We switched from Philips to Oral-b because of the small brush heads - they say smaller brush heads can reach more tight corners and clean better but these small brush heads are thick! Thick plastic head and then the brush it self.... :( still can't

[This review was collected as part of a promotion.] GREAT brush heads. The oral b iO line is one of the best brushes in the market. Does an amazing job of keeping all areas clean and is super gentle! Also easy to switch out and transport.

[This review was collected as part of a promotion.] Great replacement heads for my toothbrush! They work great and are comfortable while being effective at cleaning. They’re a good value for the money while being durable and packaged nicely.

[This review was collected as part of a promotion.] These brush heads work really well. I went and purchased the toothbrush and I feel like my teeth are really clean. It’s comfortable to hold and very durable.

Really does a great job of cleaning teeth, while being gentle on gums. Question: What is the function of that narrow little slot which is just under the bristles?

[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.

[This review was collected as part of a promotion.] These replacement brush heads are great. They come in 4 individual packs and are easy to open and replace. The brush heads are soft but feel so good brushing.
