2. Expiration Dates Explained
Most teeth whitening gels will have an expiration date printed on the packaging. This date is crucial, as it indicates the period during which the product is expected to be effective. Here are some important points related to expiration:
- Quality Assurance: Manufacturers perform stability testing to ensure the product maintains its efficacy until the expiration date.
- Effectiveness: After the expiration date, the active ingredients may not work as effectively, resulting in less noticeable whitening results.
- Safety Concerns: Although using expired gel generally won't harm you, the effectiveness and safety cannot be guaranteed.

It's essential to inspect your whitening gel before use. If you notice any of the following, consider whether it may be expired:

To extend the life of your teeth whitening gel, consider the following storage tips:
- Keep it Cool: Store the gel in a cool, dry place away from direct sunlight and heat.
- Seal Properly: Always close the container tightly after each use to prevent air exposure.
