Do You Have a Toothpaste Allergy?

The most common toothpaste allergy symptom is cheilitis, which means inflammation of the lips. Cheilitis might display as dermatitis around the mouth, including a rash and dry, cracked lips. In some cases, you might also experience sensitivity or a mild burning sensation.

With toothpaste allergies, symptoms inside the mouth are very rare. You should see your dentist or primary care physician immediately if you experience any itchiness or swelling in your mouth. You might have a food allergy or a different oral health problem instead.

Toothpaste contains several ingredients that can cause irritation or even, in rare cases, an allergic reaction. The most common culprit is flavorings and essential oils, such as peppermint, spearmint, or cinnamon flavor. Other, less common causes include:

• Preservatives and Additives, such as certain chemical preservatives, parabens, or artificial sweeteners; 

• Surfactants and Foaming Agents, like sodium lauryl sulfate (SLS) or cocamidopropyl betaine; 

• Active ingredients that fight cavities, including fluoride. 

• Stabilizers like gluten, which also thickens the toothpaste.

Talk to your dental professional about any allergies or sensitivities you might have and ask about the best toothpaste for you.

Are you experiencing swollen and cracked lips or dealing with a rash around your mouth? If you think you're allergic to your toothpaste, then switch immediately. Try a different flavor or brand to see if the symptoms resolve. Your dental professional can help you find the right product.

If the problem persists, then reach out to your dentist or primary care physician. They might refer you to an allergist, who can perform tests to determine which ingredients or materials are causing the irritation. Or you might learn that your reaction is due to sensitivity to a new lip balm or facewash. In any case, once the offending ingredient is identified, you can avoid it in the future and get on with taking care of your healthy, radiant smile.
