Best budget: <\/strong> Oral-B iO Series 3 (iO3) \/ Walmart<\/a>, Amazon<\/a> \/ ~$107.31<\/p>

Our verdict<\/h2>\n\n\n\n

All of the iO Series brushes have a 2 minute timer, pacer and pressure sensor. These are the key features that dentists recommend.<\/p>\n\n\n\n

All models clean your teeth as well as each other.<\/p>\n\n\n\n

What sets them apart are additional features. Examples include more brushing modes, in-handle display and \u2018smart\u2019 (Bluetooth) technology. These are nice-to-have, but not critical.<\/p>\n\n\n\n

The iO6 is the best value option. It strikes the balance between additional features and price. It has some smart features, but not the full suite. <\/p>\n\n\n\n

Technically, the iO2 is the most affordable, but we recommend the iO3 as we think it is a better buy because of the pressure sensor setup compared to the iO2. The iO3 does not have smart features.<\/p>\n\n\n\n

The iO9 is for those who want all the tech and are prepared to pay for it. It offers far more than you need.<\/p>\n\n\n

Which cleans the best? <\/h2>\n\n\n\n

A reasonable question, given the range in price. <\/p>\n\n\n\n

But, simply put, they all clean as well as each other.<\/p>\n\n\n\n

All models within the iO range (except the iO2) use the same brush motor with the same configuration.<\/p>\n\n\n\n

Models like the 8 and 9 Series do have extra cleaning modes compared to the 3, 4 and 5. But, these modes don\u2019t change the actual cleaning results.<\/p>\n\n\n\n

Using the intense mode won\u2019t necessarily remove more plaque from the teeth and gumline. You don\u2019t need a whitening mode to make your teeth whiter \u2014 the daily clean mode can achieve this.<\/p>\n\n\n\n

Your brushing time and technique have a far bigger impact on the cleaning results than the mode you use.<\/p>\n\n\n\n

What sets the brushes apart is the other features they come with. We compare these throughout the article. <\/p>\n\n\n\n
