The most common adverse reaction caused by toothpaste is contact allergy, which is more common in women than men. Currently, about 30 allergens have been identified in toothpaste, and these ingredients are present in the vast majority of toothpaste products. Contact stomatitis caused by toothpaste allergy often manifests as flaky hyperemia, erythema, mucosal ulcers, peeling or swelling of the mucous membranes of the lips, cheeks, tongue, and gums. Patients often visit a doctor for symptoms such as mucosal pain, numbness, and swelling that persist for different periods of time. Symptoms can last from several months to a few days, and are often aggravated when eating or brushing teeth. Once the symptoms of suspected toothpaste allergy appear, it is recommended to stop the toothpaste with suspected allergy at the first time, switch to ordinary fluoride toothpaste or children’s toothpaste, and bring the suspected allergy toothpaste to a professional department for treatment, under the guidance of a doctor. Commonly used drugs for treatment include topical corticosteroids, anti-allergic drugs, etc. The specific treatment plan should follow the doctor’s advice. During the treatment, avoid local irritation such as spicy and irritating food or hot food. Generally speaking, it can be relieved and healed within 1 to 2 weeks. In conclusion, toothpaste allergy is becoming more and more common, and identifying the toothpaste allergen and avoiding the use of toothpaste products containing this ingredient in the future is the only way to avoid the recurrence of similar symptoms.
