Whilst bamboo has natural antibacterial properties, it's not impenetrable like plastic, but if you help it to dry properly it'll last just as long as your old plastic toothbrush.

Once you've finished brushing your teeth, simply give it a quick rub with your towel then set it somewhere to dry. Lying on a flat surface is just fine as long as the water can drain away, but we recommend not to use a cup - any drips will collect in the bottom of the cup and build up every day, which is a little bit gross and won't do your brush any good over the weeks or months.
