TSA Approved Toothpaste (3-1-1 Rule Explained)

Packing your toiletries is just as important as packing your clothes and shoes. But there are certain rules that you need to adhere to, when you’re packing a suitcase that you intend to use as a carry-on when flying.


At A Glance: Our Favorite TSA Rule Toothpaste Ideas


Did you know that if you bring your regular, full-sized tube of toothpaste in your carry-on, it will most likely end up confiscated? And that also applies to shampoo, conditioner, bottles, and pretty much all other liquids and gels.

If that is news to you, you have a lot to learn. And you are in luck that you found this post because we know everything about packing a TSA-approved toiletry bag, and we’re dying to share it with you!

What Size Toothpaste Can You Take On A Plane?

You can take a 3.4 ounce container of toothpaste with you on the plane. Toothpaste counts as liquid or gel and comes under the 3-1-1 TSA rule.

The 3-1-1 rule refers to the number of toiletries that you are allowed to pack in your carry on bag – you can bring 3 (3.4 to be precise) ounces of liquids and gels, in 1 clear plastic bag, and you are allowed 1 such bag per person.

Technically, you can bring as many 3.4 ounce containers as you can fit in the bag – as long as you don’t push it because the TSA agents still have the final say.

It is very important to note that this rule only applies to carry-on luggage, and not to checked baggage.

There are certain exceptions to the rule and ways around them, and I’ll tell you all about those. But first, let’s check out what the best TSA-approved toothpaste and containers are.
