Let’s take a look at the differences between the Oral-B iO series.

Cleaning modes

One of the main differences between the various models is the cleaning modes, which are 5 in the 7N Series, 6 in the 8N Series and 7 in the 9N Series. Specifically, the Oral B 7N Series has daily cleaning, sensitive, intense, super sensitive, whitening, gum care and tongue cleaning modes. The 8N Series has no tongue cleaning, the 7N Series has no super sensitive, no tongue cleaning.

Depending on your cleaning needs, one or the other model may be sufficient, but all of them can be used to clean the entire mouth adequately.

3D artificial intelligence

All models have artificial intelligence to recognise the position of the toothbrush in your mouth, but the 9N Series also provides a 3D representation to guide you based on the way you clean your teeth so you can reach every nook and cranny as effectively as possible.

Screen

All brushes have a full-colour, interactive OLED display. In addition, the 9N Series has 3D tracking with personalised coaching to make your brushing more effective.

Travel case

With the 7N and 8N Series, the travel case holds the brush handle and up to 2 brush heads, while the 9N Series holds only one brush head. To compensate for this, the 9N Series case allows for recharging while inside.

Price

Another big difference between the models is their price, although if you buy the Oral-B iO Series 7N, Series 8N and Series 9N on Amazon, you will see that sometimes there are offers where you can find superior models at a better price. In this case, considering how little they differ, it can be a determining factor.

Oral-B iO 7N Series vs 8N Series

The selling price of these two Oral-B Series is currently very similar, in fact you can find some offers on Amazon where the 8N Series is more recommendable. In addition, the 8N Series is available in 3 colours as opposed to the white of the 7N Series.

The 8N Series has 6 cleaning modes (daily cleaning, sensitive, super sensitive, intense, whitening and gum care) and the 7N Series only 5 (daily cleaning, sensitive, intense, whitening and gum care). The interactive display of the 8N Series is in full colour, just like the 7N Series.

The winning option is the Series 8 for price, screen and one more cleaning mode.

Oral-B iO 8N Series vs 9N Series

The 8N Series has a lower retail price than the 9N Series, although there are offers where prices can be very similar. Both have the same colour options, although they differ in one colour.

The iO 8N Series has 6 cleaning modes (daily cleaning, sensitive, super sensitive, intensive, whitening and gum care) and the 9 Series has 7 modes (daily cleaning, sensitive, intensive, whitening, gum care and tongue cleaning).

The 9N Series has full 3D tracking for increased cleaning performance, plus a power2go charging case for recharging inside. The 8N Series case is standard, has a larger capacity, but no built-in recharging.

The winning choice in this case is the iO 9N Series, unless you love the unique colour of the 8N Series. It has one more cleaning mode, 3D tracking and charging in its case. And if you find a good deal, the price variation is minimal.
