Sonicare fake brush heads

Sonicare fake brush heads 1

In the technologically advanced world in which we live, it is now easier than ever to copy something that someone else has done.

Fake or counterfeit products exist in all different product lines from alcohol to clothing; toothbrush heads are not an exception.

Generally, the intention of the creator or seller of the fake/counterfeit is to make larger profits from selling a very good copy rather than the original.

Typically fakes or counterfeits can be produced cheaper and sold cheaper but often lack the quality, reliability and benefits of the original. This is something that was highlighted by U.S. Customs and Border Protection officers as they seized 20,000 counterfeit Oral-B brush heads in November 2019.

It can be very difficult to spot what is fake and what is genuine, but there are a few signs to look out for which I explain below.

I must also point out that there is a difference between fake/counterfeit and compatible third party replacement brush heads.

Fakes will normally have all the same or almost identical characteristics to the originals, including manufacturer branding and in all intents and purposes appear to be real. 

The third party, compatible brush heads will not have the Sonicare brand or logo on the head or the packaging. There should be nothing to imply it is made by Philips Sonicare, there should be some more obvious differences to an original. However, that third party head will fit to and work with a Sonicare toothbrush.

That said, there is a bit of a blurred line between these as even though some brush heads are sold as ‘compatible with’ Philips Sonicare and may not be a true fake, the colors and head design look so similar that it is easy to believe or misinterpret them to be genuine.

Where to buy authentic Sonicare brush heads online

Just before I go into more detail into how you can spot a fake Sonicare brush head, I would like to point out where you can buy them online, safe in the knowledge that they are the real deal.

I often link to various brush heads throughout my reviews, but I also have a post that compares Sonicare brush heads. In this post, I link to the various brush heads on Amazon. These are official Philips Sonicare brush heads, so if you buy these you can be sure that they are not fake or replica.

You will also find other reputable retailers stocking these too, including Walmart, Target, Walgreens and more.

How to spot fake Sonicare brush heads

The good news is that the number of fake brush heads available for Sonicare, on the whole, would appear to be less than with the likes of Oral-B.  Check out our fake Oral-B brush heads article for more info.

Many retailers and online marketplaces have cracked down on the sale of counterfeits and even on the high street, things have improved over time as organizations like trading standards are getting better at checking and closing down potentially dangerous counterfeit sales operations.

As I mentioned previously though, even those that are sold as compatible with rather than being the real deal can easily be considered the real deal unless you are a bit conscious of what to look for.

We can be easily led into believing we are buying the real thing when it is, in fact, a fake.  At times, many of us will knowingly buy the fake as there is a cost advantage to doing so.

Most of us have been there or know someone who has, there can be one major advantage, cost.  Sadly there are often disadvantages such as quality.

Which one are you going to buy?

When products are in demand and there is a big market for fake versions of the original. Some people choose to take advantage of this and the only loser is you as the buyer.

Why spend $500 on that lovely Michael Kors handbag you have seen in your local department store when you can get apparently the same one for $50 from a guy at the market.

£$100 for a Ralph Lauren polo shirt; but just $15 for the same thing from a small shop you found on vacation.

Which one are you going to buy?

The same goes for electric toothbrush heads.

Long term, purchasing a fake can lead to problems or disadvantages that mean we wish we had bought the real/official product.

I am not saying do not buy fake or counterfeit, it is your decision, but I do not endorse it and always advise purchasing the real thing.

When it comes to your electric toothbrush and Phillips Sonicare replacement brush heads, DO NOT let yourself be led or fooled into purchasing a fake or replica – know the differences.

Real vs fake/replica Sonicare heads

Those who have mastered the fake/replica brush head will have got their production spot on and you would have no reason to actually question whether they are real or not.

However, brands try to be one step ahead and if you know what to look for you might just protect yourself from lower grade products.

Sadly, you often can’t complete the inspection of brush heads until you have purchased them and are in a position to open the packaging, but even then you might have grounds for return or wish to take action if you believe they are fake.

Later in this post, I list the differences between fakes and originals, but before I do, here are a couple of pointers to consider even before you make a purchase that may help you avoid falling victim to the counterfeit.

  • Purchase from only a recognized and reputable store or online retailer.

Do not purchase from Bob at the market or off eBay unless you are sure that what you are purchasing is the real deal or you are happy with your decision and happy to pay the price of using a copy or fake.

Buy from big name stores, like Target, CVS, Walmart and Amazon. These have policies, and regulations that reduce the chance of fakes or replicas being sold. These big name stores generally work direct with the real manufacturer.

  • If the price is that much cheaper, there is likely a reason for it.

If your local big named store is selling the brush head you want for $20 per pack but Geoff’s cosmetic market stall has the same product for just $5, question why. How is it there is such a price difference? How can Geoff sell it so much cheaper when it is normally the big name stores that can negotiate the discounts.

