- No battery status
- Poor quality
The 3 BIG questions about uFunbrush
If you are short of time, the answers to the following 3 questions should let you know all you need to about the uFunbrush mouthpiece toothbrush. If I have missed something, let me know in the comments.
If you want more detail, you can read my full uFunbrush review further down the page.
1. Is there anything drastically wrong with this toothbrush?
It does not clean the teeth very well at all. Do not buy this product.
For the sake of your oral health and in particular, that of your children, stick to regular manual or electric toothbrush.
2. Which other brushes should I consider?
uFunbrush is different to a regular electric toothbrush. It is known as a mouthpiece style toothbrush.
In our article that explains mouthpiece style toothbrushes, we list a few products of the same style.
However, at the time of writing, not one has proven itself to be even close to capable of cleaning the teeth as well as it should.
Rather than considering this style of teeth cleaning device, look at sticking with the traditional manual or electric toothbrush.
They may be less fun and take longer to brush the teeth, but when used correctly they work.
The Philips Sonicare ProtectiveClean 4100 is my recommendation for adults.
It looks and feels great in the hand and has a superb battery life in addition to the built-in timer and pacer that help encourage you to brush for the dentist recommended 2 minutes. Of course, it cleans the teeth well too.

3. Where is the best place to buy uFunbrush?
https://ufunbrush.com/ is the place to buy this from.
You won’t find this in your local dentist’s office or pharmacy.

And now for a bit more detail…
Unlike the regular toothbrush that you move tooth to tooth, to clean the top, back and front surfaces, a mouthpiece toothbrush is designed to clean all or a single row of teeth at the same time.
uFunbrush is designed to clean all the teeth at the same time, but has been designed primarily for kids, in an attempt to make brushing not only more fun for the child but less hassle for the parent.
Many delays and essentially 2 years later, the first units began shipping and it is in this review that I share my opinions on the product.
Who are uFunbrush?
I don’t normally dig into the companies behind the products, but in some instances it is necessary.
uFunbrush has been subject to delays and lots of complaints by backers/buyers.
I am not a detective and the following may not be wholly accurate, but from what I glean from the delays having ordered the brush personally and the comments on the funding campaign, is that the original persons/company that came up with the uFunbrush concept has sold/moved it onto another organization.
The design and function of uFunbrush is covered by 2 patents:
- U.S. Patent # US D781,427 S
- U.S. Patent #US 10,314,679 B2
Both of these patents inventors and assignees are:
- Andrew Blank
- Jeffrey Freedman
Andrew and Jeffrey both have a number of patents to their names according to this website:
- Andrew -- https://patents.justia.com/inventor/andrew-blank
- Jeffrey -- https://patents.justia.com/inventor/jeffrey-freedman
Now, although they may be the inventors, it does not mean they are running uFunbrush as a patent can be used by others with the inventors/patent holders permission.
That said, the name Jeffrey Freedman appears on the Kickstarter campaign page several times, so it seems that he has had some involvement with the project.
Jeffrey is the president/owner of Creative Products, Inc based in Georgia USA. Based on the LinkedIn explanation of the company, it seems highly likely he and his company were involved in bringing the initial product to market.
Although it launched on Kickstarter in late 2017, I didn’t actually order it until May 2019.
It was at this time the first units were supposed to be shipping. Some 18 months after launching the physical product was ready for the public.
Despite the website showing stock in May, it was not until September 2019 that it actually shipped.
Communication was not great, emails did get answered but it took at least a week to get a reply most times or I had to follow up. To be fair, this seems to be better than what most other backers have experienced, based on comments left on the campaign pages.
I did receive communication from Ed Matthews, who is listed as a director of a now inactive company called Calvin Greenway Inc as seen here.
Calvin Greenway appears on the uFunbrush packaging that I received.
Whether they were the founding company, or not, it is not clear. Nor is it clear what relationship Jeffrey had with them.
Calvin Greenway is no longer an active company, but someone, admittedly, sporadically is replying to comments on the uFunbrush Indigogo page. So, it appears the company/brand has been sold on. Someone has taken over responsibility, but who it is not clear.
This could be some explanation for the delays and poor communication buyers and backers have been getting, but it is not really an excuse.
Whilst I cannot say conclusively, I do have concerns about the way uFunbrush is being handled/managed. It took too much effort to get simple updates from the company on what was happening. It felt like I was being told incorrect information or little white lies.
