Nano-b's charcoal and gold toothbrush is particularly useful for those looking to whiten their teeth in a natural way. It merges the antibacterial properties of gold with the natural whitening properties of bamboo charcoal. This brush is recommended for those with stained, discolored teeth and those looking for complete oral care protection combining health and beauty. Half the bristles are integrated with genuine gold nano-particles. These particles release negatively charged ions that penetrate bacterial cells, suppressing the cell's respiration and metabolism. The other half of the brush bristles are integrated with bamboo charcoal particles. Bamboo charcoal is a form of carbon, which is one of the best known natural teeth whiteners. Carbon removes acidic plaque from teeth, as well as stains commonly caused by drinking coffee and smoking.

Every brush has a double-layered bristle structure. The long, thin bristles clean deeply in hard to reach areas of the mouth, gently pushing the gums upwards to remove bacteria where it gets trapped, preventing common plaque buildup. The short, oval bristles polish the surface of the teeth, while protecting the soft tissue of your mouth from damage.

Nano-b uses a special manufacturing process that cuts its bristles in a way that rounds their edges. These rounded edges still perform greatly when it comes to cleaning, but they can't harm or damage your teeth and gums. Designed to be as attractive as they are effective, Nano-b toothbrushes are clean, smooth and transparent. They come in a range of crystal colors, have smooth handles and a beautifully nimble head. Each toothbrush comes with its own travel case, ideal for storage and travel.
