Electric or Manual Toothbrush? What the Research Says About Brushing Smarter
Is an electric toothbrush worth it? A Cochrane review of 56 trials found powered brushes reduced plaque by 11% to 21% and gingivitis by 6% to 11% compared with manual brushes. Whichever you use, technique matters: brush two minutes twice daily with a soft brush, angle the bristles toward the gumline, use light pressure, and replace your brush or brush head every 3 to 4 months.
