Why Choose SLS-Free Toothpaste?

Evidence note: who may benefit from SLS-free toothpaste

SLS-containing toothpaste is safe for most people. An SLS-free formulation may reduce pain, duration or frequency of recurrent aphthous ulcers in some susceptible patients, but the evidence base is limited and product formulations differ. Environmental claims cannot be inferred from the absence of SLS alone. Choose toothpaste primarily by fluoride concentration, caries risk, abrasivity, sensitivity needs and individual tolerance; persistent ulcers require diagnosis rather than repeated product switching.

As dental professionals, we are often asked about toothpaste recommendations for patients with sensitive mouths or recurring oral issues. Sodium lauryl sulfate (SLS) is a surfactant that creates the foaming action in toothpaste. While it is a common ingredient in many toothpastes, there are compelling reasons to consider SLS-free options for certain patients. These are also marketed as preservative-free toothpastes.

Reduced Irritation and Sensitivity

SLS can be irritating to some patients' oral tissues. Studies have shown that SLS-free toothpastes may be beneficial for patients prone to:

• Recurrent aphthous ulcers (canker sores)
• Dry mouth
• Oral mucosa sensitivity

A clinical study published in the Journal of Dentistry found 4 times fewer soft tissue lesions after 30 minutes when using an SLS-free toothpaste compared to one containing SLS.

Improved Taste Perception

SLS can alter taste perception, leading to the unpleasant "orange juice effect" after brushing. SLS-free formulations allow patients to enjoy foods and beverages sooner after brushing without taste distortion.

Gentler Cleaning Action

While SLS creates abundant foam, it is not necessary for effective cleaning. SLS-free toothpastes use alternative mild surfactants or ingredients like baking soda to remove debris and plaque. They clean teeth effectively without the potentially harsh effects of SLS.

Environmentally Friendly

Many consumers are becoming more environmentally conscious and prefer products that align with their values. SLS is derived from palm oil, which has been linked to deforestation and habitat destruction. By choosing an SLS-free toothpaste for your patients, you may be supporting more sustainable practices.

Benefits for Specific Patient Groups

Consider recommending SLS-free toothpaste for:

• Patients with recurrent aphthous stomatitis
• Those experiencing dry mouth
• Pregnant women with increased oral sensitivity
• Young children with delicate oral tissues
• Those with sensitive gums
• Anyone reporting stinging or irritation from regular toothpaste

Balanced Oral Microbiome

Some SLS-free toothpastes are formulated to support a healthy oral microbiome. For example, Enafix, Glodent, SHY-NM toothpaste has been shown to shift the oral microbiome towards a healthier state.
