チェックすべきポイント

A built-in pressure sensor is essential — most people brush too hard, which damages gums over time.

Oscillating-rotating (Oral-B) vs sonic (Philips Sonicare) — both are clinically proven; it comes down to preference.

Check replacement brush head prices before buying — ongoing costs vary significantly by brand.

Smart features and companion apps genuinely help improve brushing technique, not just marketing gimmicks.

よくある質問

Oral-B vs Philips Sonicare — which is better?

Both have strong clinical evidence. Oral-B's oscillating technology removes slightly more plaque in studies; Sonicare's sonic vibration feels gentler for sensitive gums.

How often should I replace the brush head?

Every 3 months, or when bristles are visibly frayed. Most brands include colour-fade indicators on bristles to signal when replacement is due.
