I gave this Philips electric toothbrush five stars, and it just hit its cheapest price in years
I always recommend this Philips electric toothbrush, and it’s now on sale at Amazon
I’ve tested many electric toothbrushes in my role as T3’s Home Editor, from the likes of Philips, Oral-B, Quip, Oclean and more. But the best model I’ve ever tried – and one that I always recommend to friends and family – has to be the Philips Sonicare Diamondclean 9900 Prestige.
One of Philips’ best and most premium electric toothbrushes on the market, the Philips Sonicare Diamondclean 9900 Prestige excels in many areas, although its price does dissuade people at times. But it recently got a huge price cut at Amazon, taking it down to the cheapest price it’s been in years.

Originally priced at £229, the Philips Sonicare Diamondclean 9900 Prestige is now just £179.99 at Amazon, saving you 21% on this five-star electric toothbrush. I’ve done some price-checking, and this is the lowest price the Philips Sonicare Diamondclean 9900 Prestige has dropped to since 2025.
In my Philips Sonicare Diamondclean 9900 Prestige review, I gave this brush five stars and championed its “all-in-one brush head, multiple intensity and cleaning modes, and its AI-powered app”. It’s a brush that’s hard to beat, and at this lower price, it’s one to take advantage of.
The Philips Sonicare Diamondclean 9900 Prestige has an all-in-one brush head that removes plaque, reduces stains and delivers cleaner and healthier teeth and gums. It’s lightweight, and has simple on/off controls, and lights underneath that display battery life and intensity level.
With five cleaning modes to choose from, including clean, deep clean, white+, sensitive and gum health, you can completely customise your morning and evening routines. The different modes can be selected through the app which is free to download and uses AI to deliver personalised advice, give progress reports and show coverage.
While intense at first, I found the Philips Sonicare Diamondclean 9900 Prestige to deliver a deep clean that left my mouth, teeth and gums feeling fresh and healthy. Its SenseIQ technology which senses pressure, motion and coverage also offered handy guidance without me having to use the app, and the battery life was impressive.
The only big downside I found with the Philips Sonicare Diamondclean 9900 Prestige was its price, but it’s now cheaper than ever at Amazon. This is also listed as a limited time deal on the website so you’ll want to be quick if you want to upgrade your oral hygiene with the Philips Sonicare Diamondclean 9900 Prestige.
