Switching from a plastic toothbrush to a bamboo or beechwood toothbrush is probably the easiest eco-friendly change someone can make. Dentists recommend that you should replace your toothbrush every 3 months. This means that approximately 265.6 million toothbrushes are disposed of every year within the UK. The majority ending up in landfill or in the ocean. Natural and plastic free toothbrushes will help protect the ocean and still leave your teeth and mouth clean and fresh.
