Last Updated on 15/11/2023 by Liz @ HealthTenfold


Sodium lauryl sulfate (SLS) is a common ingredient found in many personal care products, including toothpaste. While it serves as an effective foaming agent, some individuals may develop an allergic reaction to it. In this article, we will explore the sodium lauryl sulfate toothpaste allergy symptoms and discuss ways to manage this sensitivity for a healthier oral care routine.

Understanding Sodium Lauryl Sulfate

Sodium lauryl sulfate is a surfactant, known for its ability to create lather and foam. It is widely used in various personal care products like shampoos, soaps, and toothpaste due to its cleansing properties. However, for some individuals, prolonged exposure to SLS can lead to an allergic reaction.

Identifying Sodium Lauryl Sulfate Toothpaste Allergy Symptoms

Individuals with an allergy to SLS may experience a range of symptoms upon exposure to toothpaste containing this ingredient. These symptoms can vary in severity and may include:

Oral Irritation: One of the most common sodium lauryl sulfate toothpaste allergy symptoms is oral irritation. This may manifest as redness, swelling, or tenderness of the gums, tongue, or inner cheeks.

Mouth Ulcers: Some individuals may develop small, painful ulcers in their mouth as a result of the allergic reaction. These ulcers can make eating and speaking uncomfortable.

Dry Mouth: SLS can potentially cause dryness in the mouth, leading to discomfort and difficulty in swallowing.

Skin Rash Around the Mouth: In more severe cases, individuals may experience a skin rash around the mouth, extending to the cheeks or chin. This can be itchy, red, and sometimes accompanied by small bumps.

Burning Sensation: Those with an SLS allergy may experience a burning sensation in the mouth after using toothpaste containing this ingredient.

Taste Alterations: Some individuals might notice a metallic or bitter taste in their mouth after using an SLS-containing toothpaste.

Managing Sodium Lauryl Sulfate Toothpaste Allergy Symptoms

If you suspect that you may be sensitive to sodium lauryl sulfate in toothpaste, it’s essential to take proactive steps to manage your symptoms. Here are some practical tips:

Switch to SLS-Free Toothpaste: Opt for toothpaste that is labeled as SLS-free. Many dental brands offer alternative formulations that do not contain this ingredient.

Read Labels Carefully: Always read the ingredient list on oral care products. Look for alternatives to sodium lauryl sulfate, such as coconut-derived surfactants.

Consult a Dentist or Allergist: If you experience persistent symptoms, consult a dentist or allergist for a professional evaluation. They can provide tailored advice and recommend suitable products.

Maintain Oral Hygiene: Regardless of your sensitivity to SLS, maintaining good oral hygiene is crucial. Brushing, flossing, and regular dental check-ups are essential for a healthy mouth.

Consider Natural Alternatives: Explore natural and organic toothpaste or toothpaste tablets options. These often utilize milder surfactants and are free from synthetic additives. 

Rinse Thoroughly: After brushing, make sure to rinse your mouth thoroughly with water to remove any residue from the toothpaste.

Monitor Your Diet: Certain foods and beverages can exacerbate oral sensitivity. Spicy or acidic foods, for example, may increase discomfort. Pay attention to what you consume and make adjustments as needed.