Perhaps things have/will change, but the initial impressions have not been great and I detail this for you to make your own judgement.
How does it work?
The concept of this mouthpiece style of toothbrush is new to many people and don’t be concerned if you have not previously come across it.
It is different to a regular toothbrush in that the idea is all the tooth surfaces get cleaned at the same time.
The biggest benefit is that it then takes less time to brush your teeth.
For a more detailed explanation, watch the following video.
Variants of this toothbrush
There is only 1 style or type of uFunbrush, but there are a variety of different mouthpieces/brush heads.
Unlike Sonicare or Oral-B who have lots of different brush handles and then different styles of brush heads too, uFunbrush has the 1 style of handle, but different sizes of mouthpieces.
Those mouthpiece sizes:
- U1 -- 3-5 years
- U2 -- 6-8 years
- U3 -- 9-13 years
- U4 -- 14 years +
Each is available in a range of colors.
What’s in the box?
- 1 x uFunbrush handpiece
- 1 x U4 -- 14 years+ mouthpiece
- 1 x AAA battery
- 20 x stickers
- 1 x uFoam toothpaste
- Cleans all the teeth at the same time
- 10 second cleaning cycle
- Powered by an AAA battery
- Stickers to make it fun and interactive
- Automatic power off
Pro & Cons
Here are what I consider to be the pros and cons of uFunbrush.
- Different sized mouthpieces -- Unlike other products of this type, it is not a one size fits all mouthpiece, well for kids at least. The adult mouthpiece is a one size fits all.
- Stickers included -- 20 different stickers can make the uFunbrush appear more fun.
- It doesn’t clean the teeth very well -- The cleaning action is weak and ineffective. The teeth are not clean after use.
- Flex in the mouthpiece -- The soft silicone is so flexible that it bends too easily in my opinion.
- Special toothpaste required -- You need to use the ‘foaming’ toothpaste uFunbrush offer.
- No battery status -- No way of telling when the battery will run out.
- Poor quality -- Poor design choices and easy to damage things like the cover on the battery slot.
Design, usability, clean & general use
Coming in quite a smart flip open style box, the unboxing experience of uFunbrush is far from the worst I have had, but it isn’t the best either.
The exterior of the box is branded but with limited information. It wouldn’t stand out on a shelf in a store in my opinion. But then again, it is sold online only at the moment.
On the inside lid of the box is essentially a quick start guide in color, which gives you the basic information.
I ordered the U4 sized brush head, designed to suit the aged 14 years old or above, along with the U1 brush head designed for children aged 3-5 years old.
The separate head came in a small box.
So far, so good, but I can tell you it goes downhill quite quickly hereafter.
The images best illustrate what this product actually looks like, but essentially it is made up of 2 parts. You have the handpiece and the mouthpiece.
The handpiece contains the motor, battery and electronics to function and the mouthpiece attaches to this.
An unusual shape the handpiece is, it is actually a little slimmer and lighter than I anticipated.
Made of white colored plastic, central to the handpiece is a cylindrical part that houses the removable battery.
To one side of this central battery compartment is a largeish flat panel with the uFunbrush logo to which the provided stickers attach.
On the other side of the battery compartment is a narrower rounded rectangle sort of neck to the handpiece that has a grey power button on it.
The button is the only control, the back or underside of the handpiece is free of buttons or controls.
On one side is the cover/access to the battery compartment.
At the top of the handpiece is a small rounded plastic nodule that the mouthpiece attaches to.
To attach the mouthpiece you align this plastic nodule with a similar sized hole on the bottom of the mouthpiece. Holding the mouthpiece at 90 degrees to the handpiece, you twist it into place.
It fits on quite securely and actually, it all felt quite robust. Much better than other similar products I have handled.
Powered by a single AAA battery, which is provided, I looked to get this installed into the handpiece. It’s here that the weaknesses really started to show.
You have the + or x style cutout on the cover to the slot for the battery, into which you might use a coin or a screwdriver to open it. I struggled with both.
A coin seemed more appropriate based on the width and depth of the groove, but as I tried to turn it to unlock the coin became loose as the plastic degraded/chipped away.
I was being gentle, but the plastic seems brittle here and I eventually managed to succeed with a very large headed screwdriver.
