Myths and Facts about Root Canal Treatments

Here are some of the most common myths about root canal treatments:


Myth #1: Root Canals Are Excruciatingly Painful Procedures

Fact: Root canal treatments used to be painful due to inadequate anesthesia and antiquated procedures. However, the latest dental technology and local anesthetics have made root canals more comfortable. Patients undergoing a root canal today typically experience little to no pain during the procedure.


Myth #2: Extracting the Infected Tooth Is a Better Alternative to a Root Canal

Fact: Some believe extracting the infected tooth is simpler and less expensive than undergoing a root canal. However, preserving the natural tooth should always be the priority whenever possible. Tooth extraction may seem like a quicker fix, but it can lead to several complications, such as misalignment of neighboring teeth, difficulty chewing, and loss of jawbone density. Besides, replacing the extracted tooth with dental implants or bridges is more costly and time-consuming than saving the natural tooth through a root canal.


Myth #3: Root Canals Always Require Multiple Visits to the Dentist

Fact: This is not always true. Depending on the infection's severity and the tooth's complexity, your dentist may decide the number of visits for the root canal treatment.


If you are experiencing severe pain, the dentist may prescribe medication to reduce the pain on your first visit. Then, they will address the infected matter causing the pain in the following two appointments. The dentist will then seal the root canal in preparation for a crown.


Myth #4: Root Canal-Treated Teeth Become Weaker and More Prone to Fractures

Fact: Some believe teeth treated with root canals become weaker and more likely to fracture. In reality, root canal-treated teeth are not inherently weaker. With proper care and maintenance, a tooth that has undergone a root canal can last a lifetime, functioning just like a natural tooth.


Myth #5: Antibiotics Alone Can Cure Root Canal Infections

Fact: While antibiotics can help temporarily manage the symptoms of a root canal infection, they cannot eradicate the underlying issue. The infection occurs within the tooth's pulp, which is inaccessible to antibiotics. Root canal treatment involves removing the infected pulp and thoroughly cleaning the tooth's interior to eliminate the infection's source. Without root canal treatment, the infection can spread to surrounding tissues and cause further complications.


Myth #6: Children Don’t Need Root Canals Because Their Teeth Will Fall Out Anyway

Fact: While it's true that children's primary (baby) teeth will eventually fall out, they play a crucial role in their oral development. Untreated root canal infections in primary teeth sometimes lead to pain, abscesses, and complications that may affect the eloping permanent teeth. Root canal treatments for primary teeth can prevent potential issues in the future.


Myth #7: You Can Treat a Root Canal Infection with Home Remedies

Fact: While home remedies can temporarily alleviate some symptoms of a dental infection, they cannot cure a root canal infection. A dental consultation can help you decide whether you need root canal treatment. Home remedies cannot replace the need for professional dental intervention.


Myth #8: Root Canal Treatment Is Expensive and Not Worth the Cost

Fact: The cost of root canal treatment may vary depending on factors such as the tooth's location, the complexity of the procedure, and the expert performing it. While root canal treatment may involve initial expenses, it is a cost-effective solution in the long run. Preserving the natural tooth through a root canal can avoid the need for more expensive dental restorations or tooth replacements.


Myth #9: Root Canals Can Lead To Gum Disease or Periodontal Problems

Fact: Root canal treatment addresses issues within the tooth's pulp chamber and root canals, not the surrounding gums. When performed correctly, root canal treatment can help alleviate gum inflammation and prevent further complications, as it removes the source of infection and promotes healing.


Myth #10: A Root Canal Will Remove All Sensation from the Treated Tooth

Fact: A root canal removes the dental pulp, which contains nerves, blood vessels, and connective tissue. As a result, the tooth may lose some sensitivity to temperature changes, but it will still respond to pressure and touch. The tooth will continue to function normally for biting and chewing.


Myth #11: Root Canal Treatment Causes Allergies or Other Adverse Reactions

Fact: No scientific evidence supports the claim that root canal treatment causes allergies or adverse patient reactions. The routine dental professionals who perform root canals are experts in their field. The materials used in root canal treatment, such as gutta-percha (a rubber-like material) and dental cement, have a long history of safe use in dentistry. Allergic reactions to these materials are rare.


Myth #12: You Don’t Need a Root Canal If You Don’t Have Visible Cavities

Fact: While visible cavities are a common sign of tooth decay, root canal infections can occur without apparent cavities. Dental infections may result from cracks in the tooth, deep fillings, or even trauma to the tooth. Endodontists use X-rays and other diagnostic tools to identify root canal infections that may not be apparent on the surface.


Myth #13: You Can Delay Root Canals If You Do Not Have Pain

Fact: Delaying or avoiding root canal treatment can severely affect oral health. Root canal infections do not go away on their own; they worsen over time and can spread to other teeth or surrounding tissues, leading to more extensive dental problems. Timely root canal treatment is essential to prevent complications and preserve your natural tooth.


Myth #14: Root Canals Are Only for Molars or Back Teeth

Fact: While molars and premolars are more susceptible to dental infections due to their complex anatomy, root canal treatments can be performed on any tooth, including front teeth. Regardless of the tooth’s location, infection or inflammation in the dental pulp determines whether a root canal is necessary.


Myth #15: Root Canals Are Outdated and Not Used in Modern Dentistry

Fact: Root canal treatment is a standard and widely accepted procedure in modern dentistry. It has evolved significantly over the years, with improved techniques and equipment making it more efficient and comfortable for patients.
