Does Toothpaste Expire, and Is It Safe to Continue Using It?

Toothpaste expires, but using toothpaste past its expiration date isn’t harmful. It just isn’t beneficial. That’s because the active ingredients become less effective over time.

Both the U.S. Food and Drug Administration (FDA) and the American Dental Association (ADA) require toothpaste to have an expiration date. Each individual tube of toothpaste should have its own expiration date printed on the box and tube. It’s usually about two years after the toothpaste was manufactured.

Expiration dates explained

Toothpaste’s expiration date is mainly due to its active ingredient, fluoride. Research shows that fluoride may degrade and become less effective at preventing cavities over time.

Fluoride is the main ingredient that helps fight cavities and keep teeth healthy. It works by supporting healthy tooth enamel. Enamel is the shiny, white, visible part of the tooth, and it’s the tooth’s first line of defense against decay.

Preventing enamel loss is extremely important because once enamel is worn down (by decay and other environmental damage), it can never grow back.

The FDA requires an expiration date on all food and medicine to ensure safety and quality. When toothpaste contains fluoride to fight cavities, the fluoride is considered a drug, so the FDA regulates expiration dates on fluoride toothpaste.

The ADA also sets national standards for dental practices across the country, including toothpaste expiration dates. You should only buy toothpaste with the official ADA Seal of Approval. The ADA regulates quality and safety of all dental practices and products.

Toothpaste is a huge part of global oral health practices, but it’s not as important as simply brushing your teeth. The friction and movement of tooth brushing is the most important way to clean teeth as well as prevent cavities and decay.

That said, dentists always recommend toothpaste because it contains ingredients that benefit oral health.

Toothpaste usually contains:

fluoride to support healthy tooth enamel and fight cavities

detergents and abrasives to remove plaque buildup

antisensitivity agents to make teeth less sensitive

antimicrobials to prevent buildup (plaque), which causes cavities

flavor

humectant, which keeps toothpaste moist

thickening agents

peroxide to remove tooth stains

Tips for oral hygiene

Oral health is closely linked with overall health. This link is currently a hot topic for science and research.

Experts recommend these tips for optimal oral health:

Brush your teeth twice a day, with fluoride toothpaste, for two minutes each time.

Floss (it doesn’t matter if you floss before or after brushing).

Don’t snack between meals.

Don’t drink sugary beverages.

Don’t smoke.

Limit your alcohol intake.

As for other dental products:

Floss doesn’t expire but may lose its flavoring over time.

Prescription mouthwash expires. Over-the-counter mouthwash technically doesn’t expire, but it’s very likely to start growing bacteria or fungi. Always pour mouthwash into a separate cup before using it to prevent germs from sticking on the bottle.

Replace toothbrushes every three to four months (unless you get sick and vomit, in which case you should brush your teeth and toss the toothbrush).

Many dentists recommend both flossing and using mouth wash. But if you choose one, dental professionals still recommend flossing over mouthwash, except in cases where a prescription mouthwash may be recommended to treat a specific condition.

What can I do with my expired toothpaste?

If your toothpaste has expired, don’t use it to brush your teeth. Instead try toothpaste for:

polishing metal

cleaning the bathroom sink

removing crayon from walls

removing gummy residue off the bottom of an iron

buffing your fingernails

The Takeaway

Toothpaste expires because it contains fluoride, which may degrade over time. Fluoride is the active ingredient in toothpaste that fights cavities.

Both the FDA and ADA set regulations and standards for toothpaste expiration dates. Check printed expiration dates before purchasing or using toothpaste.
