Best SLS-Free Toothpaste

When it comes to selecting the best SLS-free toothpaste, there are various options tailored to specific needs. Here are our top recommendations:

Best overall: Hismile

Our top pick for SLS-free toothpaste is the Hismile Toothpaste, which is available in an array of absolutely delicious flavors, including watermelon, grape, vanilla, mango, peach, coconut, cake, strawberry, banana and mint.

We chose this toothpaste because it continues a unique fluoride+ formula that includes xylitol for extra help fighting cavities. Additionally, this toothpaste does NOT contain Sodium Lauryl Sulfate, but it does contain Sodium Lauroyl Sarcosinate (which although sounds similar is not really at all).

This is critical because SLS is what makes toothpaste foam, and the foaming isn't just for fun — it enables the beneficial ingredients of the toothpaste to get between teeth and clean along the gumline. So when you take SLS out of the picture, you are also decreasing the cleaning power of your toothpaste.

So Hismile added Sodium Lauroyl Sarcosinate to their formula, which still provides foaming action, but it does not cause sensitivity and irritation in the same way that SLS does. Sodium Lauroyl Sarcosinate has been approved by the Cosmetic Ingredient Review as a product that doesn't cause irritation.

Key benefits:

  • Fights cavities with fluoride
  • Tastes amazing
  • Hydrates and soothes oral tissues
  • Prevents sensitivity

Best for whitening: Snow

Sodium lauryl sulfate: Safe or not?

Sodium lauryl sulfate (SLS) is a common ingredient in many toothpaste brands, because it is a very effective foaming agent — and when toothpaste foams, it's able to better reach all of the corners of your mouth. However it can have adverse effects on oral health in some people. SLS can cause mouth irritations, dryness, and even exacerbate conditions like canker sores. Choosing SLS-free toothpaste can help reduce the risk of these issues.

That being said, the only known adverse side effect of SLS is irritation, and the FDA has found it to be safe for use in personal care products.

Conclusion

Selecting the right toothpaste goes beyond simply opting for an SLS-free option. It involves considering your specific oral health needs. Whether you're looking to prevent cavities, soothe canker sores, whiten your teeth, or address sensitivity, there's an SLS-free toothpaste for you. Make an informed choice based on your oral health requirements to achieve a beautiful, healthy smile.