As the images show, this part of the product is essentially damaged now and I fear repeated use to replace the battery will result in more damage and eventually it will be impossible to open and close.
Before talking about my usage experience, let me explain the mouthpiece a little more.
Those different sized mouthpieces are for children and not adults.
Other mouth brushes today have been designed for adults only.
You see, uFunbrush has been designed primarily for kids rather than adults. Hence the 20 stickers that can be attached to the handpiece.
A quick word on the stickers. You get 20 of varying design. They are simple to apply to the handpiece and relatively easy to remove. Once removed they cannot be reused. It is a nice touch and makes the brushing experience a bit more fun for kids.
When in the mouth, if they were to look at themselves in the mirror, their mouth is essentially replaced with this sticker. The designs have anything from a nice set of teeth to an emoji-style mouth.
Whilst adults do have different sized mouths, the size of a child’s mouth varies considerably more based on their age. The different mouthpieces are designed to offer a solution for children of all ages.
The 4 mouthpiece sizes and the ages they suit are as follows:
- U1 -- 3-5 years
- U2 -- 6-8 years
- U3 -- 9-13 years
- U4 -- 14 years +
Given that this is the only kids oriented product of this type, it is a nice unique feature.
Getting kids to brush their teeth can be difficult, many parents (myself included) will likely tell you this. So if a product like this can improve habit and how well a child cleans their teeth then great.
By the age of around 14, the development of the mouth has slowed and is essentially adult sized.
Before letting any child use this, I wanted to test it myself, hence ordering the largest mouthpiece on offer.
Made from food-grade silicone, it is considered safe for use in the mouth and as hygienic as it can be.
It has a U shape design to it, with bristles on either side.
Your teeth essentially sit inside the U of the mouthpiece and the 5 rows of bristles clean the plaque away.
There are 3 rows of bristles which focus on the front surfaces of the teeth primarily with the other 2 getting the back of the teeth.
If you see some of the images throughout, you will see it fits the mouth fairly well and does sort of reach the gumline. However, the fit is far from ideal. You can see it does not reach the rear teeth on the model and the bristle contact with the gumline is not as good as it should be.
I have what I would consider to be a fairly regular sized mouth and tooth arrangement, but I could tell that in the mouth, the mouthpiece was nowhere near the correct size for me, falling short of my 2nd and third molars
Given that there is only one size of mouthpiece for adults, you may already be realizing how this might be an issue.
Although the fitment to the handpiece is strong and appears fairly robust, the mouthpiece itself is very flexible. It needs to be to adapt to the teeth and mouth, but it feels a little too flexible and I would like a bit more rigidity I think.
That said, the flex stops it feeling too awkward in the mouth, as was the case with Amabrush.
It is molded in such a way that despite being flexible, it springs back to its original shape instantly.
The smaller mouthpieces for children have the same design. I have only the U1 to compare the larger U4 to. The U1 does have 1 less row of bristles, because of the overall size of teeth it will be cleaning.
Given the less than ideal fit to my adult mouth, I was not confident with a child. As will become clear very shortly, I didn’t attempt to test this on any youngster.
It is suggested, like a regular toothbrush that the mouthpiece should be replaced every 3 months, which is unusual for silicone based products, as often the recommendation is 6-12 months. I guess uFunbrush are erring on the side of caution, which I can’t fault.
The single power button on the handpiece appears to be made from silicone and has a power icon debossed into it.
It actually provides a nice clicking sensation upon being pressed. It gives satisfying feedback and is neither very soft or very firm, meaning most would get along with using it to turn it on or off.
Mouthpiece style toothbrushes like this have been said to need different kinds of toothpaste.
Amabrush came with its own built-in toothpaste module to help deliver the right amount of paste in the right way to the teeth. uFunbrush supply in their kit a foaming paste.
It comes in a can and can best be described a little like applying shaving foam into the mouthpiece.
It is much more bubbly and lighter than shaving foam, but you probably know what I mean.
You get 1.76 oz (50g) in each bottle. How long this will last I am not entirely sure as I didn’t use uFunbrush for long enough to find out. However, based on needing to place 4 blobs of it into the brush head each time, I don’t think it would last that long.
I am not going to focus on this paste in this review, but it does not contain fluoride, which many dentists recommend. It contains xylitol and has a strawberry flavor, which is a nice alternative to mint.
I suspect the strawberry is so it is more appealing to the target market of kids.
