Toothpaste allergies are very abnormal, but they certainly can arise, especially if you have brushed your teeth with the same kind of toothpaste for a long time. When they do occur, patients typically have four kinds of allergic reactions:

-Reactions inside the mouth: Sensitive teeth or gums, tongue swelling, redness or mouth sores

-Reactions just outside the mouth: Dry or cracked lips, inflamed corners of the mouth

-Hives or Body Rashes: Hives or skin rashes anywhere on the body.

-Anaphylactic Shock: Swelling around the throat or tongue and blocks the airways and results in anaphylactic shock. Symptoms include stomach pain, blood pressure drops, and difficulty swallowing or breathing. In this case, get medical health immediately.

Do you want to know what toothpaste ingredients may cause your reaction? Any ingredient can be the stimulus, but here are the more ordinary culprits:

-foaming agents like cocamidopropyl betaine and sodium laurly sulfate

-flavorings such as mint or bubblegum

-essential oils or antibacterials like propolis or tea tree oil

-preservatives, including propylene glycol and parabens


If you’ve noticed any of these symptoms and you see any of these ingredients in your toothpaste, don’t jump to conclusions. The signs of a toothpaste allergy can be parallel to the adverse reactions to totally dissimilar products, or it’s possible it may not be an allergy at all. An allergist or general practitioner can do the official diagnosis. If you have already gone through that process and are not sure how to take care of your teeth, talk to Dr. Michael Kim and his associates at Michael Kim, DDS by calling 262-241-5558.
