Our Verdict

The Oral-B Guide is an Amazon exclusive product.

The Guide offers an innovative and fairly practical combination of electric toothbrush and accessory (Oral-B Sense) that helps encourage you and me to brush better.  

The difference here is that Amazon Alexa is built in.

I like the concept and certainly back the principles behind why it exists.

If you are very keen to have Alexa in the bathroom and own a top of the line toothbrush that helps guide you, then this is ideal.

Unfortunately, for most, it is an expensive solution to the problem it tries to assist with.

The 3 BIG questions about the Oral-B Guide

If you are short of time, the answers to the following 3 questions should let you know all you need to about the Oral-B Guide.  If I have missed something, let me know in the comments.

If you want more detail, you can read my full Oral-B Guide review further down the page

1. Is there anything drastically wrong with this toothbrush?

No, there is definitely nothing drastically wrong with this toothbrush.

It is a very capable brush that cleans the teeth well.  It does offer more than what the majority of us actually need.

However, Oral-B Guide is about more than just the toothbrush itself.

2. Which other brushes should I consider?

For those wanting a basic, no nonsense toothbrush that just works, the Sonicare ProtectiveClean 4100 is my recommendation.  It has the essential features without a hefty price tag. 

If you particularly want an Oral-B brush, then it has to be the Pro 1000.  You don’t get the same guidance, but with a bit of self discipline, you can still learn the correct technique to brush your teeth.

If you want the latest and greatest technology with all the features possible, then the iO from Oral-B should be considered.

Or if you really don’t know where to turn, our list of the best electric toothbrushes will point you in the right direction.

Oral-B Guide Review (Amazon Alexa Enabled) [USA]

And now for a bit more detail…

According to Oral-B, 70% of us think we brush our teeth the way the dentist wants us to, but the reality is that only 20% do.

For many years the company has been working on different approaches to make it easier for the user to make improvements in our tooth brushing routine at home.

Oral-B Sense is one of the newest approaches.  It uses color changing lights built into the toothbrush charging stand as well as a free smartphone application to encourage people not only to brush for the right amount of time, but to achieve the best clean possible.

The Oral-B Guide being reviewed here has Sense technology built-in and it has Amazon Alexa included as well.

What is Oral-B Sense & Guide?

I feel it is very important to really explain what Oral-B Sense is and how it relates to the Oral-B Guide, the product I am reviewing here.

Oral-B themselves describe ‘Sense’ as a connected brushing system designed to improve your oral health.

Or another way they describe it is ‘like a fitness tracker for your mouth’.

What this actually means to you and me….

Oral-B Sense is a physical product made up of several components.  An electric toothbrush, a special charging stand and a smartphone application.

The premium electric toothbrush is what you use to clean your teeth and gums.  As you use it, key data is transferred wirelessly, via Bluetooth to the charging stand for the brush.

This stand is more capable than a typical charger.  It has 4 lights around the edge.  These lights are designed to relate to the 4 sections of the mouth, known as quadrants.

During a typical 2 minute tooth brushing session, the idea is you brush each quadrant (upper right, upper left, lower right and lower left) for 30 seconds at a time.

When in use, these lights are lit, with a white light, showing you which quadrant you should be brushing and allowing you to easily see when you should move from one quadrant to another.

Once all 4 sections of the mouth are cleaned, they turn green.

And, if at any point you brush with too much pressure, the lights on the stand turn red, alerting you to reduce the pressure.

Once your teeth are brushed and the toothbrush returned to the charging stand, the data collected is transferred securely to the cloud via WiFi.

An application on your smartphone is then updated with this data  and any guidance necessary is pushed to you via a notification on your phone screen. You can learn from this guidance and review the data collected, so that over time you brush better.

All 3 of these things (toothbrush, charger and smartphone) work together to act ‘like a fitness tracker for your mouth’.

Got it?

So, that is Oral-B Sense.

Now, imagine if you made the charging stand a little larger, included a speaker, made it water resistant and added Amazon Alexa….

This is the Oral-B Guide.

