Can You Bring Toothpaste on a Plane?

If you’ve ever stood at the airport wondering “Can I bring toothpaste on the plane?”  The answer is yes, but with some rules. Before you pack that travel tube, here’s everything you need to know about airline regulations, TSA guidelines, and how Remit Choice helps travelers like you move money easily across borders while you move around the world.

Why Toothpaste Counts as a “Liquid”

Even though toothpaste feels like a solid, it’s officially considered a liquid, aerosol, or gel (LAG) under international aviation rules. According to the International Civil Aviation Organization (ICAO), all such substances are subject to quantity restrictions when carried in hand luggage.

This rule exists to keep passengers safe and prevent potentially hazardous liquids from being disguised as personal care products. The European Commission on Transport also confirms that gels and pastes like toothpaste fall under these guidelines.

The “3-1-1” Rule for Carry-On Bags

In the United States, the Transportation Security Administration (TSA) enforces the 3-1-1 rule — a simple formula that applies to all liquids, aerosols, and gels:

• Each container (like a toothpaste tube) must be 100 mL or less (3.4 oz).
  
• All containers must fit into a 1-quart (1-liter) clear, resealable plastic bag.
  
• Each passenger can carry only one bag of liquids in their hand luggage.
  

You can read the full explanation on the TSA’s official website.

If your toothpaste tube is larger than 100 mL, even if it’s half-empty, it might be confiscated at the security checkpoint. Travelers have shared similar experiences on Tripadvisor, so it’s best to stick with travel-sized tubes.

What About Checked Baggage?

For checked luggage, the restrictions are much looser. The Canadian Air Transport Security Authority (CATSA) notes that liquids and pastes of any size can usually be packed safely in checked bags. Just make sure to close the cap tightly or double-bag your toiletries to prevent leaks.

Smart Packing Tips for Travelers

To make your next trip smoother:

• Check your departure country’s airport rules, as they may differ slightly. (EU Aviation Security Guide)
  
• Buy toothpaste after security if you need a full-size tube — duty-free shops usually sell items in tamper-evident bags.
  
• Try solid alternatives like toothpaste tablets or powder. They’re not considered liquids under TSA’s 3-1-1 rule.
  
• Keep your liquids bag near the top of your carry-on so you can easily remove it during security checks.
  
• If in doubt, ask a TSA officer before your flight.
  

Quick FAQ

Q: Can I bring an electric toothbrush with built-in paste?
Yes — but make sure the toothpaste part follows the 100 mL rule. For electric toothbrushes, check battery restrictions on TSA guidelines.

Q: Are toothpaste tablets allowed in carry-on luggage?
Yes. Since they’re solid, they usually bypass the 100 mL restriction. Learn more from Squaremouth Travel Advice.
