yes, they just clean better than an toothbrush from last century.
My dentist also says my teeth are better than before the sonicare.
So it saved me many appointments by the dentist.
Here in Brazil there aren't many electric toothbrush.
I saw one Philips store and they had everthing, except the sonicare teethbrush
When south america starts brushing electric, Philips will get a huge extra profit.
I think here maybe 5% use electric while in Holland at least 80%
