I received this question from a friend, and it got me thinking about toothbrushes again.
“I’m trying to buy some plastic free toothbrushes. Have come across a number of options. Just wondered if you had done any research on this that you may want to share. Also wondered if you could help me with the difference between “nylon -6” biodegradable bristles and “nylon – 4”. Sounds like a con to me as nylon and biodegradable is surely an oxymoron.”
I haven’t really thought about toothbrushes for some time, ever since I started using a Monte Bianco toothbrush that I bought about 6 years ago now. It’s not that I’ve been using the same toothbrush for that length of time, but it’s because the toothbrush has replaceable heads. Yes, the heads are still plastic, but I’m throwing away much less plastic every time as the full handle is kept and I just pop a new head on it, and it’s still working fine after 6 years. Even better, Monte Bianco have replacement heads that have either “natural” bristles made from boar hair or traditional nylon plastic. I’ve used both and they both work fine, the only difference is that the boar hair ones don’t seem to last as long as the nylon ones. Also, I don’t know how the boars are treated when they harvest their hairs, and that worries me too.
