How long do crest white strips last before they expire

Teeth whitening strips do have the tendency to expire which is why it should be used regularly and the best before date should be checked upon purchasing it. It is not unsafe to use teeth whitening strips that have passed their expiration date, but it is not advisable from dental professionals. The strip itself tends to grow weak and it might even break when you start to use it. The whitening gel that the strip is coated with can also weaken which means that you will not get the bright smile that you hope for.

I would use them. They are only 1 month expired. You may or may not get the most potent white but will get enough. Don’t throw $ away.

Answer:

Crest Whitestrips keep for 24 months from the date they are made. You will find the expiration date for your Whitestrips, printed on the pack. Look for the text that starts EXP, and the letters that follow represent the month and the numbers the year the strips expire.

Answer:

I'm not sure. I will tell you, (BEWARE!) of this version of Crest white strips. This version "bonds" to your teeth like the strips were cemented on. Oh my God, I almost pulled all of my front teeth out trying to get the strips off. And, some of the strips have nothing on them. Good luck

Teeth whitening strips do expire (regardless of the brand name and manufacturer). Their shelf life is typically about one year. It’s, however, possible to extend their life by an additional year if stored in the refrigerator, although, freezing is certainly not recommended. If the setting on your refrigerator is too cold that the strips freeze, allow them to first cool down preferably to room temperature, before applying them.

If, however, the expiration date of the white strips was not too long ago, they still could whiten your teeth although not optimally. 

What Happens If Used After Expiration?

You don’t have to be too concerned about the safety of using expired Crest White Strips.  Using such expired products will not cause any harm to your teeth. However, using them is not recommended as the active ingredients may no longer be effective to guarantee good results.

The reason why using expired white strips is not recommended is because of the agents they use to bleach or whiten the teeth; these are usually unstable meaning that they come with a definite shelf life. Once the active ingredient degrades completely, it means that you might not get white teeth as you would if the white strips were used before their expiration dates. 

Are They Unhealthy In General?

Any beauty product that contains water expires more quickly compared to one with dry ingredients. Crest teeth whitening strips do contain water and like all beauty products that have water, they eventually will breed bacteria. This may have consequences on your dental and oral health.

Although whitening strips are generally quite easy to use, you should use them according to the instructions on the package or as directed by the oral health professional.

Conclusion

Whitening strips do have expiry dates. Once they have expired, their effectiveness in whitening is reduced significantly. Depending on how long they have expired, their ability to whiten your teeth may have been completely wiped out. But different from what the majority of people believe, using an expired whitening strip will not harm you, it only becomes ineffective.
