An electric toothbrush is not a modern invention –invented in 1954 as a toothbrush which plugged into the electrical outlet directly – and continues to be useful today.

Standard electric toothbrushes work by using fast, bristle motions over the teeth and gums, in either a circular or back and forth motion, to provide the cleaning action. An internal motor within the brush provides the power to move the brush head during use.

Modern electric toothbrushes come with internal rechargeable batteries or with an option to replace batteries periodically. Originally toothbrushes used metal connectors and sat in a base to recharge, but now they use induction charging which makes it simpler to charge them. The toothbrush sits in the base and charges from that position, rather than needing to be precisely slotted into place.

Oral-B Pro 2500 Electric Toothbrush
  • Oral-B 3D technology movement: Round toothbrush head oscillates, rotates and pulsates to break up 100 Percent more plaque vs manual toothbrush. (Item package may vary)
  • Protect your sensitive gums: Visible gum pressure sensor reduces brushing speed and alerts if you brush too hard
  • From day 1: Gently whitens your teeth from 1st use by removing surface stains and plaque
  • Two cleaning brushing modes: Daily clean and gum care
  • Oral-B is the No. 1 brand: Used by dentist professionals and approved by the Oral Health Foundation

The number of oscillations by an electric toothbrush falls into the 2,400 to 2 million range per minute. The oscillations are barely audible, but the motor is likely to emit a sound during use.

Most electric toothbrushes are now sonic toothbrushes, with the technology has improved since the early beginnings of the product in the 1950s. Sonic brushes use a sweeping motion, which is different from other types. The number of oscillations is between 12,000 to 24,000, and there are models with 24,000-48,000 motions each minute. The sweeping motion is wider than with standard electric toothbrushes. Sonic toothbrushes are perceived to be an improvement over earlier models.

Ultrasonic toothbrushes are less common but are the next step up in innovation. Initially, the product only used ultrasound, but they now use ultrasonic waves on a 20,000 Hz frequency. Ultrasonic cleaning tools are authorized to operate at a 1.6 MHz frequency in the USA, which creates 192 million movements every minute.

The ultrasonic effect works by using sonic waves to break up bacterial chains present on the surface of the tooth and up to 5mm below the gums too. The vibration shakes the chains of bacteria from staying connection and destroys them. A newer sweeping motion has also been incorporated into some sonic toothbrushes because this has been found to get rid of remaining stubborn bacteria and bits of food.

The more advanced ultrasonic toothbrushes have not taken off in the marketplace as much as their sonic counterparts because the technology is patented which has prevented it being marketed widely. Ultimately, several major companies now focus on oral care products to compete with their lines of sonic electric toothbrushes.

Oral-B Pro 2500 Electric Rechargeable Toothbrush Review

Oral-B makes some of the best quality toothbrushes on the market. The brand is often recommended by dentists and the selection of products includes some of the most advanced features and specifications available right now.

But of course not everything the company puts out is a winner, so how does this more basic offering stack up?


As with any electric toothbrush, the Pro 2500 offers up to 100% more plaque removal than a manual brush. It also promises to provide healthier gums in just 30 days thanks to an ability to sense when you are brushing gum and to slow down and engage a lighter setting accordingly/warn you that you are brushing too hard. This is a great feature for anyone that is getting a little ‘long in the tooth’ (in the literal sense).

Meanwhile, the device also comes with two separate modes for different types of cleaning and the Oral-B’s popular round-headed design. The company is so confident that it suggests you’ll get the benefit of a whiter smile on day one!

Closing Comments

While this brush lacks some of the most advanced features seen with other Oral-B brushes like the 9000, it still brings some of the most important benefits from those models and makes them accessible to more people. It’s not as premium but it’s still highly convenient and a great entry point for anyone that is interested in taking better care of their teeth.

Fairywill Electric Rechargeable Toothbrush Review

It pays to be wary of products on Amazon that don’t have a brand name but rather just describe their function. This product is certainly guilty of that, but before you write it off, consider the benefits that it has to offer – which are actually quite impressive.


