What is Sodium Lauryl Sulfate (SLS)?

Before jumping into options for an SLS Free Toothpaste, let's first understand Sodium Lauryl Sulfate, aka SLS. 

SLS is a common ingredient found in almost all toothpastes, and is also a major ingredient in other cleaning products such as soaps, shampoos, detergents, handwash, face gels, shower gels, and more. 

It is a surfactant which cleans the surface which it comes in contact with, and is also a foaming agent which produces lather. 

It is an extracted synthetic product from coconut and palm oils, and also has antimicrobial properties. 

Being inexpensive to make, and effective in most situations, it is widely used for its foaming and cleansing properties. 

However, there has been an increasing concern about potential harmful effects and its impact on oral health. 

SLS is not recommended in food. Yet, certain food items do contain SLS within limits approved by the FDA. As per the American College of Toxicology, SLS may not be as harmful when used occasionally, however, in products with prolonged use, their concentration should be no more than 1%.

Why Is Sodium Lauryl Sulfate (SLS) Used in Toothpaste?

SLS is commonly used in toothpaste for several reasons.

1. Surfactant & Foaming: 

Firstly, it acts as a surfactant, which means it helps to create foam and spread the toothpaste evenly throughout the mouth. 

The foaming action helps to dislodge food particles and debris from the teeth, making them easier to clean.

And of course, people prefer a toothpaste which foams well

2. Cleansing Properties

Secondly, SLS has detergent properties, which aid in the removal of plaque and stains from the teeth. 

It helps to break down the sticky biofilm that forms on the teeth, which can contribute to tooth decay and gum disease.

3. Feels good: 

Lastly, SLS also enhances the overall texture and mouthfeel of the toothpaste. 

It creates a smooth and creamy consistency that many people find pleasing when brushing their teeth.

Being familiar with this, the feeling becomes habitual, and people may feel their brushing experience to be incomplete without this. 

What are the effects of SLS on the oral cavity?

A higher concentration of SLS in toothpaste can irritate the skin and can cause contact dermatitis. Other potential side effects include the following:

  • Mouth Ulcers: Also called recurrent aphthous ulcers, these are painful conditions which cause a break in the epithelial lining of the mouth and form ulcers. SLS also slows down the healing process of ulcers.
  • Limits Fluoride Availability: The increased concentration of SLS decreases the deposition of fluoride on the tooth surface. This mitigates the protective function of fluoride, which works to strengthen tooth enamel.
  • Altered Taste: SLS interferes with taste buds of the tongue and can change taste perception. The effect can last up to 4 hours, and is evident when having  citrus fruit juices right after brushing with an SLS toothpaste.
  • Burning Sensation: Some people complain of a burning sensation in the inner parts of the lips, cheeks, and tongue. It may also result in dryness of the mouth.
  • Reduces Mucosal Thickness: Mucosa is the lining of the skin of the oral cavity and has a protective function. Various studies have shown a considerable reduction in the thickness of mucosa.

What is an SLS Free Toothpaste?

Numerous brands offer SLS free toothpaste options which best suit sensitive cheeks and gums

These do not foam like their SLS counterparts, and when switching to the SLS free version, one can feel the difference. 

A toothpaste without SLS uses alternatives, such as polyethylene glycol esters of stearic acid. This is also a common surfactant, and is ideal for those with mouth ulcers.

Such toothpastes rarely cause mouth ulcers, and prevent inflammation of gums, in comparison with toothpastes having SLS. 

To sum up, an SLS free toothpaste can effectively clean the tooth, but without the foaming effect. 

What are the benefits of an SLS Free Toothpaste?

An SLS Free Toothpaste mitigates the potential risks associated with use of SLS, without compromising on oral care. The benefits include:

  • Preventing abrasive action of SLS, which can lead to eroding of tooth surface
  • Reduced risk of mouth ulcers, and assistance with speedy recovery
  • Prevention of gum inflammation
  • Presence of alternative active ingredients which help clean the tooth surface
