Best Mouthwash Tablets, Powder & Concentrate

Best mouthwash tablets

If you want fresh breath, one of the things you might use to achieve this is mouthwash.

When you think of mouthwash, I suspect you visualise a large bottle of bright coloured liquid (usually green/blue or pink) that has a very strong (often too strong) flavour to it when you use it.

You might also be thinking that you never have the mouthwash when you really need it and instead opt for some chewing gum or mints?

Well, what if I said you can do away with the large bottle of mouth rinse and instead have a small tablet that would do the same thing?!

Imagine taking mouthwash with you, everywhere you go.

Now you can, thanks to a newer type of mouthwash product.

Say hello to mouthwash tablets.

These offer an alternative option to regular mouthwash. They can be more convenient, and in some cases, although they are not truly ‘zero-waste mouthwash’, they produce less waste (in theory at least) than regular mouthwash offerings.

Our Top 7 Choices for Mouthwash Tablets

In the sections below you can read a little more about each product and the reason we have chosen it.

Best Mouthwash Tablets, Powder & Concentrate 8

Mini Review

These Go! Tabs are a very convenient option for those that want a quick freshen up of their mouth and breath when on the go.

Made by Johnson and Johnson, the parent company of mouthwash brand Listerine, all you need to do is pop a single tablet in the mouth, chew it for 10 seconds, swish it around the mouth for 30 seconds and then swallow.

The tablets come in a mix of cardboard and plastic packaging. You can tear off the upper and lower part of the cardboard packaging, to make them smaller and more convenient to transport.

The result is a pack of tablets about a third taller and longer than a credit card.

Each tablet has to be popped out of the plastic/foil packaging like you would paracetamol or aspirin.

Best Mouthwash Tablets, Powder & Concentrate 9

The design of the packaging is such that it has a fold out how-to-use part on the front, so you always have these instructions to hand, a neat touch.

The chewable tablets are designed to give a whole mouth clean and fresh feeling on the go. At the time of writing, they are available only in a flavour known as clean mint.

As soon as you pop a tablet out, you can smell the mint flavouring.

Each tablet is square with rounded corners. There is an L debossed on each side.

The tablet is all white on one side and a mottled blue and white on the other. There is a clear line around the edge of the tablet where the two colours meet. It seems like the blue and white part of the tablet makes up about 60% of the whole tablet.

When handled there is a very light dust residue that is left on the fingertips.

Best Mouthwash Tablets, Powder & Concentrate 10

You do need to give the tablet a good few bites when you use it. It begins to break down, but without a few good chews, you will have a few larger pieces in the mouth still.

It does not go lumpy or powdery as you might think.

It offers a massive minty burst.

I like mint, but even for me, this was pretty strong.

The best thing I can compare it to is biting into a very strong mint, you are hit by a wave of mint. It was enough that when I breathed in, that flavour and freshness ran through the nose also.

That minty taste and sensation lasted for a good minute or so for me until it died down a little, into a more pleasant and desired freshness.

The tablets come in packs of 8 or 16.

It appears, at the time of writing the 8 pack is most widely sold.

The typical price appears to be around £3.50 for a pack of 8 and £5 for a pack of 16, although both have been subject to promotional pricing from a number of retailers.

As an approximate guide, a single tablet costs 43p when bought as a pack of 8 or 31p when bought in a pack of 16.

I have been able to find online sellers selling multiple packs of 8 or 16, packaged together as an offer of 48 tablets in total. This price was around £10.50 bringing each Go Tab down to just 22p.

At the time of review, the tablets had an expiry date of September 2021, meaning they should last a good couple of years from the time of purchase.

What we like

  • Convenience – chew, rinse, swallow
  • Different pack sizes
  • Pocket friendly
  • Availability – Widely stocked
  • Long shelf life

What we dislike

  • Cost – A premium for convenience
  • Taste – Can be overpowering for some

As the name somewhat implies, these are a super convenient option for refreshing the breath on the go.

