[This review was collected as part of a promotion.] I haven't noticed any whitening but I do like the feel of it. My dentist will be the final judge. The feeling of clean teeth and healthy gums should be the goal of your toothbrush. Buying this is a great start towards that goal, toothpaste and floss are the rest. Assuming you have a toothbrush to attach this to!

[This review was collected as part of a promotion.] These brush heads get my teeth super clean. Better than any other toothbrush I used. Very easy to pop on and start brushing when it needs changed. These are not irritating for my teeth or gums and very nice.

[This review was collected as part of a promotion.] Dental hygiene is a super important part of my daily life, so I was thankful to have recently received the Oral-B iO Ultimate Clean refills. The replacement heads come four to a pack, and although they are a bit more expensive, they are worth it. The Oral-B iO Ultimate Clean electric toothbrush head delivers a superior clean with its twisted and angled bristles, effectively removing plaque and leaving teeth feeling smooth and gums feeling healthy. Another great feature I love is that the bristles turn white from blue when they need to be changed. Overall, they are great quality, and durable, and my teeth are so much cleaner than other similar options I have used.

[This review was collected as part of a promotion.] I am not used to using a electric toothbrush so when I first used it it made my gums bleed a little bit. I have since learned to apply less pressure. It helped my teeth feel really clean but I still think I prefer a manual toothbrush.

[This review was collected as part of a promotion.] Never tried this spinner before and I really like it. Will be using it again. Hope the spinner works better than the manual toothbrush. I have teeth whitener that needs a lil spin on my teeth to work better. Thanks for this amazing opportunity to try before I buy more.

[This review was collected as part of a promotion.] Really nice brush heads ! Always love to replace my toothbrush heads and feel a fresh clean afterwards. This one in particular always provide a deep clean that is hard to get with a regular toothbrush, let alone a different electric toothbrush.

[This review was collected as part of a promotion.] These heads are fantastic. Because of all the motion I feel like I just got a good cleaning at the dentist. My dentist even told me I was brushing better. Helps very much with the areas that tend to get build up.

[This review was collected as part of a promotion.] I love my Oral B toothbrush. It works well, and the replacement heads last a long time. With the cost of manual toothbrushes anymore, I'm glad I only have to purchase the heads. They clean my teeth well and they spin to get them extra clean. I'll buy these until my toothbrush doesn't work anymore.

[This review was collected as part of a promotion.] I received these brush heads free in exchange for my honest review. I love the iOS toothbrush and these brush heads are all I have used so far. I love how clean my mouth feels after brushing. This is much more thorough than a manual toothbrush. While overall the toothbrush is pricey, you make up for it in the long run as you won’t be replacing a toothbrush but rather just the brush heads AND I would think you will get better dental reports based on how much cleaner it makes me feel. I love that these brush heads turn white with use so you know when to replace them. That feature is a money saver in my mind. Lastly I like that the brush itself is soft and paired with the features is this toothbrush, it is much easier to know you are brushing with the correct pressure and for the correct amount of time. My husband uses this too and we plan to upgrade our kids next.

[This review was collected as part of a promotion.] This is a good head replacement for my toothbrush. It snap right into place. Very easy installation and nice to get 2 heads in the package so I can always have a clean toothbrush head. The brush is round and small.
