Today's best electric toothbrush deals (US)
Oral-B iO Series 9: was $299.99 now $237.49 at Amazon
Amazon is yet to slash the price of our top-rated Oral-B iO Series 10 toothbrush, so you'll have to pay almost $400 for the pleasure of owning one. However, you can snap up the slightly older series nine for just $237.49 courtesy of an early Prime Day discount.
Oral-B iO Series 6: was $169.99 now $148.99 at Amazon
The Oral-B iO Series 6 is our best mid-range electric toothbrush. It offers a near-silent motor, real-time feedback and a smart pressure sensor for less than half the price of our top-rated toothbrush, the Oral-B iO Series 10.
Oral B Genius X: was $199.99 now $99.99 at Amazon
Save 50% on this AI-powered toothbrush with six teeth-cleaning settings, a travel case, and a handle that connects to the Oral B app for real-time AI guidance. It was a hefty $200, but now it's down to under $100.
Suri Sustainable Sonic Toothbrush: was $116 now $87 at Amazon
This is an excellent toothbrush for anyone chasing a quality product with a sleek design and some bonus sustainability credentials (it uses recyclable plant-based materials for the replaceable heads and bristles). Now it's cheaper than ever on Amazon, thanks to a 25% Prime Day discount.
Waterpik Aquarius water flosser: was $99.99 now $49.99 at Amazon

Today's best electric toothbrush deals (UK)
Suri Sustainable Sonic Toothbrush: was £62.50 now £56.25 at Amazon
There are savings to be made in both the US and UK on this sterling Suri toothbrush over Prime Day, with both benefiting from a quarter off. That means you get fast-charging, more than 40 days of juice per charge, two modes (everyday clean and polish) and a powerful clean for less than £60.
Oral B Genius X: was £109.99 now £89.99 at Amazon
The RRP on the Oral B Genius X is actually a lot lower in the UK than it is in the US, but a decent 18% discount means you'll still find it at around the same price point. £90 is a good price for this toothbrush if you think you'll be using the AI guidance regularly.
Oral-B Vitality Pro: was £49.99 now £23.46 at Amazon
This budget-friendly electric toothbrush is currently less than half price on Amazon, and while it offers a solid clean it misses out on some features that come with better models (such as a pressure sensor and reminders when you need to change your head).
Oral-B iO Series 6: was £299.99 now £131.8 at Amazon
In our four-and-a-half-star Oral-B iO Series 6 review we commended the toothbrush for having a really quiet motor, while still offering a great clean boosted by help from the app. It won't just time how long you take and warn you when you're pressing too hard, it'll show you where in your mouth needs more or less attention so that you can remember to keep your whole mouth clean.
Philips Sonicare 7900 was £249.99 now £89.99 at Amazon
This electric toothbrush is a little pricey for what you're getting features-wise, but it boasts several cleaning modes and a handy app that promises to help you improve your dental hygiene habits. Save a massive 64% right now.
Philips Sonicare ProtectiveClean 4300 was £139.99 now £59.99 at Amazon
This midrange toothbrush offers a solid clean and comes with a case to carry your toothbrush in when you travel, however, it lacks the bells and whistles of other models. Still, for this price, it's a fabulous sonic model with included charge stand and carry case.
Amazon Prime Day electric toothbrush deals: FAQs
Do I need to get Amazon Prime to get the best electric toothbrush deals?
Yes, to put it bluntly. Amazon loves to run sales events exclusive to Prime members in order to entice people to sign up to its premium service, so some discounts will be hidden from, or inaccessible to, non-Prime members.
Fortunately, it's great value if you're a regular Amazon user, but you can cancel after the event is over if you don't want to pay that $14.99 / £8.99 / AU$9.99 subscription service price. More on that in a minute.
Which electric toothbrush should I buy on Amazon Prime Day?
That's a tough one, and it will all depend on your budget and needs. If you're prepared to spend hundreds of pounds or dollars, you're likely to get a much bigger discount (for example, in the US, you might get a $400 toothbrush marked down to $250) than you would on a cheaper toothbrush, so the more you spend, the more you'll save. An Oral-B iO Series brush, is probably your best best.
However, when it comes to cheaper toothbrushes, you might be able to get brushes like the Colgate Hum or Ordo Sonic+ for half price or more. Don't forget about replacement heads either, as bundle deals will crop up: shop right, and you could get a year's worth of brushing on the cheap.
How to get access to the Amazon Prime Day electric toothbrush deals for free
When you sign up to Amazon Prime, you get your first 30 days with the service free. When you're finished shopping the deals, you can simply cancel your Prime subscription before the 30-day mark and you'll never have to pay a thing for the service.