Simply tear open the sachet, pour the powder onto the tongue, rinse around the mouth for 10 seconds and then swallow.

Keep a sachet or two in your pocket, bag, car, or wherever you choose, they take up very little space.

2g of powder is provided in a sachet.

The process feels a little like a nod to sherbet straw sweets, if you are familiar with them.

You get the powder texture, which is not at all unpleasant and within a few seconds you get a really foamy solution in the mouth that you swish around.

I have used the fresh mint flavour, but cool mint and zesty lemon options are available.

I found you get a big hit of flavour, almost too much, but it soon dies down to a much more desirable and less intense taste.

Best Mouthwash Tablets, Powder & Concentrate 12

That freshness lasted for a reasonable amount of time, but it is hard to say how long it lasts, much depends on your diet etc once you have used a sachet of swish to go.

It can feel a bit odd to swallow the foamy solution, but it is designed to be swallowed, so you don’t have to find a convenient place to spit it out.

You can buy them in packs of 20, which at £10 a pack makes each sachet worth 50p on average. It is not the cheapest, but certainly a convenient option.

The sachets are a plastic/foil material which I don’t believe is recyclable and considering the amount of powder, the sachets are almost twice as large as they need to be but sized to be practical to handle.

A point to note is that there was not clear shelf life shown on the product. Nothing on the outer box or each sachet to say when it should be used by. I imagine it has a fairly long shelf life, but I suspect there comes a point where it goes off, if there is, I can’t say when this is.

What we like

What we dislike

  • Pack size – Larger packs with more sachets would be useful

3. Lush Mouthwash Tabs

Best Mouthwash Tablets, Powder & Concentrate 14

Mini Review

Suitable for vegans, these mouthwash tablets are made by world renowned cosmetics brand Lush who are all about natural, cruelty-free products.

Available in 3 different flavours, Brave, Pan Galactic Gargle Blaster and Creme De Menthe, you get a 45g plastic bottle (made from recycled plastic) that contains approximately 80 tablets.

You have a screw top to the bottle to access the tablets.

Each tablet is a diamond shape and these more than others I have tested are most likely to leave a dusty trail on the hand/fingertips.

Best Mouthwash Tablets, Powder & Concentrate 15

Unlike Swish to go or Listerine Go Tabs, you place a single tablet in the mouth and take a little sip of water. The tablet begins to fizz, but you can chew it slightly to help break it down. You then rinse it around the mouth and then spit it out.

You do not swallow this solution.

I have used only the Creme De Menthe, which give a peppermint freshness.

Once popped into the mouth, with a few chews, the tablet breaks down. A sip of water certainly helps it turn into an oral rinse.

Of all the mouthwash tablets and powders I have tried, this has what I describe as the more gritty taste. The tablet had broken down, but there was just a rougher texture to the solution than others.

The solution was more mouthwash like and less foamy than the Listerine Go Tabs of Swish To Go.

A really refreshing burst of freshness was produced. Verging on intense, it quickly became more subtle and appeared to last for a reasonable amount of time.

Best Mouthwash Tablets, Powder & Concentrate 16

There is just the one pack size that will normally cost around £6.50.

With 80 tablets in the bottle, this is generally going to last around 2.5 months on average and cost just 8p per tablet.

The tablets appear to have a shelf life of about 14 months.

On each bottle is a sticker showing the date made and the use by date.

At the moment Lush does not offer the option to buy its Mouthwash Tabs without packaging. However the plastic bottles that they come in are made from recycled plastic and can be put in your home recycling.

What we like

  • Good pack size
  • Refreshing taste
  • Suitable for vegans
  • Recyclable packaging

What we dislike

  • Not the most widely stocked
  • More gritty texture

Mini Review

Made in England, these tablets can be purchased in either Spearmint of Wild Thyme flavours.

The tablets take on a green or pink coloured respectively.

Supplied in a glass jar, you can purchase 180 or 720 tablets at a time.

You screw off the silver plastic lid to access the tablets inside.

The tablets have a 12 month shelf life once opened.