The Oral-B Guide is the Oral-B Sense product with Amazon Alexa essentially bolted on.

You get all the same benefits of Oral-B Sense, but now you can do all the things you would with an Amazon Alexa enabled speaker.

So when brushing your teeth, you can now listen to music, control your smartphone home and more.

I hope that makes sense (excuse the pun).

The following promotional video will likely help piece this all together.

A final note thing to be aware of is the toothbrush that is included in the box.  It is an Oral-B Genius Pro 8000.  This explains why Oral-B mentions ‘Genius’ within their marketing materials and on the box for the Guide.  

Genius is a range of toothbrushes from Oral-B.

The Genius Pro 8000 can actually be purchased separately, but the box contents and features are different.

With Oral-B Sense and Guide, the Genius 8000 has been configured to work differently.  You don’t get all the same position detection functionality with the Guide setup as you do if you bought the Genius Pro 8000 separately.

What’s in the box?

  • 1 x White Oral-B Genius Pro 8000 electric toothbrush
  • 1 x Amazon Alexa enabled smart charger base
  • 1 x CrossAction brush head
  • 1 x Quick start guide
Contents of the box of the Oral-B Guide

Pro & Cons

Here are what I consider to be the pros and cons of the Guide from Oral-B.

The Positives

  • Concept of education – The way in which Oral-B has implemented the Sense technology is smart. It is easy to see and follow. It is all founded on the right principle of helping encourage longer and better brushing.
  • Smartphone app – Clean, well thought out app which isn’t too overbearing in the amount of data it displays.
  • Multiple cleaning modes – The additional modes may bring benefits for some.
  • Built-in timer – Encourages brushing for the correct amount of time.
  • Pressure sensor – Be alerted when brushing too hard via a red warning light on the handle and on the charging stand.
  • Amazon Alexa built-in – Play your favourite music, control your smart home, get reminders and more whilst completing your essential oral care routine.
  • American Dental Association (ADA) approved — Passed strict lab tests to achieve ADA and American National Standards Institute-approved dental standards.

The Negatives

  • Over-engineered solution – A potentially over complicated system to solve a relatively simple problem of insufficient brushing time and poor technique.
  • Different app to other brushes – The Guide requires ‘Oral-B Connect’ app which is a new app, different to the standard ‘Oral-B’ app applicable for all other Bluetooth enabled brushes.
  • Accessories – Limited box contents. Lack of replacement brush head or a travel case that could add value and be useful to owners of this solution.
  • Price – Expensive solution that is out of an affordable price range for many, limiting the potential impact this product will have.

Design, usability, clean & general use

The Oral-B Guide smart brushing system comes packaged in a fairly conventional box that clearly highlights the fact that Alexa is built-in and that included is a Genius toothbrush.

As I mention in the section ‘What is Oral-B Sense & Guide?’ unless you are very familiar with Oral-B brushes, highlighting that this is a Genius toothbrush probably does very little, if anything, it just confuses.

In short, it is one of the top of the line models Oral-B offers.

Oral-B Guide box

A card inlay inside the box calls out key features and gives a QR code to scan to download the app.

There isn’t too much plastic which is good to see, but there is also a lack of useful accessories.

I have listed what you get in the box above, but the 2 main parts of interest are the handle and the smart charging stand.

The handle is not quite a perfect cylinder shape. It is slightly thinner to the rear than it is to the front, which helps give a comfortable handle shape to hold onto.

At the top of the handle is the metal shaft to which the interchangeable brush heads slide on and off, more on those shortly.

Below this is the customisable LED SmartRing come pressure sensor.

The 360 degree ring can be lit 1 of 8 colors of your choosing.  It remains this color when the brush is in use, unless the pressure sensor is activated, at which point the light turns to red.

The pressure sensor helps prevent you or me from doing lasting damage to the teeth.  You don’t need to scrub the teeth with lots of force.  So if the brush detects too much pressure, the system alerts you by turning on the light, but also slowing the brush motor and changing the sound the brush produces.