What makes these mouthpiece toothbrushes appealing is the fact they can, in theory, spend more time brushing each surface of the tooth, despite the total brushing time being significantly less.
To understand the maths of how you can only brush for 10 seconds, but spend longer per tooth surface, refer to our article that explains this in detail.
uFunbrush has only 1 cleaning mode that lasts 10 seconds. You press the power button once to turn it on and activate the mode. Once the 10 seconds have passed, the brush automatically turns itself off.
You can turn the brush off sooner by pressing the power button again.
To ensure I got the maximum results from it, I took a detailed look at the small and basic instruction manual to ensure I was educated on how to use this.
Some manufacturers suggest different approaches, so I wanted to be sure.
Here is what uFunbrush state:
- Apply the foaming toothpaste from the bottle to evenly fill the corners of the brush head both top and bottom.
- Place the brush head in your mouth. Twist uFunbrush back and forth 6-8 times.
- Push the button and have some fun!
- For an even better clean, twist the uFunbrush back and forth during the brushing time.
The instructions then state:
Minimum brushing time: 10 seconds after pushing button. In general, 10 seconds will be enough to clean your teeth properly. Naturally, you can brush longer if you need.
So, to get the best results you need to move the brush side to side as it operates.
I followed these instructions to the letter and repeated multiple times, but to put it bluntly, the cleaning experience is terrible.
At no point during use or after did my teeth feel clean.
In fact, I think I could achieve a better clean in 10 seconds with a bit of toothpaste on my finger and use my fingertip as the brush.
To prove this point, I went 24 hours without brushing my teeth. I then used a plaque disclosing tablet to highlight the plaque in my mouth.
The image below shows my teeth before and after using uFunbrush for a single ten second cleaning session.
Any good toothbrush/toothbrushing technique will have gotten rid of the vast majority or ideally all of this purple/blue/red dye on the teeth.
The remaining dye, clearly shows that there is still a lot of plaque left.
To be fair, it is better than I had anticipated. But, I think my movement of the mouthpiece did the majority of what cleaning occurred in those 10 seconds.
The next image shows my teeth after a further 30 seconds of brushing (40 in total) and me trying to move the mouthpiece in any way possible to achieve a good clean.
This is quite a bit better and my teeth are quite a bit cleaner after 40 seconds. But you don’t need to be a dental professional to see that there is still a lot of plaque left.
If you used uFunbrush with these results day in day out, you would have a fast track ticket to bleeding gums, gum disease and possible tooth loss.
But, cutting some slack, the results were definitely better after 40 seconds of use than the results from other similar products I have tested to date.
When turned on, there is a mild vibration in the handpiece which can be felt on the front teeth only when in the mouth
Out of the mouth, you can see the bristles moving a little bit, but this is more pronounced at the front rather than the back and it is a LONG way from the Sonicare and Oral-B alternatives.
There is just not enough bristle movement to sweep away or disturb the plaque properly.
Couple this with the poor fitment of the mouthpiece to the teeth and gums and this just is not a viable solution.
What I can say, is that the cleaning experience was comparable, or perhaps marginally better than other mouthpiece toothbrushes I have used so far, so at least it achieved something?!
As you can probably tell, with such poor results for my teeth, I was not going to subject any child to this, they deserve better.
After a few days of testing, I chose to return to my own electric toothbrush, I was not prepared to risk my own oral health any longer and I advise you do not risk the health of your or your children’s teeth with this either.
Aside from the appropriate sized mouthpieces and stickers, there isn’t much else for kids here. Ok, if it worked in 10 seconds, would they need much more? But, I can’t help but think a small educational book, toothbrushing chart or similar would help encourage kids to want to brush.
Although the mouthpiece should be rinsed after use, you don’t want to use the toothbrush in the shower or bath. It is not waterprooof.
Not that you are likely to travel with this, but no travel case or solution is provided, it would have to go in a washbag or similar.
There is no mention of the warranty in the manual. It does provide an email address to contact, [email protected], which is the same email used for order inquiries.
So, if it is not clear, although the concept is great, stick with a regular manual or electric toothbrush, uFunbrush is not the answer to quicker and more effective brushing at this time.
