Yes — toothpaste can expire! Not only does it become less effective once it has passed its expiration date, but it’s also not exactly pleasant to brush with.
The Food and Drug Administration (FDA) doesn’t regulate expiration dates for over-the-counter toothpaste. However, as the FDA considers fluoride a drug, you’ll still be able to find an expiration date on your toothpaste’s packaging if it contains fluoride. Similarly, the American Dental Association (ADA) Seal of Acceptance is only given to toothpastes that contain fluoride, so all ADA-approved toothpastes include an expiration date.
But what should you do if you reach for your toothpaste only to realize that it is past its expiration date? Can you still use expired toothpaste? The short answer is yes — as long as no mold has developed — but in general, you probably shouldn’t.
Why Does Toothpaste Expire Anyways?
Toothpaste generally contains ingredients that can benefit your oral health and make the brushing experience more pleasant. For example, you may find cavity-fighting fluoride, thickening agents, whitening peroxide, antimicrobials, anti-sensitivity agents, detergents, abrasives, and humectants in your toothpaste.
To reap all the benefits of brushing with toothpaste, you’ll want to ensure all the ingredients are fresh. If your toothpaste contains fluoride — the mineral responsible for strengthening your enamel — it will become less effective at preventing cavities once the expiration date has passed, as the compounds in fluoride break down over time.
Toothpastes also include flavors, sweetening and moisturizing agents, detergents, and abrasives, all of which affect your brushing experience. For example, your toothpaste might change color, become less flavorful, harden, or develop an inconsistent texture over time.
What Is the Typical Shelf Life of Toothpaste?
Generally, toothpaste has a shelf life of two years from its manufacturing date before fluoride’s ability to strengthen and repair enamel significantly decreases.
Different kinds of toothpaste have different shelf lives, so double-check the packaging or tube for an expiration date. For example, children’s toothpaste doesn’t always contain fluoride, so it may not even have a printed expiration date. However, it’s still best to stop using it after two years, as it may dry out or change in color and taste.
Is Expired Toothpaste Safe to Use?
While expired toothpaste won’t hurt you, it also won’t help much. After its expiration date, the fluoride will be less effective in cleaning your teeth and preventing cavities, so it’s best to buy a fresh tube. Plus, older toothpaste may harbor bacteria or contain separated ingredients.
Luckily, you don’t have to immediately toss your old toothpaste! You can use it to buff fingernails, remove crayon markings from walls, polish metal, clean your bathroom sink, or even remove sticky residue from your iron.
How Can I Keep Toothpaste Fresh?
To keep your toothpaste fresh and germ-free:
- Close the top or replace the cap after each use.
- Wipe the edges of the tube to avoid collecting dust and bacteria.
- Store it in a cabinet to limit exposure to moisture and germs.
- Keep it in a cool environment, as heat can cause ingredients to separate or liquify.
Keeping Your Teeth Healthy
Brushing with non-expired toothpaste is a great starting point for maintaining oral health, but the work doesn’t end there. Be sure to:
- Floss daily
- Limit smoking and alcohol
- Reduce sugary beverages and snacks
- Replace your toothbrush every 3–4 months
- Check expiration dates on mouthwash
- Watch for signs of bacteria or fungi in over-the-counter rinses
