Can You Use Expired Toothpaste?

Using expired toothpaste isn’t necessarily dangerous. However, there are a few things you should keep in mind.

The most significant issue with expired toothpaste is its reduced effectiveness. When your toothpaste goes over the expiration date, fluoride can lose its potency. While it won’t hurt you, it won’t offer the same amount of protection against tooth decay.

In rare cases, there’s a slight possibility of microbial growth. Expired toothpaste can potentially harbor bacteria or fungi, especially if the tube has been left uncapped or improperly stored. This can increase the risk of introducing harmful bacteria into your mouth. 

How Does Fluoride Work?

Fluoride is an essential mineral for fighting tooth decay. The higher the amount of fluoride, the more protection it offers against cavities. 

Research shows that toothpaste must contain at least 1,000 parts per million (ppm) of soluble fluoride to be effective. However, fluoride breaks down over time and decreases in potency. 

When fluoride stops being effective, you increase the risk of developing cavities, weakened tooth enamel, and infection. Overall, it’s best to use toothpaste before the expiration date.

How Long Does Toothpaste Last?

Typically, toothpaste can last up to two years after it’s made. However, toothpaste can remain somewhat effective for a while beyond the date on the tube.

If it’s only been a couple of months past the expiration date, there's not much to be concerned about. Especially if the toothpaste looks, smells, and tastes normal.

However, as mentioned before, the effectiveness will decline over time. Additionally, several factors can influence how long toothpaste lasts, including the type of toothpaste, special ingredients, and proper storage. 

It’s a good idea to replace toothpaste every six months to ensure you get the most out of it. If it’s dried out, separated, or has a strange taste or smell, it’s time to get rid of it.

Tips To Keep Your Toothpaste Fresh 

If you want to keep your toothpaste fresh and bacteria-free, here are some things you can do:

• Seal it carefully — After use, seal the tube cap tightly. Keep the area around the cap clean to prevent germ and bacteria growth.
• Store it properly — Keep your toothpaste and toothbrush in a closed cabinet. Leaving them out in the open, especially near a toilet, may introduce bacteria.
• Keep it cool — Store toothpaste in a cool environment. Hot temperatures can separate ingredients.
• Replace it regularly — Replace the toothpaste with a fresh tube once it’s past its expiration date.

Practical Tips for Dealing with Expired Toothpaste

It can feel like a waste to throw out a tube of toothpaste, even if it is expired. But there are a few things you can do with a tube of expired toothpaste to make it worth your while. 

It can be used to clean chrome fixtures, remove crayon marks, or polish silver jewelry. However, to avoid unwanted damage, test it on a small area first.

Additionally, toothpaste can be used on topical burns and insect bites. One of the main ingredients in toothpaste is eucalyptus oil, which can have calming and antimicrobial properties.

You should also check if the tube is recyclable or compostable. Many brands offer eco-friendly packaging options, if you do decide to toss the tube.
