Electric vs manual toothbrush: what the evidence says
Clinical trials consistently show electric brushes remove more plaque. But the best brush is the one you'll actually use.
A 2019 Cochrane Review, the gold standard in clinical evidence, found that electric toothbrushes remove 21% more plaque and reduce gingivitis by 11% more than manual brushes after three months of use.
Why electric wins on numbers
Oscillating-rotating heads (like Oral-B round heads) produce thousands of micro-movements per minute that manual brushing simply can't replicate. The round head design also physically adapts to the curve of each tooth.
But technique still matters
A poorly-used electric brush won't outperform a well-used manual one. The key is letting the brush do the work: guide it slowly around each tooth rather than scrubbing with it.
When manual is fine
For patients with good technique and no specific issues, a quality manual brush is perfectly adequate. Children often do well with manual brushes because the learning of the technique is valuable.
Our recommendation
If you're upgrading, an entry-level oscillating electric brush from a reputable brand makes a meaningful difference. Replacement heads every 3 months are non-negotiable.