The idea with Georganics tablets is that you place an individual tablet into approximately 20ml of water so that the tablet breaks down and dissolves.

You then place this mixture into the mouth, gargle it for 30 seconds and then spit it out.

Best Mouthwash Tablets, Powder & Concentrate 18

I have used the Spearmint tablets and as you open the jar, you are not hit with quite the same intense minty hit as you are with some other products, but it is still a fairly strong fresh smell, although there is a more natural smell to them.

The tablets are smaller than the Listerine Go Tabs or Lush Mouthwash tablets and leave little of a powder trail when handled.

Once in the water, they take a little while to dissolve and I encouraged the tablets to dissolve by using a spoon to crush them and stir into the water.

The resulting liquid is quite an intense green colour, more akin to regular mouthwash.

Sadly, I was not a fan of the smell by the time the solution was ready to go, it was not all that appealing to the nose.

The taste was also a little more unusual, not as intense or sweet as others. It is harder to describe, but much earthier and I think the worst tasting, in my personal opinion, of all the products I have tried. The taste is certainly going to be a bit hit or miss for some.

Best Mouthwash Tablets, Powder & Concentrate 19

In terms of lasting freshness, it was disappointing in comparison to the others also, it was much more subtle overall.

Compared to the very convenient options where you can simply place the tablet in the mouth, chew, rinse and swallow this is the least convenient, but typically works out to be one of the most cost-effective options.

20ml of water you need to dissolve the tablet in is approximately the same amount of liquid you would use if you were using a pre-mixed liquid mouthwash like Listerine.

180 tablets, will generally last about 6 months, if you use just 1 tablet a day.

Priced at £8.90, a single tablet works out at 5p.

Opt for the 720 tablets (ideal for couples or families) and the cost drops to just 2p per tablet.

Mini Review

Made in England, by Halewood Health, this box contains 30 tablets mouthwash tablets, that have a fresh mint flavour.

The cardboard box contains 2 trays of 15 tablets each.

Although each tablet is green in colour, the packaging makes it look like this is some sort of prescribed medication, rather than a mouthwash tablet.

Each tablet needs to be popped out of the foil tray, which I don’t believe is recyclable.

Best Mouthwash Tablets, Powder & Concentrate 22

To use, you need to place 1-2 tablets into about half a glass of water.

You then need to give it a few seconds to allow the tablet to dissolve fully.

Once dissolved, you can then rinse it around the mouth and spit out when you are done.

You cannot swallow this mouthwash.

Alcohol-free, the product is supposed to target bad breath.

The claimed benefits are the feeling of ultimate clean teeth, being a convenient way to freshen your mouth and breath as well as having a great refreshing taste.

The experience of using these was similar to Georganics in that the tablet was a little slow to dissolve and really needed a bit of encouragement.

Best Mouthwash Tablets, Powder & Concentrate 23

Using half a glass of water, got you more oral rinse, but left the solution much more watery in taste and less refreshing. You really do need 2 tablets if you use half a glass of water. Use 20ml of water and you can use just 1 tablet and get a more effective cleanse in my mind.

However, if you don’t like the intensity of regular mouthwash things could be good.

Whilst the freshness lasted a while I can’t say I noticed the freshness remain for as long as I would have liked.

I paid around £6 for this pack, making each tablet 20p.

This is quite high in my opinion, and similar to the price of the most convenient mouthwash tablets and powders offered by Listerine and Swish to go. Considering you need to mix with water and spit out, I am not sure what justifies this higher cost.

Making this product an even more expensive option is the suggestion on the directions to use 1-2 tablets. I think just 1 tablet each time is enough. It could get relatively expensive if you used 2 each time.

Best Mouthwash Tablets, Powder & Concentrate 24

Rather impressive is the shelf life of these tablets. My pack expires in 2022, that is well over 3 years from the date of purchase.

What we like

  • Long shelf life
  • More subtle flavour

What we dislike

  • Price
  • The least convenient mouthwash tablets to use
  • Not widely stocked

28 tablets come supplied in a plastic tube, which is packaged in a small outer cardboard box.

