Good

[This review was collected as part of a promotion.] I just unpacked the Oral-B iO Sensitive Gentle Care refill heads, and I’m really impressed! The packaging looks clean and premium, and the brush heads themselves feel very high-quality. They click onto the iO handle perfectly and look exactly like the original ones.
After trying them, I noticed how soft and gentle they are — perfect for sensitive gums, but still clean really well. I love that they don’t feel harsh or scratchy at all.
Definitely a great purchase, and I’ll be ordering these again!

Great Toothbrush

I love Oral B iO10. What happened to your replacement brushes in black for Sensitive Gentle Care Refills.
It sure would be great if you brought back your black replacement brushes for Sensitive Gentle Care Refill especially when you have an Oral B iO in black.

[This review was collected as part of a promotion.] These refill brushes are definitely worth it! They have soft bristles that are gentle on ur teach especially if you have sensitive teeth. They are more on the pricey side but they last a while and are very effective.

Gentle and effective.

[This review was collected as part of a promotion.] Alright I’ve been using these for a few weeks now and they’re great. Overall, if you have sensitive gums or simply want a gentler daily clean, this is it. It’s a small switch that makes brushing your teeth a little more enjoyable. You can tell the bristles are more flexible and softer but still the small compact round head so you can get behind teeth and crevices well. Still feeling super clean and getting a whole mouth fresh feel. Ooo and you get a better value with the pack so you’re good to go for while with 4!

[This review was collected as part of a promotion.] The brushes was nice and soft good for brushing teeth but I didn’t have the head so it was difficult to really test out but it will make a great buy if you have the head

The best manual toothbrush line!

[This review was collected as part of a promotion.] I love the oral b io line - I’ve been using the toothbrush for a couple years now. I typically use the regular brush head but this one is nice as well! The main difference is the bristles are smoother/more rounded shape which feels gentler.

Okay, Not Great for Teeth
on July 25, 2025
Posted by: brittanys481_7344
[This review was collected as part of a promotion.] These Oral B toothbrush heads are good but I'm not a huge fan of them. They were packed nicely and they were for sensitive teeth but I didn't feel like my teeth were clean enough after I was done.
