[This review was submitted after receiving an incentive.] I recently purchased ultimate clean as I needed a new brush head . I was excited to try this range. No doubt it leaves clean feeling, bristles are bit hard and stiff , the round tiny shapes make it easier to reach hard area. I haven't noticed my teeth any whiter than usual . I brush twice a day. Having said said that I will definitely repurchase if

[This review was submitted after receiving an incentive.] I have been using io10 for years and I keep using ultimate clean brush heads. This is my first time trying radiant white brush heads and it really surprised me. I have been using Oral-B 3D white advanced luxe perfection toothpaste for some days, but the improvement is not obvious. After trying the radiant white brush heads together with the toothpaste, the whitening effect is much more obvious. I can tell the improvement after few days! Will keep using this combination and look forward to the whitening effects!

[This review was submitted after receiving an incentive.] I initially liked the brushes, and thought the polishing petals sounded cute. I took before and after photos each day, and after two weeks I could see a very very slight difference. Certainly not within a day like it claims. Also a part of me felt that because they were focused on whitening, i felt i spent more time cleaning the front of my teeth that you can see and probably neglected the back more than I did when using the normal heads. I have noticed my gums being more sore since using them so I don't know if they're just too much for me. I would of scored higher if the package hadn't been so focused on whitening.

[This review was submitted after receiving an incentive.] So these are great at cleaning teeth, leaving you with a clean mouth and smooth teeth when you run your tongue over them. Have they whitened my teeth? It's negligible to be honest, they clean off new stains but my teeth are old and stained and without serious chemical treatment these along with my toothpaste are the best they are going to get and they aren't getting any worse with is great.

[This review was submitted after receiving an incentive.] These whitening toothbrush heads which I was given to test out ars simply fantastic. I have been using an Oral B IO toothbrush and heads for some time now. So I have a good knowledge of them. The whitening heads are very good at removing daily stains from your teeth i.e Coffee,tea and even if you are a smoker. I would have to say that they are certainly the best toothbrush head to clean your tongue with too. Moving off the heads shortly... I think that Oral B should install the cleaning of the tongue facility on all of their toothbrushes, as that's where most of the germs are (over 80%). I will definitely carry on using these whitening heads. They do exactly what 'is said on the package'…

[This review was submitted after receiving an incentive.] I've been trialling the Oral-B iO Radiant White toothbrush heads (gifted via SavvyCircle), and they've earned a firm spot in my routine. They click onto my iO handle securely, feel gentle on gums, and the bristle pattern really hugs each tooth. After a week, I noticed that just-back-from-the-dentist smoothness especially along the gumline and between teeth where plaque loves to linger. Tea and cola are my weaknesses, and while no brush head is a magic wand, these genuinely helped lift that day-to-day staining so my enamel looks brighter and feels cleaner. The polishing cup in the centre seems to guide paste where it's needed, and the tapered outer bristles sweep the gumline without that scratchy, inflamed feeling I've had with cheaper heads. They also don't splay quickly after two weeks the bristles still look neat, so I'm hopeful they'll comfortably last the usual three months. I used them across Daily Clean and Whitening modes; both felt effective without being harsh, and there's no buzzing irritation on sensitive days. A few practical wins: they rinse clean easily (no gunky build-up at the base), the replacement colour rings are handy if you share a handle, and the head size is small enough to manoeuvre behind molars. The only watch-outs are price (they're premium) and making sure you match the head to an iO handle these won't fit older Oral-B models. Standouts I loved Noticeably smoother teeth and a gradual lift in surface stains Gentle on gums with precise gumline cleaning Sturdy bristles that keep their shape Could be better Premium price point iO-only compatibility

[This review was submitted after receiving an incentive.] Enjoyed using this product, gave good results and teeth appeared whiter and less stained. Was pleased to have tried these toothbrush heads.

[This review was submitted after receiving an incentive.] I have been using io brushes for around 2 years and I do agree these feel like they give an overall better clean. I didnt notice a huge difference to the shade of my teeth though. Still would buy them going forward and I do recommend as they definitely make your whole mouth feel cleaner.

[This review was submitted after receiving an incentive.] Great brush heads, really make your teeth feel extra clean like a firm manual toothbrush. A definitite improvement on the ultra clean heads.
