It may be just fine for you. Not everyone has my needs. Gums seem to have been
my body's weak spot.
To be clear, though, Sonicare and the other major brand (OralB?) are strictly
sonic, ie, low frequency, not ultrasonic,
so they will have no effect on bacterial colonies below the gum line where the
bristles can't reach. It's ultrasonic
waves transmitted through saliva and along the surface layers of the gum tissue
that do that work.
