Does A Root Canal Treatment Cause Breast Cancer?
It’s natural to feel concerned about the safety of your health, especially when undergoing medical procedures. Over the years, there have been various claims and misconceptions about the potential risks of root canal treatment, with one of the more alarming rumors suggesting a link between root canal treatment and breast cancer. This can understandably cause confusion and anxiety for patients.
However, we’re here to provide some clarity and put your mind at ease. Extensive scientific research has confirmed that root canal treatment does not cause breast cancer. Let’s take a closer look at where this myth comes from and why you can feel confident in your dental care.
Where Did This Misconception Come From?
The confusion surrounding root canal treatment and breast cancer mainly stems from a Netflix documentary called The Root Cause. The film was produced by a naturopath filmmaker who suggested that root canals were linked to a variety of serious health issues, including breast cancer and cardiovascular disease. While the documentary sparked discussions, it was based on unverified claims rather than solid scientific research. In fact, it faced significant criticism from the medical and dental communities for spreading misinformation.
What Does the Science Say?
The truth is that there is no scientific evidence supporting the idea that root canals cause breast cancer. A root canal is a dental procedure that’s performed to save a tooth that has become infected or non-vital. During the procedure, the dentist removes the infected pulp from inside the tooth, carefully cleans and disinfects the root canal, and then seals it to prevent further infection.
Root canal treatments are a standard, safe procedure used to preserve your natural tooth and restore dental health. Breast cancer, on the other hand, is influenced by factors such as genetics, hormonal changes, and lifestyle choices like diet and exercise. There is simply no connection between a dental procedure like a root canal and an increased risk of breast cancer.

Should You Be Concerned About Root Canals?
Understandably, any medical procedure can cause concern, but when it comes to root canal therapy, there’s no need to worry about it affecting your overall health, especially not in terms of cancer risk. Root canals are a well-researched treatment designed to eliminate infection and relieve pain while saving your natural tooth. The risks associated with the procedure are minimal and generally related to the tooth itself, not to your overall health.
What Should You Do If You Have Concerns?
If you’re experiencing discomfort after a root canal or feel that something isn’t quite right, it’s always a good idea to seek a second opinion. Sometimes, complications can arise from the tooth itself, but these are typically dental issues that can be easily resolved by your dentist. Rest assured, any discomfort you experience is not related to breast cancer.
