[This review was submitted after receiving an incentive.] It’s like going to the dentist for a dental cleaning. My teeth really feel clean and smooth and I just love how easy the head to use, not too harsh and I just cannot wait to get more so my other half can try it too.

[This review was submitted after receiving an incentive.] Great easy-to-fix head for the iO toothbrush. Gives a great clean feeling and effective with whitening. Only issue I find is it's quite difficult to close my mouth around so can be a bit messy!!

[This review was submitted after receiving an incentive.] I have been using the Ultimate clean toothbrush head for over a week now and they really do deep clean your teeth. The round head makes it a lot easy to clean round the tooth. Highly recommend

[This review was submitted after receiving an incentive.] Dentist clean feeling without the visit. I cannot believe just how clean my mouth feels

[This review was submitted after receiving an incentive.] The brush heads are amazing and work so effectively at removing plaque off of my teeth which I felt that other toothbrush heads wouldn't. I would definitely recommend these to friends and family.

[This review was submitted after receiving an incentive.] I trust completely Oral-B brushes, as they have the best quality in the market! They really keep my teeth clean and also, they protect my gums to avoid any excessive pressure or damage on them

[This review was submitted after receiving an incentive.] I really enjoyed using these toothbrush heads. I like that they are round, it feels as though they are cleaning the entire tooth rather than just one side. I have noticed my teeth are whiter after a week of use. The heads feel sturdy and long lasting as well!

[This review was submitted after receiving an incentive.] I’ve been using the Ultimate clean toothbrush heads for 1 week now and they are excellent. The round head cleans the whole tooth rather than just the front surface. The head is really gentle on your teeth and gums whilst still doing a deep clean. I’d really recommend.

[This review was submitted after receiving an incentive.] These heads are simply fabulous. When combined with the genuine power of the iO, I could feel the clean working. The results were also visible instantly. Genuinely excited about continuing to use these heads alongside the iO brush.
