These Interdental Brushes from Hydrophil feature a plastic-free bamboo handle, and are an environmentally friendly complement to your daily dental care. They allow you to clean the hard-to-get-at spaces between your teeth for yourself. Using the Interdental Brush together with the Hydrophil Bamboo Toothbrush means you not only protect your teeth and gums, but at the same time you protect the environment. How to usePush the Interdental Brush carefully into the space between two teeth. Move the brush horizontally back and forth a few times as well as diagonally in an “X” movement alongside the teeth. Do this carefully. Always use the Interdental Brush without toothpaste, and preferably daily before brushing your teeth. Clean the brush under running water. You should replace the brush after 7 to 14 days. DisposalAfter use, the HYDROPHIL Interdental Brushes should be disposed of in the residual waste. Unfortunately, for reasons of hygiene, it is not yet possible to dispose of the bamboo handle as organic waste.
