Sodium lauryl sulfate or “SLS” is an active ingredient that you’ll find in a lot of very popular toothpaste brands. But for some people, choosing an SLS-free toothpaste is important, because the SLS ingredients can make their mouth peel or tissues slough.
What is SLS (Sodium Lauryl Sulfate)
What Are SLS Free Toothpastes?
Whenever you’re choosing a toothpaste, check the box to see what it’s created for. Do you have concerns about whitening because of heavy stain? One for more sensitive teeth? Perhaps you are more concerned about your gum health? Knowing that each formula works differently will help you narrow down your choices, regardless of the brand, especially when you’re picking one without SLS. And when in doubt, always ask your dentist or hygienist.
6 Best Toothpaste Without SLS
If you want an SLS-free toothpaste, you have a few different options. What you’ll find with SLS-free toothpaste is that many of the blends are also free of other things like parabens, sulfates, and sometimes even fluoride. But the ones that don’t have fluoride in them will usually have something like xylitol or hydroxyapatite crystals instead, to help fight-off the “bad” bacteria and acids in your mouth. If you’re trying to whiten your teeth or manage sensitivity at the same time, it’s totally doable. Here are my top six picks to consider:
1. Bite Toothpaste Tabs in Fresh Mint
Best SLS Free Toothpaste
Bite uses nano-hydroxyapatite (n-Ha), which has been used in Japan for over 40 years. Powered by n-Ha, a 100% non-toxic ingredient that remineralizes and desensitizes teeth without triggering sensitivity.

Side Effects of SLS
Microscopically, sodium lauryl sulfate in toothpaste can act like an irritant to the inside of your mouth. That’s why SLS is listed as an active ingredient on the label. Most of us never have any problems using toothpaste with SLS. But some people will experience problems like:
- Peeling skin
- Burning sensations
- Redness
- Ulcers
- Symptoms that mimic gingivitis
- Sensitive teeth
Choosing an SLS-free toothpaste removes this common irritant, reducing or eliminating side-effects for individuals who tend to experience these symptoms. While not everyone is sensitive to SLS, enough people are that the label of your toothpaste has to include it as an active ingredient. Just like fluoride, SLS is specifically pointed out on the label, compared to some of the other ingredients listed on toothpaste packaging.
SLS and Teeth Sensitivity
If you have canker sores, sensitive teeth, or notice that your teeth are getting more sensitive after using an SLS toothpaste, you might want to switch to an SLS-free toothpaste instead. Sodium lauryl sulfate doesn’t just irritate delicate gum tissues, it can also increase the risk of tooth sensitivity for some people. You’ll more than likely notice symptoms in your gum tissues as well.
Using SLS-free toothpaste can help you rule out common sources of tooth sensitivity. Especially if you decide to switch to a sensitive teeth toothpaste that’s particularly formulated for sensitive teeth. For best results, you’ll probably want to use your newer toothpaste twice a day for two weeks before you see the full effects of the anti-sensitivity ingredients.
Why is Sodium Lauryl Sulfate (SLS) in Toothpaste?
SLS is almost like a type of detergent and is know for its foaming properties. As it foams and bubbles, it aids your toothbrush in removing plaque, leftover food debris, and acids on your teeth. It also works with the other ingredients inside of your toothpaste to hold all of them together, creating a nice, thick paste or gel that can withstand a bit of time on the shelf.
Sodium lauryl sulfate also has antimicrobial properties, helping reduce the “bad” bacteria in your mouth whenever it’s brushed onto your teeth and gumlines.
That being said, it’s ok to use an SLS-free toothpaste if it has the right ingredients in it. If you’re experimenting with different types of toothpaste and see one where SLS isn’t listed, you don’t have to worry about whether or not it’s still “good” for you or not. Remember, whatever toothpaste you use is still only as good as your brushing technique! The added ingredients are just extra perks to help with fresh breath, anti-cavity benefits, etc.
Other Irritant Ingredients In Toothpaste
SLS isn’t the only ingredient in some toothpastes that people are sensitive to. Other common active ingredients that might cause tissue sloughing, peeling skin, or sensitive teeth include:
Sodium dodecyl sulfate (SDS)
Sulfuric acid monododecyl ester
Does SLS Whiten Teeth?
SLS doesn’t necessarily whiten your teeth the way peroxide-based gels do, but it does help reduce surface tension across your tooth enamel to help make teeth cleaner, smoother, and less likely to accumulate stain buildup throughout the day.
If you really want to whiten your teeth, you’ll probably pick up a whitening toothpaste that has ingredients like hydrogen peroxide, carbamide peroxide, pyrophosphates, or even silica, which all help remove surface stains as you’re physically brushing your teeth. Using an SLS-free toothpaste won’t impact whether or not your toothpaste helps clean your teeth and remove surface stains (at least by very much.) However, you might still have sensitivity that aren’t caused by SLS, simply because of the teeth whitening ingredients included that may irritate sensitive teeth.
How To Properly Brush Teeth
The way you brush your teeth makes way more of a difference in your oral health than the type of toothpaste you pick at the store. For healthy teeth, you want to make sure you’re removing as much plaque as possible, fighting off gingivitis or gum disease, keeping your bad breath fresh, and reducing your risk of cavities and tooth decay, make sure you do the following:
- Brush no less than twice a day
- Brush at least two minutes at a time
- Focus along the gumlines, where plaque is heaviest (angle the bristles toward your gum tissues)
- Make short strokes on only one or two teeth at a time (brushing too wide or aggressively tends to cause the bristles to “skip” over several teeth)
- Brush the inside, outside, and chewing surfaces of all teeth
- Use a fluoride-based toothpaste
- Follow up with floss to clean areas between your teeth, that a brush won’t reach
The Best SLS Free Toothpastes
If the skin inside your mouth peels easily, you get frequent ulcers, or your teeth are sensitive, consider switching to SLS-free toothpaste. Not everyone is sensitive to sodium lauryl sulfate, but the people who are SLS sensitive tend to have tissue sloughing whenever they use toothpaste with SLS in it. As long as you’re choosing a fluoride toothpaste for anti-cavity purposes and brushing your teeth properly every time, it’s completely fine to have a toothpaste without ingredients like SLS.
