You will not regret
on July 19, 2025
Posted by: olenay5_8827
[This review was collected as part of a promotion.] I’ve been using Oral-B iO brushes for a while now, and the Sensitive Gentle Care refills are hands down my favorite. I have sensitive gums, and these are the only heads that clean thoroughly without making my mouth feel like it went through a battle.
They’re super gentle but still effective. I get that deep-clean feeling, especially along the gumline, but without any soreness afterward. It’s like they found the perfect balance between soft and powerful. Even my dentist noticed less irritation and buildup at my last visit.
Swapping them on and off the handle is quick and easy, and I love how the bristles fade to remind me when it’s time to change them (a small thing, but actually so helpful).
I’ve tried a few different iO heads, but these are the ones I keep coming back to. If your mouth needs a little more TLC like mine does, you won’t regret giving these a try.

Good product

[This review was collected as part of a promotion.] Had a chance to try these brush heads from Oral B and they work really well. Love the circular brush heads and the bristles are soft for the gums but still do the job. I do wish the packaging was easier to store though.

Super clean 👌🏿 👏 🙌🏾

[This review was collected as part of a promotion.] I received this product from Influenster complimentary in exchange for my honest review 😀. I was so excited to receive my brush replacements because I used them before but couldn't afford to keep buying them. They brush really well and leave your teeth feeling super clean. My daughter has some loose teeth and it is sensitive enough so it won't hurt for her to brush. Our family ❤️ 😍 this .

Only iO compatible
on July 8, 2025
Posted by: roniekayy_6904
[This review was collected as part of a promotion.] I received these brush heads to try out, but unfortunately, I didn’t realize they were only compatible with the iO series — which doesn’t fit my current Oral-B toothbrush. Thankfully, my boyfriend uses the iO model, so I asked him to test them for me.
He was really impressed with how effective they were at getting that just-left-the-dentist clean feeling. The bristles are soft but sturdy, and he noticed his teeth felt smoother and looked brighter after just a couple of uses. He also appreciated how secure the brush head felt when attached — no wobbling like with some generic brands.
Overall, even though I couldn’t use them myself, based on his feedback, I’d definitely recommend these to anyone who owns an iO toothbrush. Just make sure to double-check compatibility before buying!

Right amount of softness!
on July 7, 2025
Posted by: crystalwhistle_4572
[This review was collected as part of a promotion.] My gums are super sensitive since I’ve gotten older so these sensitive brush heads are a must for me. They’ve been great to use since it’s the right amount of softness but still cleans. My gums aren’t irritated and my teeth feel great after using these brush heads with my Oral B toothbrush base. It was easy to attach and replace the heads as needed. The 4 pack is nice so I won’t have get a refill for awhile.

Oral B iO
on July 5, 2025
Posted by: brandibellnc_6216
[This review was collected as part of a promotion.] I honestly love these brush heads. I’ve got pretty sensitive gums, and these don’t feel rough at all—they’re super gentle but still leave my teeth feeling really clean. I noticed a difference in just a few days—less tenderness when I brush and my mouth just feels healthier overall. The bristles are soft but firm enough to do the job, and they fit perfectly on my iO handle. Bonus points for the fact that I got a deal on a 4-pack. Definitely worth it if you’ve got gum issues or just want something a little less harsh.

Perfect for Sensitive Teeth & Gums
on July 5, 2025
Posted by: danakebsch13_3364
[This review was collected as part of a promotion.] These Oral B iO Sensitive Gentle Care Refill heads work great with my Oral B iO Electric Toothbrush.. my Toothbrush when I bought it, came with the standard toothbrush head. This Gentle Care head works much better. It's more Gentle, the bristles are softer and it'works Great for Sensitive teeth. I wish my toothbrush would have came with each of the toothbrush heads when I bought it. I really like these Sensitive Gentle Care Refills much better, I will definitely get more of them. I highly recommend.
