold foods. The pain may radiate to your jaw, face, or even down your neck, making it difficult to pinpoint the exact location. If you experience any of these sensations, it’s important to schedule an appointment with your dentist as soon as possible for evaluation..

 

2. Prolonged or Abnormal Sensitivity to Hot and Cold

 

Sensitivity to hot or cold temperatures is normal to a certain extent, especially if you have exposed dentin from gum recession or enamel wear. However, if you notice that the sensitivity lasts long after you’ve finished eating or drinking and becomes more severe over time, this could indicate that the nerve and tissue inside your tooth is inflamed or irritated..

 

3. Discoloration of the Tooth

 

If you notice that one of your teeth is becoming discolored, especially if it appears grayish or dark in comparison to the surrounding teeth, this could be a sign of nerve damage. When the tissue inside of your tooth dies, the dead tissue can cause internal staining that cannot be corrected with simple whitening treatments.

 

This discoloration typically occurs due to trauma or long-term decay that has reached the nerve tissues of the tooth. In such cases, a root canal may be necessary to remove the infected tissue and restore the tooth’s health.  Frequently a crown will be recommended by your restorative dentist to improve the cosmetic appearance of the tooth.

 

4. Swollen or Tender Gums

 

Swelling or tenderness in the gums near the affected tooth is another sign of potential infection. While gum swelling can sometimes be caused by gum disease or food particles getting stuck, persistent or recurring swelling often points to deeper problems within the tooth.

 

If your gums are swollen, red, or tender to the touch, and the swelling does not subside, it could mean that the infection has spread from the root of the tooth to the surrounding tissues. You may also notice a small, pimple-like bump on your gums near the affected tooth, called a sinus tract or “gum boil”.

 

5. Pain When Chewing or Touching the Tooth

 

If your tooth hurts when you apply pressure, such as when chewing or even lightly tapping it, this could indicate that the tooth is inflamed or infected. Pain with pressure is often a sign that the infection has progressed and is affecting the nerves within the tooth. It’s important to address this issue quickly, as waiting too long could lead to more serious complications, including loss of the tooth.

 

6. A Chipped or Cracked Tooth

 

A cracked or chipped tooth can expose the nerve tissue inside, making it more susceptible to infection. Even if the crack is not immediately painful, bacteria can still enter through the damaged tooth and cause inflammation or infection over time.

 

If you’ve experienced trauma to your mouth, or if you notice that one of your teeth is cracked or chipped, it’s essential to see your dentist for an evaluation. In many cases, a root canal may be required to save the tooth.

 

7. A Loose Tooth

 

If your tooth feels loose, it could be a sign of infection. When an infection spreads to the root of the tooth, it can cause the surrounding bone to weaken, resulting in the tooth becoming loose. In this case, a root canal might be necessary to remove the infection and stabilize the tooth.

 

When to See Your Dentist or an Endodontist

 

If you’re experiencing any of the signs mentioned above, it’s important to schedule an appointment with your dentist or an endodontist. Early detection and treatment can save your tooth and prevent the infection from spreading to other parts of your mouth or body.

 

An endodontist specializes in diagnosing and treating problems related to the tissue and canals inside of the tooth, and they are experts in performing root canal treatments. If your dentist suspects that you need a root canal, they will often refer you to an endodontist for further evaluation and treatment.

 

What Happens During a Root Canal?

 

If it’s determined that you need a root canal, don’t panic! Modern root canals are much more comfortable and efficient than their outdated reputation suggests.

 

Here’s what you can expect during the procedure:

 

    1.    Local Anesthesia – The first step is numbing the area around the affected tooth to ensure you remain comfortable throughout the procedure.

    2.    Accessing the Canals – A small opening is made in the biting surface or crown of the tooth to access the infected or inflamed tissue.

    3.    Cleaning and Shaping the Canals – The tissue is carefully removed, and the canals inside of the tooth are cleaned and shaped.

    4.    Filling the Tooth – The cleaned canals are filled with a biocompatible material, and the opening is sealed to prevent further infection.

    5.    Restoring the Tooth – In most cases, a crown is placed by your restorative dentist on the treated tooth to restore its function and appearance.
