Editor’s Note: If you’re thinking of buying a charcoal toothpaste or powder, we recommend first checking out our best charcoal toothpaste article. It contains a huge guide on using and choosing charcoal toothpaste.
The Japanese are well-known in the west for being very innovative and creating excellent products. Admittedly this perceptions tends to apply more to technology products more than dental, but here we have a charcoal toothpaste from Japan.
Being imported into the UK via a marketplace seller on Amazon, this is an equivalent to many of the other charcoal based pastes that I have reviewed here at Electric Teeth.
Now I will admit my Japanese is lacking so I am a little limited on how much detail I can go into, but having tested it for 2 weeks I think I am in a good position to give my thoughts, feedback and opinions.
- Charcoal works to sources of the smell and plaque
- Beneficial to whiten teeth, remove surface plaque, smell, prevent cavaties, etc.
- Herb mint flavor
- non fluoride
Does it actually work?
Yes, it cleans the teeth and mouth well. I have however been unable to see and whitening benefits.
How much does it cost?
Considering this is an imported product the price is pretty reasonable at around at the time of writing at around £6.50 per tube.
Where can I buy it?
Within the UK, the only outlet through which this could be purchased is Amazon.
- Promotes the reduction of bad breath as well as teeth whitening
- Feels like it cleans well
- Ease of use
- Screw cap
- It’s all in Japanese
- Taste – not to my liking
- Unable to confirm if any better than a regular toothpaste
Would I recommend it?
Whilst it all appears to do a reasonable job of cleaning the teeth, my lack of Japanese and familiarity with the company behind this product leaves me a little uncomfortable in recommending it.
I believe there are others out there that are just as good, but all instructions are in English.
Charcoal toothpastes and products are of real interest at the moment and I have been conducting a great deal of research and investigation into it and what it can do for the teeth and the body.
There are thousands of people on Instagram, YouTube and in beauty and fashion blogs and printed media claiming how wonderful charcoal is as a whitening product for your teeth.
Whilst there is evidence from all of these different users that it can have some positive impact on the colour of your teeth, for the most part and for those with already pretty good healthcare, the differences are almost impossible to tell.
Charcoal has been used in medicines for many years, particularly in relation to poisonings, however there are suggestions that the use of it goes further back.
Now we are not talking about your average charcoal here, we are talking about ‘activated charcoal’ this is the type of charcoal safe for use in the mouth.
Whilst it is considered safe for use, there are many questions still over the long term safety and impact on your teeth. I have covered this in quite some detail here in our charcoal toothpaste guide.
The biggest concern is around activated charcoal in its natural form, as 100% powder and no additional ingredients.
However, where charcoal can really shine and why it is used by medical professionals for poisonings is its ability to absorb.
Essentially charcoal can absorb microscopic particles such as toxins, plaque and more and help remove them from the body.
It is this that really makes charcoal so appealing.
The idea is the charcoal bonds the bad bacteria and toxins together and these get removed as you brush and spit out the paste, in turn leaving the mouth fresh and the teeth cleaner.
How I tested Sumigaki Japanese Charcoal toothpaste
I tested this toothpaste in a similar fashion to all those I have tried before, at home under normal consumer conditions like you might.
This test has not been conducted in a lab with any fancy scientific equipment.
For 2 weeks, I used this paste morning and night, for 2 minutes, with my Oral-B Genius 9000 electric toothbrush.
Whilst the brush boasts a whitening modes, I used this on the conventional daily clean mode with a CrossAction brush head, as I believe this is more realistic of how you may use the product.
Not everyone has an electric toothbrush, those that do may not have a whitening mode either.
I made no changes to my brushing other than using the deep clean toothpaste.
I flossed once a day and made no other significant changes in my diet or habits. So teeth staining liquids like tea were still present.
Summary of how I tested the toothpaste
- Test lasted for 2 weeks
- Used Oral-B Genius 9000 electric toothbrush
- Cleaned twice a day for 3 minutes
- Flossed once a day
- No changes in diet
Having established how the charcoal works and what it really does in the mouth it is fair to say that many have been guided into believing that charcoal based products can do wonders when in all reality for the vast majority the results are not quite as promising as the images may suggest.
