Answers: does mouthwash expire?
Yep, it's a stupid question!
Actually it isn't - check the bottle as it should have an expiration date on it. Really no harm in using it after that. Jusy may not be as effective.
i mean only if youve had it for like ever but honestly who stores mouth wash for like 3 years
Mouthwash in a closed container will last for years.
