When it comes to traveling, whether it’s for business or pleasure, there are certain essential items that we all need to pack. From clothes and toiletries to gadgets and accessories, the list can seem endless. However, one item that often gets overlooked but is crucial for maintaining good oral hygiene is toothpaste.


While packing toothpaste may seem like a simple task, it’s important to be aware of the regulations and restrictions when it comes to air travel. The Transportation Security Administration (TSA) has specific guidelines in place to ensure the safety and security of passengers, which includes restrictions on the size and packaging of toothpaste that can be carried onto an airplane.


In this article, we will explore the rules and regulations regarding toothpaste and air travel, as well as provide some TSA-approved travel toothpaste options and essential tips for traveling with toothpaste. So, if you’re planning your next trip and want to make sure you have all your travel essentials in check, read on to find out more!


The TSA’s 3-1-1 liquids rule

Before diving into toothpaste size restrictions, it’s important to understand the TSA’s 3-1-1 liquids rule. This rule applies to all liquids, gels, creams, and aerosols that you plan to bring in your carry-on luggage.


The 3-1-1 rule stands for:

  • 3: Each passenger is allowed to carry containers of liquids, gels, creams, and aerosols that are 3.4 ounces (100 milliliters) or less.
  • 1: These containers must all be placed in a single, clear, quart-sized plastic bag.
  • 1: Each passenger is allowed only one quart-sized bag of liquids.

It’s important to note that the 3.4-ounce limit applies to the container size, not the amount of liquid inside. So, even if your toothpaste tube is only half full, if the container itself is larger than 3.4 ounces, it will not be allowed through security.


Additionally, the quart-sized bag with the liquids must be placed separately in a bin during the security screening process. This allows the TSA officers to easily inspect the liquids without causing any delays or additional screenings.


It’s crucial to adhere to this rule to ensure a smooth and efficient experience during the security checkpoint. If you fail to comply with these regulations, you may be required to discard your toothpaste or other liquids that do not meet the requirements.


Toothpaste size restrictions

When it comes to toothpaste, the TSA follows the same 3-1-1 liquids rule as mentioned before. This means that your toothpaste must be in a container that is 3.4 ounces (100 milliliters) or less and it must be placed in a quart-sized plastic bag with your other liquid items.


It’s important to note that the TSA does not make any exceptions for toothpaste, regardless of whether it’s a travel-sized tube or not. So, even if your toothpaste tube is smaller than 3.4 ounces, it still needs to follow the rules and be placed in the quart-sized bag.


Keep in mind that the 3.4-ounce limit applies to the individual toothpaste container. If you need to bring a larger amount of toothpaste, you may consider transferring it into smaller travel-sized containers that meet the TSA regulations.


If you have a larger tube of toothpaste that exceeds the 3.4-ounce limit and you don’t want to transfer it into smaller containers, it’s best to pack it in your checked luggage. There are no size restrictions for toothpaste in checked baggage, but it’s always a good idea to place it in a sealable plastic bag or wrap it in a plastic wrap to prevent any leaks or spills.


By following these size restrictions, you can ensure a hassle-free experience when going through airport security and avoid any potential issues with your toothpaste.


TSA-approved travel toothpaste options

If you prefer to travel with pre-packaged travel-sized toothpaste, there are plenty of TSA-approved options available on the market. These toothpaste options are specifically designed to comply with the 3-1-1 liquids rule and come in convenient sizes that are perfect for your carry-on bag.


Many popular toothpaste brands offer travel-sized versions of their products, which conveniently come in 3.4-ounce or smaller tubes. Look for toothpaste tubes that are clearly labeled as “travel size” or “TSA-approved” to ensure that they meet the size requirements.


Another option is to opt for toothpaste that comes in solid form. Solid toothpaste, also known as toothpaste tablets or toothpaste pills, are compact and do not count as a liquid or gel. These tablets can be chewed or crushed and then used with a wet toothbrush to create a paste-like consistency.


Furthermore, there are toothpaste powders available, which also do not count as a liquid. These powders can be sprinkled onto a wet toothbrush or mixed with water to form a paste.


Both solid toothpaste tablets and toothpaste powders are great alternatives to traditional toothpaste tubes and can easily fit into your quart-sized plastic bag without taking up much space. Plus, they eliminate the risk of leakage or spillage during your travels.


It’s also worth noting that some hotels and accommodations provide complimentary travel-sized toothpaste, so you may want to check in advance if your accommodation offers this amenity.


Ultimately, the choice of TSA-approved travel toothpaste is up to personal preference. Whether you prefer traditional travel-sized tubes or innovative solid or powdered options, there are plenty of choices available to ensure you can maintain your oral hygiene routine while adhering to TSA regulations.


Tips for traveling with toothpaste

Traveling with toothpaste doesn’t have to be a hassle if you follow these helpful tips:

  1. Choose the right size: When purchasing toothpaste for your trip, opt for a travel-sized tube that meets the TSA’s 3-1-1 liquids rule. This will ensure that you can easily pack it in your carry-on bag without any issues at the security checkpoint.
  2. Use leak-proof containers: To avoid any potential leakage or spillage, it’s best to place your toothpaste tube in a leak-proof container or wrap it in plastic wrap. This will prevent any mess and ensure your other belongings stay clean and dry.
  3. Organize with a quart-sized bag: Place your toothpaste along with other liquid items, such as shampoo and lotion, in a quart-sized plastic bag. This will keep everything organized and easily accessible during the security screening process.
  4. Consider alternative forms: If you’re concerned about the size or potential leaks of toothpaste tubes, consider using solid toothpaste tablets or toothpaste powders. These alternatives are TSA-approved and eliminate the need for a liquid container, making them convenient and mess-free.
  5. Plan for longer trips: If you’re traveling for an extended period and need more toothpaste, consider packing a larger tube in your checked luggage. Just make sure to place it in a sealable plastic bag or wrap it in plastic wrap to prevent any spills.
  6. Check hotel amenities: Before packing any toothpaste, check if your hotel or accommodation provides complimentary travel-sized toothpaste. This can save you space in your luggage and ensure you have what you need upon arrival.
  7. Keep travel-sized toothpaste stocked: If you frequently travel, consider keeping a stock of travel-sized toothpaste so that you always have a supply ready for your trips. This way, you can easily grab a tube when it’s time to pack without having to worry about making last-minute purchases.

By following these tips, you can ensure a smooth and stress-free experience when traveling with toothpaste. Maintaining good oral hygiene while on the go has never been easier!



Traveling with toothpaste is an essential part of maintaining good oral hygiene while on the go. However, it’s important to be aware of the regulations and restrictions imposed by the TSA when it comes to packing toothpaste in your carry-on luggage.

In addition to traditional travel-sized toothpaste tubes, there are also solid toothpaste tablets and toothpaste powders available that are TSA-approved and offer convenient alternatives. These options not only save space in your quart-sized plastic bag but also eliminate the risk of leaks or spills during your travels.

Planning for longer trips may require packing larger tubes in checked luggage, ensuring they are properly sealed to prevent any mishaps.


Traveling with toothpaste doesn’t have to be complicated or stressful. With a little planning and knowledge of the rules, you can keep your oral hygiene routine intact while ensuring compliance with airport security measures.
