Excellent cleaning feel, but the smart extras are not essential
Walmart shoppers rate the Oral-B iO Series 5 4.5 out of 5 across 858 ratings, and two independent reviewers say the brushing experience is hard to fault. Both also note that iO-specific brush heads cost more than standard Oral-B heads and that the app coaching is not essential. Battery life is decent rather than great. It is a good fit if you want the pressure ring and round-head feel; if you mainly want clean teeth for less, a simpler Oral-B or a Sonicare may serve you as well.

This review summarizes user experiences and expert reviews and is not dental or medical advice. If you have gum disease, sensitive teeth, braces or other dental concerns, ask your dentist which brush and mode suit you.
The Oral-B iO Series 5 is a rechargeable electric toothbrush with a round oscillating-rotating head, five brushing modes, a light ring that works as a pressure sensor, and Bluetooth app coaching. It comes with one Ultimate Clean head, a charger and a travel case, according to the Walmart listing.
Because it sits in the premium tier, we looked at whether the extras justify the step up from simpler brushes, using a retailer rating and two expert reviews.

What users complain about
How it holds up over time
We found no long-term durability testing. Reviewers doubt many people will keep using the real-time coaching long term, which suggests the lasting value is in the brush itself and the pressure ring rather than the app. A simpler iO model cleans just as well, according to Electric Teeth.
Tips from users
- Watch for head deals and stock up, since iO heads are required.
- Rinse the head and handle junction after use and clean it regularly.
- Brush a little longer than two minutes if the app shows missed zones.
- Use Sensitive mode if your gums feel tender, and check with your dentist.

Frequently asked questions
Do I need the app?
Not to brush. But on the iO5 the app is used for setup and most settings, and for the real-time coaching.
Are iO brush heads interchangeable with older Oral-B heads?
No. The iO range needs iO-specific heads, which reviewers say cost more than standard Oral-B heads.
How long does the battery last?
One reviewer averaged about 17 days per charge. Another cites a maximum of about two weeks.
Is it worth it over a basic Oral-B?
If you value the pressure ring and quieter, softer feel, many reviewers say yes. If you only want clean teeth for less, a simpler brush may do.
