[This review was collected as part of a promotion.] The Oral-B iO Ultimate Clean Replacement Brush Heads deep cleans between teeth and along the gumline. It’s super gentle bristles and only compatible with the iO line. It’s a bit pricey but of coarse you get quality with these brush heads.

[This review was collected as part of a promotion.] I’ve been using the Oral-B iO Replacement Brush Heads for a while now, and I’m really impressed with their effectiveness. They clean thoroughly and reach all the tricky spots, leaving my teeth feeling like I just came back from a dentist appointment. The durability is also excellent-each brush head lasts several weeks without losing shape or performance. In terms of comfort, they’re gentle on the gums but still provide a deep clean, which is perfect for someone with sensitive gums like me. They offer great value for money, especially considering the quality and performance. I also appreciate the packaging-it’s neat, hygienic, and easy to store the extra heads without them getting dusty. Highly recommend these for anyone using an Oral-B iO toothbrush!

[This review was collected as part of a promotion.] I absolutely love my Oral B IO toothbrush! The brush heads are comfortable while brushing and have long durability. Packaging was easy to open and of course the brand is trusted and loved. Great value with the pack of 4. I have experienced great Oral care while using Oral B.

[This review was collected as part of a promotion.] They fit perfectly with brushes and they have smooth placement. Product came as described, heads are just the right balance—not too soft or too hard on my gums, making them comfortable yet effective for a thorough clean

[This review was collected as part of a promotion.] These give a super deep clean and feel really gentle on the gums—no irritation at all. You can tell the difference right away compared to regular brush heads. They're a bit pricey, and only fit iO models, but honestly worth it if you want that fresh-from-the-dentist feeling every day.

[This review was collected as part of a promotion.] These brush heads get my teeth super clean. Better than any other toothbrush I used. Very easy to pop on and start brushing when it needs changed. These are not irritating for my teeth or gums and very nice.

[This review was collected as part of a promotion.] I really like these brush heads. I've used a lot of different electric toothbrushes but this is one of the best. Thee heads very easy to replace and left me with an extremely clean feeling. The bristles are soft but still do the job without hurting your gums.

[This review was collected as part of a promotion.] Everyone in my household uses the Oral-B iO system — myself and both of my children — so these Ultimate Clean refills don’t last long around here. The bristles are soft enough for sensitive gums but still leave our teeth feeling fresh, smooth, and genuinely clean after every use. I appreciate the color-fading bristles. With three people using them, it’s helpful to have a visual cue instead of guessing or keeping track of who’s due for a replacement. Price-wise, I think they’re fair for what you get. But how long they last really depends on your household. A 4-pack barely covers us. I usually go for the 6-pack — it keeps things simple and lasts a little longer. Bottom line? These refills are reliable, easy to swap, and they keep our brushes doing what they’re supposed to. If you’re already using the iO, just do yourself a favor and keep a box on hand.

In my youth, I went from dentist to dentist due to a congenital issue involving my jaw. I have tried every oral mouth tool created. I will continue to be devoted to Oral B; it truly is an impressive product. I have used competitors which were very good just not exemplary like Oral B. Thank you

Oral B has always been a top electric toothbrush innovator, and these heads are their flagship example. As an oral health professional I've used several generations of both Braun's Oral B and Philips' Sonicare, and they both have strengths and weaknesses. The latest iO series is Oral B's best in my opinion. It actually provides real feedback on where you've brushed, has multiple vibration strength settings, and is easy to clean and maintain. I've also used the latest Sonicare Prestige by Philips for comparison. The Philips is more compact, with a smaller brush head, and is quieter. The Oral B provides better cleaning in my opinion, and the semi-rotary action is superior to the sonic vibrations of the Philips for removing debris. The Philips works best on the maximum setting, which may actually cause sensitivity in some cases. The Oral B is equally effective at all settings, allowing the "Sensitive" settings (there are two) to be fully utilized. You are also provided more information on the toothbrush handle itself on the Oral B, with just a row of dots on the Philips. The software app is also better on the Oral B, although both are sometimes quirky with a Bluetooth connection. The Oral B software is slightly more stable in that regard, and since both brushes are "smart" AI brushes, the software becomes more important for value for your money - both brushes operate just fine with no software connection, but Oral B's app allows you to delete sessions (if you ran the brush by mistake for instance), pause the brush while using it (to rinse for example) , and run the brush head to clean it. The downside is that Oral B uses your phone's camera for "coaching," so to benefit from the app you need to be facing your phone and it occasionally loses its orientation. Still better than the accelerometer in the Philips, which frequently gets confused over whether you're brushing the front or back surface of your teeth, and has no option to record brushing the occlusal (top surface). You also are limited to 20 seconds brushing each sextant, and the app moves on whether you finished or not - the Oral B app doesn't switch sextants until your teeth are clean. All in all, a better brush and a better head than the latest Philips, for function and utility -again my opinion - but either brush will improve your brushing habits and oral health.
