No, you cannot bring a full tube of toothpaste through TSA if it exceeds 3.4 ounces (100 milliliters). The TSA adheres to the 3-1-1 liquid rule for carry-ons, meaning all liquids must be in containers of 3.4 ounces or less and must fit in one quart-sized, resealable bag. If your toothpaste is larger, it needs to go in your checked luggage.
