Fact vs Myth About Root Canals
Posted on 4/15/2026 by Sunnyside Dentistry |
Let's talk about root canals. This dental procedure has a bit of a reputation, and not all of it is accurate. A lot of what people think they know about root canals comes from old stories or misunderstandings. My goal is to separate fact from fiction so you can understand what a root canal really involves and why it might be recommended for you.
What is a Root Canal, Anyway?
Inside your tooth, beneath the hard enamel and a layer called dentin, there's a soft tissue called pulp. This pulp contains nerves, blood vessels, and connective tissue that help your tooth grow during development. Once a tooth is fully formed, it can survive without the pulp. When this pulp becomes infected or inflamed, a root canal procedure might be necessary to save the tooth.
The Myth: Root Canals are Painful
This is probably the biggest misconception. The truth is, the infection that necessitates a root canal is what causes the pain. A root canal procedure itself is designed to relieve that pain. Modern techniques and anesthetics make the procedure relatively painless. You'll likely experience more discomfort from a simple filling than from a root canal. The dentist numbs the area completely, so you shouldn't feel anything during the treatment. Post-procedure, there might be some mild soreness, easily managed with over-the-counter pain relievers.
The Fact: Root Canals Save Teeth
The primary purpose of a root canal is to save a tooth that would otherwise need to be extracted. Removing a tooth can lead to other dental problems, like shifting teeth, difficulty chewing, and bone loss in the jaw. Preserving your natural teeth is always the best option whenever possible. Root canals allow you to keep your natural tooth, maintaining your bite and smile.
The Myth: Root Canals Make You Sick
This myth has circulated for years, but there's no scientific evidence to support it. The American Dental Association and other leading dental organizations have debunked this claim. The idea that bacteria trapped in the tooth after a root canal can cause systemic illness is simply not true. Properly performed root canals eliminate the infection, preventing it from spreading.
The Fact: After a Root Canal, the Tooth May Need a Crown
After a root canal, the tooth can become more brittle. This is because the pulp, which provides nourishment and moisture, has been removed. To protect the tooth from fracture, a crown is often placed over it. The crown strengthens the tooth and restores its function and appearance. Think of it as a helmet for your tooth!
The Myth: Root Canals are a Cosmetic Procedure
While a crown, which is often placed after a root canal, can improve the appearance of a tooth, the primary goal of a root canal isn't cosmetic. It's about saving a tooth and restoring its health. Sometimes, the tooth can darken after the procedure, but this can often be addressed with internal whitening techniques. If you enjoy a regular drink of coffee or tea, this can also contribute to tooth staining.
The Fact: Root Canals Have a High Success Rate
Root canals have a very high success rate. With proper care and maintenance, a tooth that has undergone a root canal can last a lifetime. This includes regular brushing, flossing, and check-ups with your dentist. Think of a root canal as giving your tooth a second chance!