Pressure sensor on Oral-B Genius handle

You will also see the lights on the smart charging base lit red too.

Once the pressure is relieved, the light goes out and the motor returns to full speed.

Running down the length of the handle is a long rounded rectangle panel that is silver/platinum colored.  Within this are the main controls and icons.

In the upper third of the panel is a similarly shaped yet smaller rubber panner that is home to the power button and cleaning mode button.

Below this are icons for the different cleaning modes, well 5 of the 6 available anyway. Daily Clean, the default and go to cleaning mode has no icon. Why?! It is just odd and confusing as it looks like there are only 5 cleaning modes, not the available 6.

Oral-B Genius toothbrush part of Guide package

Press the power button once to power the brush on and press and hold for 2 seconds to turn the brush off. The button requires a firm push, meaning it is difficult to accidentally power on or off.

To change the cleaning mode it is a case of pressing the cleaning mode button (downward facing arrow) under the power button.  Continue to press this until the desired cleaning mode is reached and the indicator illuminated. Each cleaning mode is backlit with a white light when selected.

You must turn the brush on before being able to change the cleaning mode.

In the lower third of this front panel is a Bluetooth icon, a battery icon made up of 3 bars and then finally the Oral-B and Braun logos.

On the rear of the brush is a contoured white rubber grip which assists when holding the brush for grip, especially when wet.

Orla-B Guide toothbrush laid on back

The base of the brush is sealed but has a recess into which the prong on the charging stand fits to charge the brush.

The Genius toothbrush is water resistant, so a rinse under the tap, exposure to moisture such as toothpaste and saliva is all fine.

Sealed inside the handle is the rechargeable lithium-ion battery and the electronics that make this toothbrush so capable.

The Genius toothbrush cleans the teeth exceptionally well.  It is clinically proven and has been awarded the American Dental Association’s seal of acceptance.  Part of this is thanks to the small round, brush heads that Oral-B use.

Supplied with the Oral-B Guide is just 1 x CrossAction brush head.  This is just one of a range of heads available from Oral-B.  Our guide to Oral-B brush heads explains more should you care to take a look.

These heads offer an oscillating rotating and pulsating motion.  This is a proprietary technology that helps clean tooth by tooth reaching areas that are often missed.

The dynamic 3D movement helps adapt to your teeth as it oscillates, rotates and pulsates to break up and remove up to 100% more plaque than a manual toothbrush.

I certainly have no complaints on how well it cleans the teeth.

Oral-B Guide toothbrush laid on right side

Remember to replace your brush head at least once every 3 months or 90 days if not sooner. 

Blue bristles on an Oral-B brush head will fade in color as it ages, giving you another visual indicator that it is time to replace the brush head.

The 6 cleaning modes available on the 8000 are:

  • Daily Clean
  • Gum Care
  • Sensitive
  • Whitening
  • Pro-Clean
  • Tongue Cleaner

I explain how each of these differ in detail in this post on Oral-B cleaning modes.

Cleaning mode icons on Oral-B Genius handle

Whilst Daily Clean is the default mode, you can choose any cleaning mode you like based on your preference.

As I mentioned above, icons, rather than the cleaning mode names depict each on the handle.  If you want to select the whitening mode, you need to remember that it is the diamond icon on the handle that is whitening mode.

Typically each cleaning mode lasts for 2 minutes, the time dentists recommend brushing for.

The Genius has a professional 2 minute timer and 30 second pacer (quadpacer) built-in.  

The principle behind tooth brushing is that you spend 2 minutes brushing the teeth in total, this includes all surfaces.

To ensure you give equal attention to the teeth, you spend 30 seconds cleaning each quadrant of the mouth.  Those quadrants are, upper right, upper left, lower right and lower left.

When you have brushed all 4 quadrants for 30 seconds each, you will have brushed for a total of 120 seconds/2 minutes.

Because the Genius has a timer and pacer built-in, what happens is that as soon as you turn on the toothbrush, the 2 minute timer is activated.  As 30 seconds passes a short stuttering sound is heard, the brushing sensation changes and the Smart Ringe flashes.

