Toothpaste TSA Rules

The TSA does allow toothpaste through the security checkpoint and in carry-on bags.

But toothpaste is considered a liquid in the eyes of the TSA, that is why they limit the amount you can take in on board the airplane to 3.4 oz (100 ml) or less for each container.

How Much Toothpaste Can You Bring In Checked Baggage?

There are no limits to the amount of toothpaste you can bring in checked baggage.

You can pack larger containers more than 3.4 oz (100 ml) inside your checked bag and without even placing them inside a toiletry bag.

The good thing about playing toothpaste in checked baggage, is that you can take more than one full sized container, not only toothpastes but also, any liquid products like shampoo, perfumes etc…

You can take your toothpaste in either its original container or fill a small one, the container must be less than 3.4 oz or 100 ml when taking them in carry on baggage.

Generally, there is nothing wrong with toothpastes; however the TSA includes them in its 3-1-1liquid rule; and it is advised to stay within the limits and carry a small amount or travel size toothpaste inside a toiletry bag and avoid any inconvenience at the security checkpoint.

Here some tips on how to take your toothpaste on a plane:

  • choose the right size (under 100 ml), as the size is the factor for liquids in carry on.
  • If you can travel with the original container that will be a good idea, because the airport security agent will quickly identify the item without a manual or additional inspection.

Why Is Toothpaste Not Allowed On Airplanes?

The fact that some passenger think that toothpaste is not allowed on planes is not correct.

The TSA does only limit the amount of toothpaste in carry-on baggage.

And not juts toothpaste anything that you can pour, pump, spread, squeeze, smear, spray, or spill is considered a liquid and must follow the 3.4 ounces (100 ml) or less rule, and apparently toothpastes can be squeezed.

The reason of banning large quantity of liquids like toothpaste is for security reasons, terrorist attacks or bad guys can use those kind of liquids to made or hide an explosive.

So don’t take it personal it is just for safety and the security of the passengers a and the aircraft.

There are attempts that involve liquids, acids or explosives that the security can not detect if they are in large quantities, so the TSA and other security tend to ban taking more than a personal use on board the airplanes.

Can I Use My Toothpaste On a Plane To Brush My Teeth?

Yes.

You can brush your teeth on your flight, and it is advised to clean and rinse your mouth especially if you have a meal or eat sugary foods.

it is even preferable to brush your teeth twice on long haul flights, (like US to Australia, or China to Canada)

Bye-Bye Quart-Sized Baggie For TSA!!

There is a trend of toothpaste tablets on Amazon among travelers, because you can take any amount of tablets on carry-on baggage and on planes without any limits.

A traveler says about the tablet toothpaste “These are part of my standard conference travel packing. I use a single hard-case suitcase that fits in an overhead bin, and the only thing I hate worse than checking a bag is having to fish out a baggie of liquids for inspection by the TSA. So I pack toothpaste tablets, sometimes I use also the hotel toothpaste , for other hygiene needs (conditioner makes for great shaving cream), and never worry about it. My bag stays closed, one less thing to meddle with.

Final Thoughts On Taking Toothpaste On a Plane.

You can bring toothpaste on planes but in certain limits.

When you pack toothpaste in carry-on ensure that the tubes are 3.4 ounces (100 ml) or less and placed inside a quart-sized bag.

There are no limitations on toothpaste in checked baggage.

And If you are traveling to a place where you know there are no toiletries or you will need to pay some extra money to get your toothpaste, it may be smart to pack an extra tube of toothpaste in your checked baggage, especially if local shops are difficult to find or you don’t like a certain brand.
