Key features & specs

How it compares

Compared to standard sonic brushes like the Philips Sonicare, the Oral-B iO Series 5 uses a round oscillating head that many users find more effective at cleaning between teeth. Its pressure sensor provides a distinct advantage for gum care, reducing the risk of over-brushing. In contrast, cheaper electric toothbrushes often lack any pressure feedback, making the iO Series 5 a safer choice for sensitive gums.

What to know before buying

1. The iO Series 5 includes a pressure sensor that glows red when brushing too hard—ideal for gum care.
2. Charge the handle for 16 hours before first use; a 3-minute quick charge is enough for one brushing session.
3. Pair with the Oral-B app to track brushing coverage and length, which can help improve gum health.
4. Replace the brush head every three months, or sooner if bristles fray.
5. Use the ‘Sensitive’ or ‘Super Sensitive’ mode for the gentlest clean on tender gums.
6. Keep the charging base clean and dry to prevent buildup.

"The pressure sensor has completely changed how I brush—I didn’t realize how hard I was pressing. My gums have stopped bleeding and feel much less tender." — Verified buyer

Sustainability & ethics

The handle is made of recyclable ABS plastic, and the packaging is largely recyclable cardboard. Oral-B has a partnership with TerraCycle to recycle used brush heads and battery packs. The brand is cruelty-free, and some parts are sourced from Europe. However, the product is assembled in Germany, which reduces some transport emissions.
