Terrible Mold Issue — Not Worth the Money
The toothbrush develops mold. I tried keeping the brush separate from the base during the day so it could dry, but it still forms black pieces of mold that break off from inside the brush and you can’t clean them out of the base. Even after replacing it with a new brush, the same problem continued. Money wasted.

Thank you for sharing this with us, Marcela. Our Oral-B toothbrushes undergo rigorous quality and safety checks to ensure they are safe when used as directed. We're sorry to hear about this recent experience with your iO4. Oral-B iO toothbrushes feature openings in the brush heads to allow water to flush through the brush head tube and let air in, allowing the brush head to dry sufficiently after use and reducing moisture inside. There’s nothing in our toothbrush components that causes mold before use. Mold requires organic material to grow, which isn’t present in our brushes. While it’s rare, mold can develop after use if it's stored in a damp area or comes into contact with cleaning agents or soaps that can make the plastic porous. We recommend continuing to clean the brush head after each use. Your safety and satisfaction are important to us, and we'd like to learn more about your experience with your iO4 and help further. When you have a moment, please give us a call at 1-800-566-7252, 9 am-6 pm EST, Monday-Friday.

ABSOLUTELY!
[This review was collected as part of a promotion.] I love this thing! Not only are the bristles soft, not too harsh on my teeth but it really gets the job done. I don’t think I’ll even use a manual tooth brush again after trying this.

Great electric toothbrush
[This review was collected as part of a promotion.] I am amazed that it look me this long enough to try an electric toothbrush. It also connects to an app which can help with timing and certain challenges to complete. The battery life is great! Helps me complete that 2 minute washing teeth instead of rushing in the morning.

No longer works
I loved it, until it stopped working yesterday. I tried charging it on another toothbrush charger, to see if it was the charger, but it still wouldn’t charge.

We are delighted to hear that your Oral-B iO 4 Toothbrush has been an exceptional addition to your oral care routine, and we can understand the frustration with your brush no longer charging. All of our products are thoroughly tested to ensure their performance, so this is not something that we would expect to happen. We appreciate you trying a different charger, and would like to recommend also trying a different outlet, as well as ensuring that the brush is not sitting on a metal surface, as this can interfere with the electromagnetic charger. If these additional tips do not resolve the issue, we would love a chance to further assist you, and encourage you to give our team a call at (800) 566-7252 so we can get you back to your regular brushing routine and gather some information for our Quality Team.

Great
[This review was collected as part of a promotion.] Great design and very easy to use! I like the round brush vs the regular tooth brush shape. It doesn’t take long to charge and seems to last for awhile.

Love the rechargeable oral b toothbrush
[This review was collected as part of a promotion.] The oral b toothbrush came in nicely packaged. I really like that it is rechargeable so don't have to worry about replacing batteries. My mouth felt clean and refreshed with the electric toothbrush. The noise didn't bother me much. I would recommend this product as it does have a few modes to it where you know if you are brushing too hard or not enough. I recommend this product.

Very good tooth brush
[This review was collected as part of a promotion.] This is such a good toothbrush. It deep cleans a lot better than a regular toothbrush. There are different modes to it. It tells you when you’re pressing too hard of your teeth during cleaning and it’ll be green when it’s on the right pressure. The brush is pretty easy to replace. Battery life lasts a long time too.

Works Great
[This review was collected as part of a promotion.] My new tooth brush is awesome. Charged well, had great speed. The only thing I would like different is the head. I wish it was a bit bigger to reach more of my teeth at a time like a regular toothbrush.

My New Favorite Brush
[This review was collected as part of a promotion.] The pressure sensor is easily my favorite feature—I’m always told I brush too hard, and this helps me stay gentle without sacrificing a deep clean. I’ve been using electric toothbrushes for years and honestly didn’t think I’d switch, but this one totally won me over. The sleek design, the smaller brush head that gets into every corner, and the built-in timer to keep me on track? It’s all chef’s kiss. If you’re looking for a smarter, gentler way to brush, this is it.

Dentist clean at home!
[This review was collected as part of a promotion.] I love that this toothbrush times things out for you and has a little light party after you’ve brushed for the whole two minutes. My teeth feel cleaner and my gums aren’t in any pain from the brush head. HIGHLY recommend toothbrush!

Sleek and easy to use toothbrush
[This review was collected as part of a promotion.] This toothbrush takes all of the work and effort out of brushing my teeth! it's super easy to use and compact that makes it no problem to travel with. The only annoying part is having to charge it and there's a stand that takes up space on my bathroom counter

This is a great tool to use for teeth cleaning
[This review was collected as part of a promotion.] I was overall pleased with the noise level and cleaning performance. At first the initial contact was a slight bit rigorous but the more I used it, the more comfortable it became. The battery life is long lasting and its new design makes it easy to use. Definitely worth the price.

Never going back to regular toothbrushes!!!
[This review was collected as part of a promotion.] First used this toothbrush on a trip and I was amazed, I was using another electric toothbrush at that time and I took this one because of the traveling case because it was convenient, and I can say ever since that day I never gone back to the other one. Just amazing, it is in the pricier side but it is worth it. battery last long and it’s just amazing.

Cleen teeth
[This review was collected as part of a promotion.] I was very excited when I saw this campaign available because these products are of very good quality. I had never used electric toothbrushes before, so I decided to try them. At first, the vibration of the brush feels a little uncomfortable, but after one or two uses, you get used to it. I must say that my teeth feel and look quite clean compared to brushing with other traditional toothbrushes.

Smart toothbrush
[This review was collected as part of a promotion.] This oral-b rechargeable round brush head toothbrush with gentle micro-vibrations has 3 smart modes and can even detect if your brushing to hard. I noticed my teeth felt a lot cleaner than my usual toothbrush.