Summary of design, usability, clean & general use
- 2 core pieces, handpiece and mouthpiece
- Different sized mouthpieces for different aged children and adults
- A single power button that provides good feedback
- Powered by a single AAA battery
- Quality of the plastics is questionable
- 1 cleaning mode that lasts 10 seconds
- Turns off automatically at the end of the clean
- Special foaming toothpaste required
- Does not clean the teeth very well at all
A single AAA battery powers this toothbrush.
1 does come provided in the box.
Removable batteries like this can be very convenient as they are easy to source and can make a product more travel friendly.
Some will prefer a built-in rechargeable battery, but there is no such option here.
Given than the cleaning time is just 10 seconds the battery should, in theory, last a lot longer than a regular electric toothbrush that might be powered by an AAA battery.
Quip is powered by a single AAA battery and lasts about 3 months or a total time of approximately 360 minutes.
According to uFunbrush the battery should last 600 brushing sessions. Or that would be a total running time of 100 minutes.
Based on two 10 second brushing sessions a day that is nearly a years battery life! Impressive, if only it cleaned the teeth well.
Needless to say, I was not going to get anywhere close to testing the life of the battery. I would imagine I would be having treatment to resolve the gum disease caused by its poor brushing before it ran out.
If you did need to replace the battery you need to be careful of the delicate plastic that breaks as you try to open the battery door.
Coins or screwdrivers struggle to get grip/traction on the +/x cutout on the battery door causing irreversible damage.
Summary of battery life
- Powered by a single AAA battery
- 1 battery supplied
- Lasts up to 600 brushing sessions, in theory
- Equates to nearly a years use between battery changes
- The battery door is susceptible to damage
Price & where to buy
I have included links to buying options here at the start of the review.
In the section below, I discuss the price more generally and in relation to similar products.
The suggested retail price of uFunbrush is $99.
Many early backers on Kickstarter and later Indiegogo were able to secure a much lower price for investing in the idea. Many paid around $49.
When I purchased this in May 2019, I paid the full retail price of $99.
However, since then the selling price has dropped down again to $49, but the RRP is still listed as $99.
Compared to other mouthpiece style brushes this could be considered quite good value at $49.
If it worked, this would be very comparably priced to a good conventional electric toothbrush.
However, based on the comments earlier in the review, I don’t suggest you spend a single $1 on this product at this time.
As is necessary with any toothbrush product, you need to replace the brush head/bristles.
There are a few ways you can do this with uFunbrush. You can subscribe for $19 or you can make a one time purchase of a refill kit (mouthpiece and foaming toothpaste) for $29.
The toothpaste on its own is $10 for a single tube and $24 for 3.
You are probably thinking this is a little more expensive than conventional options, and you would be right.
But, you won’t be buying replacement parts, because you would be risking your oral health if you continued to use this.
The only place you can buy the brush and the replacement parts are direct from uFunbrush. They not sold anywhere else.
There are some other sellers starting to offer a similar foaming toothpaste, but not made by uFunbrush.
Typically, to try and calculate the cost of ownership, we price a brush over a 3 year period.
Assuming you are able to buy for $49, you will then need a further 11 mouthpieces and toothpaste which costs $19 a time if subscribed.
This makes the total cost $258 or 24 cents per day.
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
- Retail price of $99
- Sells from about $49
- Mouthpiece and toothpaste $29 or $19 on 3 month subscription
- Works out at $258 or 24 cents per day based on 3 years ownership
- Replacement parts available from uFunbrush directly
Reliability & long term use
I can’t speak in all that much detail about reliability.
I have not used this product for long enough to be able to say whether this will stand the test of time.
I have made clear how poor the brushing experience is.
I have explained how the battery door has essentially begun to break down as I tried to open and close it, because of a lack of thread for a coin or screwdriver to catch on.
The design of the mouthpiece fitment is not absolutely terrible. The overall unit it’s nice and solid and would appear like it could last a long time.
There is however a distinct lack of support information in the manual and on the uFunbrush website.
Going by al the complaints on Kickstarter and Indiegogo about the product, I have serious concerns if uFunbrush would even respond to any communication about a faulty, let alone replacing or repairing it.
Like other mouthpiece style toothbrushes I have tried, this falls a VERY LONG way away from being a useful functional product.
DO NOT buy this to clean the teeth of you or your children.
Conceptually the idea is brilliant, but the execution leaves a great deal to be desired.
Don’t expect to see dental healthcare giants like Oral-B, Sonicare or Colgate to disappear from the shop shelves any time soon.
