Our mouths are small. Our teeth are small. Yet most toothbrushes are made big. You may say, “Mine is not big, it’s the regular size.” But actually, the regular size is “regular” as decided by the manufacturer. It’s very likely that it is still big for your mouth.

Bottom: the MUJI toothbrush
The MUJI toothbrush is small. When you use it, you feel like you are brushing your teeth one by one, because the head is about the same size as a single tooth. You brushing one tooth, then the space between the teeth, and then the next tooth, and then under the gum line. If using a regular toothbrush is like driving a car, using a MUJI toothbrush is like riding a bike. When you ride a bike, you can feel the crisp air, see the flowers by the roadside, and feel your muscles working. By the same token, you will discover subtle details about your mouth, such as how your teeth line up and the contours of the gaps.
In addition, the filaments of MUJI bristles are soft and elastic. You will brush much more slowly and more carefully as you move over your teeth, and that is a better way to clean them. The toothbrushes come in two styles: the “super thin” has the end of bristles tapering off, and the “regular” has an even bristle width. The latter feels a bit firmer. You can choose the one you prefer based on your needs.

Although it’s not advertised, it is likely that these products were designed by Naoto Fukasawa, since he lists the MUJI toothbrush as his work in his book “デザインの輪郭 (The Profiles of Design)”. They do seem to reflect his concept of “anonymous” beauty.
