Whether you're looking for an upgrade, need to replace an electric brush that's running down or if you've decided to bin your manual and try an electric toothbrush for the first time, read on.
We've hunted down the best deals available right now, and found the best prices on popular models, so you don't have to scour the web.
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. And, if you'd like to see the best tech deals we've found in all categories, see our complete guide.
When electric toothbrushes are launched, they are 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 used 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 compare prices to make sure you get the best deal available at any point.

Electric toothbrush discounts: What to look for
Here's our guide to buying an electric toothbrush.
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 tend to be less expensive and work by rotating (or oscillating, or pulsing) the bristles on the brush head to remove plaque and clean teeth.
Brushes that only rotate tend to be the least effective, so look out for ones that pulse or use counter-oscillation (moving some bristles one way, and some the other) for a better 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 examples.
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 use a UV LED that generates ions to stop bacteria from growing in your mouth. Clinical studies have shown good results but it's still early days for the technology.
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.
Most, like the new Colgate E1, also include games which make them ideal for kids. These might 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.
Even if an app doesn't appeal, there are a few other 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!).
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.
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 are offered for a limited time (often for a few hours only), or until stocks run out. They're also known as Lightning Deals.
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.
If you're in the UK, other great places to look include Argos, Currys, Boots, Superdrug, and Very. It's always worth keeping John Lewis in mind too - the company's price match policies mean you can often get the same value deal as that from another retailer, with better customer service and warranties.