The tube itself is reminiscent of a test tube and is shorter than the average pen, but not quite as thick as a marker pen.

Although I don’t believe the tube is recyclable it is certainly conveniently shaped for storage in a pocket, bag etc. It is easy to take these tablets with you.

It would be nice to see other companies use a similar tubular design for their tablets.

Pull off the cap and take out 2 tablets each time you want to use.

You need to place the tablets into a small glass of warm water. You need to then give them time to dissolve.

Once dissolved, the mouthwash solution can be rinsed around the mouth for 30 seconds and then spat out.

The solution should not be swallowed.

Best Mouthwash Tablets, Powder & Concentrate 26

When placed in warm water the tablets soon begin dissolving and fizz, much like a vitamin tablet might. The tablets dissolve better in warm water than cold and require less encouragement to break down than other brands do.

The result is quite a vivid green rinse.

The taste was not the best, it wasn’t quite the minty fresh hit I like. There was a freshness, but far from as intense and in my opinion, the freshness didn’t last quite as long either.

It is said to target dry mouth. The ingredient Sodium Benzoate helps with this. I do not suffer with this condition myself to be able to comment on how hydrating and useful it really is.

However, even if it does work, this feels like a relatively expensive option.

I bought a pack of these for £6.

With 28 tablets included that is 21p per tablet. However, it is suggested that 2 tablets are used each time which makes the price over 40p per use.

Given that you need to have a glass of warm water and spit this solution out it becomes a much more expensive option, given the lack of convenience. That said, if it works for dry mouth sufferers, it could be a small price to pay.

Best Mouthwash Tablets, Powder & Concentrate 27

Those with dry mouth tend to want to refresh their mouth more frequently, so you would likely get through these tablets even sooner.

At just 1 use a day, the 28 tablets would be gone in 14 days.

A dry mouth user might use all of these in well under a week.

A sticker on the box and tube of tablets confirms the expiry date, which in this instance is August 2020. That is at least 18 months later than the date of purchase, so it is good to see a reasonable shelf life.

What we like

  • Packaging design
  • Quick to dissolve
  • More subtle flavour

What we dislike

  • Price
  • The least convenient mouthwash tablets to use
  • Not widely stocked
  • Will use tablets up quickly

German-made One Drop Only is a liquid concentrate mouthwash.

Packaged in a cardboard box, inside you find a glass bottle.

There are 10, 25 and 50ml options. I have the larger 50ml.

On first glance, it looks like a bottle of aftershave or eau de toilette. The slightly loud label and red cap makes it clear the packaging is not quite as refined as you might get from a cosmetics company.

The idea is that you place a drop of the concentrate into 15ml of water.

Best Mouthwash Tablets, Powder & Concentrate 29

The concentrate mixes with the water to create a less intense and more useful solution that you then rinse around the mouth and spit out, like a regular mouthwash.

You are not meant to swallow this mouthwash.

The convenience here is the smaller pack, compared to a normal oral rinse. You add the water yourself rather than buying the rinse pre-mixed.
To use it, you unscrew the red cap and tip the concentrate into a 15ml glass of water you have ready.

You unscrew the red lid and are hit with the concentrated smell of peppermint.

Initially, I thought it would be hard to control the flow of concentrate out, I thought I would pour too much. However, the design is such that only 1 or 2 drops do come out, without a bit of shaking of the bottle.

This concentrate should last you at least 1-2 months. Although likely less if you were to use it the suggested 3 times a day.

When mixed with water this really gives the taste and experience much like a regular mouthwash.

There is a definite intensity to the flavour and cleansing sensation although the liquid is clear like water, no intense colours.

Alcohol does form part of the mix and you can taste this. Seeing as many don’t like the harshness of alcohol in mouthwash some people will want to avoid this.

The freshness did last.

Best Mouthwash Tablets, Powder & Concentrate 30

With one of the largest ingredient lists of such products, this concentrate is more akin to traditional mouthwash than tablets or powder really.

