This brief blogpost will educate you about everything related to root canal infection. Continue reading as we start with an intro of Root canal. 

What Is A Root Canal?

A root canal is a dental procedure designed to treat infection or damage within the pulp of a tooth. The pulp is located in the tooth’s centre. It contains nerves, blood vessels and connective tissue. When it becomes infected due to deep decay, cracks, trauma or any other reason a root canal becomes necessary to save the tooth and relieve pain.

The dentist removes the infected pulp, cleans and disinfects the root canals in this process. Then it is filled with a biocompatible material to avoid any discomfort. It prevents the spread of infection. 

A crown is often placed on the treated tooth after root canal to restore its strength and functionality. Root canals play a crucial role in saving your natural teeth under sensitive conditions. 

Infection Symptoms After Root Canal

Feeling discomfort and pain is normal after root canal. But in case you develop an infection you will feel some other symptoms as well. Following are some of the common symptoms of an infection;  

  • Pain: Persistent or increasing pain after a root canal may indicate the infection has not been completely eradicated. It may also be due to the problem with the treated tooth.
  • Abscess: Abscess is a collection of pus. You may also develop it accompanied with swelling and inflammation. It is also a symptom of infection..
  • Tooth Discoloration: Discoloration of the tooth may be a sign of internal bleeding or decay, suggesting that the root canal treatment may not have been successful in removing all infected tissue.
  • Numbness: Numbness or tingling in the surrounding areas could indicate nerve damage, which may occur during the root canal procedure or due to persistent infection.
  • Chronic Bad Breath: Infection in the root canal can lead to the release of foul-smelling gases or substances, causing chronic bad breath.
  • Fatigue: Systemic symptoms like fatigue may occur when the body is actively fighting off an infection, and the immune system is under stress.
  • Fever: A fever is a common sign of infection as the body’s natural response to pathogens. If the infection from the root canal spreads, it can lead to a systemic response, causing a fever.
  • Swollen Tissue: Inflammation and swelling may occur if the infection spreads to the surrounding gums or tissues.
  • A Bad Taste: A bad taste in the mouth may result from the discharge of pus or other infectious materials, contributing to unpleasant oral sensations.

Other Root Canal Problems

Alongside infection, the root canal can also cause other problems as well. Although these are very rare but possible. Let’s take a look at the details of these problems. 

Teeth Breaking

After a root canal procedure, the risk of teeth breaking becomes a concern if a crown is not promptly placed on the treated tooth. The decay that necessitated the root canal weakens the tooth, and without the protective support of a crown, the tooth may become brittle, crack, or break. This lack of timely intervention can lead to additional dental complications, necessitating further treatments or, in severe cases, complete removal of the compromised tooth.

Root Fracture 

Root fracture is another potential issue post-root canal, arising from decay or pre-existing, often imperceptible cracks. When a root fracture occurs, discussions with an endodontist become crucial to explore possible treatment options or the potential need for tooth extraction. This fracture compromises the integrity of the tooth’s root, posing challenges to its long-term viability and necessitating careful consideration of the best course of action to preserve oral health.
