Since Egyptian times - we have become more and more accustomed to looking after our "pearly whites".
However, we have come a long way from chew sticks and although fashion has moved a lot of us from manual toothbrushes to electric with changeable heads - the quantity of toothbrushes that are thrown away each year is staggering. In the USA alone a billion toothbrushes are discarded each year. On the basis that a lot of plastics find there way into seas and oceans around the world this is a situation that cannot be allowed to continue.
One option that you could consider is swapping to bamboo toothbrushes. While the handle of a natural bamboo toothbrush is biodegradable, the bristles themselves are probably not. After reusing the toothbrush for cleaning tools/gadgets/car wheels (or other inaccessible areas) the bristles should be removed using pliers and placed into your plastic recycling bin.
In spite of the fact that this is not an ideal situation, it is immensely better than the current waste of throw away toothbrushes and the remaining handle could be used as a plant identifier in the garden or other reusable method.
