The Amazon Prime Day sale is now in its final day, and there are some impressive discounts on some of the best electric toothbrushes from Oral-B, Philips, Suri and more.
As the writer of IndyBest’s guide to the best electric toothbrush deals, I know how to spot a good discount from a dud. So, throughout the sale, I’m going to be tracking Prime Day deals in real-time to bring you only the genuine bargains.
My main advice for finding an electric toothbrush discount is to watch out for misleading offers. You’ll often see deep discounts of 50 per cent or more on the most popular brushes, but those seemingly huge savings repeat like clockwork throughout the year. To help make your life easier, I track the prices of electric toothbrushes year-round, so I can filter out the fake bargains and bring you only the best offers worth spending your money on.
Whether you’re ready to invest in a high-tech model with AI coaching and pressure sensors, or you want a reliable brush for that dentist-fresh feeling, I’ll be updating this page with new offers as they drop.

Why you can trust IndyBest to find the best electric toothbrush deals this Amazon Prime Day
The IndyBest team of shopping experts and I have been covering Amazon Prime Day for many years. I track the prices of electric toothbrushes year-round and know how to spot a good deal from a bad one. I’ve been researching the best electric toothbrush brands and testing a whole host of different options in my guide to the best, so I’m personally recommending the ones that I think are actually worth your money.
Best Amazon Prime Day electric toothbrush deals for 2025 are:
Oral-B iO2: Was £100, now £39.99, Amazon.co.uk
The Oral-B iO2 is the newest and most affordable electric toothbrush in the brand’s premium iO range, and right now it’s cheaper than ever at Amazon. The iO2 strips back all the bells and whistles of pricier models in the iO range “while keeping the all-important, premium, oscillating brush head technology”.
What’s most important is the cleaning prowess, and “here the iO2 excels by using the same oscillating technology as the rest of the Oral-B premium toothbrush range. Whisper it, but there isn’t a dentist in the world who could tell the difference between the iO2’s results and those of an Oral-B brush costing ten times as much,” I wrote in my review. There are also plenty of features to help with brushing, including a pressure sensor and a 30-second timer.
While it is currently £39.99 at Amazon, it does tend to hover around the £45 price point at other retailers, so the discount isn’t as huge as it might appear.
Oral-B iO6: Was £330, now £129.99, Amazon.co.uk
In my review, I found this hit “a sweet spot between price and performance”. And with 61 per cent off at Amazon, it’s now even better value.
It has a 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.
Oral-B vitality pro, two-pack: Was £80, now £36.76, Amazon.co.uk
This twin-pack gets you two Oral-B Vitality Pro electric toothbrushes for less than the usual price of one. A great no-frills option from a trusted brand, the Oral-B vitality pro two-pack is perfect for kitting out a couple or a family with an effective, dentist-inspired clean that won't break the bank.
Suri sustainable electric toothbrush: Was £75, now £56.25, Amazon.co.uk
Riding high in our best electric toothbrush round-up, the stylish Suri brush has a 25 per cent discount in the Prime Day sale. This eco-friendly brush ditches plastic for a slim aluminium body and recyclable, plant-based heads. Most importantly, it actually works.
In my Suri electric toothbrush review, I wrote that “Suri’s efforts to make the planet a bit less rubbish would be pointless if the electric toothbrush wasn’t up to scratch. Thankfully, it is.” I genuinely love this brush; I was impressed by its “practicality, sleek accessories, simple operation and great all-round cleaning power.”
Philips Sonicare 7100: Was £349.99, now £124.99, Amazon.co.uk
There’s currently a huge 65 per cent off the price of my favourite mid-range Sonicare brush: the 7100. When I put it to the test, it delivered dentist-fresh results. It features four brushing modes, a sensibly placed pressure warning light, and a premium look and feel.
