Great Clean, BUT.....

Just purchased 2 this weekend, by dentist recommendation. Cleans wonderfully, BUT I have been using a Sonicare for years and was used to purchasing a smaller size brush head to reach the back teeth. That option does not exist with Oral B. Also no cap for the toothbrush head is available, nor does the series iO brush head stand up on its own due to the slant of the base. Not sure whether I will be keeping it.

Great brushes

[This review was collected as part of a promotion.] These brushes are great. Fit well and I dont have an issue with them popping off of the base. They do a good job cleaning and do not irritate my gums or feel like I'm using a wire brush to clean my teeth. Worth buying

It is amazing!

[This review was collected as part of a promotion.] Made my teeth feel freshly polished leaving them so smooth like I’ve just had a cleaning appointment! They no longer seem to not be as sensitive and no more bleeding which is great. Prices are not nearly as expensive as I thought it would be either. Highly recommended

Perfect

[This review was collected as part of a promotion.] My daughter got this toothbrush for Christmas so these came at a perfect time for her to change the head. She loves the feel of the heads - not too soft and not to firm - and they get her teeth really clean.

We Run Through These for a Reason!

[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.

Gentle cleaning.

[This review was collected as part of a promotion.] I have used an oral b electric toothbrush for years. I love the smaller round brush head. I have a small jaw, so anything larger will not fit into the back of my mouth. My dentist recommended oral b and I am so glad he did. I have excellent cleanings, very little plaque. The oral b brush heads are small enough to get behind my back teeth, without a lot of discomfort. The brush head spins around to ensure that you get every inch of each tooth. The brush head cleans the gums as well, without a lot of unnecessary pressure. I am very pleased with the results from the oral b io brush heads.

great results

[This review was collected as part of a promotion.] i have used an electric toothbrush for as long as I can remember. For some reason, I had never tried a round replacement head before. I'm so glad I did. I felt like these did a better job of massaging my gum line, a well as getting small particles of debris out.m

Amazing

I have a smart toothbrush by them and these refills are so expensive so I was so happy to receive them. I have to change them always and these heads are very great so I highly recommend them