At around £10 for this 50ml bottle, I think this is fairly competitively priced and is similar to regular mouthwash prices.

Once opened, it should be used within 12 months.

What we like

  • Strong concentration
  • Glass bottle
  • Bottle design allows only a couple of drops at a time
  • Lasting freshness

What we dislike

  • Alcohol will not be for everyone
  • Longer list of ingredients
  • Not the most convenient option

Buyer’s Guide

Let me explain all there is to know about the mouthwash, now in the form of a tablet.

By reading, you can learn how they compare to traditional mouthwash liquid (which we have covered thoroughly in our best mouthwash article) and why you might want to make the switch.

What are mouthwash tablets?

Mouthwash tablets are a solid alternative to regular mouthwash, which is usually supplied as a liquid.

The tablets are normally a compressed powder, that becomes a liquid upon being placed into the mouth or mixed with water.

Typically small round tablets, they are shaped similar to tablets you might get if buying aspirin or paracetamol.

There are also mouthwash products that come as a powder or a liquid concentrate.

Tablet, powder or concentrate, they achieve the same results as a regular mouthwash but are supplied in what many would consider a more convenient form factor.

Best Mouthwash Tablets, Powder & Concentrate 31

Other names for mouthwash tablets?

Mouthwash tablets are the most popular and commonly used name for this type of product. However, there are some other names they are known by:

  • Mouthwash tabs
  • Mouthwash powder
  • Mouthwash concentrate
  • Go Tabs
  • Chewable mouthwash
  • Zero waste mouthwash
  • Eco mouthwash
  • Solid mouthwash

Whilst the majority are in a tablet form, some do come as a powder or a concentrate.

Best Mouthwash Tablets, Powder & Concentrate 32

What do mouthwash powders and tablets replace?

The tablets, powder and concentrates are designed to be an alternative to these bottles of mouthwash that most of us are familiar with.

Bottles of mouthwash are primarily water, which adds to the overall size and weight of the product.

Doing away with the water, the tablets are a smaller, lighter and a more environmentally friendly approach.

Best Mouthwash Tablets, Powder & Concentrate 33

How are mouthwash tablets better for the environment?

These tablets, powders and concentrates leave a smaller carbon/environmental footprint.

This is achieved in a couple of ways.

The first way is through generally requiring less raw materials to create the packaging.

Because they do not contain liquid (water) the volume of the product is less and the packaging requirements are not as great.

The second and perhaps the largest impact is the implications of shipping these smaller and lighter products.

Whilst this is not a scientific answer, some basic calculations show just how significant a difference there is between tablets and liquid mouthwash.

Best Mouthwash Tablets, Powder & Concentrate 34

Take a 1 litre bottle of Listerine mouthwash. This weighs approx 1kg (1000g) and will last approximately 20 days if you follow their usage guidelines.

Compare this to a bottle of mouthwash tabs from Lush cosmetics that weighs in at 45g, and in fact, give 40 days of use, not 20.

Each bottle of mouthwash tablets is a staggering 955g lighter.

When you consider the additional size and weight of the Listerine bottle and the millions that are sold each year, you do not need to be a genius to work out that using a liquid mouthwash takes up a lot more space in lorries and it requires a lot more fuel/natural resources to transport all of these.

It also takes up more space on the shop shelves, in your shopping bags etc.

That 1kg bottle of Listerine mouthwash is the equivalent weight of 22 packs of mouthwash tablets.

22 packs of mouthwash tablets could last you 880 days or 2.4 years.

That’s pretty incredible right.

Best Mouthwash Tablets, Powder & Concentrate 35

Well, now let’s assume you stuck to Listerine for the same 880 days. You would need 44 bottles of Listerine. That is 44kg in weight, 43kg heavier than the tablets.

I don’t know precisely how many people in the UK use mouthwash on a daily basis. The best data I could find was from a 2011 study restricted to the Grampian region of Scotland.

