A prevalent myth suggests that root canals trap toxins and lead to health problems. In reality, root canals are beneficial. They effectively remove infections within the tooth, preventing further complications. The misconception may stem from misinformation sometimes propagated by misleading documentaries.

"The belief that root canals cause health issues lacks scientific evidence."

There is a common misconception that fluoride toothpaste is toxic. This arises when studies about high doses of fluoride are misinterpreted. In typical, everyday use, fluoride is safe and has proven benefits in combating tooth decay. Social media often disseminates this misinformation, but it’s important to remember the principle that toxicity is dose-dependent.

"Anything can be toxic at high doses—even oxygen."

It is crucial to critically evaluate dental health information, especially from non-expert sources. Understanding the risks and benefits of root canals, fluoride, and teeth whitening can help you maintain better oral health and avoid practices based on myths. Always consult with dental professionals when in doubt about the best practices for your oral care.