  • If you are being offered more for less, there is likely a reason for it.

Is there a 3rd party seller on Amazon or eBay offering your 20 brush heads for $20 when Amazon or a reputable eBay seller is selling just 8 for $20? If so, good chance they are fake as the production cost is less and it is possible to sell at this price whereas it is not for an original.

  • Is the pack size different

Original Sonicare heads are normally sold in packs of 2, 3, and 4.

These are the typical pack sizes. Be wary of other pack sizes, particularly greater than 4. Sometimes larger, genuine packs do exist, but they are less common. Sonicare does not sell heads in an individual pack (just 1 head), as this could be an indication that they are fake.

  • If the deal seems too good to be true, it probably is.

Consider the deal as a whole.  Does the price, product, reviews all sound too good to be true and you seem to be getting the bargain of the century?  It is usually an indicator that something is not quite right.

How to tell the difference between an original Sonicare brush head and a fake

The following are a list of known differences between a genuine, Philips Sonicare manufactured brush head and counterfeit/fake/replica brush heads.

PLEASE NOTE: The differences highlighted are only a guide and are designed to alert you to possible fakes.  Detailed research has been completed and we understand the following to be very helpful in telling the difference. For confirmation of counterfeit products, speak to Philips Sonicare who can offer a more detailed explanation, insight and inspection of such.

Not all fakes will exhibit these faults or flaws, but as a broader rule, a fake or copy will show one or more of these identifiers.


  • Packaging language
    • The writing on the packaging will usually be in English.  This may vary if your country’s primary language is not English.
    • Receiving packaging in any other language, particularly Chinese- if you are not in China, should act as a trigger for you to investigate further.
  • Packaging quality.
    • Is the plastic fairly sturdy or really flimsy?
    • Is the packaging sealed and well aligned?
    • Is the packaging plastic at the front adhered to cardboard on the back?
    • Are printed materials clear and legible with strong ink colors?
    • Originals will come in a hard blister pack plastic that you normally need a knife or scissors to cut into.
    • Originals will come with an inner cardboard sleeve that had key information on it with Sonicare/Philips branding with strong colors and well printed.
    • Quite often the original will come with some additional plastic cover on or over the head even inside the packaging, like a travel cap.
  • Barcode
    • The barcode for the item is on the cardboard inner sleeve, possibly in the form of a sticker, but is not attached on the outside.

The brush head shaft

  • The plastic color
    • The brush heads is usually white in color.
    • An original is generally a brighter, gloss white plastic.
    • A duller or muted white may be a sign of a fake.
    • There will be no colored ring (other than white) at the bottom of the brush head.
  • The Philips Sonicare logo will not scratch off.
    • The Sonicare logo on a fake brush head will often be lighter in color and can be scratched off with a fingernail.
    • On an original, the grey/white paint will generally be darker in color and should not scratch off with a fingernail.
    • Under the branding is a square with a grey outline.
  • A circular impression
    • A small circular and noticeable indentation on the back of the brush head shaft, about one third of the way to half the way up should be present on a real head. This should be a small impression, a deep impression may be a fake.
    • A fake may have this lower down or in the impression may not be a circle.  If there is a dot in the middle of the circle it could be a fake.
  • Dull metal and serial numbers
    • Look at the base of the brush head, you will see a metal ring that adds strength to it.
    • A real brush head is a duller silver/chrome metal with a serial/reference number that is visible.
    • Fake brush heads may be finished with a more polished metal and no reference numbers on this metal part.

The brush head & bristles

  • Fake brush head bristles do not fade in color.
    • The brush head bristles will either not fade in color at all or if it does it may take a long time to do so.
    • An original will over a 3 month period will gradually get lighter in color, with the color remaining strongest, for the longest time at the bottom of the bristle. The color fades from the top of the bristle down.
  • Tight bristle formation.
    • The bristles on the brush head will be in tight clusters and appear richer and darker in color on the real brush than the fake.
  • Fake brush heads bristles will not evenly splay.
    • All bristles will splay or not keep alignment perfectly after months of use.
    • Original brush heads tend to splay or fray a lot less with only a few bristles normally falling out of line with the tight formation.
    • If the bristles are all over the place and generally really messy, this is often a sign of a fake.

In use

  • Fitting to the brush
    • Does the brush head clip securely onto the brush handle?
    • Notice any wobbling or strange sound?
    • Is it too tight and needs to be forced on?
    • Originals will have a tight but simple fit with little movement in the brush head shaft.
  • Sore teeth and gums
    • If you use the brush and find your teeth and gums become more sensitive as a result compared to previously used brush heads and nothing else in your routine has changed, this could be a sign of a fake.

