What is a Root Canal?

A root canal is a dental treatment that removes infection from the pulp inside your tooth. The pulp contains nerves, blood vessels, and connective tissue that keep your tooth alive. When the pulp becomes inflamed or infected, it can cause severe pain and discomfort.

During a root canal procedure, the dentist will remove the infected tooth pulp, clean and shape the inside of the tooth, and then fill and seal it to prevent further infection. The dentist may also place a crown over the natural tooth to provide additional protection.

Key Takeaway

Root canal therapy is necessary to save a tooth that would otherwise have to be removed due to infection or damage. Identifying early signs of root canal problems, such as persistent pain, tooth discoloration, or gum swelling, is vital. Maintaining good dental hygiene and regular dental checkups can significantly reduce the likelihood of needing such dental procedures.

Dental Quiz

Are you experiencing tooth pain or other symptoms? Take our dental quiz to find out if you need a root canal.

1. Are you sensitive to hot or cold?

Tooth sensitivity is your body’s way of telling you something is wrong.

If you feel sharp pain while eating or drinking hot or cold foods, it may indicate nerve damage in your tooth. Sometimes, sensitivity can be triggered by something as simple as a breath of cold air. 

Another warning sign is if the tooth sensitivity persists after removing the initial trigger, like taking away the cold drink or discontinuing the hot food.

This sensitivity can also indicate inflammation or infection in the pulp inside your tooth, so you should book an appointment with your dentist.

2. Do you have tooth discoloration?

As we age, it is natural for our teeth to darken. However, if a single tooth suddenly changes color and appears “dead,” it may indicate severe damage or infection of the tooth’s nerve.

The color change, particularly darkening or grayish tinges, may become more prominent over time and is often a sign of a significant dental problem. If you notice this change, do not hesitate to contact your dentist.

3. Do you have persistent pain or discomfort?

If you are experiencing ongoing or severe tooth pain, it may be a sign of an infected pulp. This pain can occur without any apparent reason and may even wake you up at night. You may also feel a dull ache or pressure that radiates to your jaw or ear.


Pay attention to the frequency and duration of the pain. If the pain continues or recurs over several days or weeks, it might indicate that the tooth’s nerve is compromised.

4. Are your gums tender and swollen?

Inflamed or infected pulp within the tooth can cause swelling in the surrounding gums. You may notice a pimple-like bump on the gum near the affected tooth—a condition known as a dental abscess. This bump can be sensitive to the touch and may leak pus.

Swelling should always be taken seriously and requires immediate attention. A dental abscess can lead to serious complications if left untreated. If you’re experiencing any gum swelling, make an appointment with your dentist immediately.

5. Have you had an injury or trauma to the tooth?

A traumatic blow to the face or mouth can have a delayed effect on the health of your tooth. The tooth’s nerve may have been irreversibly damaged even if the initial pain subsides after the injury. Over time, the tooth may become discolored and require treatment.

If you’ve experienced significant trauma to your teeth, you should be evaluated by a dentist as soon as possible. This proactive step can prevent serious problems and may even save the tooth from further damage.

6. Do you have a loose tooth?

An adult tooth should never be loose. A tooth that feels loose or unstable may be a sign of infection in the pulp. This instability can occur as the infection weakens the tooth’s structure and may require a root canal to save the tooth from extraction.

What if I Need a Root Canal?

You may need a root canal if you answered yes to one or more of these questions. However, only a dentist can make an accurate diagnosis, so this quiz should not be a substitute for professional advice.

Schedule an appointment with your dentist as soon as possible to discuss your symptoms and potential treatment options.

Root Canal Prevention

While root canal therapy can effectively treat infected pulp, it’s always best to prevent dental problems before they arise. Here are some tips to help keep your teeth and gums healthy:

  • Brush your teeth twice a day with fluoride toothpaste.
  • Floss daily to remove plaque and food particles from between your teeth.
  • Eat a balanced diet that is low in sugar and acidic foods.
  • Avoid tobacco products.
  • Visit your dentist regularly for check-ups and cleanings.

Following these simple steps can reduce your risk of tooth decay and maintain good oral health. Early detection and treatment are key to preventing more severe dental issues.
