There’s nothing worse than heading to the bathroom, ready to get rid of your morning breath and realizing that you have no toothpaste left! But wait! Maybe you’ve managed to rummage up a tube somewhere only to realize that it’s expired! Is it safe to use?
In this blog post, I’ll answer all your questions about expired toothpaste, including “Does unopened toothpaste expire?” (the answer is yes), “Is using toothpaste that’s expired safe?” (also, usually yes), and “How long does toothpaste last after its expiration date?” (It depends).

Without any further delay here’s everything you need to know about expired toothpaste.
Does Toothpaste Really Expire?
Like, really? (Yes, really). Toothpaste does absolutely expire, especially when it contains fluoride. This is why both the FDA and ADA require that toothpaste have an expiration date.
When Does Toothpaste Expire?
In most cases, toothpaste expires around two years or so after its date of manufacture. To confirm when your tube of toothpaste expires, look on the crimped end of the tube. You’ll normally find the expiration date there. Sometimes, however, it’s on the box instead of or in addition to being on the end of the tube.
Has your toothpaste been sitting in a drawer or cabinet forgotten for a while? Be sure to check its expiration date before using it!
What Happens When Toothpaste Expires & Can You Use Expired Toothpaste?
Toothpaste’s flavor, texture, consistency, and most importantly, efficacy all can change over time, especially after its expiration date.
But does any of that mean that you can’t use expired toothpaste? The answer to that question isn’t as clear-cut as you might think. That’s because, yes, you can generally use expired toothpaste, and no, it’s not normally too much of a safety risk.
However should you use expired toothpaste? No. That’s because in most cases, expired toothpaste is not as effective as new toothpaste. For instance, fluoride toothpaste in particular loses its anticavity properties over time.
In other words, while it may be safe to use expired toothpaste, it might not protect your teeth from decay or strengthen enamel in the way that it should.
In a pinch, with no other options available, you can usually feel free to use expired toothpaste once or twice. But you should pitch it ASAP and get a new tube to help protect your teeth and gums over the long-run!

How Long Does Toothpaste Last After its Expiration Date?
Toothpaste might still be usable for up to 6 months past its expiration date, if it was stored correctly, and not opened. That said, its effectiveness drops significantly after the expiration date – it’s there for a reason. The longer you wait to use it, the more risk involved. Fresh toothpaste that’s unexpired simply offers the best protection.
Signs It’s Time to Replace Your Toothpaste
Here are some indicators that it’s time to get a new tube of toothpaste!:

FAQs
Does fluoride toothpaste expire or go bad?
Yes, toothpaste does expire. Most formulas—especially fluoride toothpaste—have a shelf life of about two years. Over time, the active ingredients break down, which means toothpaste can go bad in terms of effectiveness, even if it still looks normal.
What happens if I use expired toothpaste?
Using expired toothpaste isn’t typically harmful, but it won’t work as well. The fluoride may no longer effectively strengthen enamel or prevent cavities, so you’re brushing without getting the full protective benefit.
Is expired toothpaste dangerous?
In most cases, expired toothpaste is not dangerous. However, it may have an off taste, altered texture, or reduced cleaning ability. The real concern isn’t safety—it’s that your oral health may suffer if you rely on it long-term.
How long is toothpaste good for after the expiration date?
Toothpaste may still be usable for a few months after the expiration date if stored properly, but its effectiveness declines quickly. If you’re wondering how long toothpaste is good for, sticking within the two-year window is your safest bet.
Can you use toothpaste after 2 years?
You can, but it’s not recommended. After two years, the toothpaste expiration date has passed, and the product won’t deliver the same cavity protection or enamel support.
Is 10 year old toothpaste still good?
No—10-year-old toothpaste is far beyond its usable life. At that point, the ingredients have degraded significantly, and it should be discarded.
How do you know if toothpaste is bad?
Signs toothpaste has gone bad include changes in texture, unusual smell or taste, separation of ingredients, or being well past the expiration date.
