It’s important to note that all Oral-B electric toothbrushes adhere to a strict consumer health data privacy policy.

Detailed Differences between Oral-B iO Series 4 vs 5?

Comparing brush heads and cleaning modes

The Oral-B iO4 and 5 use the same iO-specific brush heads, which are designed to work with the unique magnetic motor in the iO Series toothbrushes. These brush heads are slightly deeper than traditional Oral-B brush heads, but they are still compatible with most mouths.

And in terms of modes, the iO 5 has one additional brushing mode, “Intense,” which is designed for stubborn plaque. Both models have a Daily Clean mode, a Sensitive mode for those with sore gums, and a Whitening mode. The iO 4 also has a Super Sensitive mode for extra gentle cleaning.

Overall, the iO 4 and 5 brush heads are the same, but the iO 5 offers one additional cleaning mode

Battery life and charging capabilities

The Oral-B iO Series 4 and 5 have similar battery life and charging capabilities. Both models use a rechargeable lithium-ion battery that provides an average of 14+ days of use between charges.

Both models come with a standard charging stand that takes around 16 hours to fully charge the battery. There is no significant difference in the charging speed or efficiency between the iO 4 and 5.

Smart features and app connectivity

The iO Series 4 and 5 both offer smart features and app connectivity, but the extent of these features differs between the two models:

In summary, both models offer basic app connectivity and real-time pressure feedback. However, the iO 5 provides more comprehensive real-time tracking and additional app features, such as brushing habit insights and personalized coaching.

How do the brushing experiences compare between iO Series 4 and 5?

The Oral-B iO Series 4 and 5 offer superior oral care compared to a manual brush. Both rechargeable electric toothbrush models feature the iO brush technology, providing a thorough clean with iO specific features.

The Oral-B iO Series 5 offers more advanced features, including 5 cleaning modes and the ability to use the app for personalized guidance.

Both models include a clean with iO LightRing timer to ensure proper brushing time and prevent users from brushing too hard. While the Series 4 and 5 are superior to Series 3 and iO Series 2, they may lack some features found in higher-end models like the iO 6 or iO Sense. However, both still maximize your clean with iO technology, offering a significant improvement versus a regular manual toothbrush.

Pressure sensor technology and feedback

The Oral-B iO Series 4 and 5 both feature a smart pressure sensor that provides real-time feedback on your brushing pressure. This helps you avoid brushing too hard, which can damage your gums and teeth.

Here’s how the pressure sensor works in both models:

Visual indicator: A light ring around the brush head changes color to indicate the pressure you’re applying:
White: Low pressure (not enough force)
Green: Optimal pressure
Red: High pressure (excessive force)
Motor adjustment: If you’re applying too much pressure, the motor will slow down to protect your teeth and gums.
App feedback (iO 5 only): The iO 5 connects to your smartphone app and provides additional real-time feedback on your brushing pressure, including a visual representation of the pressure you’re applying.

Overall, the pressure sensor technology is essentially the same in both the iO 4 and 5. The main difference is that the iO 5 provides more detailed feedback through the app, while the iO 4 relies solely on the visual indicator on the brush head.

Timer functions and brushing guidance

The Oral-B iO Series 4 and 5 both feature a timer and pacer to help you brush for the recommended two minutes and ensure even coverage of your teeth. However, there are some differences in how these features work:

Timer:

iO 4: The timer is built into the brush handle and provides audible alerts.
iO 5: The timer is also built into the brush handle, but you can also see it on the app for real-time feedback.

Pacer:

Both models use a pacer to help you brush evenly by providing a slight pause every 30 seconds.
iO 4: The pacer is activated by default and cannot be turned off.
iO 5: The pacer is deactivated when using the app in real-time tracking mode, as the app provides visual guidance for even brushing.

In summary, both the iO 4 and 5 have a timer and pacer to help you brush effectively. The iO 5 offers more flexibility with the pacer, as you can turn it off when using the app, but both models provide similar guidance for brushing time and coverage.

Gum care and sensitive mode options

The Oral-B iO Series 4 and 5 both offer sensitive brushing modes specifically designed for people with sensitive teeth and gums. These modes use a lower intensity setting to provide a gentler clean.

Both models also have a pressure sensor that helps prevent you from brushing too hard, which can irritate sensitive gums. Additionally, the round brush head and magnetic drive technology of the iO Series toothbrushes provide a gentle and effective clean.

Overall, both the iO 4 and 5 are good options for people with sensitive teeth and gums. The sensitive and super sensitive modes, combined with the pressure sensor and gentle brushing action, make these models suitable for those with sensitive oral health.
