Sonic toothbrushes use a fast side-to-side vibration rather than the rotating round head Oral-B uses. Philips Sonicare dominates this category, with a range that runs from the ProtectiveClean 6100 to the Next-Generation DiamondClean 9900 Prestige, and Waterpik adds a sonic brush with a built-in water flosser. This guide compares eight sonic brushes on the specs the listings actually give: bristle movements per minute, number of modes, intensity levels, battery life, how they charge and whether they connect to an app. Many listings skip the movements figure or battery days, so we mark those as not stated rather than fill the gaps. Use the modes and charging columns to narrow things down, then check which heads come in the box.

The products in detail
No. 1 · PHILIPS
Sonicare Next-Gen 9900 Prestige: SenseIQ, 8 modes, display
The Next-Gen 9900 Prestige combines SenseIQ intensity control, 3 intensity levels and green-light pressure feedback on the handle. Suits anyone wanting the most control.
In its favour
- SenseIQ adapts the intensity to your brushing style, according to Philips, with pressure feedback that glows green when pressure is right.
- Coverage feedback glows blue for finished areas, and the handle display shows post-brushing feedback on spots you missed.
- The box includes a Prestige charging travel case plus a charging base and glass, so home and away charging are both covered.
Good to know
- Only one A3 All-in-One brush head comes in the box, so you will need to buy spares sooner than with multi-head sets.
- The listing gives no battery life figure in days, which matters if you plan to rely on the travel case for long trips.

No. 2 · PHILIPS

No. 5 · PHILIPS
