Yes they do. I have listerine whitening strips that are expired. There should be something on the box.
It depends on what kind of mouthwash it is. Non-alcohol? Or alcohol? Non-alcohol does expire. Mouthwash with alcohol in it expires too. I have Listerine and it has an expiration date on it, and it does contain alcohol.
Yes, Listerine does expire, typically around three years after the manufacturing date. While it may not taste like soap, expired Listerine can lose its potency and flavor, potentially becoming less effective at killing germs. It shouldn't bubble up in the bottle under normal conditions, but any unusual changes in appearance, smell, or consistency may indicate it's no longer safe to use. Always check the expiration date before use.
