Why Do Some Toothpastes Cause Canker Sores? Understanding SLS and Other Culprits

Do you often experience painful canker sores despite brushing well? While the exact reasons for canker sores are complex, some commonly used ingredients in toothpaste and other oral care products have been identified as potential triggers. This article delves into the reasons why certain toothpastes cause canker sores and offers practical advice for prevention.

Common Culprits: Menthol and Sodium Lauryl Sulphate

Two of the most common culprits are menthol and sodium lauryl sulphate (SLS). Menthol, a minty compound, can irritate the lining of the mouth and lead to canker sores for some individuals. On the other hand, SLS, a synthetic detergent found in many toothpastes, can disrupt the protective layer of the mouth, leading to increased sensitivity and potential canker sores.

Prevention Tips: Avoiding Triggers and Promoting Oral Health

To help prevent canker sores, it is crucial to avoid certain foods and oral care products that can exacerbate the condition. Here are some tips:

What to Do:

Use a soft-bristled toothbrush. Drink cool beverages through a straw. This can help avoid irritating the sores. Eat softer foods. Opt for bland, easy-to-chew foods to minimize irritation. Get regular dental check-ups. Regular check-ups can help identify oral issues early and prevent canker sores. Eat a healthy, balanced diet. A diet rich in vitamins and minerals can support overall oral health and the body’s natural healing processes.

What Not To Do:

Avoid spicy, salty, or acidic foods. These can irritate the sores and cause discomfort. Avoid rough, crunchy foods like toast or crisps. These can physically irritate the soft tissues in the mouth. Avoid very hot or acidic drinks. Opt for cooler beverages to avoid further irritation. Don’t use chewing gum. It can irritate the mouth and delay healing. Avoid toothpaste containing sodium lauryl sulphate. Look for toothpastes labeled as SLS-free for a more gentle experience.

Natural Alternatives for Oral Care

If you are sensitive to SLS and find that it triggers canker sores, consider trying natural alternatives such as plant-based tooth powders. These can be found in health stores and online, and are suitable for those looking for a more natural approach to oral hygiene.

Two popular plant-based tooth powders are:

Proteith Solutions Healthy Gums Tooth Powder. Proteith Solutions Sport Tooth Powder.

Both of these products provide the necessary proteins and vitamins to support the healing process without the potential irritants found in conventional toothpastes.

Understanding Sodium Lauryl Sulphate (SLS)

Sodium lauryl sulphate (SLS) is a synthetic detergent commonly found in toothpastes, shampoos, and cosmetics. It is known for its effectiveness in cleaning, but it can also be harsh on the skin and mucous membranes. SLS affects the barrier function of the skin by enhancing permeability. This can lead to increased sensitivity and irritation, which can contribute to the development of canker sores.

While SLS may be effective in oral care products, it is important to be aware of its potential to cause irritation. Alternatives such as SLS-free toothpastes and natural oral care products can be more gentle on the mouth and reduce the risk of canker sores.

By understanding the reasons why certain toothpastes cause canker sores and taking steps to avoid triggers, you can help prevent these painful mouth ulcers. Prioritizing your oral hygiene routine and using gentle products can make a significant difference in your oral health and overall well-being.
