Electric toothbrushes tend to remove more plaque and reduce gum inflammation more than manual brushes, according to research reviews, mainly because they do much of the work for you. But a manual toothbrush used with good technique for two full minutes, twice a day, keeps teeth and gums healthy too. The best toothbrush is the one you use properly and consistently.

Who benefits most from an electric toothbrush?
- People with braces
- People with limited hand movement or arthritis
- Children who find brushing boring
- Anyone who tends to brush too quickly or too hard
- People with gum disease who need extra plaque control
How to brush properly (either type)
- Use a soft-bristled brush and a pea-sized amount of fluoride toothpaste.
- Angle bristles at 45 degrees towards the gumline.
- With a manual brush, use gentle small circles; with an electric brush, guide it slowly tooth by tooth and let it do the scrubbing.
- Brush all surfaces: outside, inside and chewing surfaces.
- Brush for two full minutes, twice a day.
- Spit, don’t rinse, to leave fluoride on your teeth.
How often should you replace your toothbrush?
Every three months, or sooner if the bristles are splayed. Also replace it after a cold or flu. Worn bristles clean far less effectively.
Frequently asked questions
Do I need an expensive electric toothbrush? No. Basic rechargeable models with a timer clean well. Premium features are nice extras, not essentials.
Oscillating or sonic: which is better? Both types clean well. Pick the one you find comfortable.
Can electric toothbrushes damage gums? Not when used gently. Pressing too hard with any brush can wear gums, so a pressure sensor helps.
