What Is a Root Canal Infection and How Can You Prevent It

Root Canal

Root canal infection is a condition that can occur in teeth when the inner pulp or nerve of the tooth becomes infected or damaged. Bacteria can cause root canal infections, deep decay, repeated dental procedures on the same tooth, a crack or chip in the tooth, or trauma.

What Are the Symptoms?

Root canal infections can cause a wide range of symptoms, ranging from mild to severe. If you’re experiencing any of the following symptoms, it could be a sign of a root canal infection, and you should see your dentist as soon as possible:

1. Severe Pain

If you have a root canal infection, you may experience an intense, throbbing pain in your tooth that can sometimes radiate to other parts of your face or head. This pain can be constant or come and go, and it can worsen when you eat or drink something cold or hot.

2. Sensitivity to Temperature Changes

If you have a root canal infection, you may find that your tooth is sensitive to temperature changes. This means that drinking something cold or hot may cause a sharp, shooting pain in your tooth that can be quite unpleasant.

3. Swelling

Swelling around the affected tooth may be a sign of a root canal infection. This can cause your gums to look swollen and may make it difficult to open your mouth.

What Are the Causes?

Root canal infections can be extremely painful and uncomfortable, and can be caused by bacteria or trauma to the tooth. Knowing the potential causes of a root canal infection can help you avoid them and maintain your oral health.

1. Bacteria

The most common cause of a root canal infection is bacteria. If the bacteria enters your tooth, it can cause an infection that can spread to the root canal, resulting in a root canal infection. The bacteria can enter the tooth through a cavity or crack, a broken filling, or when food particles become trapped between teeth.

2. Trauma

Trauma to the tooth can also cause a root canal infection. For example, if the tooth is hit hard enough, it can cause the nerve inside the tooth to become infected. This can spread to the root canal, leading to a root canal infection.

3. Untreated Decay

Untreated decay can also lead to a root canal infection. If decay is not treated, it can spread to the root canal and cause an infection.

What to Do to Prevent Root Canal Infection?

Root canal infections are actually a common dental issue. Fortunately, there are several steps you can take to prevent root canal infections and keep your teeth healthy. 

1. Practice Good Oral Hygiene

One of the best ways to reduce the risk of root canal infection is to practice good oral hygiene. This means brushing and flossing your teeth regularly and using an antiseptic mouthwash. Doing so can help to remove plaque and bacteria that can cause infection.

2. Avoid Sugary Foods and Drinks

Eating sugary foods and drinks can increase the risk of developing cavities and other issues that can lead to root canal infections. Avoiding sugary treats and drinks can help keep your teeth healthy.

3. See Your Dentist Regularly

Visiting your dentist regularly is another important step in preventing root canal infection. Your dentist can identify any potential issues with your teeth and provide treatment to prevent infection.

4. Avoid Smoking

Smoking can increase the risk of root canal infection, as it can interfere with the body’s ability to heal. If you are a smoker, it is important to quit in order to reduce the risk of infection.

5. Follow Your Dentist’s Instructions

If your dentist recommends a root canal, it is important to follow their instructions for aftercare. This may include using an antiseptic mouthwash, avoiding certain foods, and taking any prescribed medications.


A root canal infection is a serious matter that should be addressed as soon as possible. If you think you may have an infection, it is important to see a dentist or endodontist right away. With prompt treatment, most infections can be successfully treated and the tooth saved.
