Oscillating or sonic

Oral-B’s oscillating heads polish each tooth; Sonicare’s sonic heads sweep with high-speed vibrations. Both clean well, so pick the feel you like.

Running costs

What to skip

App coaching, color screens and charging cases are nice extras, but they do not clean better.

How to choose electric toothbrushes: the short version

Get a timer and pressure sensor, choose oscillating or sonic by feel, add up brush head costs, and skip premium models that only add screens and apps. This electric toothbrushes buying guide explains the features that matter, the ones you can ignore, and which models we would buy or skip.

Our shortlist: the Oral-B iO Series 5 ($99–$149) for best value premium clean. the Philips Sonicare 4100 Power Toothbrush ($39–$59) for budget. the Philips Sonicare ProtectiveClean 6500 ($79–$119) for sensitive gums.

How much should you spend on electric toothbrushes? Budget models start around $39, while premium options reach $299. Spending more usually buys the iO cleaning motor without the extras and sonic clean with a pressure sensor for under $60, but it is only worth it if you will use those features.

A pressure sensor protects gums and enamel from brushing too hard. A two-minute timer with 30-second pacing helps you brush evenly. Check brush head prices; they cost more than the handle over a few years.

Both clean well. Oral-B's round oscillating heads feel more like a dentist polish; Sonicare's sonic heads feel gentler. Pick the feel you prefer. Every three months, or sooner if the bristles splay.

Electric toothbrushes are heavily discounted on Prime Day and Black Friday. Buy brush heads in multipacks from official stores, because counterfeit heads are common.

Across the electric toothbrushes we cover, typical prices run from $39 to $299. Store prices change often, so treat these as typical ranges and check the current price before you buy.

At around $249–$299, the Oral-B iO Series 9 suits shoppers who want color screen, AI tracking and a charging case. Owners and specs point to charging travel case and color display, while very expensive is the catch.
