Can You Use Expired Toothpaste? Safety & Dental Risks

You can technically use expired toothpaste, but it is usually not a good idea.

Toothpaste is a common part of daily life. We use it without thinking much about the dates on the tube. But just like medicine or food, toothpaste has an expiration date. And there’s a reason for that.

Most toothpaste tubes have an expiration date stamped on them, but many people never even notice it. 

Why Does Toothpaste Expire?

There is more to toothpaste than just minty paste. It is a combination of ingredients and chemicals that cooperate. Fluoride is the primary one. Fluoride fortifies teeth and helps prevent cavities.

Other ingredients keep the toothpaste smooth, moist, and able to foam. Over time, these ingredients can break down.

Here’s what happens when toothpaste expires:

• Fluoride may lose strength.
• Paste can dry out or separate into liquid and solid.
• Taste might change.
• Texture may become gritty or too runny.

Studies show that the fluoride in toothpaste starts to lose effectiveness after the printed expiry date. According to Healthline, most toothpaste brands have a two-year shelf life because fluoride may deteriorate over time and lose its ability to prevent cavities. 

So while old toothpaste might still look okay, it may not protect your teeth as it should. And there is a rule for everything. You have to be mindful about using a straw after tooth extraction, so how can you not be mindful about an expired toothpaste? We didn’t think.

Is It Dangerous to Use Expired Toothpaste?

Usually, using expired toothpaste once or twice is unlikely to harm you. But using it long-term is risky.

The biggest concern is effectiveness. You are brushing your teeth to fight cavities, gum disease, and plaque. You risk developing dental issues if your toothpaste is no longer able to accomplish that.

Also, the flavoring and sweeteners in toothpaste can spoil over time. This could cause:

• Bad taste
• Burning or irritation in your mouth
• Allergic reactions in sensitive people

Expired toothpaste might also grow bacteria or mold, especially if stored in a humid bathroom.

Toothpaste is regulated as an over-the-counter drug because it contains fluoride. That’s why it has an expiry date. Drugs must continue to be safe and effective until their expiration date, according to FDA regulations.

How Long Does Toothpaste Last?

The majority of toothpaste expires two years after it is manufactured. The expiration date is marked on the box or on the crimp at the tube’s end.

Here’s an example:

• “EXP 08/2025” means it’s good until August 2025.

If you can’t find the date, check the texture and smell. If it’s dry, separated, or smells bad, don’t use it.

Are There Any Other Uses for Expired Toothpaste?

Don’t throw away your toothpaste just yet if it has expired. It can still be useful for non-oral purposes. People have used old toothpaste for things like:

• Cleaning jewelry
• Polishing silver
• Removing crayon marks from walls
• De-fogging mirrors

These are safe uses because you are not putting it in your mouth. But even for cleaning, avoid toothpaste with bleach or whitening agents past expiry. The chemicals could break down and damage surfaces.

What Should You Do If You have Used Expired Toothpaste?

If you accidentally used expired toothpaste, don’t panic. It’s unlikely to harm you right away.

But if your mouth feels irritated or you notice a weird taste, rinse your mouth with water. Throw away the old toothpaste.

To protect your teeth, replace your toothpaste as soon as possible.

How to Store Toothpaste to Keep It Fresh?

Proper storage helps toothpaste last longer. Follow these tips:

• Keep it firmly shut.
• Keep it somewhere dry and cool.
• Keep the cap on for as little time as possible.

If toothpaste sits open, it can dry out faster and pick up bacteria from the air.

Are Natural Toothpastes Different?

Some people use natural toothpaste without fluoride. These might expire even faster. Natural formulas often lack artificial preservatives. That means they can go bad sooner than regular brands.

So always check expiry dates, even on “natural” products.

When Should You Replace Toothpaste?

Here’s a good rule:

• Check dates every few months.
• Replace toothpaste right away if it smells odd or looks separated.
• Don’t stockpile toothpaste if you won’t use it in time.

Experts in oral health believe that one of the easiest methods to keep your teeth and gums healthy is to use fresh toothpaste.

The Bottom Line

Can you use toothpaste that is expired? Yes, technically, but it’s not a good idea.

Your teeth may not be thoroughly cleaned by old toothpaste. It could irritate your mouth, taste awful and feel strange. Always use brand-new toothpaste before its expiration date for optimal dental health.
