Toothpaste is a staple in oral hygiene routines around the world. But dental experts are challenging its necessity, highlighting alternatives that deliver real results.
Toothpaste supports oral hygiene by removing plaque, freshening breath, and helping prevent issues like gingivitis. Yet, as noted in New Scientist on July 7, 2021, three dental professionals question its must-have status.
Oregon dentist Stephen Johnson explains that not all toothpastes contain fluoride, the mineral key to remineralizing enamel. Without it, benefits come from abrasives that lift stains, surfactants that break down bacterial biofilms, whitening agents, texture enhancers, and flavors for breath freshening. For those needing fluoride, professional varnishes or prescription high-fluoride toothpastes are effective options.
Dutch dentist Tom Smits from Zandvoort emphasizes the toothbrush as the real hero. Beyond fluoride, toothpaste mainly adds flavor. Harmful bacteria lurk at least two millimeters deep, reachable primarily by thorough brushing.
Belgian dentist Geert Catteeuw from Roosdaal, who wears full dentures, hasn't used toothpaste in about ten years. He brushes with a stiff-bristled brush and water for teeth, switching to soft bristles for gums. Though more time-intensive, it avoids toothpaste runoff into sewers.
Like some skincare products, toothpaste contributes to waterway pollution. A 2015 University of Plymouth study warns that these formulations often overlook environmental impacts.
