Sodium Lauryl Sulfate (SLS) is a detergent. This means it has a foaming action. As an ingredient, it is added to lots of different things, from house cleaning products or shampoos to toothpaste.
There is some debate regarding the use of SLS in toothpaste, and some people prefer to avoid it.
In this post I therefore give some recommendations for the best SLS-free toothpastes, but also go into more detail about why it is included in some toothpaste products in the first place.
Why is SLS included in toothpaste?
Before you decide to exclude SLS from your toothpaste, it might be useful to know why SLS is in toothpaste.
SLS is included in toothpaste because of its cleaning action, and because it helps to stabilise other ingredients found in toothpaste (for example, helping the oil based and water based ingredients to stay mixed).
There are also some known benefits of adding SLS to toothpaste:
- SLS is antimicrobial – it can help kill bacteria.
- SLS can prevent formation of plaque (which causes cavities and gum disease).
- SLS causes foaming, which is cleansing in itself, helping to loosen debris on and around teeth.
- SLS and its foaming action helps to spread toothpaste into hard to reach areas, for example helping to get fluoride between the teeth where a toothbrush cannot reach.
- People generally like the foaming sensation of toothpaste containing SLS, and it does not leave an unpleasant aftertaste (unlike some alternative detergents that could be used).
Several of the recommendations in my more general best toothpaste article do include SLS.
Why choose a toothpaste without SLS?
Despite all these known benefits, there are some known risks (and some misinformation) about toothpastes containing SLS.
There is some evidence to show that SLS-free toothpastes are just as effective as toothpastes containing SLS despite the benefits listed above.
Why are people looking for a SLS-free toothpaste? Well, reasons to avoid SLS include possible health concerns, environmental concerns, and lifestyle choices aiming for a natural toothpaste.
Known health reasons to avoid SLS toothpaste include:
- Repeated use of products containing SLS can lead to dermatitis, although generally speaking this only applies if it is used in high doses and if it has prolonged contact (which isn’t always the case in the mouth, where saliva helps to wash the paste away).
- SLS causes irritation to the cells of the gums and soft tissues in the mouth. This can lead to mouth sores and stomatitis. Trials have shown SLS to cause uncomfortable mucosal sloughing (when the top layer of your gum falls away from the surface).
- Evidence shows that SLS can cause increased irritation to people who already suffer from recurrent aphthous stomatitis. Toothpastes containing SLS can slow down healing and increase pain if you suffer from regular ulcers in your mouth. The recommendation is that you avoid toothpastes containing SLS.
An unpleasant side effect after using a toothpaste containing SLS is that it may affect your taste buds after usage. You may have noticed this yourself, in what the authors of this paper described as the orange juice effect: “when consuming a citrus juice drink just after toothbrushing with an SLS dentifrice, SLS causes an astringent and unpleasant taste sensation.”
Finally, if you are Looking for a natural toothpaste, you may want to avoid SLS. It is possible for SLS to be made synthetically or can be derived from a natural source.
3 good options for toothpaste without SLS
These are by no means the only good toothpastes that come without SLS — there are plenty of options.
To keep things simple I have listed 3 good options immediately below, but I also include other options later on in the article and a list of SLS-free toothpastes at the bottom of the page.
Denttabs Toothpaste Tablets with Fluoride

I have picked these as one of the best toothpastes without SLS because they are also eco-friendly. Toothpaste tablets are the way to go when it comes to thinking about your impact on the environment. The bag they come in is compostable, so there really is zero waste here.
Denttabs contain fluoride for protection against cavities, and are free from SLS. Despite being SLS-free, they do foam a little during use which means they actually will help with the cleaning process.
Pros
- Free from preservatives and artificial stabilizers.
- Contains fluoride
- 100% plastic free packaging – more environmentally friendly.
- Travel friendly option as no liquid.
- Just the right amount each time (1 tablet = one dose).
- Low abrasivity – RDA 30.
- Vegan and cruelty free.
- Gluten free.
- SLS free.
- Some organic ingredients.
Cons
- More expensive than regular toothpaste.
- Not that easy to source, only available at select retailers.
- Initial taste can take getting used to.
Where to buy
Price comparison
- Packet of 125 (approx 2 month supply)
- Approx. $8 – 10 / packet