This is your alert to move from one quadrant to another. This is repeated 3 times.  

On the 4th occasion (2 minutes total brushing time) a long stuttering sound and flashing light indicates the end of the recommended 2 minute clean.  You can then turn the brush off.

Should you stop brushing at any point, turning the brush off, but then resuming within 30 seconds the brush will resume the timer.

Statistics tell us that the average American brushes for 45-70 seconds per day.  This is less than half the recommended total daily brushing time.

Features like the timer and pacer are designed to help encourage you and me to surpass these stats and brush for 2 minutes twice a day.

The inclusion of Oral-B Sense into the Guide, is essentially where things are taken to a new level to try and help us achieve the goal of 2 minutes of brushing.

Alexa enabled Oral-B Smart charging stand

The charging stand not only recharges the toothbrush, but it shows you via lights on the edge the quadrant of the mouth you should be cleaning.

Turn the brush on and a white light will shine in the upper right edge of the stand.  

After 30 seconds, a second white light will shine in the lower right edge, then the bottom left edge after 60 seconds and the upper left edge after 90 seconds.

Oral-B Guide Review 1

When 2 minutes have passed all 4 will flash green.

These lights illuminate/change at the same time you get the pauses in the brush head motion on the toothbrush.

The very intention of these is that they act as very clear visual clues as to how long you have been brushing for.

A Bluetooth connection between the toothbrush and the charging stand keeps the two in sync.

Oral-B Guide Review 2

The lights will even change to red, like the SmartRing on the handle to alert you when you are using too much force.

As you brush, the toothbrush handle is collecting data, like many smart toothbrushes today.  

Unique to the Oral-B Guide and Oral-B Sense enabled products is the way in which brushing data is then handled.

Bluetooth sends the data to the smart charging stand.  The stand connects to the wireless (WiFi) connection in your home.  It then securely sends this data to Oral-B’s cloud services, once you have signed up for an Oral-B connect account via the smartphone application.

For the more technically advanced, do be aware, the Oral-B Guide supports 2.4GHz WiFi only. Given this is a product launched in 2020, this is somewhat disappointing.

The Connect app on your smartphone is then sent this data, providing the smartphone is connected to the internet.

Oral-B Guide toothbrush & Connect app on phone in hand

Unlike all other Oral-B toothbrushes, there is no Bluetooth connection between the phone and the toothbrush.  With Sense, the connection is between the toothbrush and the stand.

This means you do not have to rely on having your smartphone nearby when brushing your teeth.

It also means the data is not shared in real time.  You can’t see via the app how well you are brushing at that specific moment like you can with the likes of the Oral-B iO.

Oral-B Connect is the free app that you need installed on your device.  It can be downloaded from the Apple or Google app stores.

Notifications will be generated by the app when appropriate to provide any useful tips, tricks and feedback necessary.

By signing up for an Oral-B Connect account (essential for this to function), you will too receive a number of introductory emails that are designed to encourage and educate.  They are a nice touch, and are particularly useful to new electric toothbrush users.  I do think there is scope for improvement in these though. Most particularly in the weekly summary emails which calculated that I had brushed for a total of 0:00 minutes each week during my testing period…not so!

The app logs all the brushing data so you have a record of this.  You can then review your performance yourself or share with dental health professionals.  It is all very clever.

I could talk in detail about the Connect app, but this would make the review very long. Screenshots shared below demonstrate a lot of the detail.

The whole principle of Sense and how it operates is commendable.  It does make you think and review your brushing in a way you might not have previously.

I think there is scope for improvement however. I don’t really know why Oral-B has created a whole new ‘Oral-B Connect’ app, when it probably could have just been merged into the default ‘Oral-B’ app.  2 apps on the relevant app stores is confusing. I suspect it is to do with the way in which the data is shared, via WiFi rather than Bluetooth.

Ultimately, I really do like the implementation of Oral-B Sense. 

