Why the iO Series 5 Is Our Top Pick
When we recommend an electric toothbrush, we look for the model that delivers the most meaningful features at a price most people can justify. The Oral-B iO Series 5 wins that calculation decisively. At $119, it sits at the intersection where you get everything that actually matters for dental health — the iO magnetic drive, adequate cleaning modes, pressure monitoring, and app tracking — without paying for premium extras like color OLED displays and AI 3D mapping that, while impressive, do not fundamentally improve how clean your teeth get.
The core cleaning technology in the Series 5 is identical to the $299 Series 9 and $379 Series 10. The same linear magnetic drive. The same oscillating-rotating action. The same energy transfer to the bristle tips. When it comes to plaque removal — the primary job of any toothbrush — there is no difference between the entry and flagship models. This is important to understand: you are not getting a worse clean with the Series 5. You are getting fewer luxury features.
Five Cleaning Modes Explained
The Series 5 includes five modes, each designed for different situations:
- Daily Clean — The go-to mode for everyday brushing. Balanced speed and pressure for thorough plaque removal.
- Intense Clean — Higher intensity for those times when you want a deeper clean, such as after eating sticky or sugary foods.
- Whiten — A polishing mode with varied speed patterns designed to gently remove surface stains over time.
- Sensitive — Reduced intensity for tender gums or post-dental work recovery.
- Super Sensitive — The gentlest mode, ideal for people with significant gum sensitivity or those new to electric toothbrushes.
Five modes is the sweet spot. The Series 9 adds Tongue Cleaning and a dedicated Gum Care mode, but realistically, most people rotate between Daily Clean, Sensitive, and Whiten. Having Intense Clean available for occasional deep sessions is a nice bonus that you do not get with the three-mode Series 3.
LED Display and App
The LED display on the Series 5 is modest compared to the OLED screens on the Series 7-10, but it serves its purpose. It shows your current cleaning mode using simple icons and provides pressure feedback through color-coded LED indicators (green for good, red for too hard). You can see the mode at a glance while brushing, which is more than the Series 3 offers.
The Oral-B app, connected via Bluetooth, is where the Series 5 really steps up from cheaper models. The app tracks every brushing session, monitoring duration, coverage, and pressure. It provides a brushing score after each session and shows trends over time. For people who are motivated by data and want to improve their oral hygiene habits, this feedback loop is genuinely useful. You can also set brushing goals, get reminders to replace your brush head, and customize your routine.
Battery Life
The Series 5 delivers approximately 10 days of battery life with twice-daily 2-minute sessions, which is a meaningful improvement over the 7-day battery in the Series 2 and Series 3. In practical terms, this means you can comfortably go through a work week and weekend without charging, and even stretch to two weeks with lighter use. The magnetic charger takes about 3 hours for a full charge.
