Sonicare 5500 vs Oral‑B iO5: which mid-range electric toothbrush is better?
Two capable brushes, two completely different sensations. Here is how I would choose between them—and why I personally use Sonicare.
Reviewed 9 September 2026 · Ireland edition
At this level, there is no obviously poor choice. Both brushes have a two-minute timer, pacing prompts and pressure feedback—the features that matter far more than a long menu of novelty modes. The real decision is whether you prefer Sonicare’s slim, familiar-shaped head and sweeping sonic action, or Oral‑B’s small round head and more guided, tooth-by-tooth feel.

What they feel like in the mouth
Sonicare
Sweeping and familiar
The Sonicare head resembles a compact manual toothbrush. You guide it slowly along the gumline and let the bristles do the work. The vibration can feel ticklish at first, but many people find the overall sensation smooth once they stop scrubbing and lighten their grip.
Oral‑B iO
Focused and tooth by tooth
The iO head cups a smaller area, which makes it intuitive to pause briefly on each tooth. The movement feels more concentrated. Some people love that polished sensation; others find the larger round head or stronger mechanical feel less comfortable.
Pressure control: Oral‑B communicates more
Both models address one of the most common electric-brushing mistakes: pushing too hard. Sonicare’s feedback is deliberately restrained—it alerts you and reduces power. The iO5’s illuminated ring is harder to miss and distinguishes between too much, too little and suitable pressure. If you know that you scrub aggressively, the Oral‑B system may be the more useful teacher.
Modes and app features
The Sonicare 5500 has two modes: Clean and White. That is enough for most people, and I prefer its lack of distraction. The iO5 offers five modes and connects to the Oral‑B app for brushing feedback. The app can help someone who enjoys measurable guidance, but it only adds value if you will actually open it after the novelty wears off.
Neither “whitening” mode changes the intrinsic colour of teeth. At most, a toothbrush and appropriate toothpaste can help reduce external surface stain. Bleaching or managing deeper discolouration is a separate dental decision.
Brush heads and ongoing cost
Do not compare handles without checking replacement heads. Sonicare’s click-on system offers several genuine head shapes, while the iO range uses its own round iO heads rather than older Oral‑B heads. Prices vary frequently, so check the cost of a genuine multi-pack before choosing. A brush you can afford to re-head regularly is a better purchase than a premium handle fitted with worn bristles.