I think it is engaging and requires less compliance like other attempts by Oral-B.  It is easier to switch to this approach than it might be to the setup used by the Genius X for example.

The bold lights on the charging stand are surprisingly obvious and really help encourage longer brushing at a glance.

Most will like and benefit from the smart charging stand. It is the app that will divide most.

It does too surprise and confuse me slightly why this approach?

Oral-B have multiple approaches, each with their own subtle differences across their range of Bluetooth devices.

Oral-B Guide toothbrush & Connect app

The Oral-B Pro 3000 and Pro 5000 have a different approach to the existing Genius Pro 8000.

Both of these are different to the Genius X.  And then there is the Oral-B iO which is implemented slightly differently again…..!

Of course, where the Guide is truly unique is that this smart charging stand actually has a speaker built-in and is equipped with Amazon Alexa.

This means that you can be brushing your teeth and getting updates such as the news, playing your favorite music, controlling your smart home, setting reminders and much more.

It certainly works.

The speaker functionality of the Guide is essentially the same as an Amazon Echo dot might be.  The difference here is this is built into the stand that recharges your toothbrush.

Oral-B Guide charing stand with Amazon Alexa built-in

The speaker quality is satisfactory for what you need it to do.  You have the choice of 12 different volume settings (controlled via the stand itself) and the loudest is good enough to be heard behind the noise of the Genius brush itself. 

I think using this as part of your morning routine is where you will get most value.

It is certainly one of the most convenient and cheapest solutions to get such in your bathroom, particularly when you consider this is water resistant, unlike most other alexa enabled speakers.

It doesn’t work only when using your toothbrush, you can benefit from Alexa at any point providing the stand is plugged in.

Of course there is a microphone built-in, but you can disable this as and when you like via a button press.

It is a novel idea.  Not everyone will need or want this in their bathroom, but if you think you could benefit from it, the Oral-B Guide is the only product to offer such.

For what could be considered a more premium brush, you don’t get many extras in the box.

Unlike the standard Genius 8000, there is no travel charging case included in the box with the Guide.  In fact there is no travel case at all.  This is a real shame and a bit of an oversight in my opinion. 

There is nothing stopping you taking the Oral-B Guide with you when you travel, be that the handle only or the charging stand also.  You will just need to find your own solution to protect it.

Rather disappointingly just 1 single brush head is provided.  It would be nice to have at least 2, if not 4 in the box for this price.

Oral-B Guide CrossAction brush head

Being an Amazon exclusive product, there is the option to subscribe to brush head refill deliveries with Amazon dash replacement services (DRS) so you get them just when you need them.

Make no mistake about it, the Oral-B Guide solution is a pleasure to use on a daily basis.

It is very capable, if a bit over engineered for some.

Failing to brush your teeth properly can lead to all sorts of problems. It might start with a bit of swelling and inflammation and discomfort but over time this can get worse and require professional medical attention that can be painful and expensive to resolve.

What Oral-B has tried to do is encourage and educate in an intelligent way that doesn’t nag or really get in the way. And because the Sense technology is core to the charging stand, there is that constant reminder that many need to brush for the right amount of time. It tries to stop oral health becoming an expensive problem.

Battery life

Personally, I see battery life to be an important factor when it comes to choosing a toothbrush, preferably I want it to last as long as possible without needing a charge. However, 95% of the time my brush lives at home within close range of the charging stand and there is no reason why it could not be charged more frequently.

Oral-B claims a battery life of 12 days from the built-in lithium-ion battery.  This is better than the likes of the Pro 1000 or 3000 by 5 days, but still falls short of the 2-3 week battery life offered by Sonicare brushes.

The actual usage time will vary from one user to another based on the amount of time you brush for and the mode used.

However in actual hands-on testing, using the Daily Clean mode I achieved 18 days of use on a full charge.  This is equivalent to 76 minutes of usage time or 36 sessions.

However, at 14 days (56 minutes/28 sessions) the battery warning icon came on and there was a noticeable slow down in the brushing speed.

