The majority of dentists will recommend an electric toothbrush because they’re more efficient and offer a number of features to get a deeper clean, but knowing which one to get can be tricky, especially when you start glancing at the price tags.

Top-tier brushes can be prohibitively expensive, when honestly, a more affordable option will still give you dentist-approved results without costing too much. Brushes that boast AI mouth mapping or smart analytics are simply marketing tools and most people really don’t need them. They might help you get better results, but are they worth the cost? Oftentimes, I think not.

*An electric toothbrush will supercharge your cleaning routine*

Any rechargeable brush will be better than a manual brush at removing plaque (alongside a consistent cleaning routine), meaning you can start looking at the best brushes under £100, confident that you’ll be spending your money wisely.

Once you’ve got your budget sorted, I’d recommend getting an electric toothbrush that has some key features that are essential to maintaining correct cleaning practice. First up, look for one with a pressure sensor, which will warn you with a small light if you’re pressing too hard. These toothbrushes will help teach you how hard to press on your teeth when cleaning and will protect your gums.

Read our full guides on toothbrushing techniques here.

Alongside that, a brush that has a two-minute timer will guarantee that you’re brushing your teeth for the correct length of time (you’re only cheating yourself) and removes a lot of the guesswork out of your routine. Pair all this with a water flosser and you’ll be on the right path to a healthy, happy mouth.

Now you’re armed with that knowledge, it’s time to check out the best electric toothbrushes under £100.

The Oral-B iO3 is a solid pick at this price point, offering some of Oral-B’s exceptional build quality and battery life without bloated tech features that increase the cost.
The Philips Sonicare 5300 is one of my favourite sonic brushes, offering an alternative cleaning method to Oral-B’s oscillating models that can often be kinder to sensitive gums.
I like the Oral-B Vitality for its simple, practical approach to dental care, with three cleaning modes that cater to the majority of users’ needs.

Oral-B Smart 6

Pros: Multiple cleaning modes | Long battery life | Great built quality
Cons: One of the more expensive options on the list

Oral-B has a reputation as one of the best toothbrush brands available, largely because of its oscillating head technology that allows the bristles to rapidly wrap around each tooth to clean away plaque and stuck food. There are five cleaning modes to explore on the Smart 6, including: daily clean, pro clean, sensitive, whitening and gum care. Feel free to experiment with what feels right for your needs, though I think the daily clean option is typically the right call for the majority of users.

I like the pressure sensor which shifts from green (meaning optimum pressure), white (for neutral) and red (which highlights when you’re pressing too hard onto your teeth). Using this system will teach you the perfect technique for eliminating plaque. In my testing, I enjoyed the weighty, well-built handle and its long-lasting battery, which can be recharged with the included cable. It’s also a solid option for travellers, as it comes with a protective carry case.

Suri 2.0

Pros: Eco-friendly | Affordably priced and simple | Long-lasting battery
Cons: The Suri 2.0 is better generally, but more expensive | Only has one cleaning mode

The Suri 1.0 has become one of the most popular electric toothbrushes over the last few years, offering exceptional cleaning features for a low cost, both to your bank balance and to the environment. It’s completely sustainably made, wrought from recycled aluminium and shipped to you from fully recyclable materials.

Because of this, it doesn’t boast many top-end features like multiple cleaning modes, but honestly, I don’t think it needs it. I liked the simple, no-nonsense design, with a lightweight handle that only has an on/off switch and a sensor to denote the pressure applied.

It uses sonic pulses to vibrate plaque from your teeth, reducing build-up to make it easier to brush away, and it has a huge battery, long enough for a month’s worth of twice-daily use. One thing I loved from my testing is the charging case, which has a UV cleaning light that destroys bacteria between uses. It’s also rechargeable with a USB-C cable, making it an excellent choice for travellers. Its one downside is that the newly released 2.0 edition has multiple cleaning modes and is better overall, but the current RRP is over £100, so it doesn’t quite make our list of options here.

Oral-B iO3

Pros: Three cleaning modes | Long-lasting battery | Travel case included
Cons: Handle is a bit weighty, take note

I’ve included the Oral-B iO3 in this list because it’s, pound-for-pound, one of the best electric toothbrushes available at this price point. The iO series boasts some incredibly costly models (just check out the iO10’s astronomical price tag), but the iO3 sits perfectly in the mid-range section of the industry, offering great features at an affordable cost.

There are three cleaning modes: Daily clean, sensitive, and white, which will be perfectly fine for the majority of users, and doesn’t overly complicate the process with too much choice. Each mode offers a deep clean when used with the included pressure sensor, which shows up as a red light around the neck of the brush when you’re pressing too hard. It also doubles up as a reminder to switch out the brush heads every few months.