Sensodyne Pronamel Daily Protection

Sensodyne is one of the most widely available and affordable brands of toothpaste out there. What’s more, many of their products are SLS-free.
The Pronamel Daily Protection toothpaste has made it to the top of this list due to the additional benefit of protection against acids – a very common problem with a modern diet. This is also the best SLS-free toothpaste if you suffer from sensitivity.
Pros
- SLS-free.
- Widely available in shops.
- Contains fluoride
- Also helps relieve sensitivity.
- Protection against erosion from acids.
Cons
- Use of single use plastics
Best SLS-free toothpaste without fluoride
Whilst I don’t recommend fluoride free toothpaste, as you miss out on the known anti-cavity properties of fluoride, I respect that some people may still wish to avoid toothpastes containing fluoride.
In which case, there are two main options available to you:
- An SLS-free fluoride free toothpaste that contains no fluoride and no major source of remineralizing agent. Whilst ingredients like xylitol have a small anti-cavity effect, it would not be enough to be remineralizing in the same way as fluoride.
- An SLS-free fluoride free toothpaste that contains no fluoride and which does contain an alternative remineralizing agent. Calcium phosphates (such as hydroxyapatite) help reharden the tooth surface in a similar way to fluoride. These ingredients are newer than fluoride and are still undergoing long term studies, but have been FDA approved. They are normally more expensive than fluoride, but there is lots of evidence supporting their effectiveness.
If you are set on an SLS-Free and fluoride free toothpaste, these are two good options to chose from:
Boka toothpaste

BOKA toothpaste is SLS and fluoride free, but I have included it here because it is able to still provide some protection against cavities due to the addition of nano-hydroxyapatite.
Although the science behind this is still relatively new compared to fluoride, it is certainly a good alternative if you want to avoid fluoride altogether.
Pros
- Hydroxyapatite provides remineralisation effect and some protection against cavities
- Good for sensitive teeth
- No parabens, no artificial flavors
- SLS free
- Vegan
- Gluten free
- Subscription available to reduce costs
Cons
- No ADA recommended fluoride
Cleure Toothpaste

Cleure toothpaste comes in two different flavours, and both are fluoride free. But the reason I have recommended this toothpaste though is because it does contain calcium phosphate and xylitol, both of which help to protect teeth against cavities. So it is a good option if you want a non-mint fluoride free toothpaste.
At first this toothpaste seems expensive at $9 a tube, but the size of the tube is almost double that of a normal toothpaste tube, so it’s not so badly priced after all.
Pros
- Available as unflavoured or cinnamon flavoured.
- Free from artificial flavors and dyes.
- No parabens or harsh preservatives
- Gluten free.
- Naturally derived ingredients.
- Vegan and Cruelty Free.
- Ecologically responsible company.
- Calcium phosphate remineralizing agent
Cons
- No ADA-recommended fluoride

Hello kids toothpaste with fluoride

Hello toothpastes are all SLS-free, and their range includes two non-mint flavours which still contain fluoride: blue raspberry and strawberry.

Oranurse Unflavoured toothpaste

Oranurse toothpaste is SLS-free and non-foaming. I would recommend it as one of the best non-foaming toothpastes. It is also completely tasteless – which makes it perfect for kids (and adults too!).
Pros
- Completely unflavoured.
- SLS free – also non foaming.
- Vegan.
- Two different fluoride levels available.
- Suitable for a wide range of medical conditions.
Cons
- Difficult to get hold of due to production and supply issues.

Best SLS-free toothpaste for gingivitis / receding gums
If you have sore gums you may consider an SLS-free toothpaste to prevent further irritation, especially if you already have ulcers. I also recommend reading my post on the best toothpastes for gum disease.
Some toothpastes may also include further ingredients to help reduce the amount of gum disease causing bacteria. My recommendations would include:
- Jason Healthy Mouth Tartar Control Anti-Cavity Toothpaste – Tea Tree & Cinnamon (view on Amazon)
- The Natural Dentist Healthy Teeth & Gums Whitening Plus Toothpaste (view on Amazon)
- Therabreath PerioTherapy toothpaste (view on Amazon)

