The Best Electric Toothbrush (After 90 Days of Plaque Logging)
Five electric toothbrushes, three months, and a dental hygienist who agreed to score plaque levels for us. The pricier ones don't always win.
The right electric toothbrush is the one with a real pressure sensor and reasonable replacement-head economics.
+ What we liked
- ✓Pressure sensor that actually triggers (others ignore the threshold)
- ✓Brush head replacements available without subscription
- ✓Battery lasts three weeks on one charge
− What could be better
- !App is unnecessary
- !Charger uses a non-standard travel-unfriendly base
Electric toothbrushes are a category where the marketing is much louder than the science. After three months and five toothbrushes, with plaque scoring done by a dental hygienist friend, here's our pick.
Our pick
A mid-priced sonic toothbrush with a real pressure sensor (it cuts power when you press too hard, vs. the toy-grade vibration warnings on cheaper models), brush heads available at any pharmacy, and a battery that lasts three weeks. Plaque-score reduction over our 90-day test was within 4% of the flagship at half the price.
The bottom line
Get a sonic toothbrush with a pressure sensor and easily-available replacement heads. Don't overspend on the flagship — the marginal benefit is small and the replacement-head economics on premium brushes are punishing.

Six weeks of daily use here. Echoing the review — the build quality is genuinely good. One thing I'd add: the customer service was responsive when I needed a replacement part.

Came for the data; staying for the writing. Thanks for taking the time to do this right.

How does this compare to the older model from two years ago? Mine is still going strong and I'd hate to upgrade if it's a sidegrade.

Bought a used one off Marketplace based on this review. Working great, half the price.

Curious about your noise measurement methodology. dB readings vary a lot with mic placement.
