Rinsing your mouth with mouthwash will remove food debris and leave it clean and fresh.
But what about if you wanted to keep your Listerine mouthwash handy whenever you go or wanted to bring it with you on a plane on your next flight.
Here is the short answer.
Mouthwash will need to follow The TSA 3-1-1 liquid rule as it is considered a liquid, so you are allowed to bring containers of 3.4 oz / 100 ml or less inside a quart size bag, there are no limits to the amount of mouthwash you can bring in checked baggage.

Let’s dive right in.
TSA Rules On Mouthwash
The TSA does not specifically mention mouthwash on its website but they have a general rule about liquids.
But i checked Twitter for more clarifications and if there are any hidden rules, and here is what I have found.
Kyle needed to know if mouthwash in a 3.2 oz / 94.63 ml bottle is permitted in her carry on bag.
The TSA customer service replied : you can bring your mouthwash through the security checkpoint and in carry-on baggage in bottles that are or less than 3.4 oz / 100 ml and packed inside a quart sized bag.
Aliases wanted to know if her lotion and mouthwash are good to go in her carry on bag or personal item (backpack).
Generally the TSA do not regulate what bag to use or where to place your items ( in a backpack or suitcase ), but they do recommend to proper organize your items, making them easy to reach and speed up the screening process.
“Toiletries must be in containers that are 3.4 oz / 100 ml or less in carry on bags, you are allowed to take as many travel sized liquids as can fit into a single quart-sized zip top bag, larger containers need to be placed in a checked bag” they replied .
Tip: If you do not want to bother yourself with the airport liquid rules you can just take mouthwash tablets (Amazon link) and you are good to go.
But if you have a prescription from your doctor you can take more than 3.4 oz / 100 ml containers, just ensure that you present the doctor note so the security agent knows the reason why you are exceeding the allowed limits.
Take Mouthwash In Checked Baggage
There are no limits to the amount of mouthwash you can bring in checked baggage, whether it is Listerine, TheraBreath or any other brand.
Do not worry you can pack a full sized mouthwash bottles larger then 3.4 oz / 100 ml in checked baggage.
Even though most of the mouthwash liquids contain alcohol you won’t face any problem.
Alcohol with less than 24% alcohol content, are allowed in checked bags with no quantity limitations.
Take Mouthwash On International Flights
Traveling with mouthwash on international flights is almost the same as domestic flights, they must be in containers of or less than 3.4 oz / 100 ml (volume), 100 grams (weight) along with other toiletries.
The containers need fit and packed in a transparent 1-liter resealable zip top bag, which also known as a quart-sized bag.
There aren’t any restrictions for checked luggage, so you can bring large containers to your destination but not for commercial use.
Mouthwash is a liquid and the same rules that are applied for toiletries will also applied for your mouthwash.
No more than 3.4 oz / 100 ml or less for each container packed in carry-on baggage.
For checked baggage you don’t need to worry about the amount or even the size of your bootle, even though it needs to be reasonable and you take only what you will need for personal use.
