[This review was collected as part of a promotion.] The Oral‑B iO Ultimate Clean replacement heads earn high praise for delivering a truly deep and thorough clean. Dental reviewers highlight its "Tuft‑in‑Tuft" bristle design and 16° angled bristles, which remove up to 100% more plaque along the gumline and reach tight areas between teeth. Great for the price and it's long lasting.

[This review was collected as part of a promotion.] The Oral B IO Ultimate Clean Refills makes brushing your teeth actually fun! The brush heads feel so good in my mouth, and it helps me feel like my teeth are getting a massage. They are very easy to put on/take off on the toothbrush. They last about 3 months, and are not that expensive to purchase.

[This review was collected as part of a promotion.] These toothbrush heads are the reason I purchased an iO in the first place. The soft bristles are varying lengths to help get between your teeth as you spend 2+ minutes exploring more than 3 mouth-cleaning settings on the toothbrush. These bristle heads come in recyclable packaging, and are a great deal in a multi-pack. I am a big fan.

It’s a little bit pricey but it’s worth it because it’s a very great quality and it will lasts for months instead of weeks. I definitely recommend this it’s worth the shot.

[This review was collected as part of a promotion.] These OralB iO Ultimate Clean Refills are the perfect replacement brush heads for my Oral-B iO Electric Toothbrush. I like that there are four refills in this pack. These brush heads have nice soft bristles to clean teeth gently and thoroughly. The bristles follow the shape of my teeth and gums effortlessly and feel gentle. I like that the color of the brush heads transforms from blue to white to signal that it is time to replace the brush head. With four replacement heads in one pack, I will always have a new replacement on hand!

[This review was collected as part of a promotion.] I received my Oral-b iO replacement toothbrush heads, unfortunately my Oral-b iO Series 7 toothbrush is only going to be available at the end of July. Unfortunately, these replacement heads are not backward compatible and only work with iO models. With that said, having used Oral-B electric toothbrushes for almost 10 years now, the new iO series really got me excited about the enhancements that Oral-b has developed. Having receding gums, I’m really looking forward to the iO’s ability to monitor my brushing and help me minimize my damage I do to my gums when brushing to hard. As always, I think this these replacement heads will be like the rest of Oral-b purchases, great products, great quality, great innovations.

[This review was collected as part of a promotion.] As a fellow daily user of the OralB iO Ultimate Clean refills, I can't imagine switching to anything else now! These brush heads have completely elevated my oral care routine from mundane to genuinely enjoyable. Each morning and night, I'm rewarded with that unmistakable dentist-clean feeling that simply wasn't possible before. The technology in these refills works perfectly with my iO handle, delivering those micro-vibrations that somehow manage to clean every hard-to-reach spot while being remarkably gentle on my sensitive gums. My teeth not only feel cleaner, but they actually look noticeably brighter since making these part of my daily routine. Yes, they're a bit of an investment compared to standard brush heads, but the difference in quality is immediately apparent—and my dentist has confirmed my oral health improvements weren't just in my imagination! For anyone who already appreciates these gems like we do, you know they're absolutely worth every penny for that unbeatable fresh-from-the-dentist feeling at home.