I like this brush’s simple, no-nonsense approach to dental hygiene, and it’s one of my favourites if you suffer from sore, sensitive gums. Don’t be fooled by the high RRP, this brush is almost never sold for more than £80.

Philips Sonicare 5300

Pros: Large battery | Flexible head that adapts to pressure | SmarTimer system to guide you through your brushing technique
Cons: Rather pricey even with sales available | Weighty handle | Only two cleaning modes

My preferred toothbrush brand is Philips, because I love the Sonicare range’s potent ability to gently remove plaque and debris, while catering to sensitive gums. It uses the same sonic pulses from Philips’ top-end toothbrushes, but at a fraction of the cost. I liked the two cleaning modes: high-intensity and low intensity, that unlocks the option to blast away plaque for a more robust clean, or take a gentler approach that’s perfect for gum line protection.

The flexible head gives you more leniency with the pressure applied, but you can always use the pressure sensor that warns you when you’re being too vigorous with your brushing. The handle is rather chunky and quite heavy, but it houses the large battery that lasts for three weeks before needing a recharge. I also really like the SmarTimer system, which breaks up your cleaning session into chunks, gently vibrating to remind you to move onto a different area of the mouth to ensure you get an even brush across your whole mouth.

Oral-B Vitality

Pros: Great for sensitive gums with three cleaning modes | Long-lasting battery | 2-minute timer
Cons: Handle might be too chunky for some

One of the more affordable toothbrushes on this list, Oral-B’s Vitality Pro is a bit longer in the tooth (pun intended) than some others I’ve featured, but its age denotes a quality that makes it worth picking up in my opinion. Coming back to Oral-B’s oscillating technique, the Vitality Pro has three cleaning modes: Daily clean, sensitive, and sensitive plus, which takes greater care of the gumline while still providing good results. It achieves this with a large, round head that totally envelops each tooth, pushing the bristles into the gaps between teeth for a complete clean.

I like the overall design and simplicity here, with an ergonomic handle and potent battery. It also features a two-minute timer that splits its cleaning sessions into 30-second chunks, nudging you to move onto a different quadrant of your mouth for a complete, even clean.

Ordo Sonic +

Pros: Four cleaning modes | Three colour options available and a great overall design
Cons: No included travel case

While I’m much more concerned with the overall capability of a toothbrush, it’s worth mentioning that the Ordo Sonic + is handsome and well-designed. The slimline handle has a display that shows you which of the four cleaning modes you’re using, from clean, white, massage and sensitive.

The brush head has a little bit of flexibility to give you more freedom as you clean, but there’s also a pressure sensor to keep you on track, and a two-minute timer to ensure you’re not under-brushing. As the name suggests, it’s a sonic toothbrush, using thousands of vibrating pulses to lift plaque and remove debris between your teeth.

FAQs

How often should I replace my brush head?

General dentist advice is to switch to a new electric toothbrush head every 3-4 months. As you clean, the bristles deteriorate, losing their rigidity and quality over time. Maintaining a regular replacement schedule ensures you’re getting the best cleaning session every time you use it. Luckily, many top brands like Oral-B and Philips offer replacement head subscriptions, sending you new heads every few months, so you’re never left short.

Is it better to buy a cheaper electric toothbrush?

If you’re on a budget, picking up a more affordable electric toothbrush is much better than buying a manual brush. If you can afford to buy a spenny toothbrush, by all means go ahead and enjoy the high-end features on offer, but any electric toothbrush is better than a manual one, so keep inside your budget and stick to good brushing techniques to get the best results.

Under £100, you’ll find plenty of quality toothbrushes that offer ideal features, like pressure sensors, timers, and long batteries that are going to help you improve your dental hygiene.

How do I recharge an electric toothbrush?

I can’t tell you how many times I’ve had patients come in with a dead electric toothbrush not knowing how to get it working. Rechargeable brushes are always better than battery-powered options, as you can simply plug it in with the included charging cable or, if you’ve got a more advanced model, pop it on its charging stand to keep it ready for use at all times. All electric toothbrushes will have waterproof cables for use in the bathroom.

How do I use an electric toothbrush?

Many adults don’t know how to get the most out of their electric toothbrush, and making the jump from a manual one can be a bit of a learning curve. The technique depends on the brand and cleaning technology your brush uses.

Oral-B brushes use oscillating heads that rapidly rotate around your teeth. If you grab one of those, you should keep your brush still on each tooth at the gumline for 1-2 seconds before rotating around the biting surface for a total clean.

The alternative technology is sonic pulses favoured by brands like Philips and Ordo. These use thousands of vibrating motions to lift plaque off your teeth. For these brushes, gently glide the brush back and forth along the gumline and then the biting surface.
