Reactions to Toothpaste

Even your favorite toothpaste can lead to allergic reactions, mouth sores and other types of ailments. Fortunately, most reactions are not serious and can be prevented by switching toothpaste brands. However, some reactions can be more serious and require a doctor's care. If you start to notice a reaction regularly after brushing your teeth, switch to a different brand to test your theory.

  1. Canker Sores

    • There are brands of toothpaste and mouthwash that contain Sodium Laurel Sulfate, or SLS, which is a foaming agent. SLS can have a drying effect on the oral tissue in your mouth and this leaves the area of the mouth susceptible to acidic foods and other irritants. As a result, you might develop canker sores which are painful ulcers that form inside the mouth.

    Allergic Reactions

    • Some people can have allergic reactions to toothpaste. The reactions are usually caused by ingredients in the toothpaste such as spearmint flavoring or peppermint oil. Allergic reactions to toothpaste can include swelling of the mouth area, redness of the gums, dry mouth or an infection in your mouth. These symptoms, if caused by a toothpaste allergy, will clear up by switching to another brand of toothpaste. If you have food allergies, such as gluten or dairy, you may be susceptible to ingredients that can often be hidden in toothpaste. For example, some toothpastes can contain grain-derived sorbitol, which may cause reactions in those who are gluten-intolerant, or recaldent, which contains milk protein and can cause reactions in those who are allergic to dairy.

    Circumoral Dermatitis and Cheilitis

    • There are more serious reactions including Circumoral Dermatitis, more commonly known as acne rosacea or Cheilitis which is an inflammation and cracking of the lips. These reactions have been related to tartar control toothpastes. If you experience these reactions, you may begin having burning and itching around your mouth. Within two weeks, you may begin to experience redness and swelling also known as erythema. These conditions generally clear up when the individual switches to another brand of toothpaste.

    Tooth Enamel

    • Whitening toothpaste contains abrasives and chemicals that remove stains and polish the teeth. These whitening toothpastes can be used alone or in conjunction with a bleaching procedure. According to the Mayo Clinic, excessive use of whitening toothpaste can cause damage to tooth enamel.

    Perioral Dermatitis

    • Some people may experience an ailment known as Perioral Dermatitis which can be associated with toothpastes that contain fluoride. This type of dermatitis may include a burning sensation around the face coupled with bumps or some type of rash. Perioral Dermatitis affects mostly women between the ages of 20 to 45. Topical treatments will generally alleviate the symptoms. However, sometimes an antibiotic may be necessary.
