[This review was collected as part of a promotion.] Just restocked my Oral-B electric toothbrush heads and wow — nothing beats that fresh brush feeling What I love: ✅ Super easy to change out ✅ The bristles literally tell you when it’s time to swap (they fade from blue to white – so smart) ✅ Makes my toothbrush feel brand new again 💯 If you’ve been brushing with the same head for way too long, this is your sign to change it! Your teeth will thank you 😁✨

[This review was collected as part of a promotion.] I was really hoping these would be compatible with the sonicare toothbrush that I already own. Unfortunately, they were not. They do look like they are very sturdy and would last a long time. I love the smaller circular cleaning brush. It seems like it would make it really easy to get in between your teeth and be super effective.

[This review was collected as part of a promotion.] My teeth are the cleanest they’ve ever been! These IO replacements are a great value, easy to install and don’t require any scissors to open. The brush head is soft but cleans very deeply leaving my teeth feeling dentist cleaned after each brush!

[This review was collected as part of a promotion.] I received these oral b io brush heads in exchange for my honest review! I’m really excited to try these! My parents both have one, but I don’t have the base yet. I’m really grateful and can’t wait to see the results of switching from my regular oral b brush to this!! Thank you!!

[This review was collected as part of a promotion.] I love this product because it is easy to use and it helps rush my teeth better than with my regular toothbrush I love how it spins in order to get everything out and I love how you can get replacement heads so you don’t have to buy the toothbrush in it. It is a little pricey, but it’s worth the price. I receive this product in exchange for my honest review.

[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.] I’ve been using the Oral-B iO Series with the Ultimate Clean Refills for a few weeks now, and I can honestly say it’s made a noticeable difference in my daily dental hygiene. The combination of powerful yet gentle micro-vibrations and the round, dentist-inspired brush head gives a truly professional clean every time I brush. The bristles feel firm enough to effectively remove plaque but still gentle on my gums, which I appreciate. I especially love how the tufted bristles reach those tricky areas in the back of my mouth that I often struggled with using traditional brush heads. After each use, my teeth feel incredibly smooth and look visibly brighter. I also appreciate the recommendation to change the brush head every three months—it keeps me mindful of maintaining optimal performance and hygiene. Overall, these refills are well worth the investment if you’re looking to elevate your oral care routine. I highly recommend them for anyone who wants that fresh-from-the-dentist clean feeling at home.

[This review was collected as part of a promotion.] Durable, super clean, hygienic, easy to change and works great. I love this oral b and all oral b products. It is a great value, very easy to use and open. Packaged nicely. It is very comfortable on my sensitive gums.

[This review was collected as part of a promotion.] Absolutely loving my Oral-B iO Ultimate Clean Refills! They leave my teeth feeling super clean and polished—like I just left the dentist’s chair. The bristles reach every corner, and the pressure sensor is a game-changer for protecting my gums. Definitely a must-have for anyone using the iO series!

[This review was collected as part of a promotion.] My favorite toothbrush. I love these they give such a deep clean without being too aggressive. It really gets my gum line nicely and the small size makes it easy to reach around my wisdom teeth which is usually a hard spot to clean.
