Key Benefits
  • Expands to clean between teeth more effectively.
  • Activated coconut charcoal helps lift plaque and impurities.
  • Supports healthy gums and fresher breath.
  • Flavoured with natural lemongrass oil.
  • Vegan and packaged in FSC-certified paperboard.

DrTung's Smart Floss® Activated Charcoal combines expanding floss technology with activated coconut charcoal to help remove plaque and clean effectively between teeth. The floss gently stretches to reach spaces that traditional floss may miss, supporting cleaner teeth and healthier gums as part of your daily oral care routine.

Activated coconut charcoal helps lift plaque and impurities, while natural lemongrass oil leaves a fresh, clean taste after every use. The soft, expanding fibres provide a thorough clean while remaining gentle on gums.

Packaged in FSC-certified paperboard, this vegan floss is free from genetically modified ingredients, known allergens, phthalates, soy, silica, dairy and gluten. It offers an effective, more environmentally conscious choice for everyday oral hygiene.
Why DrTung's is Healf
Smart Floss® Activated Charcoal combines an expanding floss design with activated charcoal to help lift more plaque and bacteria during daily cleaning. As the floss moves between teeth, it expands to create a larger cleaning surface, helping remove up to 55% more plaque than common dental floss types. Activated charcoal adds extra adsorption support, while a proprietary vegetable wax blend helps the floss glide smoothly without shredding or pulling. The formula uses vegan ingredients, involves no animal testing, and contains no PFAS, PTFE or BPA. FSC-certified packaging also supports a more responsible oral care choice, helping you clean between teeth more effectively while keeping the routine simple and conscious.

DrTung’s, founded in Hawaii in 1997 by Colin Davis, was built on the belief that oral health plays a vital role in overall wellbeing. The brand combines ancient Ayurvedic wisdom with modern dental science, beginning with America’s first commercially available tongue cleaner. Its range includes biocompatible oral care products designed to support the mouth’s natural microbiome, from tongue cleaners to clinically tested Smart Floss. DrTung’s avoids parabens, artificial flavours, sweeteners, and forever chemicals, focusing instead on safer, effective ingredients. With DrTung’s, you can care for your mouth in a cleaner, more natural way every day.
