Check out this marvel of modern science (but ignore the tacky counters in our bathroom). My new toothbrush rocks. Just look at that comfort gel grip...so squishy. Note the ergonomic shape of the handle (to prevent carpal tunnel). Observe the round things in the bristles. They work miracles. And what you don't see is that on the back of the head is a textured soft thing that makes your mouth happy when you brush.
I'm telling you, if everyone had a toothbrush like this people would only ever see dentists if they were masochists.
