With the start of the new year, many people are working on fresh goals and routines. We hope one of your resolutions is to keep up good oral health. To help with this, take a look at your oral hygiene supplies, then toss out the old and bring in the new!

Which dental products expire and how often should you replace them?

🦷 Toothbrushes – The building block of all of our at-home oral health routines does not expire. However, once you use it, it should be replaced every three months or once the bristles become frayed.

🦷 Toothpaste – The expiration date for toothpaste is listed on the tube. It is typically about two years after it is manufactured. Though it is not dangerous to use expired toothpaste, it will be less effective as the fluoride will lose strength. The taste might also be off as the flavoring fades.

🦷 Floss – Dental floss does not expire. Don’t use this as an excuse to forget this step in your routine! As it ages, the flavor might not stick around, but it will still clean out the hard to reach areas between your teeth and around your gums, as long as you use the proper technique.

🦷 Mouthwash – Product packaging will show the expiration date. Usually, this is two to three years after it is made. Expired mouthwash will lose its effectiveness because the alcohol or antiseptic will begin to dissolve. This leaves only water in the container, which will not be strong enough to kill the bad bacteria in your mouth.
