Oral-B iO 9 vs. iO 8 vs. iO 7 Differences

Nowadays, electric toothbrushes are a must-have for any good dental cleaning. Their high efficiency in combination with the practicality for the user make them an enrichment in everyday life that you do not want to miss. As a leading manufacturer of electric toothbrushes, Oral-B is aware of its responsibility and the high quality requirements in this field. Accordingly, the company launched an innovative new series, the iO series, as early as last year to meet the increasing demands. The Oral-B iO 7, iO 8 and the iO 9 models have since become popular companions for dental hygiene. However, the differences between the models are difficult to see at first glance. In the following, we will show you the similarities and differences between the three toothbrushes.

The Oral-B iO 9, iO 8 and iO 7 offer cleaning programs for every need

All three toothbrushes have multiple cleaning modes that you can select to your liking.
The electric toothbrush [url="https://www.amazon.de/dp/B089MKVKG1?tag=monstec-21",name="Oral-B iO 7",title=""] has 5, the [url="https://www.amazon.de/dp/B089F6QXF2?tag=monstec-21",name="Oral-B iO 8",title=""] has 6 and the [url="https://www.amazon.de/dp/B094W93FB2?tag=monstec-21",name="Oral-B iO 9",title=""] has 7 different cleaning modes. All three models have the following modes in common:

1. Daily cleaning
   This is a standard programme that is suitable for daily use. With healthy teeth and gums, this programme is normally quite sufficient.
2. Sensitive
   This cleaning programme is particularly suitable for sensitive teeth. If you belong to the category of people who already feel pain in their teeth when biting off and chewing a slightly sour apple, you will certainly be pleased with this gentle programme.
3. Gum Protection
   Of course, there are not only sensitive teeth, but also sensitive gums. With this cleaning programme, you will see immediately if you apply too much pressure to the gums. In this case, the intelligent pressure control lights up red. When the pressure is optimal, the indicator lights up green instead.
4. Deep cleaning
   
   This programme should be used occasionally to clean the teeth, gums and interdental spaces particularly thoroughly.
5. Brightening
   This is not a cleaning programme in the true sense of the word, but rather an additional function. Tooth discolouration that makes your smile look less radiant can be removed with this programme. It is best to add this programme in the morning or evening after your normal tooth brushing routine.

In addition to these 5 programmes, the Oral-B iO 8 and 9 also offers you the 'super sensitive' mode. This mode could be interesting for you if you have exceptionally sensitive teeth.

The iO 9 electric toothbrush from Oral-B also offers a 7th mode, the extra tongue cleaning against bacteria formation. With the help of this programme, the tongue can be explicitly cleaned, whereby the toothbrush can be used in the entire oral cavity and additional cleaning objects become unnecessary.

On all three models, a warning light comes on if you press too hard - the so-called contact pressure control.

Battery life and charging time of the iO models

In terms of battery life and charging time, the three brushes are in no way inferior. The toothbrushes are fully charged after only 3 hours. If you brush your teeth twice a day for 2 minutes each time, the battery of the brushes will last for about 10 days. The Oral-B iO 9 also comes with a POWER2GO travel case, which has an integrated charging option - this can be especially handy when travelling if you don't want to/can't take the normal charger with you.

Display

While the display of the Oral-B iO 7 shows information in simple black and white, the display of the other two iO models is an oled colour display, i.e. coloured symbols inform you about the status of the toothbrush.

Cleaning Result

The cleaning results are very convincing with all three brushes. The Oral-B iO 8 and the Oral-B iO 9 score points here, of course, thanks to their additional programmes. In addition, the Oral-B iO 9 has an innovative tooth surface analysis that can detect all 16 tooth surfaces (zones), which is 10 more than the iO 7 and iO 8 models.

Colors

Not all versions are available in the same colours. If you place particular value on the visual appearance of your toothbrush, then the colour scheme could therefore be decisive for you. The Oral-B iO 7 electric toothbrush is only available in White Alabaster.

With the Oral-B iO 8, you can choose between the colours White Alabaster, Violet Ametrine and Black Onyx. The same applies to the Oral-B iO 9, where you can also choose between the three colours mentioned. The iO 9 also has chrome decorations on the underside and the neck of the handpiece.

Innovationen iO 7 vs. iO 8 vs. iO 9

All three models give you feedback on your cleaning behaviour via app. For this purpose, clear 3D graphics are available. As mentioned above, the Oral-B iO 7 and iO 8 divide into 6 different zones for which they provide feedback, the iO 9 even into 16 different zones. To synchronise the data, you can easily pair the toothbrush via Bluetooth. If you're wondering what the "iO" stands for - it stands for "intelligent oscillation": the toothbrushes recognise your brushing style, i.e. exactly which areas they have already cleaned and which ones they have not. Based on this, they give you feedback (in the app) on which areas they should clean more thoroughly to achieve an even result. You can also create routines in the app and receive "medals" for good cleaning. A nice gimmick. However, experience shows that apps in combination with toothbrushes quickly lose their appeal.

Pricing

Since the Oral-B iO 7 is the oldest and simplest model, this toothbrush is the best value for money. With a price of around 160 EUR, the Oral-B iO 7 wins first place, but is still no bargain for an electric toothbrush.

[asin="B089MKVKG1",type="standard"] With a price of around 180 EUR, the Oral-B iO 8 is just behind its predecessor, but still affordable. [asin="B089F6QXF2",type="standard"] The Oral-B iO 9 stands out a little more from the other two toothbrushes in terms of price. You should budget about 200 EUR for the purchase of this model.

Conclusion on the comparison of the iO 7 vs. iO 8 vs. iO 9

If you are looking for an electric toothbrush, you will be satisfied by reaching for an Oral-B toothbrush from the iO series. The Oral-B iO 7 is quite sufficient for daily use and is reasonably priced. However, if you are particularly keen on the colour of the brush, a coloured display or an additional programme, then the Oral-B iO 8 or iO 9 is the right choice. For those who travel a lot, the case of the iO 9 with charging function could be particularly helpful. No matter which electric toothbrush of the Oral-B iO series you choose - you will certainly get a thorough cleaning of your teeth with each of these models!
