Naturborsten produce an eco-friendly wooden toothbrush with natural bristles. The brush is made from sustainably harvested wood (beechwood) and is then preserved using linseed oil. The bristles are made from all natural, sustainably sourced produce; pig hair. The bristles can seem a little hard the first time you use them but they soften quickly when wet. Plastic toothbrushes can take their toll on the environment, if they are replaced 3-4 times a year all the plastic can add up. Naturborsten all natural toothbrushes are made from all sustainable products and is also perfect for looking after healthy teeth and gums.
