Is a vibrating toothbrush effective?

Yes: It has the effect of loosening up plaque, so it may be more effective than a manual toothbrush. As with any toothbrush, consistency is the key, so make sure to use it regularly and diligently. And don't forget to floss!

Vibration is best!: Most baby boomers i encountered are mutilating themselves with aggressive toothbrushing. Brushing long, hard, with sweeping or circling motions are very archaic concepts and damaging! dental plaque has the texture of sugar mixed with butter. A slight vibration at the tooth /gum interface, one tooth at a time does the job. I spend about 1.5 min flossing, 1 min brush, 1 min brushing tongue.

Yes: Yes, a vibrating or ultrasonic toothbrush is not only more effective for cleaning your teeth but it's use is also great to improve the health of you gums.

Yes if used properly: Electric or vibrating toothbrushes can be very effective, but are not magic. They must be used properly in order to work. They will not clean any areas that they do not reach, so you must make sure to move them slowly and gently across all the surfaces of your teeth.
