I don't actually recommend this.

Nothing better exists yet, or I haven't found it. If you know of something better, send it to me.

Why it's here

Revised Mar 2026

It cleans well. The pressure sensor is genuinely useful and stopped me brushing too hard, which my dentist noticed. That's the entire list of good things.

Everything else about it is a mess. There's a screen on a toothbrush. There's an app that wants to gamify brushing my teeth. The charging base is proprietary. Replacement heads are priced like printer ink and the brush nags you to replace them early.

I'd genuinely love to be talked out of this one. If there's a quiet, well-built electric toothbrush with a pressure sensor, reasonable replacement heads and no screen, I want to know about it.

The honest list

What works

2
  1. Pressure sensor that actually changed how I brush
  2. Quieter than the older oscillating models

What I'd change

4
  1. There is a screen on it, for no reason
  2. The app is gamified nonsense I've never opened twice
  3. Replacement heads are priced like printer ink
  4. Proprietary charger — one more cable that does one thing

§4 · Challenge the pick

This slot is unsolved. Help.

I'm using this because nothing better exists, or because I haven't found it yet. If you know of something better, this is the single most useful thing you can send me.
