The Oral-B iO3 electric toothbrush has more than 65% off for Amazon Prime Day

It’s that time of year again: the Amazon Prime Day sale has begun, giving you the chance to bag big savings on your shopping wishlist. If you love a set of gleaming gnashers almost as much as a good bargain, we’ve spotted a whopping 65 per cent discount on one of our favourite Oral-B electric toothbrushes, as well as more top Oral-B deals.

The prices of electric toothbrushes tend to yo-yo throughout the year, so it’s well worth waiting for sale events such as Amazon Prime Day to pick up a new model for less. Oral-B is a tried-and-tested brand and, with a better-than-half-price deal available, the saving on the Oral-B iO3 electric toothbrush (£59.99, Amazon.co.uk) is one of the most compelling offers we’ve seen so far in the sale this year.

The iO3 sits in the middle of Oral-B’s iO range, offering the brand’s oscillating brush technology and a pressure sensor designed to alert you if you’re brushing too hard. It’s a straightforward option if you’re looking to switch from a manual brush or upgrade an older electric model, especially while it’s reduced.

It also took the top spot in our roundup of the best Oral-B electric toothbrushes, with it being described as marking a “turning point in Oral-B’s collection, where you’ll really start to notice the brand’s promise of a ‘professionally clean feeling’”. Keep reading for everything you need to know about the toothbrush, including how to snap up this deal while it lasts.

The Oral-B iO3 uses Oral-B’s iO technology to remove more plaque, while a built-in pressure sensor helps protect your gums from overbrushing. It also offers three cleaning modes and a rechargeable battery designed for everyday use.

In her Oral-B iO3 review, expert tester Lucy Smith wrote: “I enjoyed everything from the quadpacer vibrations that prompt you to move to the next section of your mouth to the pressure sensor light beneath the brush head, which gives a clear visual cue if you’re brushing too hard or too lightly.” Plus, she added that it’s two-week battery life meant it was “more than dependable” for daily use.

The toothbrush even comes approved by dentists with aesthetic dentist Dr Edoardo Felici explaining that this particular model “strikes a good balance between affordability and functionality. It includes pressure sensors and a timer, which are two of the most important features I look for”.

Right now for Prime Day, the iO3 is reduced from £175 to an incredible £59.99. So, what are you waiting for?
