Nano toothbrush, brush your teeth once a day.

Brushing teeth only once a day? How unhygienic! However, researchers from a Japanese company claim: "You can with our toothbrush!"

According to the researchers, the bristles of this toothbrush are coated with a hydrophilic nanomaterial at their tips. When brushing with this toothbrush, the hydrophilic nanomaterial adheres to the surface of the teeth, keeping them moist all the time and making it difficult for fine residues and microorganisms to stick to the tooth surface.

Thus, brushing your teeth once a day with this toothbrush is sufficient. Less toothpaste is used, less water is used, personal waste discharge is reduced, truly low-carbon.