This brush promises to offer the same level of cleansing that you might get from a dentist. While that may or may not be true depending on your dentist, it is certainly true that the 35,000 micro-brush per minute cadence will provide a great level of cleaning.

Depending on the precise benefits you’re looking for, that might vary somewhat as there are three different modes (clean, soft and massage). Other benefits include a flexible head which further helps to reach those difficult-to-get-to spots, and tooth-waved bristles made using Dupont nylon in order to support the ‘topography’ of the teeth. In other words, it once again helps to reach the more difficult areas.

Closing Comments

This is a very good toothbrush considering the brand is lesser known and its various features and specifications certainly make for an impressive product on paper.

That said, this does lack some of the most advanced features that you might find with the competition. The modes are limited (only two are really useful) and the lack of any tracking etc. might be a shame for some people.

That said, if you just want a solid clean, then you could do a lot worse!

Philips Sonicare EasyClean Electric Toothbrush Review

The Sonicare toothbrush promises to remove more than twice the amount of plaque than a regular toothbrush and adds sonic technology that can help to get even better results than much of the competition.

But is this the right electric toothbrush for you? Let’s dive in and find out.


Switching to an electric toothbrush is always going to bring immediate benefits for anyone. But that is not to say that all electric toothbrushes are made equal and if you want more from your brush, then the Sonicare EasyClean is a good way to go.

That’s thanks to the titular sonic features that help to break up plaque and dirt from between the teeth and along the gum line. This is safe for dentures and braces and isn’t hard on the gums, but it provides a more thorough clean than your standard, throwaway electric brush.

There’s also a quick-start program, which promises to help you get used to using an electric brush if you’re not familiar.

The Sonicare EasyClean has a two-week battery life on a single charge. That makes it easy to bring with you on holiday without needing to worry about finding wall sockets.

Closing Comments

The Sonicare is a great toothbrush from Philips that really benefits from its sonic features. However, it isn’t quite as ‘smart’ as some of the brushes from Oral B, so you may want to consider those if you’re looking for a little more guidance.

Philips HX6511/50 Sonicare EasyClean
  • Patented sonic technology. Includes 1 x Optimal Gum Care brush heads
  • Slim handle for comfort and maneuverability
  • Removes up to 2x more plaque than a manual toothbrush
  • 2-minute smarter helps ensure recommended brushing time with 30 second interval timer

Oral-B Smart Series 6500 CrossAction Electric Rechargeable Toothbrush Review

Your oral hygiene is incredibly important not only for the way you look and those white smiles but also your health as a whole. Our mouths are the gateways to our bodies and if we don’t look after them, we risk inviting a wealth of unwanted visitors in the form of bacteria, germs, and viruses.

That’s why it’s important to invest in a good toothbrush. And the Smart Series from Oral-B certain fit that mold.


Like the 9000 model, the Oral-B Smart Series 6500 offers up to 100% more plaque removal, in part thanks to the round head brush.

But any round-headed electric brush can offer as much. What puts the top Oral B products ahead of the pack, is an ability to protect gums by altering the pressure automatically, the ability to guide your movement and make sure you attain 100% coverage on every brush, Bluetooth charging and more. The Wireless SmartGuide promises to offer tips and encourage the best habits, while an included travel case and charger make it easy to continue those good habits on the road.

Closing Comments

The 7500 CrossAction is Oral-B’s second most impressive toothbrush, right behind their flagship device the 9000. You’re still getting a whole lot of toothbrush here though, which promises to help prevent plaque and decay while improving whiteness, hygiene and more.

For those that care about their teeth, this is a great investment.

Oral-B SmartSeries 6500 Electric Toothbrush Designed By Braun
  • Up to 100 Percent more plaque removal. Round head cleans better for healthier gums
  • 5 BRUSHING MODES: daily clean, pro clean, sensitive and whitening

Oral-B Genius 9000 Electric Rechargeable Toothbrush Review

The Oral-B Genius is one of the most advanced ‘smart’ electric toothbrushes on the market. It comes dentist recommended and is a worldwide recognized brand. It also packs a lot of features to ensure the most thorough clean and the most day-to-day convenience.


