I just purchased the Sonic toothbrush. My dentist recommended it for me because I am killing me gums. I brush too hard and with this new brush it is impossible to do. The brush shuts off when I put too much pressure on my teeth and gums. It also claims to whiten teeth with out all those messy products that make your teeth sensitive. So far I think it was worth the money.
