Do you need the brush to do more than remove plaque.... not really. It's like anything else, people choose what is most comfortable for them to use.

I have an answer for the timing thing. I brought my timer into the bathroom. I set it to 3 minutes (just to see if it went over). I did the brushing, and the thing beeped every 30 seconds, then it went to 4 long beeps and gave me a smiley face.
How long???
2 minutes exactly.
So now we know!!!