The Genius claims to offer up to 100% more plaque removal than manual brushes. It uses rounded heads in order to clean gums better and to offer visible improvements within 30 days. In our tests, it really does seem capable of reaching crevices and gaps between teeth and around the gums that other brushes couldn’t quite get to.

The company also promises 100% brushing coverage. It achieves this by guiding your hand as you brush, based on ‘position detection’. In other words, it can tell where you’ve been based on the angle, position, and trajectory of the handle and then recommend spots you’ve missed. This is a huge benefit for anyone that tends to brush using the same pattern regularly, perhaps unintentionally neglecting entire areas of their mouth or specific teeth. The brush even has six different ‘modes’ which offer everything from whitening to desensitizing, to gum care!

In terms of convenience, the Genius 9000 will never run out of battery thanks to a clever travel case. This can charge your toothbrush and your phone simultaneously, so there’s no more fighting over outlets with your partner in the hotel room!

Closing Comments

Overall, this is the toothbrush that does everything. It’s a great investment for those that care about their oral hygiene.

What’s Included with The Best Electric Toothbrush

Each rechargeable electric toothbrush comes with a toothbrush unit, one or more affix-able heads, and a base to perform the conductive charging. The higher-end models sometimes include a USB charging option for frequent travelers.

A convenient travel case is provided to ensure the toothbrush stays hygienic.

Depending on the toothbrush brand, there are replaceable heads that snap on with different designs (standard toothbrush rectangular head, circular head, etc.) included in the package.

An oral care guide is usually provided in the box too.

What to Know Before Making a Purchase

For most consumers, they’re choosing between 2-3 major brands in the marketplace. Up to 6 times more plaque gets removed with an electric toothbrush, and less decay is found following prolonged use. More advanced models from the major brands tend to offer improved cleaning heads and multiple cleaning modes (clean, polish, sensitive, gum care and white.)

Some models come with a smart timer feature that times the use to ensure people brush their teeth for long enough to get the most benefit from it.

Ergonomic handle designs make it easier to grip the toothbrush during its operation.

Does the unit have a battery charger LED indicator letting the user know when it is time to recharge? Battery life is up to two weeks for individual users.

Other Considerations

The curved bristle heads can reach different parts of the teeth and gums than a flat surface brush. Whether choosing to use a circular bristle head or a more rectangular one, look for heads that have uneven surfaces for a better overall teeth cleaning experience.

Best Brands

  • Oral-B is a brand that is synonymous with oral care or oral hygiene. Part of the P & G Group of companies, it makes sense that they have a fully electric toothbrush line, to complement their other products. They also have battery-powered toothbrushes for times when a power supply isn’t readily available.
  • Phillips makes their Sonicare electric toothbrush range. The company has been involved with these products for decades now.

What Consumers Say

Taking a look at consumers’ reviews, these are a few of the opinions most often voiced by buyers:

  • Smaller brush heads: People with smaller mouths prefer the small, circular brush heads. Individuals who can accommodate a larger brush head usually prefer this option.
  • Drop-able: Electric toothbrushes have little protection from accidental drops. The toothbrush slipping in the sink is probably okay, but should it fall to the floor; this will cause severe damage.
  • Replacement Heads: The heads should get replaced either every three months or when the bristles are starting to bend and be less effective. There non-branded compatible alternative heads, but the quality is usually suspect.
  • Hard bristles: Some of the supplied default brush heads feature hard bristles. For anyone who finds they use soft bristle toothbrushes, there are replacement heads available with softer bristles to protect the gums more.
  • Waterproof: The toothbrush is sealed and waterproof. Units that use replaceable batteries are also waterproof after the battery flap is closed properly.
  • Pulsing handle: Some models have a timer that pulses every half minute to let the user know to move the head to a different part of the mouth. For anyone whose dentist tells them that they’re not brushing their teeth properly, these models are a good choice.
  • Pressure sensors: Advanced models feature sensors that stop pulsing to indicate the user is pushing down too hard when brushing.
  • Noise: Electric toothbrushes are noisier than first-time users would probably expect.
