As a result of the recent research that has been done on the effects of plastic, a lot of people are looking for an alternative to the traditional toothbrush. Many are turning to a bamboo toothbrush. Bamboo is a sustainable and eco-friendly resource that is both durable and biodegradable. A bamboo toothbrush is soft on the teeth and the bristles are biodegradable, which is better for the environment. They are also great for sensitive teeth.
