Does Toothpaste Expire?
Toothpaste does expire, typically 2 years after manufacture. After expiration, the fluoride becomes less effective and the paste may dry out, separate, or change texture. Expired toothpaste is not harmful but may not clean or protect teeth as well. Replace expired tubes for best dental care.
Key Takeaways
- Toothpaste expiration is mainly about effectiveness rather than safety.
- Natural toothpastes without synthetic preservatives may expire faster than conventional options.
- Whitening toothpastes may have ingredients that degrade differently than regular formulas.
Explanation
Toothpaste expiration is mainly about effectiveness rather than safety. The active ingredients, particularly fluoride, degrade over time and become less potent. The American Dental Association recommends using toothpaste before its expiration date for optimal cavity protection.
Physical changes may occur in expired toothpaste: it may dry out, become discolored, separate, or develop an off taste. These changes make the paste less pleasant to use but do not make it dangerous. The abrasive and cleaning agents may also be less effective.
The FDA requires toothpaste to have an expiration date. Check the crimp of the tube or the box for the date. Stored properly (cap on, in a cool dry place), toothpaste should remain effective until its printed expiration date.
Things to Know
- Natural toothpastes without synthetic preservatives may expire faster than conventional options.
- Whitening toothpastes may have ingredients that degrade differently than regular formulas.
- Prescription toothpastes or those with specialized ingredients should follow dentist guidance on expiration.
