The Best Electric Toothbrushes for 2026
A good electric toothbrush is one of the few genuine upgrades you can make to your daily routine, clearing more plaque than manual brushing and nudging you to actually stick to the full two minutes. But the market runs from £40 workhorses to £300 app-connected flagships, and price does not always track performance. Below we rank the five best electric toothbrushes that earn their place on merit, whatever your budget or priorities.

Frequently asked questions
Are electric toothbrushes better than manual toothbrushes?
The evidence generally favours electric brushes: reviews of clinical studies have found that powered brushes, particularly oscillating-rotating types, remove more plaque and reduce gum inflammation than manual brushing over time. Just as important, the built-in two-minute timer and pressure sensor help you brush for long enough without scrubbing too hard, which is where most people go wrong.
Which is better, an oscillating or sonic electric toothbrush?
Both clean well, so it often comes down to feel. Oral-B's small round heads oscillate and rotate, giving a scrubbed, tooth-by-tooth sensation many find thorough. Philips' sonic brushes vibrate a longer head at high frequency, which tends to feel gentler and suits sensitive gums. If you can, try a friend's, or start with a budget model of each type to see which you prefer.
How often should you replace an electric toothbrush head?
Roughly every three months, or sooner if the bristles are visibly splayed. Worn bristles clean far less effectively and can be harsher on your gums. Some brushes include a reminder feature, but a simple rule of thumb is to swap heads at the change of each season. Factor the ongoing cost of replacement heads into your buying decision, as it varies a lot between brands.
Is it worth buying an expensive electric toothbrush?
For most people, no. The features that genuinely protect your teeth, effective cleaning, a two-minute timer and a pressure sensor, are available on mid-range models costing far less than the flagships. App tracking can help for a few weeks while you improve your technique, but most users switch it off. Buy the connected models only when they're heavily discounted.