The study found that 25% of respondents used mouthwash daily.

This is just a bit of loose theory, but let’s assume 25% of the 66 million people in the UK use mouthwash daily, that is 16.5 million people.

Now, let’s assume that all 16.5 million switch to mouthwash tablets.

If we took the earlier stats of 1kg of mouthwash tablets being equivalent to 44kg of Listerine, that is potentially a 43kg saving per person (over 880 days, 17.9kg per year).

Multiply the 43kg saving by 16.5 million and you have a total weight saving of 709,500,000kg.

The average lorry in the UK carries 44 tonnes. Not having to move 709,000 tonnes of mouthwash around the country could mean over 16,000 fewer lorry journeys, which will mean less CO2 being emitted. That is a sizeable potential impact to be had.

The maths might not be perfect, but you get the idea.

Best Mouthwash Tablets, Powder & Concentrate 36

Benefits of mouthwash tablets

The positives of mouthwash tablets are:

  • Convenience – The small tablets are easier to carry and move around rather than the larger bottles of mouthwash. You can use as and when you please with a little more ease. Some can even be swallowed.
  • Eco-friendly/packaging – When offered in a tablet, powder or concentrate form less packaging is required, because the item is smaller as the largest volume item, water, is removed from the equation. It also means less weight to transport.
  • Zero waste options – Whilst there are few brands that are offering completely zero waste options for mouthwash the tablets allows this to be achieved or at least closer to it than the regular mouthwash products.
  • cost-effective – They are actually more cost-effective than many bottles of mouthwash.

Negatives of mouthwash tablets

The drawbacks to mouthwash tablets are:

  • Availability – Although improving, there are fewer companies and brands offering mouthwash tablets and these are not widely stocked. You often have to shop online or visit a particular outlet to find them.
  • Variety – There isn’t the variety of flavours in the tablet form as there is the liquid.
  • Specialist options – There isn’t currently the specialist options you have available with liquid mouthwashes. No mouthwash tablets available today (as far as I know) include fluoride and limited options that are designed to specifically target conditions such as gum disease or dry mouth.
Best Mouthwash Tablets, Powder & Concentrate 37

Are they better than regular oral rinse?

The answer to this question is ultimately personal opinion.

For the average individual, the tablet or powder mouthwash does the same job as the liquid option.

The tablets provide a refreshing and fresh breath sensation we desire.

In many cases, it is more convenient, because you can take the mouthwash powder or tablet with you on the go.

However, as some tablets require water, this might not be quite as simple to use in comparison to the bottles of oral rinse that contain it in a liquid form already.

From my own use, I am not able to say that a bottle of mouthwash was any better in offering that freshness than a tablet.

That said, some options were a bit more natural tasting with not quite as pleasant taste during and after use. It may be a case of finding the ones best suited to yourself.

For those who have been advised to use a specialist oral rinse, then these tablets, at present are not better or a viable alternative.

Where I think all will agree they are better is the environmental impact that comes as a result of using them.

Best Mouthwash Tablets, Powder & Concentrate 38

When do you use them?

You should not use any mouthwash, tablets or liquid straight after you have brushed your teeth.

Rinsing having just brushed your teeth can undo all the good done by the brushing.

Rinsing with mouthwash should really be done at times when you do not have a toothbrush to hand and you want the refreshed feeling.

A common time people might make use of mouthwash is after lunch or after snacking mid morning or afternoon.

This then is why tablets are a great option, if you are away from home and want to refresh on the go.

Best Mouthwash Tablets, Powder & Concentrate 39

How do you use them?

How you use mouthwash powders or tablets does vary slightly.

From what I can tell there are 3 main approaches, listed below. However, always consult and follow the instructions/directions provided by the manufacturer, before using.

  • Chew, rinse and swallow (The most convenient)

This type of tablet allows you to place it in your mouth, chew it so it mixes with the saliva, rinse it around your mouth and then swallow it.

  • Chew, rinse and spit (The most common)

These products allow you to place the powder or tablet into the mouth, chew and mix with saliva or a small amount of tap water, rinse it around the mouth and then spit it out.

