Bamboo toothbrushes:
Bamboo is a sustainable material that grows quickly with relatively few resources. Bamboo toothbrushes are typically biodegradable, but you have to check what the bristles are made from, ours are plant based.

Bamboo toothbrushes not only contain natural antibacterial properties, but they are also completely biodegradable. So you won't have to worry about polluting the environment as you use a bamboo toothbrush. They end up being decomposed within 3 to 6 months, while plastic toothbrushes take up to 500 years.

Plastic toothbrushes make for 1 per cent of the waste in the ocean. We are supposed to change toothbrushes every 3 to 4 months, which has a massive contribution to the overall plastic pollution in the world. Most plastic toothbrushes cannot be recycled due to mixed materials.
They also leech toxins into your body and microplastics into the water.
