Step up to more advanced hygiene with Oral-B’s iO Deep Clean Series 3 electric toothbrush while it’s back at $70 (Reg. $100)

$30 off/$70

Amazon is bringing the costs back down on the Oral-B iO Deep Clean Series 3 Limited Electric Toothbrush to $69.99 shipped. Mostly keeping up at its $100 MSRP for most of 2025, we’ve only seen one previous discount in the last four months that brought the price down to this same rate, with November and December having seen it go a bit lower to $60 before. We have seen it go even further to $40 in the past, but you’re otherwise looking at the second-best price at Amazon that we have tracked over the last year, giving you a solid $30 discount and stepping up your oral hygiene in the process.

This Series 3 Limited electric toothbrush from Oral-B is a great option to upgrade your oral hygiene over simple bristle brushes, especially with the three cleaning modes (daily clean, sensitive, and whitening) paired with pressure sensors to make sure your mouth is getting the proper attention it deserves.

Not only does it have a 2-minute timer built right in to make sure you’re spending the right amount of time brushing, but it even alerts you when the brush head needs changing. Along with the toothbrush, you’ll also be getting two starting brush heads and a travel case to take it with you whenever you journey far from home. Be sure to also check out Oral-B’s Amazon storefront here for deals on other brushes and replacement packs of brush heads, should you need to stock up.

If you want to take things a step further, you’ll also find the brand’s more advanced iO Deep Clean Series 5 Limited Electric Toothbrush down at $99.99 shipped from its $150 price tag. With this model, you’ll be able to track where your brush has scrubbed thanks to the AI-powered companion app. It has the same pressure sensors, brush head change alerts, two-minute timer – but bumps its cleaning modes to five options: daily clean, intense clean, sensitive, super-sensitive, and whitening. Along with the toothbrush, you’ll get a travel case and three brush heads to start you off.
