Best brush head I've Ever had! Why? Because it reaches really really well in between teeth and leaves your entire mouth feeling super fresh & clean. I've tried the Ultimate whitening replacement brush head and it's nothing special. It really can't compare to the Ultimate Clean brush heads.

[This review was collected as part of a promotion.] My husband loves these brushes. The set of brushes are individually placed so the ones you’re not using stay clean. They are comfortable and easy to use. They are very durable and effective for his teeth. He feels they are a great value.

[This review was collected as part of a promotion.] Oral B has always been tops when it comes to electronic brushing. These bristles on theses brushes are the best and very comfortable for the high speed the toothbrush goes. As a complimentary gift these are a great value for the money. The packaging always stands out.

[This review was collected as part of a promotion.] As expected, the brush quality really good. The brush head gives good quality feel when you actually hold it Brush are soft enough that won’t hurt your gums I understand they want to keep each brush separately for storing long term, hower the package feels like it’s too much plastic. They could wrap or pack each individual brush in more eco-friendly material rather than hard plastic and cardboard. It’s also difficult to open too :(

[This review was collected as part of a promotion.] I absolutely love my Oral B IO toothbrush! The brush heads are comfortable while brushing and have long durability. Packaging was easy to open and of course the brand is trusted and loved. Great value with the pack of 4. I have experienced great Oral care while using Oral B.

[This review was collected as part of a promotion.] I received this product in exchange for my honest review I've had this same brush heads with my iO 7 for approximately two years now and I've been satisfied with them. They clean all areas of the mouth including those tricky areas at the back efficiently. The brush heads are plastic and are relatively strong and last a reasonable amount of time, which makes the price worthwhile. The packaging is neat and easy to open which is a plus. One of the features I like is recognizing when to change the head, the color on the bristles fades to white means it is the time to change so there is no need for guesswork. I usually change the heads every four months, but they definitely do what I need. I will say they are a bit firm. It's ok for regular teeth but if you happen to have sensitive gums, they may be a bit rough. If you're looking for a good clean and don't mind a firmer feel, this is a great option. I recommend this product.

[This review was collected as part of a promotion.] I am obsessed with a round brush head. It makes such a difference. I am obsessed with teeth and my smile, and now they always feel dentist clean. Highly recommend spending the money and upgrading your daily toothbrush.

[This review was collected as part of a promotion.] The Oral-B iO Ultimate Clean brush head provides a superior cleaning experience with its advanced features. It features dual-length bristles that effectively clean both tooth surfaces and hard-to-reach interdental areas. It removes up to 100% more plaque along the gumline compared to a regular manual toothbrush. It has a smart pressure sensor which indicates when you're brushing too hard and helps in protecting the gums. In this pack there are four heads which are compatible with my Oral-B iO electric toothbrush.

[This review was collected as part of a promotion.] I’ve been using the Oral-B iO Ultimate Clean refills and they truly live up to the name! The clean feels professional—like you just walked out of the dentist’s office. What I love most is the balance: they’re super effective at removing plaque but still feel gentle on my gums. The packaging is sleek and hygienic, and each head lasts a good amount of time without wearing down. For anyone using the iO system, these refills are a must. They offer great value for the quality and comfort you get with every brush!
