Those of us who cannot tolerate gluten must watch everything we put in our mouths (even if we're not supposed to swallow it). So yes, we need to worry a little about gluten in toothpaste.
Fortunately, there's an abundance of gluten-free toothpaste options available in fact, the odds are good that the one you're using right now is considered gluten-free to the generally accepted limit of 20 parts per million.
Here's a rundown of major toothpaste manufacturers, their statements on gluten in toothpaste, and their gluten-free products:
Arm & Hammer toothpaste. Arm & Hammer verifies that its toothpaste products are gluten-free.
Aquafresh toothpaste. Aquafresh products, which include adult and kids' toothpastes plus whitening trays, do not contain gluten, according to the company.
Biotène toothpaste. Biotène makes products designed to help manage the symptoms of dry mouth, a common problem in Sjögren's syndrome, an autoimmune condition linked with celiac disease. Biotène states that all of its products are gluten-free.
Crest toothpaste. Crest, a Procter & Gamble company, states that all of its toothpaste products are currently gluten-free (as of January 2012). However, if you're looking for a gluten-free mouthwash, the company states that "Crest Pro-Health Rinse does not directly add any ingredients that contain gluten, though it is possible that it may contain trace amounts."
