#58: Mouthwash
Colgate reveals that mouthwash, particularly therapeutic mouthwash, has an expiration date. These mouthwashes are formulated to combat harmful bacteria and tackle dental issues such as dry mouth, plaque, receding gums, and gingivitis. They generally contain an antiseptic ingredient and a significant amount of water.

Therapeutic mouthwashes may diminish in effectiveness over time, eventually becoming ineffective. Similarly, regular antiseptic mouthwashes can lose their effectiveness, transforming into nothing more than flavored water once they’re past their prime. To ensure its efficacy, it’s recommended to replace your mouthwash within three years from its production date.