Can these SLS-free toothpastes be used to clean dental guards as well? So difficult to find a liquid to use on dental guards. Thank you for you input! Extremely helpful!
Hi Linda, I wouldn’t recommend using toothpaste on a guard as the abrasive ingredients can cause scratching. We will be releasing a page very soon about denture cleaners, which will also apply to retainers and dental guards, so keep an eye out for that. In the mean time, look in to denture cleaners for some top tips. Gemma
I have had BMS, BURNING MOUTH SYNDROME, for about 16 years. No one seems to know about it or what to do with me. I am 80 years old and everyday I get it, sometimes with ice water and then not so. And Gatorade and the Atkins drink HAD TO BE COLD or I will instantly burn my tongue, pallet and throat. Any ideas. Have tried various toothpastes and I think I am ok there. Thanks for any possible help or ideas. Cindy Harrell
Hi Cindy, this sounds very frustrating for you. As I haven’t assessed you I can’t make any specific medical advice, but I can give some general advice.
There is some basic information from Colgate, on this website and here.
Burning Mouth Syndrome often has an underlying cause, and if you haven’t done so, do have these investigated. Common causes are nutritional deficiencies such as iron deficiency anaemia. It is worth contacting your doctor to have blood tests to exclude common obvious deficiencies. Burning mouth symptoms can also be as a result of a dry mouth caused by medications, so review these with your doctor too, to see if any changes can be made. Symptoms can also start during times of hormonal changes for women. If you wear dentures or have any mouth infection, these can contribute too.
Dentists who are specialists in Oral Medicine will be best placed to help you (this tool will help you find a specialist close to you). If you cannot find an underlying cause, the focus is on managing symptoms. Some of this will be avoiding triggers. Common triggers are spicy foods, very salty foods, tomatoes, and chocolate, but every person is different. Managing stress and getting into a good sleep routine is usually recommended too. There are some medications which can help – these are medications used to treat anxiety, depression, and neuropathic pain. Again, I would recommend you visit a dentist who has secialised in Oral Medicine to help you with diagnosis, managing symptoms, and treatment.
I hope this is of some help.

I recently discovered that my daughter has a canker sore on her gum. So I am trying to find a SLS free toothpaste for her. I stumbled upon Dr. Brite toothpaste, and was wondering if you have done any research on this to know how effective it is. Thank you.
Hi Sarah. This isn’t a paste Dr Gemma Wheeler has researched at this stage. We will certainly consider it for future updates to this page, but can’t comment on it at this stage.
Do you get teeth staining with or without the ingredient SLS ?
I’m not sure what to buy, as this happened to me
Staining of the teeth is usually caused by lifestyle factors such as what you drink and eat and if you smoke. Certain ingredients in products can stain the teeth, but in toothpaste the ingredients are not designed to stain the teeth.
Thank you for this information.
I have Lichen Plantus and wish to know the very best toothpaste for this painful condition.
Hi Pat. We haven’t compiled a list of pastes best suited to this specific condition as yet. It would be worth taking a recommendation from your own dentist at this time.
My dentist at the hospital advised me to use any Sensodyne toothpaste. I’ve tried it but it is just as painful when brushing with a soft bristle toothbrush and makes my gums very sore. I have Lichen Plantus in the mouth and also spreading on my body in the form of blisters – usually 2-6 in each area it affects. I cannot find SLS free toothpaste at any high street chemist. Any suggestions please? Thanks you!
Hi Yvonne. I am afraid I can’t comment on the availability within specific high street chemists. Are you not able to purchase online for delivery to your door?
Hi Jon, I don’t know how to do the payments by paypal etc. Very bad with new tech BUT it’s my age I guess and not my intellgence 🙂
Hello, If possible, please advise the type of Arm and Hammer toothpaste which contains THE LEAST SLS. They say there is
no SLS, but it is listed in the ingredients.
Thank you for your help
Hi Rose.
We haven’t listed any Arm & Hammer products in this article (I don’t think).
Who is saying there is no SLS? Arm & Hammer themselves? If there was none, surely it would not be on the list of ingredients.
We do not have access to the amount of each ingredient they include and I am not sure the companies would give out this information.
Have you spoken to them directly to see what they say?
Hello. I am a 68 year old female with good oral heath.
My dentist has recommended that I use a a prescription toothpaste with the highest degree of Sodium Fluoride to supplement the twice daily use of CLOSYS with fluoride.
I started using PreviDent 5000 Plus as a supplement but just found out there is SLS in the PreviDent toothpaste. In the past, I have shown a great sensitivity to SLS by developing a high number of painful mouth sores.
Can you suggest an alternative to the PreviDent 5000 Plus since I seem to need the additional fluoride, as recommended by my dentist. Thanks for your assistance.
Alice.
We advise speaking directly to your dentist about this given your need for prescribed toothpaste. They can advise best based on your personal situation.
