“Which electric toothbrush is best for gingivitis?”

I prefer the sonic technology brushes.  These devices use ultrasonic vibrations to remove plaque.  The soundwaves actually reach beyond the bristles to burst open bacterial cell walls.  Watch the tutorials on Youtube.  The technique for brushing is entirely different than brushing with a manual brush.  Hope this helps.  Mary Swift, DDSDallas Laser Dentistrywww.dallascosmeticdentist.us

I prefer the Oral B but Sonicare has its fans also
