How many years is the shelf life of toothpaste

Toothpaste does not have a shelf life. Many people think that toothpaste can be used continuously as long as it is not finished, and using a small amount each time can achieve a good saving effect. In fact, although toothpaste has a shelf life, the shelf life is still very long. It is recommended to use it up within one year, but few people will check the shelf life, especially for toothpaste after opening. It is very important to pay attention to the method of use.

Can I still use expired toothpaste?

If you ask a dentist about this specifically, he will tell you that toothpaste that has expired can still be used to brush your teeth and does no harm to your body. But doctors will also say that although it can be used, some of the benefits promised in toothpaste may disappear as it expires.

For example, fluoride is added to many toothpastes to protect tooth enamel and prevent tooth decay. Fluoride is a mineral required by the human body in trace amounts. It is involved in the formation and nourishment of bones and teeth and plays a decisive role. In addition, fluoride can prevent tooth decay.

If the acidic substances secreted by dental plaque continue to consume the minerals in the teeth, it will cause progressive damage to the hard tissues of the teeth, thus forming caries. Regular topical application of low concentrations of fluoride can speed up the growth rate and increase the size of enamel crystals, thus freeing the teeth from suffering from demineralization.

However, depending on the length of time the toothpaste has been expired and the environment in which it is stored, other chemical components in the toothpaste may also decompose, causing the taste to become strange, etc. So, given that the inside of your toothpaste is probably unrecognizable, it's time to get a new tube now that it's expired.

How long is the shelf life of toothpaste?

Many people have found when buying toothpaste that some toothpastes have a shelf life indicated on them, while others do not. It can be said with certainty that toothpaste has a shelf life.

After toothpaste is produced, the longer it stays on the shelf, the longer the fluoride it contains combines with other ingredients (such as abrasives and foaming agents), which directly results in a decrease in effective fluoride content and bioavailability. Studies have shown that the bioavailability of fluoride decreases most rapidly in the first few months after toothpaste is produced; before the toothpaste reaches its shelf life, the availability of fluoride may be very low. Sodium lauryl sulfate (SLS) reduces the bioavailability of fluoride.

Therefore, when buying toothpaste, try to avoid choosing toothpaste that uses sodium lauryl sulfate as a foaming agent. In addition, you should also consider buying toothpaste in a small capacity so that you can change it frequently. Pay attention to the expiration date and try to buy toothpaste with a closer date.

This simple tip can help improve your dental health, especially if you're prone to cavities.

The shelf life of general toothpaste is about two years from the date of manufacture. Over two years, the fluoride-containing ingredients may crystallize and lose their effectiveness. In addition, the longer a tube of toothpaste is used, the more it is exposed to the air and the greater the chance of contact with bacteria.
