As a dental health specialist, I've been asked a lot about the safety and efficacy of using toothpaste that is past its expiration date. The American Dental Association (ADA) has set standards for toothpaste, including the requirement that any toothpaste containing fluoride must carry an expiration date. This is typically two years after the manufacture date.
Firstly, it's important to understand why expiration dates exist. They are there to ensure the product is at its peak performance and safety. Toothpaste, like any other product, can degrade over time. The active ingredients, such as fluoride, can diminish, which may reduce the effectiveness of the toothpaste in preventing cavities and promoting overall oral health.
Now, while using expired toothpaste may not pose a direct health risk, similar to how drinking expired milk might not immediately cause illness but can lead to spoilage and health issues if consumed over time, it's generally advised not to use toothpaste past its expiration date. The reason is that the fluoride, which is a crucial component for fighting tooth decay, may not be as potent. Fluoride works by making the tooth enamel more resistant to acid attacks from bacteria in the mouth, which leads to decay. If the fluoride has degraded, the toothpaste may not be as effective in protecting your teeth.
Additionally, other ingredients in toothpaste, such as abrasives that help remove surface stains and polish the teeth, can also become less effective over time. This means that not only might your toothpaste be less effective at cavity prevention, but it could also be less effective at maintaining the brightness and cleanliness of your teeth.
Moreover, the preservatives that are added to toothpaste to prevent microbial growth can also degrade over time. If the toothpaste is opened and exposed to air and moisture, the risk of bacterial growth increases, especially if it's been sitting on your bathroom counter for an extended period past its expiration date.
It's also worth noting that the consistency and taste of toothpaste can change over time. You might notice that it becomes harder to squeeze out of the tube, or that it has an unusual texture or taste. These are signs that the product is no longer at its best and it might be time to replace it.
In conclusion, while using toothpaste that is past its expiration date may not be immediately harmful, it is not recommended due to the potential decrease in effectiveness of its cavity-fighting properties. It's always best to use toothpaste within the recommended time frame to ensure you are getting the full benefits of its ingredients. If you're unsure, it's a good idea to replace your toothpaste to maintain optimal oral health.

The ADA now requires any toothpaste containing fluoride to carry an expiration date. Typically it is two years after the manufacture date. Now, while using expired toothpaste may not be as bad as say, drinking expired milk, it is probably best not to use it past the expiration date.May 29, 2013
