Our favorite smart electric toothbrush is $70 off right now
The Oral-B iO Series 7 smart electric toothbrush is down to $149 at Amazon after a $71 discount. That matches the best price we've seen and returns it to the low it hit for the shopping holidays last year. The deal comes as part of a larger sale in which Oral-B toothbrushes are up to 55 percent off. We named the iO Series 7 the top pick in our guide to smart toothbrushes because it hits a good balance between features and affordability (particularly if you can catch it on sale like right now).
We tested a handful of smart electric toothbrushes (in this case "smart" means app-connected) and ultimately liked this one best. It has a black and white LED screen that tells you helpful info like mode, battery life and how long is left on your two minute timer. The vibrating head is vigorous but not lip-numbing like other models we tried and the lighted ring helpfully indicates whether you're pushing too hard or not quite firmly enough.
If you want to brush while looking at your phone, you can watch an animated recreation of a set of teeth that slowly turns from blue to white as the internal sensors track the position and movement of your brush. It's a bit of a surreal experience, but I did notice my teeth felt cleaner after using this than they do with a standard brush.
This set comes with a replacement head, travel case and charging dock which you should only need to use a couple times per month. If you want something even fancier, the Oral-B iO Series 9 is also on sale. The Series numbering refers to the level of features, not the newness of the brush, so Series 9 has extra brush modes, a color LED screen and a charging travel case — all of which the Series 7 lacks. Though in my tests, I didn't find those perks were worth an additional $100.
