There are far too many electric toothbrushes on Amazon to choose from

Electric toothbrushes are popular buys every year in the Amazon Prime Day deals, so much so that the website is absolutely flooded with the things. Not only do you have vast amounts of models from the old guard of Oral-B, Philips, Colgate, and more, but you have newer upstarts like Suri, Ordo, and Supermouth to browse, as well as Amazon's usual slew of no-name dupes.

All the while, they're all packing different features, be they pressure sensors, multiple modes, AI brushing guidance, or reward points. It's getting harder to choose between them due to all the noise!

That's where I come in. I've reviewed plenty of electric toothbrushes in my time as TechRadar's resident health tech editor. I've curated our best electric toothbrushes buying guide, and I've picked out a trio of products that are a) all discounted during Prime Day, and I believe are going to be good value for money. For comparative purposes, I've grouped them into three categories: under $50, under $100, and under $200. Let's get started!

Under $50: Ordo Sonic Lite

I liked this electric toothbrush when I reviewed it in 2024, calling it 'simple and feature-light, but terrific value'. Therefore, even though it's a tiny discount (the Ordo Sonic Lite was $38.47, but is now $34.99 at Amazon), the brush is such a good value normally that I still feel comfortable recommending it.

The USB-C charging port is convenient, battery life and brushing power impressed, and it comes in a nice variety of colors. The sonic handset (which simply means 'vibrating' in this case) has two modes (soft and hard), a two-minute timer, and a pulse every 30 seconds to remind you to switch 'zones'. That's all most people need out of an electric toothbrush.

Under $100: Suri 2.0 Sustainable toothbrush

The Suri electric toothbrush range is built with quality and sustainability in mind. The recyclable heads are comprised of bamboo, while the aluminum handle can actually be taken apart, allowing the device to be repaired in order to reduce electronic waste.

It's also a very good toothbrush, with a powerful motor, month-long battery life, head cover for travel, an optional case with UV light for killing bacteria, and a pressure sensor to prevent you from pushing too hard on your teeth. Our reviewer awarded it 4.5 stars, claiming it "cleans up on all fronts". It even comes with a sticky-backed magnet, allowing you to easily mount it on your bathroom wall.

Right now, you can get the Suri 2.0 sustainable electric toothbrush (no case) discounted from $105 to $84 at Amazon, a 20% discount.

Under $200: Philips Soniclean Diamondcare 9000

A powerful premium electric toothbrush, the Philips Sonicare Diamondclean 9000 is packed with features most of us would never even think of, with 12 brush settings, a powerful motor delivering 62,000 bristle movements per minute, smart tooth-cleaning, coaching via the Sonicare app, a USB charging travel case, and lots more.

In our review, we said it was a "powerful, good-looking electric toothbrush with a wide array of modes and intensity settings so you can tailor it to suit you". Although we didn't think it was smart enough for the asking price, you can now get the Philips Sonicare Diamondclean 9000 two-pack at 50% off, discounted from $399.99 to just $199.99 for two brushes, charging cases, and stands. At this price, I'd recommend it if it's in your budget.
