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.
Why does toothpaste expire?
The Food and Drug Administration (FDA) doesn’t regulate expiration dates for over-the-counter toothpaste. However, because the FDA considers fluoride a drug, toothpaste that contains fluoride will include an expiration date on the packaging. Additionally, the American Dental Association (ADA) only gives its Seal of Acceptance to fluoride toothpastes, so all ADA-approved options will have an expiration date.
Toothpaste contains several ingredients that support oral health and enhance the brushing experience — such as fluoride, thickening agents, abrasives, detergents, sweeteners, and flavoring. Over time, these ingredients can lose their effectiveness or change in consistency. Tip: Once expired, fluoride compounds break down, making them less effective at fighting cavities and strengthening enamel.
Expired toothpaste may:
- Lose flavor
- Change color
- Harden or separate
- Become gritty or watery
- Be less effective at preventing tooth decay
What is the typical shelf life of toothpaste?
Toothpaste typically has a two-year shelf life from its manufacturing date. This is especially important if your toothpaste contains fluoride, as its enamel-strengthening properties diminish over time.
Keep in mind:
- Children's toothpaste may not contain fluoride and might not include an expiration date
- Even non-fluoride pastes can dry out or lose their taste after two years
- Always check the packaging for the expiration date
Is expired toothpaste safe to use?
While expired toothpaste won’t harm you, it also won’t do much good. The ingredients break down, so brushing with expired toothpaste won’t protect your teeth against cavities or decay as effectively. In some cases, very old toothpaste may even harbor bacteria.
Tip: Don’t toss it just yet! You can use expired toothpaste to:
- Polish metal
- Remove scuffs from shoes
- Clean your sink or bathroom fixtures
- Get rid of crayon marks on walls
- Buff your fingernails
How can I keep toothpaste fresh?
To extend the life of your toothpaste and keep it hygienic:
- Always close the cap or top tightly after use
- Wipe the edges clean to avoid buildup and contamination
- Store it in a cabinet to reduce exposure to air, dust, and humidity
- Keep it in a cool, dry place — heat can cause the ingredients to separate
Keeping your teeth healthy
Brushing with non-expired toothpaste is a great start to maintaining oral hygiene, but it's only part of the equation. You should also:
- Floss daily
- Avoid smoking, excess alcohol, and sugary drinks
- Limit snacking between meals
- Check expiration dates on mouthwash
- Replace your toothbrush every 3 to 4 months
And most importantly, visit your dentist regularly for professional cleanings and exams.
