Root canals are a common dental procedure that is often misunderstood and surrounded by misconceptions. Many people have heard horror stories or myths about root canals that have led to fear and anxiety about the procedure. However, it is important to separate fact from fiction and understand the reality of root canals. In this article, we will debunk some of the most common misconceptions surrounding root canals and provide valuable insights based on research and expert opinions.

The Purpose of a Root Canal

Before diving into the misconceptions, it is essential to understand the purpose of a root canal. A root canal is a dental procedure performed to save a tooth that is severely infected or decayed. The procedure involves removing the infected pulp from the tooth’s root canal, cleaning and disinfecting the area, and then filling and sealing it to prevent further infection.

The primary goal of a root canal is to eliminate pain and save the natural tooth. By removing the infected pulp and sealing the tooth, the dentist can prevent the spread of infection to other teeth and restore the tooth’s functionality.

Misconception 1: Root Canals Are Painful

One of the most common misconceptions about root canals is that they are extremely painful. This misconception often stems from outdated information and experiences from the past when dental technology and techniques were not as advanced as they are today.

However, modern root canal procedures are relatively painless. Dentists use local anesthesia to numb the area before starting the procedure, ensuring that patients do not experience any pain during the treatment. In fact, many patients report feeling relief from the pain they were experiencing before the root canal.

Additionally, advancements in dental technology and techniques have made root canals more efficient and comfortable. Dentists now have access to better instruments and imaging technology, allowing them to perform the procedure with greater precision and accuracy.

Misconception 2: Root Canals Cause Illnesses

Another common misconception surrounding root canals is the belief that they can cause various illnesses and health problems. This misconception originated from a discredited theory known as “focal infection theory” proposed in the early 20th century.

The focal infection theory suggested that infections in the mouth, including those treated with root canals, could spread bacteria and toxins throughout the body, leading to systemic diseases such as heart disease, arthritis, and even cancer. However, extensive research and scientific studies have debunked this theory.

According to the American Association of Endodontists, there is no scientific evidence to support the claim that root canals cause systemic illnesses. In fact, root canals are a safe and effective way to eliminate infection and prevent the spread of bacteria to other parts of the body.

Misconception 3: Extraction is a Better Alternative

Some individuals believe that extracting a tooth is a better alternative to undergoing a root canal. They may think that removing the infected tooth entirely will eliminate the problem and prevent further complications.

However, extracting a tooth should be considered a last resort. Saving the natural tooth through a root canal is generally the preferred option for several reasons:

  • Preserving the natural tooth: The natural tooth is often the best option for maintaining proper oral function and aesthetics. Extracting a tooth can lead to other issues, such as shifting of adjacent teeth and bone loss.
  • Cost-effective: Root canals are usually more cost-effective in the long run compared to extracting a tooth and replacing it with a dental implant or bridge.
  • Less invasive: Root canals are a minimally invasive procedure compared to tooth extraction, which involves surgical removal of the tooth.

It is important to consult with a dentist or endodontist to determine the best course of action for each individual case. In many instances, saving the natural tooth through a root canal is the most beneficial option.

Misconception 4: Root Canals Require Multiple Appointments

Some people believe that root canals require multiple appointments, making the procedure more time-consuming and inconvenient. However, this is not necessarily true.

While some complex cases may require multiple appointments, the majority of root canals can be completed in a single visit. Advances in dental technology and techniques have made it possible for dentists to perform efficient and effective root canals in a shorter amount of time.

During the initial consultation, the dentist will evaluate the tooth and determine the best treatment plan. In some cases, a temporary filling may be placed to protect the tooth between appointments, but this is not always necessary.

Misconception 5: Root Canals Are Not Permanent

There is a common misconception that root canals are not permanent and that the treated tooth will eventually need to be extracted. However, this is not the case.

When performed by a skilled and experienced dentist or endodontist, a root canal can have a high success rate and provide a long-term solution for saving the tooth. The success of a root canal depends on various factors, including the extent of the infection, the quality of the dental restoration, and the patient’s oral hygiene habits.

After a root canal, the tooth is typically restored with a dental crown or filling to provide strength and protection. It is essential for patients to maintain good oral hygiene practices, including regular brushing, flossing, and dental check-ups, to ensure the longevity of the treated tooth.


Root canals are often misunderstood and surrounded by misconceptions. However, it is important to separate fact from fiction and understand the reality of this common dental procedure. Root canals are relatively painless, do not cause systemic illnesses, and are a preferred alternative to tooth extraction in most cases. They can often be completed in a single visit and have a high success rate when performed by a skilled dentist or endodontist. By debunking these misconceptions, individuals can make informed decisions about their dental health and seek appropriate treatment when necessary.
