After a long search I’ve settled on a good toothbrush. We’ve tried wooden ones with natural bristles; awkwardly shaped. We’ve tried plastic toothbrushes with removable heads and natural bristles; the bristles fell out. We’ve tried another removable-top version with plastic bristles; still so much plastic. Then I came across another possibility.
These are bamboo handled toothbrushes, quite beautiful I think. They’re shaped well, and don’t seem to turn grey in the water as wood does. Even the bristles are a biodegradable nylon, so they are compostable. A fair companion to our homemade toothpaste. They age well too, and so they’ll be retired in a few months to the cleaning trug, to live out life in service, in the company of the feather duster, the cotton mop, the sodium bicarbonate and the vinegar. Have a look around for bamboo toothbrushes, see what you think.
