Charcoal toothbrushes are a popular option in dental health, especially for their ability to reduce bacteria and improve oral hygiene. The bristles are reinforced with activated charcoal, which has absorbent properties and helps to remove more plaque and reduce bacterial growth. The handle is made of cellulose acetate, a material that absorbs little moisture, which reduces bacterial growth. The toothbrush undergoes hand polishing for a smooth and comfortable finish. Handmade in Milan, Italy.
