Debunking Dental Myths: New Book Reveals Surprising truths About Oral Health

Paris, France – In a groundbreaking new book, “50 mythos on chicots,” published June 2025, Dr. Sacha-Gabriel Ayache tackles widespread dental myths,offering a fresh perspective on oral hygiene. The book challenges conventional wisdom on topics ranging from toothbrushing techniques too the impact of sugar and the connection between oral health and overall physical well-being. Understanding these dental myths is crucial for maintaining optimal oral health .

Challenging Common Dental Care Misconceptions

Dr. Ayache’s book, published by Vuibert editions, addresses several long-held beliefs about dental care, providing evidence-based insights to help readers make informed decisions about their oral health. Here are some of the key myths debunked:

The Truth About Wetting Your Toothbrush

The common suggestion to avoid wetting your toothbrush before applying toothpaste, promoted by the French Union for oral Health (UFSBD), suggests that water dilutes the fluoride, reducing its effectiveness. However,Dr. Ayache argues that the evidence supporting this claim is not conclusive. While it might be relevant for individuals with poor dental hygiene, wetting the toothbrush can actually improve the brushing experience for most people. The foam created can give the impression of better cleaning, motivating individuals to brush longer and more thoroughly.

Pro Tip: If you find dry brushing unpleasant,wetting your toothbrush is unlikely to significantly reduce the benefits of fluoride toothpaste.

Sugar’s role in Cavity Formation

While sugar has long been demonized as a primary cause of cavities, Dr. Ayache offers a more nuanced perspective. He explains that sugar does contribute to the formation of cavities by feeding bacteria that attack teeth. However,with proper oral hygiene practices,such as regular and thorough brushing,consuming sugar in moderation is not necessarily detrimental. The key is to maintain a consistent oral care routine to counteract the effects of sugar consumption. According to the world Health Organization (WHO), limiting free sugars intake to less than 10% of total energy intake is part of a healthy diet .

The Systemic Impact of Dental Infections

A risky myth is that dental infections only affect the mouth. Dr. Ayache emphasizes that the mouth serves as a gateway to the entire body, connected to vital organs through the respiratory and digestive systems. Bacteria from gum infections, such as periodontitis, can increase the risk of serious conditions like Alzheimer’s disease. Furthermore,bacteria from cavities can enter the bloodstream,potentially damaging the heart and leading to endocarditis. Pregnant women with untreated dental issues face higher risks of premature birth or low-weight babies. The American Academy of Periodontology highlights the connection between periodontal disease and other health conditions .

Did You Know? Periodontal disease affects nearly half of adults over 30 in the United States, according to the CDC.

Ultimately, Dr. Ayache’s message is one of empowerment through knowledge. By understanding the truth behind common dental myths, individuals can take proactive steps to protect their oral health and overall well-being. Regular dental visits, proper brushing and flossing techniques, and a balanced diet remain essential components of a thorough oral care routine .
