With some consumer products we see constant change. Computers and cars, for instance, are constantly being improved with the discovery of new technical advances. What about the toothbrush – which has been with us for many years? It turns out that this field of invention is very much alive, as illustrated by this very interesting article.
What toothbrush inventors tell us is that the world of the toothbrush has need for much improvement – so the changes keep coming. The reason for this is that brushing your teeth effectively is actually quite complex. Your mouth isn’t flat like a kitchen floor so you can clean it with a simple brush. Parts of your mouth are hard to get to – you can’t see what your doing – the space in between your teeth is particularly difficult to clean (and requires a different tool than you might use for the outside surface of the teeth). The list goes on.
Some of the innovations in the works are sensors that adapt electric toothbrushes to different surfaces in the mouth, improved brush bristle angles to improve cleaning, and cosmetic changes to make the tooth brush more appealing to use.
