Amazon Prime Day 2025 is almost here, and this year's event promises to deliver a huge range of electric toothbrush deals. Kicking off tomorrow (Tuesday, 8 July) and running until Friday (11 July), Prime Day is renowned for offering significant discounts across tech, beauty, home and more, and electric toothbrushes are no exception.
Some top models from Oral-B and Philips Sonicare are already discounted. Whether you're after smart features like AI brushing feedback, pressure sensors, or simply a reliable brush that leaves your teeth feeling professionally cleaned, there's likely to be a deal that suits your needs and budget.
However, we’ve noticed that prices for popular electric toothbrushes can fluctuate ahead of big sales events like Prime Day, so not all of these deals are legitimate. That’s why we’ve rounded up some of the best electric toothbrush deals you can shop right now – and they’ve all been tried and tested by our experts.
Amazon has confirmed that Prime Day 2025 will return for four days from Tuesday, 8 July to Friday, 11 July. Expect big savings on high-tech items, including electric toothbrushes such as the Oral-B iO6 and Philips Sonicare 7100, which were heavily discounted in previous sales.
- Philips Sonicare 7100: Was £349.99, now £124.99, Amazon.co.uk
- Philips Sonicare DiamondClean smart: Was £399.99, now £203.09, Amazon.co.uk
- Oral-B iO9: Was £500, now £219, Amazon.co.uk
- Oral-B iO6: Was £330, now £199.49, Amazon.co.uk
Philips sonicare 7100: Was £349.99, now £124.99, Amazon.co.uk
Our tech critic Steve praised the Philips Sonicare 7100, in his review of the best electric toothbrushes, as a solid mid-range option that offers “seriously powerful” sonic cleaning at a much more affordable price point, made even better with an additional 64 per cent off from Amazon.
While it lacks some of the high-end features of the 9900 Prestige model, it uses the same 62,000 vibrations-per-minute technology, delivering “genuinely dentist-fresh results.” Steve also preferred the Sonicare’s “small oval brush head and thin neck,” which made reaching back teeth easier than other bulkier brushes.
Philips sonicare diamondclean smart: Was £399.99, now £203.09, Amazon.co.uk
In his review, Steve found the diamondclean smart to be a premium electric toothbrush that combines sleek design with smart features. The standout detail is its “special charging glass,” which doubles as both a wireless charger and a regular rinsing cup: “a genuinely clever solution” for those mindful of bathroom aesthetics, even if not hugely practical.
The toothbrush itself is praised for its elegant look and long-lasting battery (lasting a week between charges). Plus, now you can grab one of your own with an almost 50 per cent discount.
Philips Sonicare 9900 prestige: Was £549.99, now £259.99, Amazon.co.uk
Here's a huge saving on a premium brush from the Philips Sonicare range. The manual switch on the toothbrush takes you through three brushing modes, which you can then customise in the Philips Sonicare app. This will send you real-time feedback and brushing mode recommendations, which actually helped Steve improve his brushing form, he noted in his review.
As we often see with electric toothbrushes, its price tends to fluctuate on Amazon. If you notice it creeping back up, it’s worth holding off until it drops again.
Oral-B iO9: Was £500, now £219, Amazon.co.uk
The Oral-B iO9 electric toothbrush was picked in our review as the best for orthodontics, and praised as a premium option that “packs a punch” with its smart design and powerful clean. Sitting just below the flagship iO10, the iO9 still offers “a similar suite of premium features,” according to our tester, including seven cleaning modes shown via intuitive LED graphics. It’s rare that you’ll need to pay full price for the iO9, as it’s often reduced at Amazon.
Its oscillating action is noted to be “more effective than a sonic brush for cleaning around orthodontics,” making it ideal for those with implants or braces.
Oral-B iO6: Was £330, now £199.49, Amazon.co.uk
The Oral-B iO6 electric toothbrush is described by Steve in his review as hitting “a sweet spot between price and performance”. And with 40 per cent off at Amazon, it’s now even better value.
Steve highlights its great digital display, the cheapest in the range to include one, making it “easier to see at a glance which of the five brushing modes you’re currently using, as well as things such as battery life and when it’s time to replace the brush head.” While it doesn’t include all the bells and whistles of the iO9, such as the magnetic charger and travel case, the essentials are all here, making the iO6 “a marginally more budget-friendly” but capable choice.
Ordo sonic: Was £59.99, now £45.98, Amazon.co.uk
The Ordo sonic is our pick for the best electric toothbrush for whitening. In his guide, tech expert Steve Hogarty says that “all our testers felt that this addition was very effective in getting rid of longer-term stains.” It might not be as fancy as some of the big hitters, but this simple brush is perfect for those on a budget.
Oral-B pro 3: Was £100, now £47, Amazon.co.uk
If you don’t want to spend hundreds on an electric toothbrush, this no-frills model from Oral-B is a trusty option that “delivers a reliable, thorough clean”, according to our tech critic, Steve. He found that his teeth “felt fresh and thoroughly scrubbed” after using it – he couldn’t ask for much more, which is why it earned a spot in our round-up of the best toothbrushes. It often drops in price on Amazon, and right now, there’s almost 50 per cent off. We’ll let you know if there are more reductions when Prime Day starts tomorrow.
What is Amazon Prime Day?
Prime Day is Amazon’s exclusive mega sale for its Prime members. It typically runs for 48 hours, but this year you’ll have four days to shop the sale. It usually happens twice a year – once in the summer and again in the autumn. During the event, shoppers can find huge discounts on major brands, including top-rated, tried and tested electric toothbrushes.
Do you need to be a Prime member to shop for electric toothbrush deals?
Yes – access to Prime Day discounts is limited to Amazon Prime members. A membership costs £8.99 per month or £95 annually, though students and young adults (ages 18–22) can claim a 50 per cent discount and a six-month free trial. Perks go beyond the sale and include speedy delivery, Prime Video, and access to exclusive deals.
If you’re not already a member, you can still take part by signing up for a 30-day free trial. This gives you full access to Prime Day offers – including any price drops on premium toothbrushes – with the option to cancel before being charged. Just note: the free trial only works if you haven’t used it before.
