I still don't understand why this has to be custom fit to your mouth/teeth, since every part of brushing is handled by the bristles, why does it matter if it is formed perfect for your teeth? I imagine, like most other products, this could be sized up to a small, medium, or large, or even have a brush that could be trimmed off (with scissors, like a mouthguard, for instance).
