Amazon Prime Day is a great opportunity to snag yourself a new electric toothbrush. These high-powered devices can clean away more plaque than a manual toothbrush can, but when browsing the best electric toothbrushes online, it can be difficult to tell which of the Prime Day deals are really any good.

There's just so much jargon around toothbrushes, complicating a seemingly very simple action, which can make it difficult to identify the really good deals. 

Fortunately, we've written enough about electric toothbrushes to really know our stuff, and we're on hand with some of the deals below we think are really worth your time.

Philips Sonicare Diamondclean 9500 | $269.99 now $159.99 at Amazon
Save $110 -
With a head resembling a traditional toothbrush rather than an oscillating circle, the Diamondclean 9500 is a great brush with its own smart ecosystem and five modes. The glass in the picture is actually a charging station, which is a really neat trick. 

There's so much to unpack here. Plenty of these discounts are big, because they're on high-priced items like the smart connected toothbrushes with AI and companion apps. These apps can tell you if you've brushed the different zones of your mouth for an appropriate amount of time and can jolt your memory if you forget to brush at your usual time. 

Although this is a useful feature for developing good hygiene, you can eschew this for a really good deal on a brush. The best deal on the list above, the Oral-B Pro 5000, doesn't come with in-built AI, but at $100 or 63% off, it's by far the biggest proportional discount on the list. 

Other items include brushes for kids, and accessories such as rechargeable Power Flossers. For more advice on choosing the right brush for you, check out our guide on how to get the best electric toothbrush deals for you on Amazon Prime Day