  • Mix, rinse and spit (The least convenient)

This type of powder or tablet is designed to be placed in a small amount of water, given time to dissolve (or be mixed). It is then placed into the mouth, rinsed around the mouth and spat out.

Best Mouthwash Tablets, Powder & Concentrate 40


All tablets and powders use a different variety of ingredients.

This will not apply in all cases, but as a general rule, the number of ingredients tends to be fewer in the tablet and powder options, compared to the pre-mixed liquids.

A large number of manufacturers use more natural ingredients whilst some still do use and rely upon man made ingredients and safe chemicals.

For the sake of example, the ingredients list for Lush Creme De Menthe Mouthwash tabs are as follows:

  • Dicalcium Phosphate Anhydrous
  • Sodium Bicarbonate
  • Silica
  • Citric Acid*
  • Sorbitol
  • Malic Acid
  • Glycerine*
  • Stevia*
  • Xylitol
  • Flavour*
  • Menthol Crystals*
  • Peppermint Oil*
  • Peppermint Powder*
  • Titanium Dioxide*
  • Synthetic Fluorphlogopite

Cost – Are they worth it?

Yes, they are.

Unlike many products that command a premium for being a bit more environmentally conscious, this is not the case here.

Using the Listerine and Lush products as an example again, a 1 litre bottle of mouthwash is around £3.50, whilst the tub of tablets costs about £6.50.

However, the bottle lasts 20 days, whereas the tablets last 40. 2 of the bottles will total £7, but you only need 1 tub of tablets, which are 50p cheaper.

Georganics mouthwash tablets cost approximately £9 and last 90 days, if you use it in an equivalent manner to Listerine. Over 90 days, you would need to buy 4 bottles of Listerine at over £15. That is a £6 saving by going with the tablets.

Yes, individual products and prices vary and in some instances, you need a small amount of tap water to use the mouthwash tablets, but all things considered, they are generally the more cost-effective option.

Where to buy mouthwash powder and tablets?

Depending on your location will depend on where you can buy these products from.

Most of us can buy the products online and have them shipped to us.

In some instances, it is possible to visit local retail stores and buy them off the shop shelf. We hope these opportunities increase.

We have included a variety of online buying options in the product-specific sections above.


There are a number of frequently asked questions about mouthwash tablets and powder. Here are the most common complete with answers.

What do they taste like?

It depends on the particular product you chose to buy, but most stick with the mint flavouring which is common amongst mouthwash and dental health products.

Are they messy?

No. Whilst some tablets are a touch dustier and leave a very slight powder residue, the majority are well compressed and leave no mess behind.

If crushed, they do leave a powder trail, that can easily be cleaned and likely do a little less damage than liquids if spilt.

Do they taste chalky or go lumpy when bitten?

The vast majority do not. I cannot comment on all brands of mouthwash tablets, but most quickly transform from a powder to a liquid, without the sticky, chalky and clumpy texture that can exist in some cases.

Can you swallow them?

It depends. The vast majority are not designed to be swallowed. However, particular products such as Listerine Go Tabs are designed to be swallowed like you might a mint or sweet.

Always check the packaging and instructions before doing so, it will usually make clear if safe to swallow.

Are they suitable for vegans?

Yes, they can be and the vast majority are.

It is however always worth double checking the ingredients or with the manufacturer.

How do I store my mouthwash tablets?

You always want to keep the tablets or powder out of contact with water as this causes the reaction and turns the product into mouthwash.

Some tablets come in packaging where they are sealed and that seal is broken each time you use a tablet, like a pack of paracetamol or aspirin.

Powders often come in small sachets (much like sugar sachets you may get at a coffee shop) that are designed to be thrown away once opened and the powder used.

The majority come in small plastic or glass jars with a lid to keep them fresh and out of contact with water.

If travelling or you want to take tablets with you, then popping into a small bag/container can be a convenient way to take them with you wherever you go.
