Who saiys that, nearly every dentist I have spoken too all say to use electric. Manual doesnt even come close.
Every dentist I've ever visited. Last one was in Mexico, the one before that in Spain, before that in greece, and before that my usual one in the UK. It's probably something to do with their training. Normally they say electric is better when people don't know how to brush their teeth properly with a manual brush.
I much prefer an electric brush though.
