My father in law has a pacemaker and they can get information from him as well. I could see how that might be beneficial for the tooth brush. The sad thing is the people who can afford that technology often aren't the ones that actually need it. I mean, if I am spending $100 for a toothbrush, there is probably a pretty good chance I take really good care of my teeth to begin with. Not sure where I am going with that... just something that I realized.
