Does Toothpaste Ever Expire?

Most people don’t put too much thought into their toothpaste. For something that we use orally every day, perhaps we should! Toothpaste, like many other odd things, does indeed expire. So, let us tell you why:

Fluoride Potency

The expiration date on most toothpastes is mainly due to it’s active ingredient, fluoride. Fluoride is important to our oral health because it helps with remineralization of the enamel that protects our teeth from cavities. Studies show that fluoride loses its anti-cavity efficacy over time. Toothpaste needs at least 1000 ppm of soluble fluoride to have an anti-cavity effect. According to the American Dental Association (ADA) any toothpaste that has fluoride must have an expiration date to have the official ADA Seal of Approval. The United States Food and Drug Administration (FDA) also requires that all food and medicine have an expiration date to ensure quality and safety. Using expired toothpaste past its expiration date is not known to be harmful, but it isn’t as beneficial. If you plan on stocking up on some discounted toothpaste, be sure to check for the expiration date on the bottom of the package.
