When you get canker sores in your mouth or acne around your lips, the last thing you might suspect to have triggered it is your toothpaste. However, the Mayo Clinic lists dental products containing fluoride as a possible cause of perioral dermatitis – adult acne that covers the skin around the mouth and nose – and The Fluoride Action Network says fluoride toothpaste might also be the impetus for painful canker sores in the mouth and cheeks. Also, according to a January-March 2003 article in the "Swedish Dental Journal," sodium lauryl sulfate, SLS, might also contribute to canker sores.
Allergenic Ingredients
Along with the alleged allergenic properties of fluoride and SLS, "The Journal of Clinical and Aesthetic Dermatology" says certain toothpaste flavors frequently cause reactions, too. These include cinnamon, spearmint, peppermint, carvone and anethole. However, most toothpastes are flavored with either mint or spearmint, so people with those with allergies might have difficulty finding an acceptable brand. Nevertheless, there are a few fluoride-free toothpastes on the market that don't contain these potentially irritating ingredients.
Perioral Dermatitis
The American Academy of Dermatology says perioral dermatitis symptoms are small red bumps around the lips, nose and chin; however, the nose, eyes and cheeks can also be affected. These bumps might be pus-filled or peeling. The academy says the condition looks similar to acne and is sometimes accompanied by a mild itching or burning sensation. Additionally, The Mayo Clinic says perioral dermatitis might be a form of rosacea, adult acne or seborrheic dermatitis. The clinic lists makeup, moisturizers and topical corticosteroids as other potential perioral dermatitis triggers.
Canker Sores
Canker sores occur inside the lips and cheeks, at the base of the gums and under the tongue. They are typically red and sometimes have a white coating. Anyone can get canker sores, which are different from fever blisters, which typically occur on the outside of the mouth. Aside from irritating ingredients in toothpaste, other potential causes of canker sores are mouth injuries, stress, poor nutrition, food allergy and menstruation, says FamilyDoctor.org.
Diagnosis and Treatments
If you notice unusual bumps around your mouth, call your physician. The University of Maryland Medical Center says perioral dermatitis is difficult to treat and often requires several months of care. Your doctor might diagnose you simply by looking at your skin, or a bacterial culture might be necessary. If you are diagnosed with perioral dermatitis, your doctor might prescribe oral antibiotics or other topical medications to treat your condition, says UMMC. Unfortunately, the bumps might return, especially if skin creams containing steroids are applied to the face. As for canker sores, while there is no cure, the discomfort is eased by ibuprofen or acetaminophen, says Family Doctor. Canker sores typically go away on their own within seven to 10 days. Ask your pharmacist or doctor what she recommends to ease your discomfort.
