Choose from two sizes: Adult / Child100% organic bamboo handles! Plastic cannot biodegrade, and every single bit of plastic ever made still exists in some form today. Conventional plastic toothbrushes use a significant amount of unnecessary plastic that these bamboo toothbrushes can easily help to avoid.Caring for your toothbrush Just like bamboo straws, bamboo toothbrushes should be kept in a dry area and not in enclosed toothbrush containers or cups that collect water. With proper care, your bamboo toothbrush will last as long as a regular plastic toothbrush. Dentists recommend replacing your toothbrush at least once every 3 months or when their bristles have frayed.Disposal or repurposing The bristles of our brush are nylon. They can be easily removed from the brush handle when you are ready to retire your brush. The bamboo handle can be composted or reused -- it is a pretty lovely piece of bamboo! Get creative and use it as a tag around the home or for your planter pots.