Philips Sonicare 5300: Was £169.99, now £69.96, Amazon.co.uk
Philips Sonicare brushes use sonic technology to remove plaque, rather than an oscillating brush head, and the 5300 is one of the most affordable in the range. It features two brushing intensities and an ‘easy start’ mode that gradually increases intensity over your first two weeks of brushing to ease you into using an electric toothbrush.
Oral-B iO3: Was £160, now £69.99, Amazon.co.uk
Featuring in my review of the best electric toothbrushes, the Oral-B iO3 is one of the most affordable in Oral-B’s premium iO range. You get the same great cleaning performance and quiet oscillating motor as the most expensive brushes Oral-B makes, but with fewer brushing modes, a shorter battery life, no LED screen and no gimmicky smart features. It’s down to £70 in the Prime Day sale.
Oral-B pro 3: Was £100, now £42.49, Amazon.co.uk
If you don’t need all the fancy add-ons of pricier toothbrushes, the Oral-B pro 3 is one of my favourites. In my review, I praised it for its “refreshing simplicity” and cleaning power that left my teeth feeling “thoroughly scrubbed”. Right now, there’s more than half price at Amazon. It’s not an all-time low, but it’s still a decent saving compared to its price during the rest of the year.
Foreo issa 3: Was £89, now £59, Amazon.co.uk
When I reviewed the best electric toothbrushes, Foreo’s issa 3 came out on top for sensitive gums, thanks to the shape of the brush head and bristles, along with a choice of 16 intensity settings. I’ve never seen the model reduced at Amazon, and now you can save 34 per cent.
Philips sonicare cordless power flosser 3000: Was £119.99, now £63.64, Amazon.co.uk
I’ve spotted an almost 50 per cent discount on our best water flosser for Prime day. There are three intensity settings but even on the standard clean mode, it left our tester’s mouth “feeling fresh, visibly dislodging any food particles trapped between teeth”. It’s rare to see the price of this water flosser drop below £65, so now’s a great time to buy it.
Ordo sonic: Was £59.99, now £39.99, Amazon.co.uk
The Ordo sonic was my pick for the best electric toothbrush for whitening – “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.
Philips sonicare 3100: Was £89.99, now £42.53, Amazon.co.uk
Philips tops our expert-tested list of the best electric toothbrushes with its sterling sonicare 9900 prestige model, above. However, not all of us have £200 to splash on a new brush. The sonicare 3100 offers a more affordable alternative from this tried and trusted brand. It doesn’t have all the prestige’s premium features, but you still get a pressure sensor and Philips’ sonic tech which pulses fluid between the teeth for a deeper clean. If you want something in the middle, you can also pick up the mid-range sonicare 5300 – complete with a more powerful motor and two brushing intensity levels – for just £42.63 this Amazon Prime Day.
Oral-B iO5: Was £280, now £89.99, Amazon.co.uk
You’ll find plenty of features to improve your brushing on the iO5 including five different cleaning modes, a pressure sensor and app to tell you if you've covered your whole mouth. Right now, there’s almost 70 per cent off and this is about the lowest I’ve seen its price drop. While I haven’t tested this exact model, plenty of the iO series brushes have made it into my round-up, so it’s a range that you can trust.
Retainer cleaner tablets, 120: Was £15.99, now £10.25, Amazon.co.uk
A bathroom essential for anyone who’s had Invisalign, these retainer cleaning tablets are the cheapest we’ve seen at Amazon. The 36 per cent discount brings the price per tablet down to just 9p, so now’s your chance to restock the cabinet and treat those dentures to a sparkling finish.
Philips Sonicare 5500: Was £209.99, now £69.99, Amazon.co.uk
I’ve spotted another toothbrush from the Philips Sonicare range in the Prime Day sale. This one has a whitening mode that Philips claims can remove hard surface stains. I haven’t tested this exact model but plenty of brushes from the Sonicare range have made it into my top picks. There's now 67 per cent off, which isn't far off its cheapest ever price at Amazon.
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.