Original vs fake vs compatible with

It is worth noting that there are companies and sellers be that in a high street store or online who will not claim to be selling genuine Sonicare brush heads, but will state them as compatible with Sonicare brushes.

It is not right to suggest these are fake or counterfeit in that they are not claiming to be an original Sonicare manufactured product.

However, a large percentage will have a packaging and physical product design that is very similar to an original with the intention of you purchasing instead of an original. Just be aware.

Getting the final word on whether it is a fake

If you have concerns about any brush heads you may have purchased or be looking to purchase yourself, then it would be worth contacting Philips directly to make them aware and getting their opinion by calling: 1-800-682-7664 .

Is it legal to sell the 3rd party imitated Sonicare brush heads?

Jon Love - Chief tester
November 21, 2022

Great question Ivan. I am not a lawyer, so this is not legal advice. The answer is yes and no. You can make compatible heads that look and function similarly but are not exact replicas or don't set out to fool people into thinking they are manufacturer originals. These are legal. For example, if you made a sonic brush head called 'Ivans Sonic brush heads' and made yours slightly different somehow, this would be fine. However, if you made one identical and used the Philips Sonicare branding then this is likely illegal.

Hi Jon, I wanted to inform you that the Philips Sonicare Value Edition Replacement Electric Toothbrush Heads do not have serial numbers imprinted on the metal ring located on the base of the toothbrush head as shown in the picture of your website and as imprinted on my older ProResults toothbrush head. I purchased a 5pk of these Value Edition toothbrush heads on, which is sold by Target themselves and not a private seller as can be done on other retailer websites. I purposely purchased them on and from to avoid fakes. When I received them, I inspected them and they did not have the serial numbers on the metal ring at the base of the toothbrush head. Instead, there was a serial number printed just below the "C1" marking on the side of the toothbrush head. Thinking's merchandise buyers purchased fakes, I called Sonicare to verify the serial numbers were still being printed on the metal ring, which the representative said they were, although they didn't sound very confident about this. So I reported to that the brushes I received from them were fake, and returned them for a refund which I have received. I then purchased another Philips Sonicare Value Edition Replacement Electric Toothbrush Head - 5pk from the official Philips Sonicare website, I just received them today, and am totally surprised they look exactly like the brushes from -no serial number on the metal ring at the base of the toothbrush head and a serial number imprinted on the side just underneath the "C1" brush designation. And I kept my receipts from and as proof of purchase. I have no idea if this applies to their other toothbrush heads, but I find this incredibly frustrating, confusing and irresponsible. Not only are their reps giving consumers the wrong information, but they are making it hard for consumers to know where they can purchase legitimate products. From now on I will only purchase these toothbrush heads from the website to make sure I receive a genuine product, but I don't appreciate the inconvenience and possibly higher cost this will cause me. Thank you for your hard work and wonderful website, and I can provide you with pics if needed. Best regards.

Thanks for the comment and the information. I understand the inconvenience and frustration this must have caused. As you will no doubt be aware Philips can and do change things from time to time and what was once a unique identifier is no longer as design and manufacturing changes. Is it possible that the heads you now have actually have a little WiFi/wireless signal on the front of them, that looks something like this, but printed in grey? Of course, many of these things can be used as a guide but can't always be relied on 100%. In theory, should be a reputable outlet and the likelihood of fakes from here should be low. Of course, direct from Philips is best but more expensive. I think in future you should be ok to buy from Target.

Hi Jon, Thanks for your reply. And I just checked my Philips Sonicare Value Edition Replacement Electric Toothbrush Heads and there is NO WiFi/wireless signal imprinted anywhere on them as shown in your picture link. These brush heads were actually cheaper from Philips than from Target due to a 15% discount code so all in all I'm happy with my purchase. With the exception that my Sonicare FlexCare Plus toothbrush handle just died. I purchased it in 2015 and am sure it died because I used it in the shower and water finally got into the handle, as evidence by seeing condensation bubbles in the green charging window. So I am now searching for a replacement and am really surprised how expensive these new models are. Be well and take care.

Labeled as Sonic replacement brush heads.

Just bought fakes off of Ebay. After rereading the posting I see the seller avoided claiming that they were genuine Sonicare brush heads. The claims that were in the ad talked about similar features to the real product ie Color changing bristles to indicate replacement time, diamond pattern. The ad used close up shots of the heads to imply a large surface area when in fact the fakes were tiny by comparison. Only one third in size and bristle count, like the ultra tiny brushes used for infants. I did get 8 for $12, that should have been a red flag.

Why do 3rd party brush heads exsist?

Jon Love - Chief tester
October 2, 2020

They exist Marko to give users more choices often at more affordable prices. It is the same for many things in life. There are the major brands that command higher prices often due to product quality, reputation etc, then you have the lesser known, but still valid choices that offer benefits, commonly price.
