From oil pulling to charcoal toothpaste, the internet is full of dental trends. In this post, we will debunk common myths about oral care and set the record straight with evidence based facts so you can make informed decisions for your smile.
Oil Pulling vs. Mouthwash
Myth: Swishing oil is better than mouthwash for your oral health.
Fact: While oil pulling may reduce salivary bacteria, it does not significantly reduce plaque or gingivitis compared to trusted antiseptics. A study published in the International Journal of Dental Hygiene found that Chlorhexidine remained superior in reducing the amount of plaque, compared to oil pulling. Although, oil pulling will not cause you any harm it is not a replacement for scientifically proven methods of using mouthwash with chlorhexidine or fluoride.
Root Canals and Cancer
Myth: Root canals can lead to cancer or systemic disease.
Fact: There is no credible scientific evidence linking root canal therapy to cancer. The Canadian Cancer Society explicitly states there’s no credible evidence to suggest this link. Authoritative dental organizations like the American Association of Endodontists affirm root canals are safe and effective. However, this myth traces back to outdated theories with no basis in modern research.
Charcoal Toothpaste

Myth: Charcoal toothpaste is a healthy, natural alternative for brushing and whitening.
Fact: Charcoal toothpaste is not a healthy alternative to fluoride toothpaste. It’s abrasive and can wear down your enamel, exposing the softer inner layer of the tooth and causing sensitivity. If you’re concerned about fluoride in your toothpaste, you can speak to your dentist about safer, non-fluoride options.
Fluoride Safety
Myth: Fluoride is unsafe and should be avoided.
Fact: Fluoride remains a safe and effective tool for cavity prevention when used properly. A mere pea-sized amount of fluoride toothpaste along with drinking water with 0.6 mg/L of fluoride strengthens enamel and combats decay. Consequently, the use of fluoride is backed by decades of scientific research and supported by major public health organizations.
Modern Day Root Canals
Myth: Root canals are painful, risky, and can cause other health problems.
Fact: Today’s root canal treatments are highly effective, meticulously cleaning and sealing the tooth to prevent reinfection. In rare cases where healing is incomplete, follow-up care or alternative treatments are available.
