Electric vs. Manual Toothbrush: Which Is Better for You?

It's one of the questions we hear most at checkups: should I switch to an electric toothbrush? The honest answer is that the best toothbrush is the one you use well, twice a day, for two full minutes. That said, electric brushes do have real advantages for many people.

What the research says

Studies comparing the two generally find that powered toothbrushes, especially the rotating-oscillating kind, remove somewhat more plaque and reduce gum inflammation a bit more than manual brushes over time. The difference isn't dramatic for someone with excellent technique, but most of us don't brush perfectly, and that's where electric brushes help.

Advantages of an electric toothbrush

• Does more of the work. The brush head moves for you, so you don't need perfect technique to clean well.
• Built-in timer. Many have a two-minute timer and a pulse every 30 seconds to move to the next part of your mouth.
• Pressure sensors. Brushing too hard wears enamel and pushes gums back. Many electric brushes warn you when you press too hard.
• Easier for limited dexterity. People with arthritis, other hand or shoulder problems, or limited mobility often find them much easier to use.
• Helpful with braces and aligners. They clean around brackets more efficiently.
• Kids often like them, which can make brushing less of a battle.

Advantages of a manual toothbrush

• Inexpensive and easy to replace
• No charging, which makes travel simple
• Effective when used correctly, with good technique and enough time
• Wide choice of sizes, handle shapes and bristle styles

Whichever you choose, pick soft bristles. Medium and hard bristles aren't more effective; they're harder on your gums and enamel.

How to brush well with either one

With a manual brush:

1. Hold the brush at a 45-degree angle to the gumline.
2. Use gentle, short strokes or small circles, one or two teeth at a time.
3. Clean the outer, inner and chewing surfaces of every tooth.
4. Spend about 30 seconds on each quarter of your mouth.

With an electric brush:

1. Guide the brush slowly from tooth to tooth and let it do the work. No scrubbing.
2. Hold the head against each tooth for a couple of seconds, angled toward the gumline.
3. Follow the timer through all four quarters of your mouth.

For both: use fluoride toothpaste, brush twice a day, and spit rather than rinse afterward so the fluoride keeps working. Brushing your tongue helps freshen breath, too.

When to replace your brush

Replace your toothbrush or brush head every three to four months, or sooner if the bristles are splayed. Frayed bristles don't clean well. It's also a good idea to replace it after a cold or other illness.

Don't forget between your teeth

No toothbrush, manual or electric, cleans between teeth well. That's where floss, interdental brushes or a water flosser come in, and skipping them is one of the main reasons gum disease develops.