Genius Pro 8000 on Oral-B Guide charging stand

There is a battery icon on the brush handle, that is broken into 3 bars.  Each bar indicates approximately 33% of power from the battery, so you get a rough idea of how much power remains in it.

At 10% a bar within the battery will flash red as will the LED ring to alert you to the lack of remaining power.

When not in use or when in need of a recharge it can be popper on the smart charging stand.

A full charge will take approximately 8-12 hours to complete.

Asit charges, the battery icon on the handle will light up every few seconds.  Once complete the light will go out.

It is perfectly safe to leave it on the charger, it will stop charging when the battery is full.

Power connecto on Oral-B Guide smart charging stand

The power supply for the stand is a proprietary power adapter for this enhanced charging base.  The power adapter has a 2 pin US plug configuration, but is rated for 100-240V.

You might have thought that this smart toothbrush relays battery information back to the Oral-B Connect app, but it does not.

Summary of battery life

  • Claimed 12 days usage based on 2 cleans a day
  • Achieved up to 18 days of use on the daily clean mode
  • Battery is built in and not user replaceable
  • Can be left on the charger
  • Takes about 8-12 hours to charge fully
  • The charging stand included in the box supports 100-240v
  • Battery status icon flashes with a white light when charging and red when battery is very low
  • No battery information within smartphone app

Price & where to buy

The Oral-B Guide is an Amazon exclusive product.  

What this means is that it could be very competitively priced, or more likely because this solution is unique the price is and will remain relatively high.

Amazon’s list price for this toothbrush is $229.

Since first being listed on Amazon, the lowest it has dropped to is $199.

This brush like every other requires replacement brush heads for each user every 3 months. Replacement heads can be purchased in packs of 2, 3, 4 and 5. 

Or one of the perks with the Guide is you can easily subscribe to replacement brush head deliveries with Amazon Dash Replacement Service.

The prices vary but are on average around $5 per brush head included. 

We like to offer up a figure for what we believe to be an average cost of ownership of this toothbrush.

Using the average cost (based on one user) and ownership over 3 years, the Guide will cost $284 or just $0.26 per day to own.

There is a good chance the brush will last longer than the 3 year period therefore making for even better value. 

Amazon clearly feels it is worth the $229 price, because it is different.  And I can understand this.

Given that the Guide is essentially an Oral-B Sense toothbrush package with an Amazon dot speaker bolted on, it is possible to gauge whether this price tag of $229 is justifiable.

Oral-B Sense + Amazon Dot speaker = justifiable or not price.

Orla-B Guines Pro 8000 part of Oral-B Guide package

Unfortunately, at the time of writing, although we know the Oral-B sense toothbrush is coming, Oral-B has yet to announce the final price. Therefore I can’t make the comparison I would like to.

But, the Genius 8000 is one of the core components within this package. This is available for purchase separately.  The features and box contents are a little different, but it can give us an idea for the sake of comparison.

With a $180 retail price, the $229 of the Guide seems reasonable given the Sense technology and the Amazon Alexa enabled speaker built in.  The speaker is probably worth around $50.

However, the typical selling price of the Genius 8000 is around $135.  Add on $50 for the speaker and we are now much more comparably priced.

But, this is still approximately a $95 premium for the Oral-B Guide compared to the 8000.  

You can purchase a perfectly good electric toothbrush for around $50.  

Even if you stretch the budget to a slightly more feature rich brush at $100, the Guide still commands in excess of $100.

Yes, the speaker and extra features may pose some value, but you simply do not need to spend the $229.  

There is barely any difference in how well a $50 or $200 toothbrush cleans the teeth.

The BIG difference here is that the Guide is helping you to clean the teeth in a way a $50 brush like the Pro 1000 doesn’t.  That is ultimately what you are paying for.

With a bit of focus you can achieve the same results from a $50 brush as you can the Guide.  You just need to learn to brush correctly and the cost to thing is nothing other than your time.

The reality is that the Guide is not an affordable price for the majority.  There are many struggling to pay rent, feed families let alone paying for oral care. At over $200 for the Guide, very few can afford to or would choose to spend this much.  

