Love My New Toothbrush!!!

[This review was collected as part of a promotion.] The Oral-B IO series is very nice and doing a good job. The toothbrush has a lot of features, bell and whistles too. This was my first experience with an Oral-B round toothbrush and I’m pleased. The instructing are easy to understand and there is also a phone app for the brush too. My toothbrush came with the device, brush head, charging cord and a carry case. My favorite thing about the brush is the lighted pressure sensor, red too hard and green is correct. The brush cleans like no other I’ve had, especially around my back teeth including my wisdom teeth. It has a two minute timer and beeps every 30 second to change brush position, I found out I wasn’t brushing long enough. The brush does feels bigger in my mouth but, I think it does a better job. The brush has different setting I change between different setting but I prefer the intense and mix with the whitening. My teeth feel like I just left the dentist office, clean. I’ve had no problems with the toothbrush, teeth or gums and it feels good taking care of my teeth and gums properly. I’ve already bought replacements heads and I’m enjoying brushing my teeth.

Battery saver

The user manual says this one can remain plugged up at all times. The battery burned out on my previous model because I kept it on the charger. There was no battery low indicator light on the previous model and I got tired of waking up to a dead toothbrush. This one says that the battery is protected from overcharging.

We love them!

Hesitant to purchase because of cost at first. I have used Sonic and Oral B for years. Sometimes in the morning and the other in the evening. Finally bought these because of the features and we do like them even more than the previous ones. The ability to “play games” so to speak on where you brush and what concentration you are seeking is kind of neat. It was a little pricey so hopefully it lasts. We’ve have the others for probably 5 or more years.

Strive to get the rainbow lights.

So far, I am enjoying the education I get from using the app showing me which teeth I have not been brushing the correct way and which teeth were not getting enough attention. I always thought I was doing a good job, but I was not. My teeth feel cleaner and slick when I follow the directions.

TREAT YO' SELF: Unleash the Power of Oral Care

Maintaining good dental health has always been a top priority for me however, as, I have gotten older and learned the correlation between mouth health and heart health, it has become an even higher priority. Over the years, I have tried numerous toothbrushes but none have impressed me as much as the Oral-B I/O series 5 rechargeable toothbrush dual pack. Let me share with you thy this toothbrush has become and essential part of my daily routine. First and foremost, the Oral-B I/O series 5 provides a superior cleaning experience that leaves my teeth feeling incredibly clean and fresh. The dual pack includes two toothbrushes, allowing me and my husband to enjoy the benefits together. The deep cleaning action of the tooth brush removes plaque effortlessly and ensure teeth receive a thorough cleaning, even in hard to reach places. One of the standard features that I absolutely love is the smart pressure sensor that alerts me when I'm applying too much pressure while brushing. This has been a game-changed for me, as I tend to a bit too enthusiastic with my brushing technique. Now, I can confidently maintain the right amount of pressure, protecting my gums from potential damage. Overall I'm really happy with this purchase. The change in how my teeth felt after brushing was immediate. I didn't even intend to make the purchase but I caught a great sale. We had an older model Oral B's (at least 6 years old). This upgrade was well worth the money.

Good toothbrush

Much quieter than my previous Oral-B, which is great. The shape makes it a little mor difficult with my clumsy hands to know what position it is in. The fact that it wants you to exert enough pressure to make the pressure light indicator to turn green, seems like a lot of unnecessary pressure. By the directions, you can't just brush, you must keep adequate pressure on the handle to trigger the green light. In all other aspects it is a great toothbrush.

Design flaw (mold and mildew issues)

I would seriously avoid this product. The Oral-B iO cleans my teeth really well, but there are two design flaws that drive me crazy. First, the charging base is shaped like a little bowl. Every time you put the toothbrush on it, water drips down and collects in the base instead of running off. After a while it gets gross, with slime and even mold if you don’t clean it constantly. A simple sloped design would have solved this. Second, where the brush head connects to the handle has a bunch of small crevices around the magnetic connection. Water and toothpaste get trapped there, and it eventually turns into black slimy buildup that’s difficult to clean. For something that spends its life in a wet bathroom, this seems like an obvious design problem. It’s a great toothbrush, but I expected better from a premium product. It shouldn’t require this much maintenance just to keep it clean. It should have been designed with an emphasis of proving mold and mildew development but instead it actually allows for it to grow. I looked into taking apart the base and trying to 3d print my own base but I’m just gonna find a D product that is not designed like this. I’m guessing most of which are to cut costs.

We are truly sorry you are not getting the experience you expected with the iO series 5 toothbrush. We want to assure you there is nothing in our toothbrush components that would cause mold, as mold requires organic materials. While rare, mold can develop after use if stored damp or with certain cleaning agents. We value your feedback for improvements, and if you need further help, please call us at (800) 566-7252.

This toothbrush has a design flaw in the head that allows spit and toothpaste to leak all down the brush and all over you. The back of the head has multiple holes to allow mold from building up in the head but it makes a big mess every time you brush your teeth. The toothbrush itself cleans the teeth well but not worth the mess in my opinion. I returned.

MOLD

Have only had this brush for a month, took it apart after a week to fully clean and there is mold growing in the head of the brush…. Sent a message to Oral B and all they can say is to take the brush apart every time and rinse with hot water and dry. I never had to take my old burst toothbrush apart for fear of mold. I wish I could return this because I certainly am not going to continue to brush with mold.

reply from Oral-B

We're very sorry to hear about your experience with your Oral-B iO Series 5. To help clarify, our toothbrush materials do not contain any organic substances that could produce mold on their own. However, in rare instances, mold can form after use if the brush is kept in a damp environment or exposed to certain soaps and cleaners that make the surface porous. We’d like to look into this for you, so please give us a call at (800) 566-7252.

We hate these! Even when you take them apart and rinse and dry them, they continue to leak toothpaste and mouth secretions down the handle and it settles in a gooey ring on the charger. The replacement heads are expensive and they wear down in a hurry. Our dental hygienist said hers does the same thing. I don't feel like my teeth are any cleaner with this brush than an inexpensive battery powered brush. Definitely not worth the money
