Can you carry-on a full size toothpaste?

Packing for a Flight: Toothpaste and the 3-Ounce Rule

Air travel often comes with a flurry of packing decisions, and one frequently overlooked item is toothpaste. While it’s perfectly acceptable to bring your toothbrush and toothpaste, the Transportation Security Administration (TSA) has a rule you need to keep in mind: all liquids, gels, and aerosols must be in containers of 3.4 ounces (100 milliliters) or less.

This rule applies not just to toothpaste, but also to items like lotions, shampoos, conditioners, gels, and even some medications. The rationale behind this is to prevent the possibility of security risks associated with potentially hazardous materials.

Therefore, while you can certainly take your toothpaste on a flight, it must be in a travel-sized container. Simply transfer your full-size toothpaste into a small, compliant bottle. These containers are readily available at pharmacies, drugstores, and many travel retailers. Be sure to check the label to ensure the container meets the 3.4-ounce limit.

This applies to all liquids, gels, and aerosols, not just toiletries. Make sure to adhere to this rule to avoid any delays or issues at security checkpoints. Take the extra minute to repack your toiletries into smaller containers, and you’ll be off to your destination in no time.