Particularly, when you consider that you can get 4 perfectly satisfactory electric toothbrushes for the same price. 

Sadly, it is likely those who can’t afford it are those that could potentially benefit most from what it offers.

I am not saying the Guide isn’t worth it.  This is ultimately personal opinion. I am just trying to be realistic about what it offers 

If you are prepared to spend and like the features and concept behind the Oral-B Guide, I actually think Oral-B’s iO Series 9 electric toothbrush is better.  You get a bit more bang for your buck.  But, you don’t get the speaker.

Whatever you choose, just be sure to shop around to make sure you get the deal you are happy with as

Please note that all prices quoted are approximates and will vary based on location, supplier and time of purchase.  These figures were correct at the time of writing and should not be relied upon as hard fact, but used as a guide during your decision process.

Summary of price & where to buy

  • Only available from Amazon.com at the time of writing
  • The retail price of $229
  • Replacement brush heads typically cost $5 per time
  • Works out at approximately $0.26 per day to own, based on 3 years of usage by one user
  • Paying a premium for the speaker and technology
  • $50 brush such as Pro 1000 cleans just as well if used correctly
  • Those who could likely benefit most priced out of getting benefits
  • Oral-B iO a better all round buy if you want a premium brush

Reliability & long term use

The Oral-B Genius Pro 8000 toothbrush that is part of this Oral-B Guide package has been on sale for a few years and is a very tried and tested product.  I personally have had one for a couple of years and it still works well.

I have no real cause for concern surrounding the reliability and durability of this brush handle.

By the very nature of an electrical product they are not faultless and a very small number will fail, but there is no reason this should put you off purchasing this.

To prolong the life of any brush giving it a rinse and a wipe down to remove grime that builds up.

The smart charging stand with Alexa built-in is a new product within the Oral-B range and is not as tried and tested as the handle itself, but again there are no immediate causes for concern having personally handled it.

Oral-B does include a 2 year warranty, so should the worst happen you have the peace of mind of knowing it will be repaired/replaced during the first 2 years of ownership.


Honestly I have mixed feelings about the Oral-B Guide.

As a toothbrush, it cleans the teeth extremely well, I have no complaints here.

As a concept of how to encourage and educate users it is very good. In daily use, it works.

The addition of Alexa is potentially useful for some to make time spent in the bathroom a little more enjoyable.

But, there are a few fundamental issues that ultimately restrict the possible success and power of good this product could offer.

Feature overload.  Oral-B are using a new feature, ‘Sense’ to help deliver long standing oral healthcare advice and information, which is commendable.  But the Genius toothbrush which forms part of this Oral-B Guide product is too feature-rich for most and the need for Amazon Alexa in the bathroom is questionable.

Price.  New technology and approaches don’t come cheap, but at around $200 this toothbrush is well outside of the price range of many people, the very people who could potentially benefit from the approach to oral care it offers.

Product range.  Oral-B’s own product range is overly confusing.  A number of brushes (I count 5) are aiming to deliver important oral healthcare education in similar but different ways, which leads to a very complex and disjointed offering.  Ultimately it confuses.  I have tested all of Oral-B’s brushes and if I’m confused, the average consumer has no hope.

I admire and applaud Oral-B for partnering with Amazon and striving to be different.  However, in trying to be innovative they have lost sight of what is most important and need to bring these concepts to much more affordable and accessible products to really help the nation improve standards of oral care.

For those on a budget, but want a capable toothbrush, go for the Sonicare ProtectiveClean 4100 or Oral-B Pro 1000.  For those wanting the best or Oral-B right now, the answer I believe is the Oral-B iO.

      • If you see pulsing green lights while brushing, congratulations! You’ve brushed for two minutes.
      • Otherwise, green lights can mean you have an incoming call. A spinning green light means your device is on an active call or, you’re on an active Drop-In on your device.
    • Purple
      • When you see purple on your device, your “do not disturb” feature is turned on.
    • White
