With their combined expertise as a hospital doctor and a buyer they designed a toothbrush which is not only healthy and practical to use, but looks great in the home too. Catherine and Catherine chose bamboo as the material for their Truthbrush handle as it is beautiful to look at, warm to touch and is also fully biodegradable. With its natural antibacterial and antifungal properties bamboo is hygienic for use in the bathroom too. The bamboo used is Moso bamboo which is grown organically in China. To add a splash of colour the bamboo handle is dipped in an eco-friendly, water-based paint.The bristles on the Truthbrush are made from a blend of 62% castor bean oil (a renewable vegetable oil) and 38% nylon. To dispose of your toothbrush, please place in your ordinary bin. Over time, all but the bristles will biodegrade, leaving no residue.Alternatively, you can pull out the bristles with a pair of pliers and re-use the Truthbrush in any creative way you can. Plant canes and paint stirrers are just a couple of examples of how you can give your Truthbrush a second life.All of the adult Truthbrushes we sell have medium white bristles. The Tiny Truthbrush has soft transparent bristles. The interdental brushes have 100% BPA-free nylon bristles (castor oil bristles are not commercially available in this size).The Truthbrushes are carefully wrapped in tissue paper and a fully recyclable pillow pack with a colour reference at each end. They have passed the ISO 20126:2012 safety and performance test.Also available is a Truthbrush bamboo travel case made of natural polished bamboo, with an engraved Truthbrush logo, and ventilation holes to allow the brush to dry out between uses. Most dental professionals recommend changing your toothbrush every 3 months.