There is too much evidence to say that they do not work; but I and many others have struggled to see any significant impact. Please do not think that by using Sumigaki or any other charcoal paste or powder it is suddenly going to take your teeth to really shiny white nashers. However, some will see improvement, particularly if you have heavy staining.
After 2 weeks testing this paste, I have seen no noticeable colour change, but I can confirm that post use my teeth did feel clean.
Using the wonderful Google Translate, the Sumigaki toothpaste packaging does not really shout about being able to whiten teeth; it does acknowledge this, but actually focuses on the freshness of the breath and removal of odours from the mouth.
At the core this is what charcoal does well, removing the bad bacteria that can affect the health of our teeth and gums and the freshness of our breath.
This paste is certainly black in colour and has a very fine grit to it if you are specifically looking to taste the charcoal, but for the most part it is a fairly smooth paste.
Straight out of the tube it has an odd flavour. It is supposed to be mint, but it smelt and initially tasted a bit more like a bubblegum flavour. I then within a few seconds got the mint taste, but I have to say this for me has to be one of the worst tasting toothpastes I have ever used.
Whether I am the only one who thinks this, I am not sure, but I struggled to complete testing of this paste as I did not like the resulting taste and felt I had to really rinse my mouth out well post clean, something I would not normally do.
When cleaning the paste does go from a black colour to a very dull grey colour and does foam a bit, but not as much as Colgate’s Deep Clean Charcoal paste.
Using translate again I understand the ingredients of this paste to be:
Hydrophosphoric acid (cleaning agent), sorbitol, glycerin (wetting agent), silica (thickener), lauric acid Na (inclusion) cellulose Ethanol (solvent), 3 Mg (stabilizer) of phosphoric acid, lauroyl sarcosine Na (blowing agent (blowing agent) ), Ethylparaben / propylparaben (preservative), saccharin Na (sweetener).
The ingredient of charcoal does seem to be missing, but to be fair my ability to read the Japanese from the packaging. A bit of searching on the internet has failed to turn up a thorough list.
Unlike charcoal powders that are normally brushed onto the teeth for a couple of minutes, left for a couple of more and then rinsed off, you use this just like a normal toothpaste.
Whilst I can’t read the Japanese, the white packaging is smart with a screw cap — although I prefer a flip lid — that allows you to stand the tube upright on a countertop.
At around £6.50 for a 100g tube, the price is actually very good in my mind compared to the competition.
There is enough to last approximately 3 months.
I think I would rather pay a little more to get an English packaged product from a brand I am more familiar with, but still given the clean and fresh feeling (even if it was not to my taste) is pretty good.
Sadly I am unable to confirm if it is really any better at cleaning than a normal toothpaste — this is something I believe you will feel personally after weeks and weeks of use or if you notice a difference in your overall oral health.
Summary of Daily Usage
- Screw lid
- Tube stands upright
- Smart packaging
- Packaging in Japanese
- 100g tube should last about 3 month’s
- Pea sized amount of paste
- Black coloured paste
- Promises to reduce bad breath odours as well as help whiten the teeth
- Minty flavour, but with a distasteful aftertaste in my opinion
- Fairly good value
After use my mouth did feel clean, but the minty freshness was not to my taste.
After rinsing my mouth out it was a bit better.
It did work as a toothpaste, giving a clean feeling but I was unable to see any colour changes to my teeth, albeit this is not one of the primary selling features.
Reading other users reviews on Amazon would suggest that they have seen benefits. In fact some 70% have rated it favourably, all of which are reviews from verified purchases.
Conclusion, is Sumigaki Japanese Charcoal Toothpaste toothpaste any good?
I have been left with a bit of a bad taste from using this charcoal toothpaste, but I think that is just me more than it not necessarily being to everyone’s taste.
The lack of English language or rather my lack of Japanese has not endeared this product to me.
However, my teeth were clean post use — I experienced no side effects and in some respects it has done what it says it does.
My personal feeling and conclusion is that you can probably opt for something similar that will perform just as well but with added confidence that you can have from being able to read the packaging.
