What the best electric toothbrush to massage gums?
Philips Sonicare is a brilliant product. I've been using it for a few years and recommend it to all my friends!
What I mean is I want a electric toothbrush which will brush my gums in a space between my molars.I want a brush just doesn't just actually rotates, pulsates and oscillates effectively on gums.
I mean I just a electric toothbrush which occilates, rotates and pulstates in a large gap between two molars.
