The spring sales season is getting started, with more deals appearing. We’ve scoured the web for the biggest discounts we can find and rounded them up below.
Getting the best deal on an electric toothbrush
When electric toothbrushes are launched in the UK, they’re given an RRP (recommended retail price), but most brushes only sell at this price point for a couple of months. After this, they may be reduced by as much as half. This means that it’s quite hard to tell whether or not you’re getting a good deal as retailers can show big savings that aren’t as good as they seem.
In all of the following deals, we’ve aimed to use the amount that the brush usually sells for as the original price, rather than comparing the discount to the RRP. That means the savings you see here are real.
The price of brushes also fluctuates depending on the time of year and the retailer, so we’ll only include offers when brushes reach a price point we think is an excellent deal.
If you want more information on types of brush and useful features before you buy, check out our buying guide below the deals round-up.
The full list of discounts follows but if you’re interested in the models we rate most highly, check out our round-up of the best electric toothbrushes we’ve tested.

Top 10 Electric Toothbrush Deals
Oral-B Pro 3 3900 twin pack

The price has risen a little but this is still the cheapest way to get two of these new Pro 3 brushes, which sell for £40-£45 each. We reviewed the Pro 3 3000 and liked it a lot. It has 3 brushing modes, a pressure sensor & a two-week battery life.
Oral-B Genius 9000

As always, ignore the RRP price on the deal page (although some retailers are still selling it for £300), but this is a solid discount on an excellent brush.
Oral-B iO6 (US)

The newest iO of the bunch is also the most budget-friendly. It usually retails for around $150, so although this price isn’t nearly as good as its Black Friday discount (it was $99.97) this is still a good time to buy. We’d recommend it.
Oral-B iO7

Ignore the £400 RRP. This brush usually retails for around £200, so this is a great deal. The iO7 has the same brilliant cleaning performance as the iO9 (which is the most important thing), and many of the same features. Its OLED screen is black and white – not full colour though.
Philips Sonicare DiamondClean 9000

The DiamondClean 9000 is a powerful smart brush with enough adjustable settings that you’ll be able to personalise your brushing experience precisely. You can read our review to find out more. The Black Friday price was £129.99 and the current next best price we can find is £175 from Boots, so this is still a decent deal on one of the best brushes around.
Philips Sonicare 3100

If you’re after a Sonicare brush, the 3100 is one of the best value ways to get it – and this is a solid deal. It has an integrated pressure sensor and timer.
Foreo Issa 2

Ignore the on-page RRP as these are being sold for £119 now, but this is still a solid saving on a beautiful silicone brush. Price still varies depending on colour and All Beauty has a selection, ranging in price from around £70 to £95. Want to know what it’s like to use? Check out our review.
Oral-B Genius X

The price of the Genius X tends to fluctuate but right now, you can buy it from Amazon for £110. £90 is one of the lowest ever prices we’ve seen for this model.
The Genius X is a brilliant brush that we gave 4 out of 5 stars in our test. You can read our review here.
Where to find smart toothbrush savings
As with most things, Amazon is one of the best places to look for toothbrush deals first, especially if you look in the Deals of the Day. These discounts, also known as Lightning Deals, are offered for a limited time (often for a few hours only), or until stocks run out.
We’d recommend signing up to Amazon’s 30 day free trial of Prime, which will not only get you access to Lightning Deals 30 minutes earlier than non-Prime members, but will also get you free next-day delivery. Plus, you’ll get access to Prime Video, which you can access through your smart TV, and other benefits during your trial, too.

Types of electric toothbrush
There are two main types of electric toothbrush. First, there are mechanical brushes, which you might also see described as rotating, oscillating, pulsing, or a variation on the above. These work by rotating (or oscillating, or pulsing) the bristles on the brush head to remove plaque and clean teeth.
The Oral-B Vitality brush is one of these but most Oral-B brushes now use a combination of oscillations and sonic vibrations to clean.
The second broad type of brushes are sonic. These vibrate rather than rotate, the idea being that they hit certain frequencies that break down plaque and help to drive toothpaste between your teeth. Philips Sonicare brushes are the best-known example.
Finally, there are a few more recent brushes in a third category, but they’re much less common: ionic. We’ve reviewed the Sanyei Ion-Sei, which claims to generate ions that stop bacteria from growing in your mouth. Clinical studies have shown good results but it’s still early days for the technology.
Smart toothbrushes
More and more toothbrushes are now boasting smart features like Bluetooth and app support, with a few even claiming to be ‘AI toothbrushes’. Take all of this with a pinch of salt – but still, the companion apps for brushes can be a great way to improve your brushing technique or monitor your child’s.
Different brushes handle it in different ways, but the core functionality of most apps is to monitor where in your mouth you’re brushing the most (and the least) and give you tips on how to give yourself a more thorough clean. The Oral-B Genius 9000 does this in a slightly awkward way by using your phone’s camera to monitor your brushing, but newer brushes like the Oral-B Genius X and the iO use inbuilt sensors to detect the brush’s position in your mouth.
They may even include games to encourage kids to move the brush to a new spot in their mouth to collect virtual coins or something similar, teaching them good brushing technique in an entertaining way. As you’d expect, there’ll also be all sorts of stats tracked so you can monitor your progress and how often you brush.
Other features
Even if an app doesn’t appeal, there are a few key features you might want to look for in a brush. One is a pressure sensor: this means that the brush will alert you (either with a light or a change in vibrations) when you’re pressing down too hard with the brush, potentially damaging your teeth and gums.
The next concern is a brushing timer. Your brush will alert you every 30 seconds to move onto the next section of your mouth, making sure that you’re brushing for long enough (two minutes is the total recommended amount of time) and not missing spots. Most people favour certain areas of the mouth, while neglecting others and a timer can help you break this habit.
Finally, look for brushes with multiple speeds or modes – especially if you have sensitive teeth – as these will allow you to adjust the power to suit your preferences. It’s especially useful if you’ll be sharing the brush with other family members (though please remember that everyone needs their own brush heads!).
Battery life
The battery might not be an obvious concern when it comes to a toothbrush, but if you don’t have a handy charging socket in your bathroom, it could make a massive difference in terms of day-to-day convenience. A long enough battery life will also save you from having to bring a charger with you on holiday.
Top brushes should last for a couple of weeks of twice-daily use, and we wouldn’t recommend buying anything that won’t run for at least a week. Even better, some modern brushes will charge by USB, which at least gives you more options for topping them up while travelling, and might compensate for a shorter battery life.
Replacement brush heads
There are two considerations with brush heads. First, what choice of brush heads will you get? With a big brand like Philips or Oral-B, odds are you’ll be able to choose brush heads designed specifically for whitening, gum care or sensitive teeth. With a smaller brand, you’re likely to be more limited.
Price is also a key factor. While the brush itself may be expensive, the bigger cost could end up being replacement brush heads. Again, big brands have the edge here: thanks to bulk manufacturing, they can sell brush heads for less, and you can usually find third-party duplicates at even better prices. Smaller brands like Sanyei just can’t compete here.
So before you snap up a cheap brush, make sure you won’t pay for it later when it comes to buying new brush heads.
