A London-based dentist, Shaadi Manouchehri, has gained attention online by disclosing what she refers to as the “five things that your dentist doesn’t want you to know.” In a viral video posted on TikTok, Manouchehri, an award-winning cosmetic dentist and director at the London School of Facial Aesthetics, shared insights on maintaining clean and healthy teeth. Newsweek delves into the validity of her claims and seeks input from dental studio owners in the U.S.
Manouchehri’s tips cover various aspects, including the importance of fluoride toothpaste, caution against charcoal toothpaste, moderating sweets consumption, and the timing of teeth brushing. She asserts that dentists might be hesitant to share these secrets to avoid losing business. Newsweek spoke with dental professionals in the U.S. to evaluate the credibility of Manouchehri’s advice.
According to Manouchehri, using fluoride toothpaste twice daily and spitting without rinsing can strengthen teeth and even reverse early cavities. She dismisses charcoal toothpaste as abrasive, potentially wearing away tooth enamel. Houston-based dentist Fatima Khan supports the emphasis on fluoride, stating that it needs to be left on teeth for at least two minutes to be effective. Khan also warns about the abrasiveness of ingredients in whitening toothpaste, including activated charcoal.
Addressing sweets consumption, Manouchehri suggests reducing the frequency rather than the quantity of candy intake to prevent cavities. U.S.-based dentist Jarrett Manning agrees, explaining that continuous exposure to sugary foods throughout the day increases acid attacks on teeth, leading to potential cavities.
On the timing of teeth brushing, Manouchehri advises against brushing immediately after eating, allowing 30 to 60 minutes for acid created by food consumption to neutralize. Manning and Khan support this advice, highlighting the vulnerability of teeth to damage from brushing right after consuming acidic substances. They stress the importance of cleaning teeth at least 30 minutes after meals using floss, interdental brushes, or water flossers for comprehensive oral hygiene.
Both Manning and Khan endorse flossing as a crucial element in maintaining good oral health, breaking down bacteria colonies, and preventing plaque buildup. Manning specifically recommends traditional dental flossing as a professional recommendation.
As Manouchehri’s video gains traction with over 698,000 views, the dental community considers the value of her advice, emphasizing the need for evidence-based oral care practices.
