Oral-B iO Series 3 Vs Dyson CameraJet

The Oral-B iO Series 3 is oscillating-rotating. The Dyson CameraJet is sonic + camera jet. That changes how each one feels in the mouth. Oral-B iO Series 3: Oscillating-rotating, Oral-B does not publish a strokes-per-minute figure for iO the way it does for the older 3D line. Magnetic iO drive: oscillating-rotating round head plus micro-vibrations Dyson CameraJet: Sonic + camera jet, 245 oscillations per second, which is 14,700 per minute. Dyson describes the rate as variable so the bristles do not stall.. Variable sonic oscillation plus a camera-guided conical liquid jet that fires at gaps while you brush. Dyson's first toothbrush, launched 1 September 2026. A round oscillating head is a tooth-by-tooth scrub. A sonic head is a sweep, and the fluid it throws is part of the clean. A jet or a water flosser is a third job. Do not score those as if they were the same machine.

Neither has a clear edge here. Compare the gentle modes below. Oral-B iO Series 3: Sensitive mode plus a visible pressure ring. No Super Sensitive mode on the Series 3. Dyson CameraJet: Gentle intensity and a softer head option. The jet is a new sensation. Start on Gentle, auto-jet off, until the angle makes sense. Dentists who talk about recession in public usually point at a sonic brush before a round oscillating one, because the sweep feels less sharp on exposed roots. That is a feel call, not a license to skip the pressure sensor. If a brush has no sensor, technique is the whole safety system.

The Dyson CameraJet has water flossing built in, which helps the gumline under the wire. Oral-B iO Series 3: Round head reaches around brackets better than a long sonic head for many people. Confirm the head your orthodontist wants. Dyson CameraJet: Not a verified braces brush. The jet and the camera are aimed at gaps between teeth, not at brackets. Ask your orthodontist before you aim a jet at hardware. Round heads reach the tooth face around a bracket more easily for a lot of people. Long sonic heads cover more enamel per second and bump the wire more often. A built-in flosser helps the gumline under the wire, which a brush alone does not. None of these replace the conversation with your orthodontist. Ask before you aim a jet at hardware.

Both warn you when you press too hard. How they warn you is the difference. Oral-B iO Series 3: Visible 360-degree ring: green just right, red too hard and the brush slows, white too soft Dyson CameraJet: Onboard pressure and overscrubbing sensors with haptic and LED alerts. Also flags section changes and technique. A hidden sensor that only cuts the pulsations is easy to miss. A light ring you can see in a mirror is the one people actually change behavior for. Adaptive systems that turn the motor down are a step past a warning. No sensor at all means the brush will happily let you scrub a groove into the gum.

The Oral-B iO Series 3 has the longer published runtime: 14 days against 10. Oral-B iO Series 3: 14 days. About 2 weeks at two 2-minute sessions a day. Oral-B lists a longer window on some bundles. Lithium-ion, magnetic charger. Dyson CameraJet: 10 days. Swappable lithium-ion. Up to 10 days, or about 14 complete cleans, on Gentle with one Brush + Auto-jet session a day. About 8 hours to charge by USB-C pogo cable or the dock. Replacement battery $59.99. Runtime assumes two minutes, twice a day, on a gentler mode. Whitening modes, radios, and jets spend it faster. A NiMH pack that wants an overnight charge is a different product from a lithium handle that is full before dinner.

No. The heads do not cross, so refills you already own may not fit. Oral-B iO Series 3: Round, cups one tooth. iO heads only. Not compatible with Pro, Smart, or Genius heads. About $8 a head. Genuine iO heads run about $8 to $10 each, often $30 to $40 for a 4-pack before sales. Replace about every 3 months. Dyson CameraJet: Dual-bristle head: firmer inner bristles, softer outer, silicone back. RFID wear tracking. Two heads in the set. Not compatible with any other brand. Sensitive head sold separately. About $15 a head. Replacement heads about $30 a pair, so about $15 each, every 3 months. RFID tells you when. Optional Dyson toothpaste and rinse exist because foam can block the camera. SLS-free, low-foam paste is what Dyson asks for. The American Dental Association tells people to change a brush about every three months, or sooner if the bristles splay. Four heads a year is the math we use. A subscription only helps if you were going to buy that brand's head anyway.
