Does Mouthwash Expire? Here’s What You Need to Know
Does mouthwash expire ? Mouthwash is a staple in many people’s oral care routines. It helps freshen breath, kill bacteria, and reduce plaque. But like all products, mouthwash does expire.
Yes, mouthwash does expire, usually after 2-3 years. This is because the active ingredients in mouthwash, such as alcohol and essential oils, can break down over time, making the product less effective. Additionally, expired mouthwash may harbor bacteria, which can be harmful to your oral health.
How to Tell if Your Mouthwash Has Expired
Most mouthwashes will have an expiration date printed on the bottle. This date is usually accurate and should be your primary guide to whether or not your mouthwash is still safe to use. However, in some cases, the expiration date may be missing or illegible. If this is the case, there are a few other signs that can help you determine if your mouthwash has expired:
