Maintaining optimal oral hygiene is crucial for healthy teeth and gums. Yet, one common question remains: Is an electric toothbrush better than a manual toothbrush?
As dental professionals, we often see patients struggle with choosing the right toothbrush. While both electric and manual toothbrushes can be effective, they have distinct advantages, disadvantages, and suitability for different individuals.
In this guide, we’ll explore the science behind electric and manual toothbrushes, what the research says, and what factors should influence your choice.
Electric vs. Manual Toothbrushes: Key Differences
Electric Toothbrushes: How They Work
Electric toothbrushes use oscillating, rotating, or sonic vibrations to remove plaque more efficiently than manual brushing. Some models even include pressure sensors, timers, and AI technology to help improve brushing technique.
Manual Toothbrushes: The Traditional Approach
A manual toothbrush relies on hand motion to clean teeth. When used correctly, it can be just as effective as an electric toothbrush, though it requires more effort to achieve the same results.
Which Toothbrush is More Effective? The Science Behind It
Research suggests that electric toothbrushes remove more plaque than manual ones, leading to lower rates of gum disease and cavities.
🔹 A 2019 study by the Oral Health Foundation found that electric toothbrush users had 22% less gum recession and 18% less tooth decay over 11 years compared to those using manual toothbrushes.
🔹 The Cochrane Review (2014), which analysed 56 studies, concluded that electric toothbrushes reduced plaque by 21% after three months, compared to manual toothbrushes.

While these studies suggest electric toothbrushes are superior in plaque removal, the technique used is equally important. A manual toothbrush, when used with the correct brushing technique, can still achieve excellent results.

What Do Dentists Recommend?
The NHS advises that both electric and manual toothbrushes can be effective if used correctly. However, many dentists recommend electric toothbrushes due to their improved plaque removal, ease of use, and additional features.
That said, manual toothbrushes remain a viable choice when used properly with the right brushing technique.
