Dentists usually recommend that toothbrushes are replaced every 3 months. Average life expectancy in the UK is 80 years old which means over our lifetime, we use and throw away roughly 320 toothbrushes each. Worldwide, that is a massive amount of toothbrushes all ending up in landfill! 

Bamboo is considered to be a sustainable resource because it is fast growing so reproduces quickly, and is completely biodegradable. The handle of the toothbrush makes up the majority of the product so this eradicates a large amount of plastic just by making the handle out of this resource which is a step in the right direction!

Most plastic toothbrushes can be found very cheaply - usually you can find a family pack of 4 in supermarkets for £1, although you can buy the branded ones for anything up to £3/£4.  So in comparison, bamboo toothbrushes are quite a bit pricier. Whether you deem it to be worth the extra price or not is down to personal preference. It keeps me up at night, the idea of (7.8 million global population x 320 toothbrushes - whatever huge number that comes out as) being thrown in landfill and left there for 1,000 years so for me, these are totally worth the additional expense.
